Metzeler Racetec SM Rear K1 NHS 165/55R17 0 is a race-oriented rear motorcycle tyre designed for track use and sprint competition. It suits riders seeking maximum traction for short, intense sessions and is optimised for bikes competing in supervised track events. The tyre is not for road use and targets the sportbike segment where grip and quick warm-up matter. High-temperature performance and rapid heat build-up for race conditions are core attributes that track riders expect and receive here.

The construction features a race compound and asymmetric profile tuned to increase the contact patch under lean and acceleration. Multiple compound zones enhance cornering stability while the carcass geometry promotes consistent tyre behaviour lap after lap. Drainage channels are minimised to favour mechanical grip on dry circuits and the tread design supports even wear during repeated heat cycles. Precision steering response and predictable slip thresholds help extract lap time without compromising control.

For the rider this tyre delivers strong braking performance and confident drive out of corners, translating to faster sector times. It also offers a dependable load capacity for competitive setups and consistent feedback through the rear end. Choosing this Metzeler gives a clear performance advantage on track days and short race formats where traction and stability are decisive.
