Heidenau K67 3.00-21 51T TT

Heidenau K67 3.00-21 51T TT is a block-pattern tyre for the front wheel of road-enduro motorcycles on a 21-inch rim — a size closer to modern adventure bikes than to trials.

What K67 gives you

• Mid-weight front wheel: At 3.61 kg, this sits in the middle of the K67 size range — a balance between light steering and reserve for longer rides.
• Large block tread: Widely spaced blocks bite into earth and grass without clogging solid.
• Tube-type build (TT): Heidenau K67 is fitted with a tube — the familiar setup for spoked rims on road-enduro motorcycles.
• Stable at speed: On tarmac, Heidenau K67 holds its line at motorway speeds, not just on back roads.

Rubber and carcass

In the 3.00-21 size, Heidenau K67 comes without an M+S marking and without a reinforced (Reinf) carcass — built for mixed roads and motorway miles rather than deep mud. The tread holds less mud thanks to the gaps between the blocks, and on tarmac the tyre keeps predictable behaviour through the corner.

Which bikes usually take the 3.00-21 size

Heidenau K67 in the 3.00-21 size is often seen on modern road-enduro models built for the motorway as much as the dirt — the Honda XR650L, Kawasaki KLX300, Italika DM250X and Hartford VR-220HX, for instance. Treat this as a guide to size, not a guarantee of fitment — check the axle and mounting against your bike's manual.

Where K67 is not the right choice

Heidenau K67 in the 3.00-21 size is built for the motorway and moderate dirt, not for hard enduro or trials — that calls for a dedicated off-road tyre. For pure road bikes, road models with a speed rating above 51T are the better fit.

Who it suits

Heidenau K67 3.00-21 51T TT suits owners of road-enduro motorcycles who spend as much time on tarmac and motorway as on the trail. Choose your size and order K67 with delivery across Kazakhstan — browse the full Heidenau adventure tyre catalogue.
