The Metzeler RACETEC SM RAIN 125/75R42 0 is a specialised motorcycle rain tyre developed for racing and track-day use in wet conditions. It is intended for riders who need maximum grip and confidence on soaked circuits where consistent lap times and safety are crucial. The tyre sits in the competition-oriented segment and focuses on extracting grip from standing and flowing water. Water evacuation and a generous contact patch are engineered to keep traction high under heavy lean angles.

Advanced tread geometry with deep circumferential grooves channels water away from the contact area to preserve wet grip and shorten braking distance on slippery surfaces. The compound is optimised for cold, wet track temperatures to deliver consistent adhesion without sacrificing feedback. A stiff carcass enhances cornering stability while allowing precise steering response for aggressive lines. Cornering stability and lateral control are priorities in the tyre’s design.

Riders will appreciate confident turn-in and secure exits even in persistent rain, which lowers the risk of aquaplaning during competition. The tyre provides the technical foundation for pushing performance in adverse weather, helping to keep lap times stable and predictable. In short, it offers a focused combination of safety and competitive edge for wet-track riding.
