Overview

The O.S. SPEED R2104 is a factory tuned engine solely developed for 1/8 racing competition. This new engine boasts 9-port piston liner to improve torque in low-middle power range. It also produces enough power as designed even for high traction tracks. The redesigned crankshaft counter weight enables smooth power transition from low to top. Distance of each fin of the heat sink head is enhanced for better air flow for cooling and better balance. The heat sink head is anodized in both black and red for a high contrast and powerful aesthetic.
