Description
Malossi Clutch Bell Maxi Wing d.150mm Yamaha X-Max 300cc E4.
Malossi's famous "Wing Bell" is forged from high-quality steel (39NiCrMo5), with an anti-oxidant nitrogen-treated hardened surface. It is without any doubt one of the best clutch bells on the market, with reinforced fins (wings) and large cut-outs ensuring adequate cooling.
The HQ clutch bell provides excellent grip even with hot engines and at high rpms, so power transmission is improved. Finned sidewalls provide additional stability and optimal cooling, basically the same cooling principle as in air-cooled cylinders. Large cut-outs add the the cool-down effect.
Suitable for all kinds of engine set-ups, from original to high-end.
The function of the clutch bell
Even though the clutch bells of scooters (centrifugal clutch) and clutch baskets of motorcycles (with multi-plate clutch) look different, their function is basically the same. What changes is the way they are actuated.
On a scooter or moped with a centrifugal clutch, when the engine revs up, the clutch shoes spread and engage the clutch bell and cause it to rotate. The bell then drives the transmission, which in turn turns the wheel.
On a motorcycle or motocross bike with a multi-plate oil bath clutch, the lined clutch plates engage the plain metal plates, which in turn drive the bell to rotate the transmission and wheel. When the clutch is actuated, the lined discs no longer engage the plain discs and rotation comes to a halt.
In short, the bell ensures that rotation is transferred from the engine to the gearbox and wheel.
Clutch bell: performance
With a tuning clutch bell, it is possible to improve performance or reliability.
Choosing materials like steel instead of aluminum provides greater durability. The heavier weight of steel also leads to higher inertia, which in turn can lead to higher torque. This is the case with the Hinson Momentum bell, for example.
A bell can also have cut-outs to improve cooling and thus prevent wear. Therefore, on scooters, you often find ventilated racing clutch bells. Also in motocross, some clutch bells have more cut-outs than others.
In summary, the weight and ventilation of a clutch bell affect the overall performance of the engine.
