BSA A50 / A65 Twins Gear Shift Quadrants & Repair Shafts (1) - Choose Part Type

Finding a good used or NOS BSA gear change / shift quadrant is very hard to find. Those that can find one will have to pay the price! For only $39.95 you can make your old quadrant line new again by replacing your damaged shaft OR you can purchase a new complete unit from us for $140..

Shafts are designed to replace your old damaged / worn out splines. (I highly recommend a machinist or machine shop to perform this work - involves cutting your original shaft off, boring, pressing the new shaft in and then welding (or brazing))

Our complete gear shit quadrants will fit most A50 and A65 unit twins (Lightning, Royal Star, Hornet, Thunderbolt, etc) from approx 1968-1972 - repair shafts are universal and can fit all A50, A65, C15, B40, B44 & B50 models as well as the Triumph "Cub"
