Sports clutches - more traction for large-frame wheel tuning.
With the Largeframe in particular, it is absolutely essential not to limit tuning measures to the Cylinder, but also to adapt the periphery of the Engine accordingly. One of the most important areas here is the Clutch - because more power is of little use if it is not transferred cleanly to the transmission at the end.
Thanks to stronger Springs and an additional, fourth Clutch Friction Plate, the sports clutch can transfer power from the Engine to the transmission much better than the standard version. "Goodbye to slipping!" The sports clutch is available in sizes 108/96 mm and 115/108 mm. With a suitable primary pinion and minor modifications to the oil guide bar in the Clutch Cover and Crankcase, the 115 mm clutches can also be used in 125-150 cc models. The transmission ratio can also be varied using different Clutch Gear Cogs.
Conclusion: Perfect addition for road tuning!
SIP-TIP:
New Woodruff Key, new Castle Nut and cage are mandatory. Reinforcement of Springs recommended as a variation option. Don't forget SAE30 Gearbox Oil for the nightly clutch lining bath. The Ø 108 mm PX Clutches can also be installed in Vespa Sprint/Sprint Veloce/GTR/GT/TS/T4/GL/VNB-VBB Models if the appropriate Washer (3 mm) is available.
