Marchesini M7 Genesi are the best performing forged sportbike motorcycle wheels available. A product of Marchesini's deep experience in the world of racing, the M7R Genesi has been developed using cutting edge design, structural analysis and development techniques. The use of alloy normally used in aerospace applications, multi-directional forging and the use of dies optimized for final wheel geometry have helped to create an extremely lightweight material with excellent mechanical properties. Compared to OEM wheels, the 7-spoke Magnesium M7R can be lighter by 25-45% and the 7-spoke Aluminum can be lighter by 15-35%. For every ounce in static weight reduction on the rim, the equivalence dynamically (while in motion) is significant (about 12.5 lbs of weight at 50mph, 24 lbs at 100mph and 36 lbs at 150mph) enabling your suspension to hold the tire against the asphalt better with greater acceleration. An anti-slip paint finish applied to the wheel rim is instrumental in preventing relative movement of the tire and rim when accelerating and braking and, consequently, improving the feeling of the ride. The cross section and contours of the spokes are designed to optimize stiffness and thermo-fluid dynamic efficiency in operation. This is a product that makes no compromises, aiming quite simply to be the highest performance wheel ever fitted to a sport bike. A product that leaves the competition far behind and is guaranteed to outperform any other in terms of shorter stopping distances, sharper acceleration, and faster, more precise cornering.
