Drive belt Malossi X-Kevlar Sym ADX TG 400 >2025

Drive belt Malossi X-Kevlar for SYM ADX TG 400 from 2025 onward, belonging to the Hyper Racing range and developed for CVT transmissions subjected to high temperatures and loads.

In an automatic transmission, the belt is responsible for transmitting torque between the variator and the rear pulleys. During acceleration, it continuously changes its working diameter between the pulleys, withstanding tension, flexing, friction, and high temperatures.

The X K Belt uses wear-resistant materials combined with Kevlar® inserts. This reinforcement helps limit belt deformation under load and increases its resistance to heat and abrasion, especially when the transmission is operating intensively.

In a worn belt, the loss of width changes the position at which it operates between the pulleys. This can alter the effective transmission ratio and cause poorer acceleration, RPM fluctuations, or less consistent response.

When replacing the belt, we also recommend checking the condition of the variator, rollers, guides, and pulley surfaces. A marked pulley or a component with irregular wear can alter the belt travel and reduce the service life of the new assembly.
