Marchesini, Marchesini Wheels, Marchesini Forged Magnesium Wheels

Marchesini wheels forged magnesium 10 spoke wheels
New Marchesini 10 spoke forged magnesium wheels. Currently used on the WSBK bikes. Slightly lighter than the 5 spoke cast magnesium wheels.
The forged magnesium wheel is lighter and offers more stiffness. The rim is also a little lighter which reduces dynamic weight and adds to the overall performance.. The forged wheel because it is completely machined also runs very true which improves the performance of the wheel.
Marchesini wheel weights with bearings:
NEW 10 spoke forged magnesium wheels : Front: 6.04lbs, Rear: 7.76lbs
Original 5 spoke magnesium: Front - 6.80 lbs, Rear - 8.70lbs
OEM aluminum 3-spokes, 11.5 lbs front, 13 lbs rear
OEM aluminum 5-spokes (996/998), 9.25 lbs front, 12 lbs rear
Unique advantage of the Marchesini Three Dimensional Forging Process: When you forge a piece you normally come straight down and cut the part out like you would make a cookie from a cookie mould.
This process is called ""open die"" forging and is the simplest and lowest cost way of forging. You then have to machine out the well and bead area which interferes with the fiber structure of the material causing a loss of strength.
Marchesini forging process used to make the Marchesini wheels uses a precision three piece mould, ""closed"" die process which is ""more expensive and complex,"" to not only form both sides but also to form the well and bead seat of the wheel. This process makes a superior wheel with higher mechanical properties.
However, you can understand the complexity of making a three piece mould that must have side sliders operating under 15,000 ton pressures. The Marchesini forging three piece closed dies are precision, complex, and very expensive. However, you receive the benefit of this investment in technology.
The other advantage of the forged wheels is that all surfaces are ""machined"" which creates a precision wheel. The trueness of a forged wheel adds to the overall performance of the wheel.
