The GYTR?? High Performance Kit for the YZ85 was developed in cooperation with YAMAHA RACING in Europe. It is a result of their top-level knowledge combined with their GP 2-stroke racing experience. The target of this kit is to improve the performance of the production YZ85.
Attention has been paid to reach a high performance level without forgetting the engine durability on heavy racetrack conditions as we have in Europe. GYTR Engineering developed a whole new Cylinder and cylinder head together with NEW GYTR titanium exhaust power valves to gain even more power and improves engine temperature control.
