Heidenau K80 SR 100/90-12 64M TL SRS2 NHS

NHS — Not for Highway Service. Heidenau K80 SR SRS2 is intended for closed circuits and training sessions. It must not be fitted to machines used on public roads.

K80 SR SRS2 is the racing version of the K80 SR scooter profile — a tyre engineered from the ground up for the track. The carcass of Heidenau K80 SR SRS2 is weight-optimised specifically for racing, yet withstands the high loads of circuit use. The 100/90-12 size, with a load index of 64 (280 kg), is approved for either axle.

Key features

• Weight-optimised carcass — the basis of this model: designed for racing and, despite its light weight, able to take the loads of the circuit.
• Stability: the combination of new construction and matched geometry gives Heidenau K80 SR SRS2 an extremely high level of stability.
• Behaviour at the limit: the limit of grip arrives gently on Heidenau K80 SR SRS2, so very steep lean angles become available as the rider's skill develops.
• Feedback: the K80 SR tread delivers responsive handling, excellent line-holding and precise feedback through the bars.
• Wet-weather reserve: the tread pattern gives a markedly increased safety margin in the wet — uncommon for a racing tyre.
• SRS 2 (Soft) compound: recommended for ambient temperatures from 0 to 25 °C.

Tread and construction

Heidenau K80 SR SRS2 100/90-12 is a bias-ply tyre: the size designation carries neither a B nor an R. It is supplied tubeless (TL). The tread pattern is taken from the road-going K80 SR — those characteristics form the best basis for a racing tyre. The speed index is M. The NHS marking means the tyre is not approved for public roads.

Application

Heidenau K80 SR SRS2 100/90-12 is intended for racing scooters and pit bikes on closed circuits. The soft compound works between 0 and 25 °C, which also makes the tyre suitable for indoor winter training.

The matching tyre for the other axle is K80 SR 120/80-12 SRS2 NHS. For the road-going version of the same profile rather than the racing one, see the K80 SR road scooter tyres. The full track range is in the racing tyre catalogue for scooters and pit bikes.
