The Metzeler Racetec SM Rear K2 NHS 165/55R17 0 is a competition-oriented motorcycle rear tyre intended for trackday and race use on specialised circuits, offering focused grip for high-performance small-displacement machines. It is built for experienced riders and teams who prioritise maximum traction and predictable heat build-up under repeated high-load laps. This NHS (Not for Highway Service) tyre is optimised solely for closed-course environments.

A soft, high-performance compound provides excellent contact patch adhesion at elevated temperatures, translating to strong traction exiting corners and reduced sliding tendency. The sculpted tread promotes heat management and consistent surface temperature, while the carcass construction delivers precise steering response and sustained cornering stability through fast transitions. The profile is calibrated to balance wear characteristics across aggressive lines, supporting competitive mileage in racing contexts. Cornering stability is a hallmark of the design and the tyre’s compound supports rapid warm-up for immediate grip, with steering response that helps riders place the bike accurately on apexes.

On track this tyre gives confident lap-to-lap performance, allowing riders to push harder with consistent feedback and predictable limits. Its race-focused construction reduces lap time variability and supports competitive consistency for club and national events.
