Features 5 ports, silicone-filled crankshaft, premium Japanese front and ceramic German rear bearing. The K501R is an extremely reliable and powerful engine suitable for any race track and racing conditions.

 All the finest engineering and craftsmanship has gone into the concept, design, creation, and finishing of FX Engines.
