Bike Counts for the M year (or for the '91 model year)

Postby David W » 04 Apr 2017, 02:58

Details to follow later, but the bottom line is: 5963 bikes for model year 1991, or for year code M.
That model year, 1991, is generally associated with the second wave, or second vintage of Pans/STs.
And that is a world total of both Pan 1100s and ST1100s.
(However, some 1508 of that 5963 total are launch models for the USA; and the launch is usually associated with the 1990 model year, not with 1991.)

The corresponding total for model year 1990, or code L, is 6795 bikes.
Comparing that 6795 to 5963, it would look on the face of it that there was only a modest decrease in the bike count, going from 1990 to 1991: 6795 down to 5963.
But to dig a bit deeper, we can add the term Vintage to our Pan/ST vocabulary.

Two bikes are of the same Vintage if their parts lists are the same, except for national differences (such as body paint colour).

We can call the collection of launch bikes the 1990 Vintage. *
We can call the post-launch vintage, or the second wave of bikes, the 1991 Vintage.

The 1990 Vintage consists of all the 1990/code L bikes, which are all launch bikes, plus those 1508 USA launch bikes that Honda branded as 1991/code M. That is 6795 plus 1508, or 8303 total bikes in the 1990 Vintage. **

The 1991 Vintage is all 5963 of the 1991/code M bikes, minus those same 1508 USA launch bikes, for a bike count of 4455 bikes. (For example, all non-USA, 1991 or code M bikes are 1991 Vintage.)

In summary:
8303 bikes in the 1990 Vintage, generally associated with model year 1990/code L, and
4455 bikes in the 1991 Vintage, generally associated with model year 1991/code M.

So there was actually a BIG drop in the bike count, going from the 1990 Vintage, to the 1991 Vintage: 8303 down to 4455.

Even so, Honda built 8303 plus 4455, or some 12 758 total bikes, during only the first two model years of the Pan/ST Line!

Yikes ... I mean ... blimey, if one lined more than twelve thousand of those bikes up, end to end, the resulting line of bikes would be ... quite a long line, no? (And when those bikes were new, that line was worth a lot of money, no?)

------------------------------------------------Red Line (beyond which are only details)-----------------------------------------------------------------------------------------------------------------------------------------
The term "model year" used here is short for the term Honda model year, which is the year that Honda assigns to a bike. (For example, Honda may have assigned model year 1991 to a bike by assigning that bike only the year code M during manufacturing, but the code M is just an abbreviation for the model year 1991.)

* For example, a fine parts list for most of, or for 6795 bikes of, the 1990 Vintage can be found on the page called ST1100L (1990) Parts Fiches, which can be found here:
http://www.st-1100.com/st1100l.html . (All that that nearly universal parts list lacks is mention of those 1508 USA launch bikes, which are 1990 Vintage as well.
Any American feel up to the task of adding those USA, 1990 Vintage bikes into that parts list?)

** We have a thread here called A Listing of the NUMBERS from the Launch that is all about those 8303 bikes of the 1990 Vintage; here is a link to it: viewtopic.php?f=9&t=14305

Bike Counts by Region (for both the L and M years)

18 miles high. That is over 29 kilometers up! (A bit dizzying.) But back now on terra firma, we noted in our first post that the bike count did not exactly take off and soar at high altitude right after Honda finished building their 8303 launch bikes. We saw instead a decrease in the global number. Now we look at the numbers by region, and we will see the same pattern (one of falling, rather than soaring).

The bike counts by region for the 1991 model year are:
Spain: 169 Pan M models, and
Europe other than Spain: 3230 Pan M models.
USA California: 386 ST1100s,
USA other than California: 2128 ST1100s, and
Canada: 50 ST1100s.
Australia: no M models of record.
Those numbers total 5963 bikes for the M model year, the model year 1991, as stated in the first line of this thread. Now we change from the '91 model year to the '91 Vintage.

--------------------------------------------------------------------------------------------------------------------------------------
1991 Vintage. The bike counts by region for the 1991 Vintage are different only for the USA (compared to the numbers just above):

Spain: 169 Pan M models, and
Europe other than Spain: 3230 Pan M models.
USA California: 145 ST1100s,
USA other than California: 861 ST1100s, and
Canada: 50 ST1100s.
Australia: no M models of record.
Those numbers total 4455 bikes for the 1991 Vintage, or post-launch Vintage. Now we look at the 1990 Vintage, or launch Vintage, for comparison.

