The Reed Valve Block TPR from TOP PERFORMANCES is a precision-manufactured spare part for Vespa smallframe and largeframe models with PK, XL, XL2, PV, ET3, VNB-TS, VBA-Super, Rally, PX and PE Lusso Engines. Developed for use with MALOSSI diaphragm intake manifolds (77 × 49 × 35 mm) and equipped with a 4-flap design without stops, this block significantly improves the filling of the crankcase on sport-tuned engines thanks to variable diaphragm guidance. The constructive design enables optimized gas-air guidance and reduces flow resistance, whereby an increase in performance can be achieved, especially at high engine speeds. Insert as a spare part enables easy integration into existing tuning setups while ensuring long-lasting functionality.
