The CR21 features a newly designed crankshaft to improve engine response and a lightweight piston that further assists with a crisp engine response on throttle input. The combustion chamber design optimizes low to medium RPM ranges, perfect for newer racers, while still offering high performance output at high speeds for more experienced drivers. And it is easy to tune and stabilize with a 2-needle carburetor with 6mm and 7mm inserts available.
