Unapproved cylinder that does not respect 125cc cylinder capacity.
Here is the complete 140cc cylinder/piston kit from the great brand ITALKIT Engine competition 125cc 2 Time ROTAX 123, aprilia RS, AF1, EUROPA, PEGASO, ... and other models.
This kit is no longer the origin, ITALKIT fully optimised this cylinder in order to offer a real power gain in comparison to the original while preserving excellent engine strength and reliability, a diameter of 57mm for the VERTEX piston or a cylinder increased to 140cc.
The cylinder is therefore an aluminum model with very well designed architecture and channels. Featuring truly well designed specific intake transfers and a large valve and booster exhaust, ovalized/extended.
The valve exhaust system is the same as originally, the valve is not supplied with this cylinder, so you will have to take back the original part but we strongly recommend the use of the valve ITALKIT tyre.
The aluminum alloys used are excellent and will guarantee an increased reliability and strength of your engine you will have understood, provided of a perfect mounting, clean and without blush.
This cylinder is accompanied by a piston of the brand, VERTEX high-end with specific heat treatment.
Thanks to the treatment, its forms and its composition, this piston was very well designed and designed to offer a better thermal expansion.
At the same time, it fits perfectly with this cylinder to withstand straight covers, brutal changes in diets and prolonged use.
We recommend it with at least:
a relaxing escapement, a carburation to a minimum of 30mm (flat bush will suit perfectly). Valve if possible ITALKIT tyre. If your engine is ready, or old, we will recommend changing the crankshaft, by the way do not hesitate to place a reinforced rod kit. A set of rigid carbon valve slats will also be the good one to exploit the right diets.
Optionally we offer you an internship preparation 1, this preparation is a modification of the channels and exhaust light by increasing the diagrams and improving the duct, it increases the performance of the cylinder. An improvement in the piston and skirt stock is also included in this modification. Count an extra time for this preparation!
