Serial number ID guide by Graham Weeks

Hello,
My son and I made a barn find yesterday of a Bridgestone motorcycle. I am trying to identify and date the bike. I read the serial number guide, which indicates the bike is a BS175. The milestone dates would indicate it was built in February 1966 but the milestones are for the UK ??? I am confused by that. Could someone please explain?
Thx
-
My GTR is titled as a 1969, but the vin is in the 1200 range - so is it likely a 67 that didn't sell until 1969?
-
Ole Smokey,I'd need to look into it to be exact,but the 21 designates 350 GTO and GTR,I'm pretty sure. I think you need to give me the letter to derive the year/month. It gets a bit goofy. I'll look at it after dinner. Thanks,Mark.
-
Mark, I had looked enough to see that my 21S021xx claims that it should be a July '67 bike, but the title is for a '69. However the 21xx sequence number also seems to point to a '67 bike.
Guess it sat unwanted for 2 years!
I could start a post to see who has the lowest # vin for a GTR.
-
Now I see,Smokey. The date code along with the # series looks that way. With shipping delays from Japan,coupled with rockfords distribution woes its possible this bike didnt make a dealer till sometime in '68 anyway. New vehicles are titled here for the upcoming year starting in July sometimes. So lets say it reached the dealer Feb/March of '68 than sat till july or aug. then titled for the upcoming year,your there. It might not have sat as long as you think. Heres something else to consider,if you are not the original owner and the bike had to be re-titled at some point,info was real vague on all this for a long time. So without the later '70 numbers system,no exact year was affixed and most people,even title agency's,etc.would have a nearly imposible task of figuring it out. So you pick a year and process the vin and keep rolling! Compiling vins is a good way to go,but not too many people care to share thier complete numbers. I've studied on this quite a bit and just when you think your getting a grip on it... Hope some other guys are forthcoming. Mark.

Comparing the numbers between the headstock and engine on my GTR shows a difference of 92. The serial number on the riveted tag falls between those two.
So Graham's guidance seems very accurate and most likely my engine and frame are the same pairing that left the factory.
But I realized that before I got the bike someone at the DMV transposed the serial number.
The paperwork says 21S021xx , but it is really 21S012xx
Don't look for me at the DMV trying to get that changed!
Very definitely a 67 model that was titled as a '69.
-
My 350 GTO 21W069XX is titled as a 1970. The serial number would indicate a 1968-69 manufacture. It also has the stamp on the front steering tube. So it all fits.
regards charlie

My 175 is titled as a 69. The serial# is 16M24xxx, which should put it in 67.
-
I'm not knocking Graham Weeks VIN ID article but I'm a little confused by it. My VIN tag is 21T01934 can someone give me in their best judgement what year my bike was produced as I'm heading to the titling red tapers and I want to shoot for a title in the correct year. Any help would be appreciated.
Thanks
Mike
-
Mike, I'd guess your GTR was made in 1967 from how I read his decode. The 21T should be an odd numbered year, and the milestone for 21S was July 1967. Mine is 21S012xx so maybe Aug-Sep 1967?
This guess also matches with the info for the GTR that toystoretom found on ebay in the UK.
-
Hi, Folks.
Don't get confused by whether the bike is from the UK, USA or anywhere else. The factory used a continuous serial code sequence, and simply shipped batches to different markets as they came off the production line. In fact, the milestone dates I listed were taken for convenience from my machines or from those owned by friends, but all the bikes came off the same factory production line in Japan.
-
I am a little confused on the VIN description as well. My tag on the side of the bike reads" 18C001848" meaning the first two digits claim it is a 90 sport oil injection. OK so far, then the "C" designates it as March in an even year? The bill of sale says the bike is a 1965 so this is not correct? What does the rest mean "001848"?
-
Hap,
There is some reading between the lines, but the "C" would be for March of an even year. For your 90 that would mean it was assembled in March 1964, and as mentioned in an earlier discussion, it then took that long to ship to the US, sit on a showroom floor and be sold so it was considered a 1965 for paperwork purposes by the dealer.
If you were starting with no paperwork and trying to get a title you could claim it was a '64, but if you have paperwork already documenting it as a '65 there's no real value in bothering to change it.
Your 001848 number is the sequential manufacturing of that model.
On page 2 of the serial number decoder, there is a milestone for a BS90 Sport with serial number 007418 as being made in March 1966. That helps to show that your 001848 was made in 1964.
-
Hi, Folks.
Confusion reigns! You're correct that "18C001848" means a Jet-Lube 90 Sport, built in March of an even year - buand that year was 1966. Jet-Lube Bridgestones weren't around in March 1964, and by March 1968 the 90 Sport had been superseded on the production line by the BS100 Sport model.
The "07418" number mentioned Old Smokey is an earlier pre-mix fuel 90 Sport, and had a serial prefix of "14". Presumably, whoever filled out the original bill of sale got it wrong.
As for the "001848" bit - your bike would have followed "18C001847" off the production line, and the next one in line was "18C001849". It's a s simple as that.
Hope that answers your question,.
Graham
-
My 90 is an oil injection. Is that what you mean by a jet lube? Your saying oil injection wasn't made in March 1964? Then the C would make it the next even year (March 1966)?
-
Hap,
Yes, you're dead right! "Jet Lube2 was Bridgestone's trade name for their oil injection system. Over here in the UK, the 90 and 350 oilers had "Jet Lube" stickers on the side panels instead of the silver "OIL INJECTION" labels. I guess the US bikes never used the "Jet Lube" name.
When trying to date a particular bike, it's important to remember that each model used its own sequence of serial numbers (the "01848" bit in your case). A 175 built in March '66 would have had a "16C" prefix and a 50 Sport "12C", but the serial numbers would have been nowhere near 01848. THe serial number simply stated at 000001 with the first of the model off the prodcution line, and incremented by one on each following bike built. Your 90 Sport was built in March '66 and happened to be the 1,848th example built.

