Heidenau K67 2.75-21 45P TT

Heidenau K67 2.75-21 45P TT is a block-pattern tyre for the front wheel of dual-sport and trials motorcycles, the lightest in the K67 size range: 2.93 kg keeps weight off the bars and sharpens the response over bumps.

What K67 gives you

• Light front wheel: At 2.93 kg, this is the lightest fitment in the K67 range — the bars react faster over bumps and ruts.
• Large block tread: Widely spaced blocks bite into earth, grass and sand without clogging solid.
• Tube-type build (TT): Heidenau K67 is fitted with a tube — the familiar setup for spoked rims on dual-sport and trials bikes.
• Stable on tarmac: Despite the off-road pattern, Heidenau K67 keeps predictable behaviour through the corner on hard surfaces.

Rubber and carcass

In the 2.75-21 size, Heidenau K67 comes without an M+S marking and without a reinforced (Reinf) carcass — a light front-wheel fitment doesn't need extra sidewall reserve. The compound and pattern are built for mixed roads rather than deep mud: the tread holds less mud thanks to the gaps between the blocks.

Which bikes usually take the 2.75-21 size

The 2.75-21 (TT, front) size is often seen on modern trials machines — Beta Evo, GasGas TXT, TRS One RR — which typically run a 4.00-18 at the back, the same step Heidenau K67 offers within its own size range. It also turns up on dual-sport bikes such as the Yamaha XT250. 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 2.75-21 size is a light front-wheel tyre for the road and moderate dirt, not for competition trials — riders there swap tyres to match the course, and need a dedicated off-road tyre. For fast road bikes, road models with a higher speed rating are a better fit.

Who it suits

Heidenau K67 2.75-21 45P TT suits owners of dual-sport and trials motorcycles who need a light front wheel for everyday use: town, forest tracks, light dirt. The old-school tread pattern also makes Heidenau K67 a popular pick for scramblers and custom builds on old enduro donor bikes.
