Here is the 75cc Racing cylinder headless kit the most efficient in bi-segment from ITALKIT, aluminum cylinder, 6 transfers, diagrams revised upwards, very high-end . The piston is a two-segment model to once again preserve torque and strength. This piston has an opening on the back for improved sweeping and side grease nipples! The segments delivered with the kit are very fine special steels to allow high speeds.
With this kit we recommend at least: Ø19mm carburetion (24 / 25mm for good use), racing exhaust, cold spark plug (B9 / B10 depending on temperature), reinforced crankshaft and bearings.
As an option we offer a stage 1 preparation, this preparation is a modification of the channels and the exhaust port by increasing the diagrams and improving the duct, it increases the performance of the cylinder. An improvement to the piston and the bottom of the skirt is also included in this modification. Allow a little extra time for this preparation!
