Heidenau K 67 3.00-21 Enduro/Trial Front Motorcycle Tyre

The Heidenau K 67 3.00-21 is a German-made enduro and trial front motorcycle tyre. It is built for machines running a 21-inch front rim. That covers enduro bikes, trial machines and dual-purpose road/off-road motorcycles. The tyre mounts on the front wheel only. Its tread pattern is shaped for mixed surfaces rather than one single terrain.

The 3.00-21 size is the classic front dimension on enduro and dual-sport motorcycles. Because of that narrow profile, the tyre answers steering input precisely on tight trails. Riders get accurate line control through forest tracks and rocky climbs. On tarmac, meanwhile, the behaviour stays predictable during connecting sections.

This tyre uses a bias-ply (diagonal) casing with a TT (TubeType) construction. It carries load index 51 and speed index P. The weight is 3.65 kg. A tube is required for use and is not included in the package.

Key Benefits

• Enduro and trial tread – solid grip on gravel, clay and rock surfaces.
• Predictable road manners – connecting town sections can be ridden calmly.
• Bias-ply construction – the casing absorbs impacts and lateral loads well.
• 3.00-21 dimension – accurate steering plus solid directional stability.
• TT (TubeType) casing – reliable sealing with a tube and simple trailside repair.
• Load index 51 – rated for loads up to 195 kg.
• Speed index P – approved for speeds up to 150 km/h.
• Made in Germany – consistent build quality and even wear.

Who Is This Tyre For?

The Heidenau K 67 3.00-21 suits enduro motorcycles, trial motorcycles and universal dual-purpose models. The one requirement is a 21-inch front rim. That diameter is standard on most enduro and dual-sport machines, so fitment is straightforward.

This tyre is aimed at riders who cover mixed ground on the same trip. Typical use includes forest tracks, gravel roads, clay and rocky terrain. In addition, it works well for trial-style training sessions. Slow technical riding is another area where the tread pattern earns its place.

Note that this is not a pure motocross tyre. It is not a pure road tyre either. Instead, one tyre covers both off-road stages and the linking roads between them. Riders who need only tarmac performance should look elsewhere.

Technical Specifications

Why Choose the Heidenau K 67 3.00-21?

Heidenau is a German manufacturer focused purely on two-wheel tyres. The company produces tyres for motorcycles, scooters, mopeds and classic machines. The K series is one of its most recognisable lines. Within that series, the K 67 represents the enduro and trial tread pattern.

Rather than narrow specialisation, this tyre covers a wider field of use. It is neither a dedicated motocross tyre nor a dedicated asphalt tyre. As a result, a single front tyre handles off-road stages and connecting roads alike. That matters on long mixed-surface rides.

The diagonal casing was chosen over a radial construction for a reason. This design absorbs impacts better on rocky ground. Furthermore, the TT setup allows a puncture to be repaired simply on the road. Both choices favour riders who spend real time away from tarmac.
