The MALOSSI MHR replica 70cc kit is a kit based between very high performance and maximum strength. This kit has a bore of 47mm and is in nykasil treated aluminium, this nykasil coming out of malossi is the strongest on the market, hence the reputation of the aluminum cylinders of this great Italian brand.
Designed for the track and 70cc trophies, it is less sharp than an MHR but more torquey, stunt and torque enthusiasts will be delighted. MALOSSI in order to solidify this kit has placed 2 hard chrome domed segments against 1 on the MHR, this action slows down the race and the high revs while amplifying the torque, MALOSSI announces 7.35nm (0.75kgm) at 8000 rpm ) by malossi.
The cylinder has a modified and completely revised intake, a large normal exhaust, the diagrams are quite high and pointed, the bore is perfect and worthy of the largest cylinders, MALOSSI announces 9 HP at 8500 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 be to the cylinder, it is a luxury model with a high silicon content.
The cylinder head is in high compression (compression ratio of 13.8:1), the chamber is hemispherical in shape, we regret a microbeading 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 torque weapon which does not neglect high speeds, it is very efficient but does not neglect solidity either, its degree of study and finish is very advanced. We recommend it for everyday riding (outside France), for competition which requires solid engines, for stunts, ... It is of course delivered with a reinforced needle cage with 12mm axle and a KARBONIT strip (black fiber) to regulate admission is to increase performance.
We recommend to accompany this kit at MINIMUM: adapted racing exhaust, complete 19mm carburetor kit, reinforced bearing kit C3 or C4 clearance, reinforced crankshaft, cold racing spark plug .
