Description

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.

The MHR Replica Cylinder includes a single piece head, with o-ring type reusable gaskets for ease of work. The coolant outlet on the head different to the standard has a plastic fitting which secures to the head via 2 hex screws. The advantage of this fitting system apart from its ease of removal, is the coolant bleeder valve on the leading right hand edge. This makes bleeding the cooling system fast and incredibly easy.

It is highly recommended to pair this cylinder with a performance exhaust. The Stage 6 Pro Replica Exhaust is a match made in heaven with this cylinder, as its construction is specifically designed to be paired with the MHR Replica Cylinder range.