The 'Jet Lube' Sticker was used in Australia also (see the blue 1968 BS 100 Sport in the Gallery on page 2).
On the 175DT the 'Oil Injection' sticker was on the key side panel and the 'Jet Lube' sticker was on the oil tank.

I have seen a few frames with serial numbers up above 37000, which exceeds the number of BS175s built. These are early model BS200 frames, presumably usiing up the surplus stock of frames originally intended for use on BS175's.

I'm not 100% sure about the serial "23V 07599". I originally had it noted in my list as "23V 10599", but that serial far exceeds the BS200 production run, which I believe was around 7800 bikes. I've made an educated guess that this serial was mis-read from the plate on the bike, and "7599" seems to fit in nicely with other figures.

Serial number 6800 was taken from a Dealer Service Letter describing mods to the Carburettor Float Pivots on the production line. It mentioned that all bikes from "21..06800" would be fitted with the modified carbs. The serial didn't include the month code, but the Service Letter was dated February 1969 and so I originally guessed at "21N" (i.e. February 69) for ths serial. BS350s were built in discrete batches, and it is lokely that the service letter was issued while the 350 production line was closed down, and refers to carb mods to be made from the start of the next production batch. Thus I now suspect that 21..6800 hadn't been built at that time, and probably was the first of the production batch built at the end of 1969 - which would probably make it 21V6800 or 21W6800 (Oct or Nov '69) - unless, of course someone out there knows different! Thanks to Brian the Brit for spotting this one.

November, 1970 from what i can see.
-
Hi,
Yes, your bike, serial number 23 K 04859, was built in November 1970.
"04859" lies between two known serial numbers "3732" (23 A - Jan 1970) and "6572" (23Q - May 1971). The only "K" month in the middil is November - hence November 1970.

I traded a 1968 Blue BS 100 Sport for a new Hodaka 100B+ in 1972-73 at Maypow Motors Parramatta. Is it a coincidence?
Here is a photo of said bike

You can add my BS 50 sport to your list, the frame serial number is 13A029371
Which should make it a '66 even though it's titled 1970 (the year of sale or reconstructed title)
-
Your 50 Sport serial is now added to the list - Many thanks.

Ray k can you remember the first year that the 175 came to oz as it turns out my serial number is 16d07020 which is 1966 i know that this bike was last registered in Queensland in 1976 so it has to be an original oz import? if was 1966 that bs started importation this bike would have to be one of the first to arrive here.
p.s
thanks Graham your numbers are fantastic cheers.

