FAQs

Can I use the Metzeler Racetec SM on public roads?

No, this tyre is marked NHS (Not for Highway use) and is designed exclusively for closed-course racing.

What does the K2 compound designation mean?

K2 represents the medium compound, which offers a balance of grip and durability across a wide range of racing temperatures.

Do I need to use tyre warmers with these tyres?

Yes, for professional performance and safety, it is highly recommended to use tyre warmers to bring the rubber to operating temperature before use.

How do the radial grooves help in off-road sections?

The grooves are engineered for self-cleaning, helping to shed dirt and debris quickly when re-entering the asphalt section of a Supermoto track.

Is this tyre suitable for front or rear fitment?

This specific model is designed for rear fitment; please check the Metzeler catalogue for compatible front tyre counterparts.

Troubleshooting

Excessive or abnormal wear patterns

Check your motorcycle's suspension sag and compression settings; incorrect bike geometry can cause premature compound degradation.

Reduced grip during initial laps

Ensure you are using tyre warmers to reach operating temperature before entering the circuit; the K2 compound requires heat to function correctly.

Feeling of instability in dirt sections

Verify cold tyre pressure settings, as off-road sections may require minor pressure adjustments to maximize carcass damping.

Pros and Cons

Pros

  • Excellent traction in both asphalt and off-road conditions
  • Predictable slide characteristics for high-level Supermoto racing
  • Effective self-cleaning tread design for mixed-surface racing

Setup, Compatibility & Care

Proper setup is vital to unlocking the potential of the Racetec SM. Always ensure that tyre pressures are adjusted according to track-specific ambient temperatures and your motorcycle's suspension settings. As these are competition tyres, they perform optimally when used in conjunction with tyre warmers to reach their target operating temperature before hitting the track. Inspect the tyre surface after every session for debris or excessive wear. For storage, keep the tyres in a cool, dry area away from direct sunlight and electrical equipment, as the racing compounds are sensitive to environmental degradation.
