Description
Metrakit Pro Race crankcase
Metrakit now also offers a high-performance tuning crankcase for heavily tuned engines: the Metrakit Pro Race. Made from high-strength cast aluminium, it provides enhanced durability and performance-oriented technical features.
It is based on the original Derbi Euro 3/4 design, perfect for tuners and racers aiming to unlock the full potential of their engine (up to 40 hp). The case can of course also be used for everyday riding.
Note: For use with FL components, you should go for the Metrakit Hyper Pro crankcase.
