I am considering the purchase of a 1972 Thunderbolt.
The vin starts with A65TJG009. I cannot find any reference on the ID Charts to anything in 1972 with a JG in the vin. The chart only refers the A65 for the frame number for a 72 Thunderbolt.


I APOLOGIZE FOR THE USE OF CAPS. I CAN ONLY TYPE WITH MY RIGHT HAND SO USING THE SHIFT KEY IS BEYOND MY CAPABILITES.

The Devil is in the details.

1957 BSA A10 Spitfire Scrambler (numbers matching, very correct, very nice condition)
1965 BSA A65 Lightning Rocket "Clubman" (restored)
1966 BSA A65 Spitfire MK-II (restored)
1967 BSA A65 West Coast Hornet (under rstoration)
2001 Kawasaki W650

A65TJG-xxxx would be a Thunderbolt (T) manufactured in August (J) of 1972 (G) according to the reference I always use, which has proved accurate in the past ....


I stopped believing for a little while this morning. Journey is really going to be upset.

Concur with Lannis. Roy Bacons BSA buyer guide shows Aug-72 build. pretty much the end of the line of 650's with a handful of A70L coming here.
keep us posted if you get it.

I would say that it is a 1972 model year Thunderbolt manufactured in August 1971.

Upon mature reflection and further research, I think you're right. The "G" indicates manufactured in the "Model Year" 1972, which is actually AD 1971.

The last A65 twin came off the BSA assembly line at Small Heath in February 1972, so August 1971 it must be.

My old heap is A65T KG01*** That's a '72, probably slung together in Brum late '71.

Your "1972" bike is most likely an early one, built in September of 1971.
There may still be some lingering 1971 features remaining on it.

Seems up to 72 par, black frame, iron oil pump, scalloped flywheel, stupid small tank and bars etc.
Doesn't have the steel capped rods though, only the last few got those.

Actually Nick there are a lot of 71 numbered A 65's sold down here as "brand new" 73, 74 or 75 models.
These were all returns from other places and in some cases had European compliance plates fitted.
These were all late 72 spec. I have one with steel capped rods, cast iron pump, etc.
The story is they were "remanufactured" remaindered bikes sent down here cause Australia is so far away we would not know that BSA has closed down.
The other story was the local agents bought the bikes cheap and then did the retro fit & respray locally.
Never had proof of the story either way. But the bikes are real I knoow of 5 of them ( including mine sold as a 73 )

All of them are painted in Norton colours over a silver base just with less coats of the translucient laqueur so they were a lighter blue, green, red or white, solid colour, black frames & guards with the extra wire brace.
Most had the large tank.
By now I would have thught you would have come across a few by now.

Hi Ken,

Don't know about every BSA model line but I do know the first '72 Rocket 3's were made on 24th August 1971, stamped with a "JG" date code.

On the same day, they also built about thirty R3 engines that'd been numbered - but not date-coded - in the '71 number range. To get the bobblies going on internet forums half-a-century later (very prescient), they date-coded these bikes "JG" too.

Hth.

Regards,

Australia was BSA's biggest export market till 1952.
We bought a lot of bikes mainly because it is Gods gift to motorcycling with about 300 dry days a year ( in Sydney ).
When the USa became BSA's main target, we got dropped so ended up being nearly a full season behind the USA.
However it ws very common to send bikes that missed the USa wes coast selling season down here where we tend to buy bikes all year round.
Thus it was not uncommon to see USA west coast brand new bikes in Australian showrooms before the UK & general export versions arrived.
Almost as common to see both side by side in showrooms.

I was told but can not confirm that BSA's were still being sold in India brand new as late as 1984

Yes, i wondered what would have happened to all the stock that was held worldwide and how the dealers were left contractually, when beezer shut.
Going by some notes on here, beezer must have owed lots of money on warranty claims and dealers would have had to work on the remaining stock
if they were going to sell it with any warranty at all. I know a couple of dealers in London still had A65's in their showrooms well after the event. (Slocombe's + Kays)

August 1971 manufactured 1972 MY.
I read somewhere that the last batch of A65 twins were built on 10th of December 1971, of course it could have been February '72 instead, but I think that by August '72 the BSA twins were sadly consigned to history.

There has been a lot of confusion caused over the years by people stamping frames and engines with "impossible" number combinations (and it's still going on now)

Very recently a large bike breakers near me sold an imported T120V frame which had a number that could not possibly have been issued by the factory.
The breakers had made a NOVA declaration on that frame number too.
Now someone has bought it and will no doubt be applying to the TOMCC for a dating certificate.
Well I think that they will be in for a nasty surprise
