The Metzeler RACETEC SM 125/75R42 is a motorcycle tyre developed for competitive and track-focused short lap riding where grip and feedback are critical. It is designed to deliver consistent performance under aggressive cornering and repeated high-load braking. The tyre’s compound and tread layout prioritise a precise contact patch and temperature stability to maintain traction across session lengths. Track-oriented compound and profile tuned for cornering stability ensure reliable lap times and predictable behaviour when leaned over.

Groove placement supports rapid water evacuation for brief wet patches while the construction maximises steering response and reduces deformation at high speed. The casing stiffness is tailored to even wear and sustained grip during fast direction changes. These attributes let riders push the limits with controlled feedback from the tyre surface.

For competitors this tyre provides quick warm-up, repeatable performance and confident braking distance from lean angles. It is a specialist choice for riders seeking measurable improvements in lap consistency and handling precision on circuit days.
