The 'Race' primary drive repair kits are usually used in the more performance orientated setups. The 'Race' primary drive repair kit has strengthened aluminium spring retainer plates and reinforced primary drive shock absorber springs. These items are held together using screws and are not riveted.
DRT include a threaded spacer with their kit, the PLC version has this feature integrated into the spring retainer plate. DRT has two versions available:
The 'Sport' item has green springs and is compatible with most original PIAGGIO primary drive assemblies.
The 'Race' kit is supplied with stronger, yellow springs and larger cut-outs for the springs to sit in. This second version is intended for use with more performance orientated motor setups.
PLC-Corse title themselves as “the home of finest Italian tuning” and their modesty does not deceive seeing the very high quality of their race proven components. Their solid reputation has not only been earned on the race track, but also with high power street tuning projects.
Conclusion: Motor damage caused by broken damper springs or worn primary drives is now preventable.
SIP-TIP: These high end primary drive repair kits really show their true worth in combination with a suitably strong race clutch. Do not forget to order a new woodruff key, clutch nut and safety basket and fresh gear box oil with these kits for safe and enduring use of your motor.
