I have the opportunity to acquire a 1965/66? A50 Cyclone rat. The bike is approximately 85% complete but VERY rough and rusty. All fibreglass parts are trash, the control cables are rusted in two, forks and rims are a solid mass of rust. Last run 1971 then parked in a carport.
Amazingly, both wheels turn and the engine kicks through and shifts to all four gears. I have a soft spot in my heart for unloved Brits; is this worth the $500 asking price? HELP!!!
If you are sure the bike is an actual cyclone ,$500 sounds like the most I would go , but I would probably grab it .They tend to be kinda rare , not sure how desirable they are though . Any title ? engine/frame numbers ? 8 fins on the cylinder barrel , twin carb head ?If this isnt a cyclone , or Hornet etc... sounds like the asking price needs a little work .-BONZO
Hi That Cyclone is a pretty rare beast. No pics in Bacons book. The motor number should be "A50 B or A50D". Twin monoblocs , sports cam, 9:1 comp, CR gearbox. Not as tuned as the later Wasps which got 10.5 to ones. Sounds like a hoot for an off road blaster. Not gonna be cheap to rebuild though. Cheerrs pod

Serial number on frame begins "A50C...", has twin AMALS, fibreglass Hornet style tank, twin upswept pipes, no silencers. It was advertised as a Hornet. Where do I look for engine numbers, please? I am unfamiliar with the BSAs. Thanks to all who posted replies so far!!!!! :p
This is sounding more like a hornet all the time . A50C was the frame designation for nearly all of the 1966 twins and for the first several years of production all 500 and 650 frames were marked starting with "A50" and it wasnt until later in the 60's that the frames were stamped the same as the engine . Not sure where you came to the conclusion it was a cyclone , other than the "A50C" probably sounding like it meant "500C"yclone? We wish the numbering ,or anything else , on these bikes was that straight forward. Anyway , the engine numbers should be on the engine case , left side , just below the cylinder base . A 500 should have 8 fins on the cylinder , a 650 should have 9 , other than that there isnt much viually different between them . A "matching numbers"(numbers dont actually match , but the serial run should put them at the same year) bike for that year should have an engine number that should be: A-50 Royal star "A50R-101" A-50 Wasp "A50W-101" A-65 T-Bolt "A65T-101" A-65 Lightning"A65L-101" A-65 Hornet "A65H-101" A-65 Spitfire MK-II "A-65S-101"
Again , I suspect it is a Hornet, if so , and you are interested in restoring it it should be worth what they are asking , but that is an offroad bike , and adding lights may take away from its value or show class
If it is a Wasp , probably more collectable , but same situation as the Hornet .
If it is a spitfire MK-II , pay the money and dont ask questions a matching numbers version of that bike is kinda sought after these days
Anything else would be a standard streetbike that may have been modified to its present condition , but doubtful. Either way , it wouldnt be very cost effective to restore , and basket in that condition robably isnt worth that $$ , even if it isnt much, there are still some decent deals outthere on BSA unit twins .
