RACING CONTROL TYRE FOR FORMULA EXTREME
The next-generation Supersport race tyre developed and manufactured in the USA to specifically meet the needs of American racers and sportbike riders. MT Multi-Tread compound gives the D211 GP-A rear tyre unparalleled grip, excellent drive out of corners and superior on-track handling. Jointless Band (JLB) rear-tyre construction reduces tyre growth for cooler running and enhanced grip. The development of the first N-TEC—a rear design—was one of the most complex motorcycle projects ever undertaken by Dunlop. Producing a continuously wound, multi-compound tyre that delivered consistently fast laps was a major undertaking. Radial construction provided excellent line stability and eliminated circumferential tyre growth, which allowed the tyre to run cooler. The challenge was to engineer sidewall stiffness to produce consistent feedback or “feeling” for the rider as the bike transitioned from upright to full lean and back again. Numerous carcass materials were evaluated both for riding feel and for their resistance to heat and stress. The engineers settled on a nylon carcass overlaid two nylon breaker belts and a continuously wound JLB, aramid-fiber tread belt. The N-TEC front also utilizes radial construction with two nylon carcass plies and two aramid cut-breaker carcass belts.
