A complete aluminum kit, with an optimized high-compression cylinder head in 47.6mm diameter.
Warning, top end of engine reserved for competition on circuit, closed road.
Finally available from us, here is the BRK top-end kit for DERBI VARIANT START, START 5... With some modifications, it can also be fitted to BYE BIKE or PEUGEOT 103 mopeds! Featuring a booster exhaust, 6 intake ports, a single piston ring, and a high-compression cylinder head mounted with an O-ring, this is clearly a racing top-end kit! Very similar to the METRAKIT but with a different cylinder head. The cylinder head is mounted with an aluminum gasket. The piston is not graphite-coated. This is an excellent base for engine tuning! Pair it with a good exhaust, a carburetor of at least 19mm, and an exhaust system that can handle high RPMs...
As an option, we offer a Stage 1 preparation. This preparation involves modifying the exhaust port by increasing the port timing and improving the flow, thus increasing cylinder performance. Skirt modifications are also included in this service. Please allow a little extra time for this preparation.
These engines can also be fitted to BYE BYKE or PEUGEOT 103 with an adaptation!
