Heidenau Inner Tube 14 C – 34G Valve

Heidenau 14 C fits the 2½/2¾, 2.50, 2.75, 3.00, 60/100, 80/80, 80/90 size range for 14-inch rims — one of the widest-fitting size groups for light motorcycles and scooters.

The wall here is thinner than in the Cross class — 1.5–2.0mm: enough for everyday road riding.

Material and durability

Heidenau 14 C is made from natural rubber: the material resists mechanical stress better than synthetic compounds and holds elasticity for longer. The trade-off: it loses pressure slightly faster than synthetic rubber, so check pressure with a gauge from time to time.

Valve and fitment

Heidenau 14 C comes with a standard-length, straight 34G valve — a simple, reliable choice where no bend angle or extra stem length is needed.

Application

Heidenau 14 C suits motorcycles, scooters and mopeds with a 14-inch rim under normal road conditions. Natural rubber retains elasticity better at low temperatures in Kazakhstan's winter, but ages faster than some synthetic materials during prolonged use in summer heat.

Fitting recommendation

When fitting Heidenau 14 C, check the length of the original valve and use a new rim tape of the correct size. Pinching the tube with tyre levers remains one of the most common causes of premature tube failure.
