Latest listing and there are many more bikes.
Would be interesting to know who had all these bikes in storage for decades.

That's a pretty one.

If it's real (always something to be checked) this would probably be a good opportunity for someone who always wanted one to get one.

If I wanted it, I'd send the money to Shane or someone nearer hand, get them to buy it for me, and have them manage the crating and getting it onto a ship. Probably $2400 total added to the price of the bike ....

I think they're neat, but since I just ride mine and don't collect them, if I wanted a 750, I'd just convert an A65 .... Never have been motivated to come up with the premium for an A70 over an A65 ...

OK, I admit it, I'm addicted to brake fluid.

But I can stop any time I want.

I would convert one as well. For the price he is asking (if it is real) its not too bad

If it's the collection I think it is, it will take a very longggg time to get through them all, if he's not just having one of his periodic culls.

They may have only made 220 of 'em but about 500 A70 engines were fitted to various sidecar outfits in the uk
in the sixties and early seventy's. The security at beezer's was a little 'lacking' i think......... Like the abundant
supply of GP carbs locally when the spitfire was in production................... no wonder they went skint.

I knew there were a good few spare engines and crankshafts made, but didn't realise there were that many.
Wouldn't the 750 twins in the 1960s have used A10 crankshafts? The A70L was only built in 1971, so BSA probably hadn't set up to forge the crankishafts until at least 1970.

Yes, my mistake, but loads of those motors were around in the early '70's even George O'Dell had one in his Windle outfit.
The cops used to love trawling the paddocks and looking at sidecar boys engines.........
Devimead were putting together A10 cranked and Norton cranked motors as well. The Hanks brothers had those motors
out to 920cc. (I did as well 81mm pistons offset ground Norton crank etc but much later on.)

Seller refers it as a June 1972 but A70LGE01103 referes to June 1971 in my books. what do you reckon about that? And how about that high number 1103 could that be right?

I'm not saying just asking..

It would seem perhaps half as many 750 twins went out the back door than the front door?
Other than my engine (only) I've never seen an A70 in person.
I ran air cargo at JFK for about 9 years or so-1980s/90's. One evening at Aer Lingus,I happened to be wearing a BSA t shirt.
One of the old timers told me that Aer Lingus had transported BSA's over the pond, and that a few, would almost always, 'go missing'. shocked

Interestingly enough,The A70 Registry shows GE01101,at the time of posting, in Melbourne.
This list has not been updated for some time.
I have engine # HE01171
A GE prefix indicates a 6/71 production date.
There was no 'F' code prefix.Link

These bikes were titled 1972 but were made in '71. Mine was made in June and pretty close to his number. Mine is original with 13,000 miles and has been in the registry for a couple years. On the top of the RH Case, there should b a number 7 in a circle as you look down on the motor, that's the only physical thing I remember different. Not something that can easily be duplicated.

just looked at the pics again and can see the raised circle and I'm certain the 7 inside. Looks legit. My mufflers are much larger at the end, not sure if those are original?

Mine too, has a stamped 7 (July production?) in a cast in, raised circle,at about 10 o'clock, from the transmission fill point.With my limited knowledge,this particular machine also, appears to have, RE Interceptor silencers.
I also have FSA65HE11930,that does not have, the cast in, raised circle,or the stamped 7......

Hi,

Aiui, not even as early as that.

Risking telling you something you know already, the "200" numbers come from a '71-on AMA requirement for Class C racing that at least 200 of any engine or component have been made available for sale to the general public. 200-odd each of T150's and Rocket 3's with Quaife 5-speed gearboxes were built and shipped early in 1971.

Afaict, there appears to have been an initial belief that triple engines would be used in both on- and off-road races for the AMA No.1 plate; in reality, triples proved unsuitable off-road, even in special (e.g. Trackmaster) frames, and Triumph and BSA riders reverted to twins. However, both T120 and A65 were 100 cc. and one gear down on particularly the XR750; the 200-odd A70's and a similar number of 5-speed T120's built at Meriden also in June 1971 seem to have been a rush-job to homologate something more competitive for the US Triumph and BSA riders?

Just a thought but were they truly "A70"? Aiui, the A10 stroke is only 1 mm. different? And within - what? - less than a year of the first A70's, BSA motorcycle production had pretty-much ceased?

Originally Posted by Morgan aka Admin

As I understand it, the A70's were numbered in the '71 A65 range.

Finally here, the Fleabay ad. says, "This bike is in original untouched condition"; red tank and chromed(?) sidepanels seem to belie that?

Hth.

Regards,

Keane, from what I've been told, the 7 stands for 750 because of the stroker crank and would not be on any other bike. For some reason, maybe a bearing or special machining, that rh case was different.

The machining for the timing side main bush and shim pack is different.
I've been told that the internal machining is slightly different as well to allow extra clearance for the con rods.

Yes it is the collection with around 1000 motorcycles and a deceased estate.

These are auctions so the highest bidder wins, sniper or not.
If you want a bike you take the risk and bid accordingly, not to mention these are seen online by the world so they (the auctions) are hardly going to be a secret or not seen. facepalm

To have won this A70 you would have needed a bid of around $16000 +, remembering the sold price on this one was in the lower end for most Commando's or Triumphs here, low enough to be in Moto Guzzi Loop prices.

An auction sniper won't do you any good with something like this. As has been mentioned, the whole world knows that an A70 is up on offer; you're not going to be one of 5 people looking at it, and the other 4 don't know what it's worth.

You know what your maximum bid is; just put it in, and eBay will put your bid in AHEAD of the sniping programs .....
