Overview

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.
