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.
Updated Black Chili tread compound with carbon nano particles delivers 26% lower rolling resistance, 30% more grip and 5% longer mileage, plus it’s self-cleaning
Vectran Breaker belt is lighter and tougher than aramid belts, 5x stronger than steel and resists water, punctures and cuts
3-ply casing and 330 TPI provide additional reinforcement
Tread wear indicators help you gauge the true life of the tire, eliminating premature replacement or overuse
