Pattern design Benefits
CO CONST NSTRU RUCTION: CTION: FRO FRONT NT
Higher camber thrust forces generated with increasing the lean angle. Better pressure distribution
Better handling and precision without losing the superb neutral feeling. Smaller Crown profile Contact patch Construction and Technologies Benefits
CO CONST NSTRU RUCTION: CTION: RE REAR AR
Together with optimized belt construction and groove positioning, it upgrades the rear feeling Increased cornering stability. 30% Less slip area in the contact area More adhesion and more grip Less wear due too reduced slip Better traction with controllable feeling Larger Crown profile Contact patch Benefits
CO COMPOUND MPOUND
New shoulder compound to tame the roads and give the right confidence on maximum lean angle. The new compound provides a larger micro contact patch. Higher grip Faster cornering High confidence in any conditions Benefits New compound

TRAC TRACK K TEST TEST RESULTS
*Test Conditions : Sugo circuit (JP), Honda CBR 1000 RR, 120/70ZR17 – 190/55ZR17, IP 2.3 bar front 2.5 bar rear.
Lap time comparison :
*based on a lap of 2 minutes
Higher stability of S21 allows Higher entering speeds Keeping a sharper line Exiting the corner faster with higher speed and acceleration. Cornering speed data :
