1970 BSA 650 Thunderbolt - cool bike in great shape - $8495

1970 BSA Thunderbolt 650 A65T - This BSA classic is in great shape, very original and complete.

Last year of this classic series, considered by many to be one of the most collectable BSA models. In 1971 BSA went to the unloved and unsound oil-in-frame designs, then the company folded in 1973.

This 1970 model is seen by many as the last "good" BSA ... all the detail improvements and fixes, none of the failed "modernizations". 

Thunderbolt features an easy to tune single carb head, starts readily and runs strong.

Unit construction with 4-speed gearbox. 

No issues, no problems, everything works.

Classic Brit sound and handling .. very fun bike to ride. 

Coming out of a private collection ... this bike is a beauty.

Dynamic style and flash .. all there, very original.

One of the last BSA model years to feature the chrome tank and large BSA star badges.

Comfortable dual saddle and mid-rise bars.

Clean California title current reg 

Low original milage = under 9K miles.

Starts easy, runs and rides excellent .. collection quality cosmetics. 

Great looking, nice riding, no problems classic that is ready to enjoy or add to a Brit bike collection.

Priced at $8495 or best reasonable offer ...

MODEL BACKGROUND :

BSA introduced their unit-construction 650 parallel twin in 1962. The 654cc machine started life as the A65 Star basic model, with various offshoots developing through the decade. The Lightning versions sported twin carbs, as did the highly-strung Spitfire which was intended for competition use. The single-carb Thunderbolt fulfilled more of an everyday, touring role, and by 1968 it sported 12-Volt electrics, a Concentric carb, two-way fork damping and a three-spring clutch to go with its four-speed gearbox.

The 75mm by 64mm motor typically ran 9:1 compression to produce 42bhp at 6800rpm. Fully fueled with four gallons of gas the bike weighed nearly 400 lb, so its top speed was slightly less than the 100mph mark, with a standing quarter taking 15.5 seconds or so. In 1968, the Thunderbolt would go from zero to 60mph in 7.4 seconds. The twin-carb Lightning of the same year was only marginally quicker - 15.29 seconds to cover a standing quarter mile and with a 102mph top velocity - for all that, it claimed to house an extra half dozen horses

The BSA range underwent a major (and not universally appreciated) revamp for 1971, so the final years of the previous decade are considered by many to be the easiest to live with and most desirable unit construction machines. Although not the most glamorous of the BSA 650 models, the A65T is a popular choice for modern classic bike fans

  • Hi Tedious ... We would be Ok with a sale at $6975 if that can work for you. Does not seem to be a way to lower our reserve to that on the site and we were at a higher figure. Time for this bike to get ridden and enjoyed, so we'd like to make that happen. If you can do $6975 ... it's yours .. Call me to discuss details etc.. thanks, Dean 415 601-2118
  • Tedious ... thanks for your bid .... not quite a deal yet. If you can get closer to our reserve we will try to work it out. The BSA is really a solid bike and a desirable model and year.
  • Thanks for the bid ,,, Motoauct corrected the typo... the bike is both very nice and a rare model year, so our reserve is quite a bit higher. If you can stretch for it, you won't be disappointed in the bike's condition.
