Ideal for increasing its performance while respecting its legal capacity of 50cc and with maximum reliability, here is the cylinder - piston kit with cylinder head stud for 50cc DERBI euro 3 and 4 motorcycle engines. The cast iron cylinder with a good finish has diagrams reviewed and corrected, like the original, it has 5 intake transfers and an exhaust with boosters. The piston is mounted in two segments to preserve torque and solidity.
The cylinder head stud offers a new compression ratio for more performance! We recommend the set with a 19mm carburetor and a sport exhaust! Use only on SP98. You will need to use the original cylinder head cover!
