1967 BSA A65 LIGHTNING
1967 BSA A65 LIGHTNING
The 650 Lightning was BSA’s top-line bike, and meant to do battle with the market-dominating Triumph Bonneville and had twin carbs just like the Bonnie. The Lightning was certainly fast enough and handled well. It just never had the styling to compete with the Triumph. By this time, 1967, the A65 was well-developed.
1967 BSA A65 SPITFIRE MkIII
A65 SPITFIRE SPECIAL
This was the hot rod version of the A65, just behind the A65 Lightning. Like the Lightning, the Spitfire had twin Amal carbs, the first year for the new Concentric design, replacing the Amal Monobloc across the entire model line.
1966 BSA A65 HORNET
A65 HORNET
If the Lightning was at the top of BSA’s 650 food chain, then the Hornet was somewhere near the bottom. Not a bad bike, but meant to appeal to more of the commuter than the sport bike enthusiast. It had a single carb and milder cams.

This is complete un accurate, mix and mash of different models with data which is inaccurate as well. Hornet was a factory dessert racer, highly strung, no lights, open exhaust. These engines, with comp ratio of 9 : 1 had bigger horsepower than 38 BHP, from 67 they had racing cams, different front brakes ( DLS ) and Concentric carbs from 68.