------------------------------------------------------------------------------------------------------------------------------------------------
1990 Vintage. The bike counts by region for the 1990 Vintage were:

Spain: 600 Pan M models, and
Europe other than Spain: 5840 Pan M models.
USA California: 241 ST1100s,
USA other than California: 1267 ST1100s, and
Canada: 200 ST1100s.
Australia: 155 ST1100s.
Those numbers total 8303 bikes for the 1990 Vintage, or launch Vintage. Now we can compare those 1990 numbers with the 1991 numbers just above.

---------------------------------------------------------------------------------------------------------------------------------------------------
Going from '90 to '91, we see nothing but decreases:

Spain dropped from 600 to 169 Pans, and
Europe other than Spain dropped from 5840 to 3230 Pans.
USA California dropped from 241 to 145 STs;
USA other than California, from 1267 to 861 STs; and
Canada dropped from 200 to 50 ST1100s.
The Australian count also fell, from 155 launch ST1100s, to none in the post-launch Vintage of '91.

And all of those decreases added up to ... a global decrease (going from the 1990/L Vintage to the 1991/M Vintage) .
-----------------------------------------------------------------------------------Red Line (beyond which are only bloody details)-----------------------------------------------------------------------------------------------------------
Details: We are using 3230 as the ending 1991 frame number for Switzerland whereas the Swiss published 1991 ending number is 3320. Before making that change, which amounts to 90 fewer Pans built, we looked closely at engine numbers, to be sure that the engine counts are consistent with the frame or bike counts. Thus, production for the M year ended with the building of only 10 Swiss Pans, not with the building of 100 of them. (Justification for this is given below in the post called Zooming in Now on the ENDING Production of M Models which is dated 21 Aug 2017.) Speaking of engine numbers, it looks as if the starting engine number for Germany was about 1521 whereas the published German number is 0001. In other words, we are pretty sure some 1508 USA launch ST1100s were built before Honda built the first German M model (which is a post-launch bike). For more on that, see the beginning, items numbered 0 and 1, of the post below called Downshifting now for some Early M year Manufacturing DETAILS dated June 25.

Bike Counts for the individual European markets are rare.

Postby David W » 22 Apr 2017, 21:02

As was the case for the previous L year, 1990, it is generally not possible to give bike counts for the M year, 1991, for all eleven European markets. The one exception we have seen, for both years, is Spain.
Spain imported 169 Pan M models for 1991. We noted above that 169 is down from the bike count of 600 Spanish Pan L models for 1990.*

The only exception for year 1990 was Norway, importing a modest 15 Pan L models. For 1991, it appears that Norway imported at least 20 Pan M models. (So we can at least say there was a Norwegian increase, from 1990 to 1991.)

The main exception for 1991 is Switzerland. Switzerland imported 160 Pan M models. (The Swiss count is the sum of a main batch of 150 plus a final batch of ten Pan M models. For the previous year, 1990, I think we only had a count for the Swiss initial batch; need details?)

Italy might be a second exception. Italy got an initial batch of 225 Pan M models, plus a final batch of 196 to boot. So Italy got at least 421 M year Pans.

If that Italian number seems impressive, Germany imported a first batch of 455 Pan M models; then Germany imported at least one more batch, a final batch for which we have no count. (The UK's initial batch was 232. The UK also imported a later batch of M year Pans, but no exact count seems available for it, either.)

For all of the above bike counts, both frame and engine numbers are available, for any member of this site.

-----------------------------------------------------------------------------And now, some bloody details------------------------------------------------------------------------------------------

* Spain is an exception because Spain's Pan frame numbers were always VINs, or Vehicle Identification Numbers. (Not so for the other ten Euro markets, not until model year 1996, or year code T.)

The bike count of ten Pans for the Swiss final differs from the Honda number, which would have it be 100 Pans instead of 10, as was noted in the bloody details in the post just above this one. (Justification for the lower Swiss count is given below in the post called Zooming in Now on the ENDING Production of M Models, which is dated 21 Aug 2017.)


The bloody details for the previous L year, 1990, are in the nearby thread called Some history: L models Led the Launch of the Line in most Lands, which starts on this page: viewtopic.php?f=9&t=13969

Downshifting now for some Early M year Manufacturing DETAILS

Postby David W » 25 Jun 2017, 21:36

0. Production of M year or 1991 models began way back in about February of 1990 with the early, launch versions of two American models, namely:

* Frames JH2SC261*MM100005 to JH2SC261*MM100245, or 241 bikes, were built as the early version of the California, 1991 USA M model; and
* Frames JH2SC260*MM100004 to JH2SC260*MM101270, or 1267, bikes were built as the early version of the 49-state, 1991 USA M model.

