High motor kit ATHENA RACING special race 44mm, ie it can be mounted in combination with a crankshaft race 44mm ! It is therefore mounted on scooters PIAGGIO / GILERA which make 75cc of origin! Or on the 50cc with a crankshaft stroke 44mm (also available from us ). Of very good quality, the cylinder of Italian foundry is in high-end aluminum, it has a treatment of very high quality nical, the diagrams are increased to offer a lot of power while preserving a good couple! You will notice that the cylinder has fins much larger than the original 50cc cylinders for better cooling. The piston is a mono-segment to make room for high speeds with less friction and resistance!
The segment is of course chromed pre-lapped steel. It comes with a high compression yoke to offer a nice compression ratio! The kit is delivered with exhaust studs, gaskets, axle, clips, slats of carbon valves adapted to the speeds operated by this engine ... This kit with the long stroke crankshaft 44mm is a monster of torque and power! Much more powerful than all 70cc original racing kits on the market! Especially that ATHENA architecture is in the world's best on 2T engine!
Optionally we offer a stage 1 preparation, this preparation is a modification of the channels and exhaust light by increasing the diagrams and improving the pipe, it increases the performance of the cylinder. An improvement of the piston and skirt stocking is also included in this modification. Allow a little extra time for this preparation!
