All design solutions on the uncompromising MXV 450 have been dictated by the need to achieve the highest possible level of performance while extending the bikes range of use. The under-seat exhaust, for example, features a brand new path for better motocross performance with more torque at lower revolutions.
Valve gear based on a single overhead cam and four titanium valves per cylinder gives the best possible compromise between compactness, light weight, and performance. Thanks to its advanced technology the 45.2 engine is extremely civilized and silent running even in this motocross version, and complies easily with FIM rules for noise emissions (94 decibel threshold).
The MXV 450 affords beautifully easy access for maintenance (plugs, oil filter, air filter), and boasts extended maintenance intervals, far above the average.
The engine has a dry sump lubrication system with the oil tank integrated inside the crankcase. Elimination of the external oil tank and its connecting pipes has led to a further reduction in weight.
The starter motor has been eliminated for the same reason. Starting is by kick-start only in order to minimize weight.
