Cylinder / piston kit without cylinder head 75cc Ø48mm ITALKIT Racing aluminum mono-segment DERBI euro 3 & 4

Not approved, prohibited on road, reserved with the competition and closed circuits, private.

Here is the best performing 75cc Racing kit in mono-segment from ITALKIT, aluminum cylinder, 6 transfers, diagrams revised upwards, very high-end.   The piston is a single-segment model to promote high speeds. This piston has an opening on the back for improved sweeping and side grease nipples! The segments delivered with the kit are made of 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!
