Product Info  

For 30 years the Yamaha TZ has been involved in the history and tradition of GP Road Racing, taking advantage of feedback and knowledge gained through the factory race programs. This evolution continues, building the glory of the TZ line.

The TZ250 was the championship machine in the 2001 All Japan Championships, and in the 2002 All Japan series it swept the top four places in each of the first five rounds of the season. This kind of consistent competitiveness has won the TZ250 the trust of riders in the Japanese market.

The 2003 model TZ250 adopts various technologies from the MotoGP factory machine YZR250 in the form of numerous spec changes in the engine and chassis to achieve an extremely high level of competitiveness. The competitive potential it achieves makes this model worthy of being called a YZR250 replica.
