Heidenau K67 3.25-19 54T TT

Heidenau K67 3.25-19 54T TT is a block-pattern tyre in the 19-inch fitment; on classic single-cylinder motorcycles this size usually runs at the front, with the neighbouring 3.50-19 at the back of the same bike.

What K67 gives you

• Front half of the pair: On bikes that run different K67 sizes front and rear, 3.25-19 is the front position — lighter to steer than the rear 3.50-19.
• 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 classic single-cylinder motorcycles.
• Front-or-rear fitment: The 3.25-19 works on either wheel — on bikes that carry this size on both axles.

Rubber and carcass

In the 3.25-19 size, Heidenau K67 comes without an M+S marking and without a reinforced (Reinf) carcass — built for mixed roads rather than deep mud. The tread holds less mud thanks to the gaps between the blocks, and on tarmac the tyre responds to the bars without delay — a benefit of the lighter front-position build.

Which bikes usually take the 3.25-19 size

Heidenau K67 in the 3.25-19 size (TT, front/rear) is most often found on the front wheel of classic single-cylinder motorcycles — older-generation Royal Enfield Bullet Electra Deluxe and Thunderbird TwinSpark, for instance, which run a 3.50-19 at the back. 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

The front-pair Heidenau K67 3.25-19 is built for the road and light dirt, not for serious off-roading — that calls for a dedicated off-road tyre. For pure road riding at higher revs, road models with a higher speed rating are the better fit.

Who it suits

Heidenau K67 3.25-19 54T TT suits owners of classic single-cylinder motorcycles who need a front wheel for everyday use: town, forest tracks, light dirt. The same old-school tread pattern is popular with scrambler and custom builders working on these motorcycles — valued for the ride and the look alike.
