Metzeler released information, photos and technical data on its newest supersport motorcycle tire, the Racetec RR (Road Racing). The Racetec RR replaces the Racetec Interact model and purports to maintain high grip in all conditions while at the same time producing the precision, stability and consistency sport riders demand.

Metzeler attained 39 podium finishes in 2014, including 16 major road races. Using feedback from the riders and technical information gathered from the crews, Metzeler refined the Racetec platform to produce the RR. The RR was tested at the North West 200, Ulster Grand Prix, Southern 100 and at the Isle of Man TT, where Triumph rider Gary Johnson won the Supersport class with the RR tires.

While one might make the assumption that the Racetec RR is meant only for hardcore racing, Metzeler assures that the RR’s K3 (hard) compound is aimed squarely at street riders on supersport and naked bikes who seek “the ultimate in dry grip on the road.” The K1 (soft) and K2 (medium) compounds are, however, intended for track or road course racing use, with the K1 useful in lower temperature settings or on more aggressive road surfaces.

One big difference between the Roadtec RR and a dedicated racing slick is that the RR is meant to deliver higher mileage without any fade to the grip characteristics to the tires. To that end, Metzeler improved the abrasion resistance of the tires using a more uniform dispersion of materials in a patented mixing process.

All Roadtec RR tires are “Z”-rated radials suitable for speeds over 149 mph (240 kph) and feature a bi-compound “cap and base” construction on the rear tires that disperses heat generated by long runs at high speeds on straightaways throughout the tire’s special substrate layer to promote temperature uniformity and improve grip in turns. Under maximum weight loads, all RR tires are “W” speed rated (up to 168 mph/270 kph)


All Roadtec RR tires are currently available only for 17” wheels, and the only front tire size available is a 120/70.

The K1 (soft) compound is available for rear tires in sizes 180/60 and 200/55 .

The K2 (medium) compound is available for rear tires in sizes 160/60, 180/55, 180/60, and 200/55.

The K3 (hard) compound is available for rear tires in sizes 160/60, 180/55, 190/50, and 190/55.
