The following is a basic list of the items used in the engine and transmission, and the chassis of the production Trident owned and ridden by Alan Walsh in the 1993 season. This motorcycle has been substantially unchanged since then and is now ready for races in 2001. Recently Alan and I were in conversation and we decided that very little was left of this bike from its original form. Alan bought a road specification in 1970 and raced it. It was given a 'Works' short frame in 1972 and of that specification bike only the following components are still in use:
Gearbox Outer Cover, Rocker Boxes and Internals, Pushrods, Inlet Rocker Lid, Carb Lift Gantry and Cam Timing Gears.
'Works' Frame, Subframe and Swinging Arm, Electrics Plate, Engine Plates, Rear Brake Pedal, Rear Wheel Hub, Rear Brake Plate, Rear Mudguard (perhaps).
