Many years of collaboration with Faio Racing and numerous endurance tests have resulted in a high-performance gearbox that is technically based on proven predecessors such as the X-TRA S and X-TRA LARGE. This transmission is also based on the same gearing and design, but differs in its specific width and the number of arms on the shift claw.
The great advantage of the X-TRA STRONG gearbox is that - like an original Piaggio gearbox - it can be installed completely without machining the engine block. At the same time, it guarantees maximum durability even with extremely high-torque engines over 40 Nm.
✅ Particularly stable, tuned tooth module
✅ Visibly high-quality tooth flank structure
✅ Ideal for powerful Vespa engines
✅ Plug and play - no housing machining required
A transmission for the highest demands - ideal for all those who want maximum stability, optimum transmission ratios and uncompromising suitability for everyday use combined in a genuine performance package.
