Kit 90cc high engine Ø50.2mm MVT special race 44.8mm 13mm axis DERBI euro 3 & 4

Not approved on open road, only reserved for circuit competition, closed road.

It is a very powerful kit but designed to last in time. It is composed of a cast kit with piston bi-segment Ø50,2mm, exhaust a booster, 7 intake transfers, a high compression mono-block crease...Criticized by some, mono-block creases avoid stacked / multiplied joint problems that amplify the risk of leaks! This ass is made in an alloy that perfectly drives the heat and does its work very well. All is developed with diagrams to give an excellent ratio couple power in order to be able to ride in all conditions! The piston axis is increased to Ø13mm to avoid problems. The set is recommended with a carburation in 28mm, an exhaust well granted to this cylinder, a well released ignition like the PREMIUM MVT, a clearly reinforced clutch.

In option 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!
