Heidenau K60 front 3.00-21 51T TT

K60 is the base model of the Heidenau K60 family: the manufacturer's recommended split is 40% tarmac and 60% gravel. Within the family, K60 Scout is set up for roughly equal road and dirt, while K60 Ranger is built for serious off-road (30/70). The front 3.00-21, with a load index of 51 (195 kg), suits classic 250–650 cc enduros.

Key features

• Grip on tarmac and gravel: the large-block tread pattern holds on unpaved lanes and on the tarmac stretches between off-road sections alike.
• Self-clearing: wide grooves and large gaps between the lugs throw mud out as you ride, so the pattern doesn't clog on a soft, wet track.
• Mileage and grip: Heidenau names the combination of the two as a defining property of the K60 — a selected compound works together with a purpose-built carcass.
• Comfort on the road: Heidenau K60 is built to get you to the dirt section comfortably along the tarmac.
• Spoked wheels: the tube-type (TT) build suits classic spoked rims.

Tread and construction

Heidenau K60 carries a classic block enduro tread with a high proportion of open space. The TT (tube-type) version carries a T speed index, permitting speeds up to 190 km/h. The 3.00-21 comes with the front tread variant — K60 front. The standard K60 carries no M+S marking. For winter use, Heidenau produces separate K60 M+S versions with a silica-based (SiO₂) compound — you can see them in the Heidenau winter motorcycle tyres section.
