After an accident
at Lydden in 2000
The following is a basic list of the items used in the engine and transmission, and the chassis of the open class Trident owned and ridden (and crashed!) by Philip Pick in the 2000 season. This motorcycle is currently under repair and will be used again in 2001. It is expected that Alan Walsh will be the main rider in 'unlimited' class events. It is based on a 'production' chassis, and was last used as a production specification bike by Simon Walsh in 1998.
