transmission gear up kit Top Racing +18% for Kymco AC

Pre-pressed racing transmission with a gear ratio of 18% higher. A must have for tuned engines to generate a higher speed. Power alone is not enough. If the engine has power and the transmission is too short, the engine breaks. The Top Racing transmission is already pre-pressed. So out with the old and the put in the new. Recommended only for tuned engines. Note: Tuning transmissions usually feature straight teeth. This leads to less friction but also to a higher noise level. This is completely harmless.
