The TC 85 engine uses the latest in 2-stroke technology to deliver unrivalled performance in the competitive 85cc class. With an unchanged bore and stroke, the engine is1.5 pounds lighter and delivers improved power and ride-ability along the complete RPM range.
The cylinder is designed around an innovative power valve system, the system controls both the exhaust valve and the sub-exhaust port for impressive power, torque and controllability. As a result, the TC 85 delivers significant mid-range performance, reducing the need to use the clutch in loamy or sandy conditions.
Manufactured using a high pressure die-cast production process, the crankcases are designed with thinner wall thickness to save weight, while retaining strength and durability. This design also aids in a more compact arrangement, positioning the shaft arrangements closer to the center of gravity for improved handling.
The TC 85 features an upgraded diaphragm spring clutch for improved durability while remaining lightweight and compact. The clutch is actuated using a FORMULA hydraulic system, meaning that play is always compensated and the clutch point remains the same under different conditions as well as over time.
