It has had a full restoration, using all genuine new parts. The list is to long, so if interested give me a call. These bikes were the first real production road racer built by Yamaha. They quickly become the bike to have if you wanted to win at road racing.. Many big names made their mark on the track racing them.This is not a replica, but the real deal, all future TZ's were based of this model. For the collector, or classic racer. Matching numbers. Eng# R3-900225, makes it #124 in the production line of these bikes.
