JT B7208 drive belt for Sym

The JT B7208 drive belt is an essential component for ensuring the proper functioning of Sym vehicles. Its design takes into account the various length specifications that may vary due to the measurement and production processes of different trapezoidal belt manufacturers. It is important to note that, although the measurements may differ, this does not compromise the functionality of the belt.

Length specifications are determined through various parameters, including external length (Le), internal length (Li), and pitch length, which is calculated at approximately 3/4 of the height of the belt according to DIN 2215 standards. Additionally, the tension of the belt, as indicated by the vehicle manufacturer, is a crucial factor for accurate measurement.

It is essential to refer to the specific assignments for your vehicle, as there may be different sizes of trapezoidal belts for a single model depending on the manufacturer. In particular, for Piaggio vehicles, it is advisable to pay attention to the oil pump belt, especially after a trapezoidal belt failure. The flying parts of a broken belt can damage the oil pump belt, which is located behind the variomatic and is not immediately visible. Checking its condition and replacing it if necessary is crucial, as a compromised oil pump belt can lead to piston seizure.