Coxy
I know that there were 50s and 90s imported into Victoria from 1966, as for 175s ???
In NSW I think the first imports of BS bikes were by McCulloch in 1967. However, I stand to be corrected on this if anyone else knows.

Hello, Here is another number to ad.
12 D 001650 rivet plate BS 90
12 D 001646 engine number
KD 002592 number on frame behind gas tank
I am new...feel free to look at my pics provided on my post.
I suppose my bike is April 64 what about the date?
Thanks

I have a GTR to add to the lists. It is titled as a '68 and the tag puts it at a September of '67 build, so I guess that fits.

I have a 1970 BS-100 tmx, tmx Ec 1-010064 is stamped on the steering neck and ,the Serial # on the engine is 20E015641, and on the metal tag for the bike is 22E015641
-
Hi, Thumper,
Thanks for adding your bikes serial numbers - but I think there could be problem. The engine number looks good - it fits into the BS100 Sport numbering sequence quite nicely (all BS100 engines used the 100 Sport's "20" prefix). The metal tag serail number of "23E015641", though, is way ot of sequence. The "015641" bit is the sme as the engine number. Since Bridgestones never had matching numbers on frames, engines and Serial tags I suspect that you have mistyped the tag number. I think there were only around 12,500 pipe framed BS100s made, and a May 1970 bikewould be expected to have an engine number in the region of "22E009500" - could you double check?
Graham

I have what I believe is a 90, but I am unable to find a matching vin in the table. on the frame, it is stamped 3T021285. there is also a number on the steering column 3035783. any ideas?

I have one here that seems a little out of sequence on the VIN record chart. It's a 90M Surf Rider with the following numbers; VIN: 12O039026 / Motor:12O039203 / Frame: KK040117. I'm puzzled because the VIN actually falls numerically after one listed as being produced in the following month, (12P038261). Any guesses? It's a blue 90M with a Surf Rider badge on the tank, and also noted on the VIN plate. Be glad to send a pic of the VIN plate for verification if you need it prior to adding to the list. Thanks.

Hey, Kerry,
You seem to have been reading the list properly! That;';s certainly a bit weird (the list that is, not the fact that you are reading it!?).
As your numbers are taken straight from a bike plate, I'm inclined to believe them. What I reckon has happened is that the number in my listing is a mistake for "12P039261". Either a dose of "finger trouble" when I typed it up originally, or the owner misread the number when he passed it to me.
By now I've lost track of where all the serials came from so I've got no way of confirming that, but that solution would put your serial right in the sequence, so I'll go with that and correct the listing to match.
Well spotted, sir - have yourself a beer!

Graham;
Thanks so much. Just a note; you'll have to check that errant finger. I see the VIN is entered as "12O039023"; should be "026". No worries, and again my thanks for all your hard work. Moonpup listed a Craigslist find yesterday that is only 30 miles from my home. A '70 Mach II RS, in apparently nice shape. Going over today to inspect. I'll grab numbers while I'm there if I don't buy it on site.
Cheers,
Kerry

Graham;
Today I purchased a bike that Moonpup found on CraigsList and gratiously posted for the community in classifieds. Just so happened it was only 30 miles from my house. It's a BS 200 Mach II RS, and is in terrific shape. I'll post pictures later. Let's add the VIN number to the list please. It reads as follows: 23I 00180, making it an early 200. This proofs, because the frame and engine numbers are both TA1. (frame; TA1 31002, / eng; TA1 00224). The previous owners found it in a barn, well preserved several years ago. They titled it, guessing the year as 1970, so I have some title reconciling to do with the State. Fortunately, your work with this VIN list will provide me the proof that it is actually a 1969, (built Sept. of '68). This bike has the original seat, tank, etc., all in relatively good shape. An exciting survivor find. Motor is solid, needing only carb work, as known right now.
Cheers,
Kerry
-
Will do, Kerry,
Good luck with your 200.
As for the finger, I washed my hands yesterday morning, and couldn't do a thing with them all day. (or was that my hair???)
Graham
PS.
I've just checked you 200's serial and it sits in the middle of the two serials I already have for Sept '68, so doesn't add anything extra to the listing - but it does help to confirm that the other two numbers are correct!
-
Graham, here are a few 90s to add to the list:
BS-90/T (3/1965)
tag 12O038227, engine 12O038375, frame KK039477
BS-90/M (4/1965)
tag 12P040964, engine 12P040950, frame KK041412
BS-90/SP(OI) (4/1966)
tag 18D003351, engine 18D003410, frame KC011555
BS-90/SP(OI) (5/1966)
tag 18E005128, engine 18E005174, frame KD016025
Thanks again for all the info! Steve

