Overview

O.S. SPEED R2104 is a factory-tuned engine solely developed for 1/8 racing competition. The new engine boasts 9-port piston liner to improve torque in the low-middle power range. It produces enough power as designed even in high traction tracks. The redesigned crankshaft counterweight enables smooth power transition from low to top. The distance of each fin of the heat sink head is enhanced for better airflow for cooling and better balance.
