Tired of that mushy feel you get when riding your BSA? Chances are your fork springs are in need of replacement.. instead of installing the OEM springs why not install some progressive fork springs? 

Progressive fork springs will give you BSA a more "modern feel". BSA progressive fork springs will change the performance and handling of your bike. Let's face it BSA had suspension that was outed when it was made, why settle for the same?

Fork springs measure approx 11" long with an outer diameter of approx 2". Fits BSA A50 and A65 unit twins (Lightning, Royal Star, Spitfire, Hornet, Wasp, Rocket, Thunderbolt, Firebird, Etc) from 1964-1970 without the "nacelle". Fits various BSA unit singles up to approx 1970. Also fits many BSA "A, B, & M" group pre-unit twins and singles. Please refer to your parts catalog for proper fitment.
