Malossi MHR Team by Ross 70cc Manufacture from materials of any heading, except that of the product

Flit_Latn Big Bore cylinder by tuning expert Malossi: Malossi Cylinder Kit by MHR Team 70cc for Minarelli horizontal (Yamaha Aerox / MBK Nitro), the one with the red head (cylinder head cover).

The Rossa is based on the MHR Team II, with 7 transfer ports, 1-ring piston and divided (bridged) exhaust port. One of its strong points is the exhaust port design with thin bridge and large exhaust surface. The cylinder head is divided (modular) and is topped by the eye-catching anodized red cylinder head cover.

Unlike the flange-mount version which is onlyibleible with Malossi'this version is mounted via stud bolts and can be used with standard engines and cases (as well as with the C-One. There's some milling to be done, however; the instructions are in the manual.

In raw numbers, the Rossa is quite the beast - 22hp without any modifications. It needs a matching set-up, though - high-end exhaust, racing ignition, large carburetor (28mm) etc.
