Ideal for refurbishing your ROTAX 125cc 2-stroke automatic KARTING engine (ROTAX MAX 2T), here is the high engine without cylinder head ITALKIT 140cc, the diameter is increased to 58mm. Cylinder manufactured at GILARDONI, VERTEX piston, delivered with gaskets, segment, piston pin, clips ... Everything is of very high quality! The cylinder is therefore an aluminum model with a well-designed architecture and channels.
With specific intake transfers really well designed and a large valve exhaust, oval / widened shape. The valve exhaust system is identical to the original, the valve is not supplied with this cylinder, it you will therefore have to take back the original part. The aluminum alloys used are excellent and will guarantee increased reliability and strength of your engine, provided they are fitted perfectly and without burrs.
This cylinder is accompanied by a top-of-the-range VERTEX piston with specific heat treatment. Its thin segment of thickness, will promote clear recoveries, the rise in speed but without neglecting the speed at high speeds for their finesse.
Thanks to the treatment, its shapes and its composition, this piston has been very well designed and studied in order to offer better thermal expansion, at the same time fitting perfectly with this cylinder to withstand frank resumes, sudden changes of regimes. and prolonged use.
Obviously delivered complete as presented, you will be as surprised as we were on this material which guarantees extreme reliability and performance largely on the go.
We recommend it with at least: a relaxation exhaust, a minimum 30mm carburetion (flat bushel will be perfect), original cylinder head.
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 exploit the good speeds. There is therefore no modification to be made to install a pneumatic valve!
As an option we offer a stage 1 preparation, this preparation is a modification of the channels (intake faults) and the exhaust port by increasing the diagram and improving the duct, it increases the performance of the cylinder. and skirt stockings is also included in this modification. Allow a little extra time for this preparation!