The starting engine number for these was SC26E-2100009.
(Thus, eight engines, numbers SC26E-2100001 through SC26E-2100008, were built but were not fitted to bikes that made it to market. They were used in part to build seven 1991 US bikes that were built but not sent to market.)

Because there are so many numbers involved here, we have started putting all bike counts in larger print.

This production of 1508 total (or 241 + 1267) USA launch bikes ended in about May of 1990 with the use an engine with estimated engine number SC26E-2101516.*
No more M models were built until later, after the production of L models (or 1990 model year, or launch bikes) ended in about July, 1990 with the completion of the Australian launch STs.

1. Probably without much delay after the L models were completed, production of M models then resumed with the building of 455 German Pan M models, starting with frame number

SC26-2100001, and ending with frame
SC26-2100455. These were not launch bikes; they were second wave vintage, constituting the first of the "true '91" or "true M" bikes. As for the starting German engine number, it appears that four more test engines were first built; then engine SC26E-2101521 became the first engine put into a German Pan M model. (Although that starting engine number disagrees with the published one, which is SC26E-2100001, there is some evidence that the ending German engine number for this initial, German batch was SC26E-2101975.)

After that initial batch of 455 German Pan M models was built, Honda had basically just used engine SC26E-2101975 to build a German Pan with frame number SC26-2100455; then Honda started building UK Pan M models.

2. Honda then built 232 Pans for the UK, starting with frame number SC26-2100456 (or one frame number more than the ending German one mentioned).

3. Then Honda built 225 Pans for Italy;

4. Then they built 50 for France;

5. And then they built 94 for European Direct Sales (or ED for short), ending with frame SC26-2101056 and engine number about SC26E-2102576.

The above are partial yearly counts; all the markets mentioned received additional M models later. Honda has just built ED frame SC26-2101056 and engine SC26E-2102576. We continue this detailed history with our next post below; see specifically item 6 there.

-----------------------------------------Red Line (followed by bloody details)------------------------------------------------------------
*A sample USA ST1100 from this early production period is frame number or VIN
JH2SC2604MM100028 owned by Al Hostettler of Ohio, USA, which he purchased in June of 1990. (His frame number falls between
JH2SC260*MM100004 and JH2SC260*MM101270, which is the second of the two VIN ranges given above, near the STart of this post.)
As for the first of the two above VIN ranges, a sample is VIN
JH2SC2616MM100170 owned by Andy Corcoran of California, USA, which he bought in October of 1990.

A sample of an early built German M model is frame SC26-2100023 owned by Timo Gronman of Finland, or Suomi. (If you ever contact him, ask for his engine number, please.)

More Slow Going, Reporting on Early or Middle '91 Production

Postby David W » 19 Jul 2017, 00:40

We continue here where we left off in the last post above. (Item 6 below follows item 5 in that previous post.)

After the early production reported in the post just above this one, the production records get foggy until near the end of production of M models. We plan to gloss over many of those foggy details, which include production of the 50 Canadian M models and the two remaining versions of the two USA M models, which totaled 1006 bikes for the US, all in about late September or October, 1990.

Here are the events we generally cannot look at in great detail:

6. After the EDS batch, Honda built 607 engines that were used to build 523 non-Spanish Pan M models; and some (probably 10) initial Spanish Pan M models; and all 50 of Canada's 1991 ST1100s. The 523 included all of Northern Europe's (ND's) Pan M models. (Those numbers leave probably 24 engines unaccounted for; we speculate that those 24 were used for 10 each of the two USA later, post-launch '91 versions, plus a batch of four more test engines. And the month was about September, 1990.)

7. Then the fog clears long enough to see that Honda built 150 more engines that were used to build 150 Swiss Pan M models, as Switzerland's initial batch.

8. Then the fog rolls in again while Honda mass produces 1802 more engines, only 660 of which we can see were used to build non-Spanish Pans. Those 660 Pans included Austria's initial batch of M models; Germany's final batch, and Finland's initial batch. Bike production for this period 8 started with Austria's initial batch, but that seems to consist of at most about 46 Pans. Honda then switched to building USA ST1100s, about 851 of them, and mostly for the US "49-state" model. After those were built, Honda worked on building the California model but did not complete it before starting on the Finnish Pans. Then Honda interrupted Finland's production to complete the California STs, about 135 of them for this period. The month was about October, 1990. Production for this period number 8 ended with the final batch of German Pan M models.
So the bulk of the 1802 engines were used to build the rest of the USA's later two versions of the two American 1991 ST1100 models. The two US bike counts for this period bring the number of unaccounted-for engines down to 156 engines, all of which were probably used to build an estimated 156 Spanish Pan M models, bringing the M year's total of Spanish Pans to about 166. (The final Spanish count for Spain is 169 Pan M models, so Honda was not quite done with Spain.)
All of that brings us up through German Pan number SC26-2102389 and German engine number SC26E-2105135. And then the fog subsides a bit.

