The Testa Rossa is based on the MHR Team II, with 7 transfer ports, 1-ring piston and divided exhaust port. And Malossi came up with a very interesting and ingenious way of mounting the kit: a ‘flange mount’ that clears the exhaust passage and opens up more options for tuning / modifications / porting. Another strong point is the modified exhaust port design – a thin bridge, large exhaust surface. The cylinder head is divided (modular) and is topped by the eye-catching anodized red cylinder head cover. 70cc displacement and power galore – it can’t get much better.

Because of the different mounting system the kit can only be mounted on Malossi C-One or RC-One crankcases. The flange is included and allows for mounting the cylinder without any bolts cutting through the cylinder.
