Description
Maxi Belt from Polini
The Polini Original Belt is the perfect replacement for the original belt if you want to replace it with a stronger one. Thanks to the high-quality materials, it is very durable and temperature-resistant and can also be used for tuned setups without any problems. Good grip, low abrasion, long service life, no slipping - top drive belts for everyday use.
Important: The V-belt should always fit exactly. Belts that are too narrow and therefore sit too low reduce the top speed, belts that are too wide and sit too high lead to drive holes when starting off and belts that are too long have too little tension, which impairs power transmission.
We recommend replacing the V-belt regularly to ensure optimum power transmission. The maintenance intervals vary depending on the model, the general guideline is 6,000 to 8,000 km for 50cc scooters and 15,000 km (and more) for large scooters.
Dimensions: 873x23.4x11 mm / 28°
When to change the V-belt?
On scooters, the engine power is transmitted to the rear wheel via the V-belt or drive belt, which connects the CVT variator to the torque drive. As a rule, it should be replaced every 10,000 to 20,000 km. The belt slips when it is heavily worn. By the way, a new belt also slips and needs a short run-in period.
How to change the drive belt?
Replacing the V-belt is a relatively easy, you don't need advanced technical know-how. The first step is to remove the variator cover to get to the variator. You'll need a piston stopper and a blocking tool to remove the CVT and clutch bell. You can then remove the worn V-belt and replace it with the new one. When reassembling, make sure that the V-belt is properly seated and has the correct tension.
