The Malossi MHR Rep kit has increased port sizes, and Malossi’s 9 port design which features 2 extra ‘booster’ exhaust ports to greatly increase the flow of exhaust gasses from the cylinder. The MHR Replica also features a full alloy construction with a Nikasil bore, which is virtually indestructible. What makes this cylinder so unique is the pairing of its twin ring piston in a Nikasil bore. Against single ring (race orientated) setups the MHR rep is far more ideal for street use being more reliable and less all out aggression.
It is recommended HIGHLY that this kit is accompanied by a performance exhaust.
