Race primary repair kit from DRT - CNC Cover Plate and Reinforced Springs as a Fitting Solution for High Performance Engines.

Race primary repair kits are mainly used for very powerful Engines. They consist of a CNC-milled aluminum cover plate/cover disk and four reinforced Springs that act as shock absorbers. Unlike riveted versions, these kits are bolted together.

• CNC-milled aluminum Cover Plate with 4 Reinforced Springs
• Fitting instead of riveted - designed for high loads
• Variants from DRT (Sport/Race) and high-quality solutions from PLC-CORSE

DRT supplies threaded spacers, PLC-CORSE has integrated these into the Cover Plate. Two versions are available from DRT:

• The "Sport" variant with green or red Springs for common standard primary ratios.
• The "Race" version with stronger yellow Springs and an enlarged spring seat for Engines with even more power.

PLC-CORSE describes itself as the "Home of Italian finest Vespa tuning" - and the parts are manufactured to a correspondingly high standard. The PLC Repair Kit is not only very popular in the Italian racing scene.

Conclusion: Engine damage due to broken shock absorber springs or worn primary kits are a thing of the past with these Repair Kits.
