Description
Drive belts have to be replaced after a while to ensure optimum power transmission. Dayco Drive Belt Vespa GTS / GTS Super / GTV / GT 60 250-300cc is a V-type polyamide belt with excellent grip to avoid belt slippage. They are more durable and robust that the original belts and can also be used in tuned engines.
Note - a new drive belt has to be run in for a while before it works 100% correct.
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.