Hows does this apply to a rockford taka, if at all ?
Only id is on tag riveted to frame near rear shock
Model 34501
Id 14274
Most obvious guess is that its a 1974 (perhaps feb 14, valentines day bike ?)
Any thoughts ?
-
Brad;...Might be speaking out of turn here, but after BS sold off the rights to Tailung in Taiwan in 71-ish, I'm guessing that was the end of the BS VIN number trail. I doubt that BS Tailung continued the same format. Basically, they built bikes with many of the parts purchased in the deal, until Rockford folded it up in 1975. Sounds as though you may have one of the last imported units. I'm sure Richard can be of service in giving you the history, and a clearer picture, as he was involved in the operation when it was still vibrant. Good luck with the Taka. BTW... spent a few years growing up in a suburb of Detroit, called Farmington. One of the guys who played for the Lions lived a couple of houses down. That was like '63-'65. Welcome to the BS community. Great folks here.

Graham;
One of the new members inquired about their recent 200 SS purchase, and I see the serial number would fill in a spot on the ID list. #23N06123, benchmarking a Feb. '71 entry.

Good Day, Graham!
I have a new entry for you in The 350GTR VIN listings. Just purchased a 350GTR while on Holiday in Iowa. The VIN reads 21U03983, superceding the existing end number for Sept. 1967 production, currently listed as 03940. This particular bike is bearing a frame number of NA1-04007. Remarkably close. I have not gotten to the engine number yet. The bike is currently titled as a 1969, which I will get changed to reflect the proper 1968 model year.
Hope this finds you well,
Kerry Pagenkopf

Cheers for that, Kerry - I've just updated the listing to include your GTR.

Hi, I joined a few weeks ago when I first got my 350 GTR. Frame no is NA1-00284 but i've now found the plate at the back of the frame and its clearly 21000271 which doesn't seem to fit in. Engine no is 240. Am I reading it correctly?
Jonathan
-
Hi, Jon,
Yes, that seems a bit weird. The number set (...240, ...284 and ...270) seem consistent are close enough to be the original frame and engine.
I agree, though, that the "210" prefix on the plate doesn't tally. "21R" sounds much more likely and I wonder if you've misread the lettering on the plate. Is it damaged and scratched, as that can make the stamping hard to read?
Graham
-
Hi Graham,
Hopefully picture of ID plate attached.
Jonathan
-
Ah, looking at the blown up picture on here it looks like 21Q - May 67?
-
Still a glitch here somewhere. If the 21R00244 on the list is valid, your bike would have been produced a month before, but 27 units later in the production sequence. Doesn't add up, and your vin tag certainly appears to authenticate.......Graham????? any ideas.
-
We need Bikenstein to tell us what his vin is. He's said in the past that it's number 108, but I can't find the complete number. I'm betting now that it's 21Qxxxxxx.
Also, maybe Graham didn't get the complete vin for #244 and (sorry) assumed it was an "R" date?
-
Graham; Hope this finds you well;
I have a some new serial numbers to report, and one is rather exciting, at least for me. Purchased a couple of 100's for parts. One of them is a 100 trail-OI with the VIN plate of 22C-000055. Frame number is 000058. This would validate March production. The engine is a 20C number which bothered me initially until I read other comments you had posted about those being correct. Please add it to the list. The other bike is a '71 TMX, with VIN # 22N013134. As we have no starting number for that months production currently, would you kindly add it to the list also. The 3rd bike in the lot was a '66 DT175. It's VIN is 16K19968, which is later than the current number shown as last produced for the Nov. '66 production. Would you also add that in. Thanks so much for all you do in helping keep these archives alive. Your work is invaluable to us all.

Steve;
Thank you kindly for your response. I feel terrible now, not having kept up on things here. I have posted a condolence to his passing, which will certainly leave a huge void in many lives.
