Speedzone Ultra Torque spec rotor
Speedzone has introduced a new ultra-torque rotor for their spec class motor line. The 12.5×25.8 rotor is recommended for off-road and on-road use when conditions warrant even more torque than the standard high torque rotor. The rotor and shaft come marked for easy identification and it is available now.
