The MotoSport.com Marchesini Rock Complete Wheel Combo includes ONE Front and ONE Rear Marchesini Rock Wheel, each with the following features:
Marchesini has now used its experience and know-how in off-road racing. The new Rock wheels are specially designed for motocross racing, and have been developed with a strong technical content that enhances and updates the architecture of traditional spoked wheels.
Dispensing with the nipple connecting the spoke to the rim, Rock wheels offer a significant reduction in weight in the outer circumference: This is an important technological innovation and one that can be seen and felt immediately in the motorcycle's high levels of responsiveness.
The hub is machined from a solid block and the spokes are straight and much more resistant: consequently, the number has been reduced from 36 to 32. That's not all - thanks to the new set-screw locking mechanism that allows perfect rim-spoke coupling, spoke alignment is no longer necessary on the new Marchesini Rock racing wheels.
Enthusiasts have no need to worry - there are Marchesini wheels for off-road racing, too.
General Technical Advantages:
- Higher resistance to the three traditional wheel stresses:
- 1. Radial: Impact and jumps.
- 2. Lateral: Directional changes.
- 3. Torsional: Braking and acceleration.
- Weight reduction:
- No spoke nipples.
- Extremely lightweight hub.
- Reduced number of spokes.
- Cleaning:
- No dust deposits around spoke nipples as with traditional spoked wheels.
Rim Technical Advantages:
- Marchesini "Rock" wheels use D.I.D. Dirt Star rims.
- Five axis machining technology.
- Spoke design eliminates the traditional punched spoke holes - this significantly reduces rim machining times with consequential increase in rim profileprecision.
- The rims have clean cut spoke holes giving a more precise machined finish to the rims and reducing overall wheel weight and consequential inertia.
- Precise alignment of the spokes with the rim inner surface.
- Every Rock wheel rim is identical across all model applications.
Note:
Wheels ship with complete instructions. The spoke torque wrench (P/N 20-6-FST100) is sold separately. Wheel spokes should be torqued to 4.5 Nm.
