In the aluminum sport category we offer this MALOSSI MHR replica kit Ø50mm 80cc. This cylinder is the replica of the great MALOSSI MHR team! This model is certainly slightly less powerful but above all more torquey and solid! Sold without cylinder head.
The cylinder is like the MALOSSI MHR team, a diameter of 50mm which offers 76.57cc of displacement. It preserves the shape of the original base, the transfers are 5 in number and they are relatively well worked (front angle under the exhaust for better sweeping and more performance). The transfer channels are very studied, they do not require any preparation.
The exhaust is a model with boosters in order to preserve good solidity while opening the exhaust to the maximum in width. In order to slow down the race for more solidity, MALOSSI put a single segment piston, this segments is a high-end hard chrome domed 0.8mm model for less friction. Like all MHR pistons, the piston is a very high-end model, it has side grease nipples, it has a very high silicon content ...
To conclude, this kit is an extremely powerful model but above all very solid especially with the treatment and the MALOSSI MHR bore which are of the most upscale in the world! Whether for endurance, the stunt ... this kit will not disappoint! Ultra torquey, it also preserves very good high speeds!
