ADDITIONAL TIRE
FEATURES
- Official Tire of MotoAmerica Roadracing.
- Updated front and rear profiles increase footprints at more extreme lean angles for improved lateral grip.
- Carbon R has a longer molecule chain than conventional carbon and significantly more bonding points with polymers due to its smaller particle size, which all help the compound heat more effectively to improve tire warm-up time and grip.
- 2 Cut Belt construction in the front improves stability, turn-in, rider feedback, and allows for incredible trail braking.
- Jointless Tread (JLT) on the rear helps increase tire stability, reduces flex, and helps create a larger more consistent footprint during braking, cornering, and acceleration.
- Multiple compounds to meet the demanding requirements for all road racing courses and conditions.

Dunlop recommends that tire warmers be set at 70°-80°C for 45 minutes to 1 hour (maximum); tire performance degradation may occur if tires are subjected to repeated tire warming cycles, and/or temperatures/times in excess of these.
This chart excludes Daytona.
Width and Diameter are measured on recommended rim.
