The grand prix 4000 s ii is the reference tire on the market and has already gone through many stages of evolution. We are giving the flagship a new face. The discreet bead strip makes it possible to perfectly color coordinate to the bike without forgoing Black Chili tread performance. We have also expanded the size range: an additional 28 mm version provides better grip under poor conditions, improved puncture protection and greater comfort. The proven cornerstones of the 4000 s ii remain unchanged: Vectran breaker for unsurpassed puncture protection, Black Chili compound for low rolling resistance and sensational grip - handmade of course in Germany.
