I have found a 72 A70L which I hope to buy. I have some questions about the numbers. The numbers match on frame and motor. They are A70L/GEO followed by four digits. The numbers seem high considering the low production of this model.The numbers are pristeen and show no alteration. Would someone familier with these bikes help with an explanation. Is there a registry for these models? Thanks Bill

My book doesn't cover A70 models, but if they followed the same convention as A65s, the G would refer to June and the E to 1971. Perhaps the O is a zero?

I assume you mean four non-zero digits. Yes I've heard only a few hundred of these were produced; maybe they started with a high number.

Hi Bill,

Matching-numbers A70's are rocking-horse sh1t. 202 (minimum 200 required) were built by BSA to homologate the model for AMA-sanctioned off-road racing, the A75 Rocket 3 being used for 'pavement' races.

The numbers are the standard '69-on BSA format - "GE" (date code) plus five digits, the "O" is a zero. They're "high" because the batches (there were more than one) were built interspersed with A65's. A bit of time spent researching on here and the rest of the internerd should turn up whether the number you're looking at is in one the batch ranges. Also, Mick at Burton Bike Bits in GB knows a fair bit about the model and has some of the model-peculiar spares.

But I wouldn't spend too much time umm-ing and aah-ing; if the price is reasonable, someone else who's done their research already will have it away.

Hth.

Regards,
