The MALOSSI MHR replica 70cc kit is a kit based between very high performance and maximum strength. This kit has a 47mm bore and is in nykasil treated aluminum, this nykasil from Malossi is the strongest on the market, hence the reputation of the aluminum cylinder of this great Italian brand.
Designed for the track and 70cc trophies, it is less sharp than an MHR but more torque, lovers of stunt and torque will be delighted. MALOSSI in order to solidify this kit placed 2 hard chrome domed segments against 1 on the MHR, this action slows down the race and high speeds while amplifying the torque, MALOSSI announces 7.35nm (0.75kgm) at 8000 revolutions minutes (rpm ) by malossi.
The cylinder has a modified and completely revised intake, a large normal exhaust, the diagrams are quite high and sharp, the bore is perfect and worthy of the largest cylinders, MALOSSI announces 9 CV at 8,500 rpm maximum on this kit , you can expect more or less depending on your configurations and settings. The piston is prepared (adapted) as it should to the cylinder, it is a luxury model with high silicon content. The cylinder head is in high compression (compression ratio of 13.8: 1), the chamber is hemispherical in shape we will regret a micro-blasting in the combustion chamber, we would have preferred a polishing, this cylinder head is mounted on an O-ring for more security.
In short, this kit is a small weapon of torque which does not neglect high speeds, it is very powerful but does not neglect solidity either, its degree of study and finish is very thorough. We recommend it for riding every day (except France), for competition which requires solid engines, for the stunt,… It is obviously delivered with a needle cage reinforced with a 10mm axis and a strip of KARBONIT (black fiber) to regulate the admission is to increase performance.
We advise to accompany this kit at the MINIMUM : adapted racing exhaust, complete 19mm carburetion kit, reinforced bearing kit C3 or C4 set, reinforced crankshaft, cold racing spark plug

As an option we offer 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!