9. As the fog lifts, we can see that Honda built 196 Italian Pan M models, using 196 more engines in the process, and completing Italy's yearly quota.

10. Some fog returns as Honda builds 299 more engines and uses them to build 299 non-Spanish Pan M models. This batch included both the initial and final batches for Norway; Norway's final batch contained 10 Pans. It also included the final UK batch of Pans, and it probably included the final batch of Finnish Pans. (Finland's ending engine number is for a 1992 engine and is otherwise inconsistent with the ending frame number. So we can't clearly see Honda's finish with the Finnish.) All of this brings us up through Norwegian Pan SC26-2102884 and Norwegian engine number SC26E-2105630. Only five markets have not yet had their yearly quotas met. They are: France, Austria, Spain, EDS and Switzerland.

11. Honda then built a 250 Pans for France's final batch, using up 250 more engines to do so.

12. Honda then built 6 Pans, as Austria's final batch.

13. Honda then built 3 engines which, by the process of elimination, probably were used to build Spain's final 3 Pan M models. (Spain's yearly total is known to be 169 Pans.)

All of that made Austrian Pan frame SC26-2103140 and Spanish engine SC26E-2105889 the last that have been accounted for so far in this history.
And there were only two markets left that had not yet received their final batches of bikes: European Direct (or ED) and Switzerland.

We will pick up next time with the final production details for those two remaining markets, of which the Swiss one is the one where Honda seems to have made a 90-bike error when reporting frame numbers.
---------------------------------------Red Line--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
The USA bikes in item 8 are the "later" versions of the two models mentioned. The "early" versions of those same models were discussed above in item 0 in the post just above this one.
The above results 6 through 10 use both beginning and ending frame and engine numbers supplied by Honda to their Parts Departments. Results 11 thru 13 use ending frame and engine numbers. For reports of those numbers, see for example, the Honda parts site cmsnl.com . (Search for "1991 ST1100" there.)

Zooming in Now on the ENDING Production of M Models

Postby David W » 21 Aug 2017, 21:15

We continue where we left off in the last post above. That post and the one above it contain relatively unimportant details whereas this post has the result that affects the bike counts for 1991. (Item 14 below continues on from item 13 in the post just above this one.)

14. Honda then built 80 Pan M models, as their final 1991 batch for European Direct (ED). The last frame number for those was SC26-2103220; and the last engine number, SC26E-2105969.

15. The records show Honda then built only ten more engines, numbered SC26E-2105970 through SC26E-2105979. They fitted those ten engines to Swiss Pans starting with number SC26-2103221. They must have run out of engines when they got to building the tenth Swiss Pan in this final batch, namely number
SC26-2103230, making that number the ending Swiss frame number, and the last non-Spanish Pan frame number, for 1991.

Honda however, has consistently reported frame number
SC26-2103320 as the ending Swiss frame number for '91. But there were not enough reported engines built, to build the extra 90 (or 3320 minus 3230) Swiss Pans that Honda mentions. Nor would we expect the Swiss market to import one hundred final Pans, after Switzerland had already imported 150 Pans earlier. (See item 7 in the post just above this one. See also items 12 and 13 there, for the small sizes of Austria's and Spain's final batches.)

Comparing those two possible, ending Swiss frame numbers,
3230
3320
,
Honda must have swapped the two middle digits and thereby made a typographical error.

So our conclusion to all of M year production is:

Honda finished the M year production by building 10 Swiss Pan M models, which brought the Swiss total to 160, and brought the non-Spanish Pan total to 3230 for the M year 1991.

The global total for 1991 was 5963 bikes, as stated in the first sentence of this thread. For the breakdown of that global total, which includes the 3230 count just mentioned, see the start of the post above called Bike Counts by Region (for both the L and M years) and dated 10 April, 2017.

---------------------------------------Red Line, beyond which are only Details--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
The above final results, numbered 14 and 15, use ending frame and engine numbers supplied by Honda to their Parts Departments. For reports of those numbers, see for example, the Honda parts site cmsnl.com . (For example, search for "1991 ST1100" there .)
