This kit is no longer like the original, ITALKIT has totally optimized this cylinder in order to offer a real gain in power compared to the original while preserving excellent engine strength and reliability, a diameter of 57mm for the piston VERTEX is an increased displacement to 140cc.

The cylinder is therefore an aluminum model with a very well designed architecture and channels. With specific intake transfers really well designed and a large exhaust valve and boosters, oval / widened shape.

The valve exhaust system is identical to the original, the valve is not supplied with this cylinder, so you will have to take the original part or if possible, the ITALKIT pneumatic valve!

The aluminum alloys used are excellent and will guarantee increased reliability and solidity of your engine, as you will have understood, on condition of a perfect assembly, clean and without burrs. This cylinder is accompanied by a piston with two segments of the brand, VERTEX top of the range with specific heat treatment. Thanks to the treatment, its shapes and its composition, this piston has been very well designed and studied in order to offer a better thermal expansion, at the same time agreeing perfectly with this cylinder to withstand frank revisions, sudden changes of regimes. and prolonged use.

We recommend it with at least:

 

-A relaxation exhaust

-A carburetion at the minimum of 30mm (flat bushel will be perfect)

- ITALKIT pneumatic valve

-If your engine is prepared, or still old, we will recommend changing the crankshaft, in passing do not hesitate to install a reinforced connecting rod kit. -A set of rigid carbon valve slats will also be welcome in order to use the right speeds.

 

As an option we offer you 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!

 

This model 122 (unlike the 123) does not need any modification to the position of the valve to install a pneumatic valve! The hole is already made! In any case, on ITALKIT models, all ROTAX cylinders have the hole!

 

Mounts on:

 

125cc ROTAX 122, aprilia RS, AF1, EUROPA, PEGASO, and other 2-stroke
