Heidenau K80 100/90-17 55H TL

K80 is the sports road model in the Heidenau range — built for riders who move quickly on tarmac and change direction often. The defining quality of Heidenau K80 is a high level of grip combined with strong wear resistance, delivered by a modern elastomer compound technology. The 100/90-17 size, with a load index of 55 (218 kg), is most often fitted to the rear wheel of road motorcycles up to 250 cc, although it is officially approved by Heidenau for use on either axle.

Key features

• Grip and service life — the defining quality of K80: the modern elastomer compound delivers a high level of grip and wears slowly at the same time.

• Quick direction changes: the tyre contour is designed for responsive handling — Heidenau K80 comes into its own through linked corners.

• Grip at lean: the shoulder area of the tread is developed separately, so Heidenau K80 maintains grip while leaned over, under both braking and acceleration.

• Predictability near the limit: the responses of Heidenau K80 remain predictable for the rider as grip approaches its limit — which is why the model has established itself in supermoto.

• Line stability: new materials in the layer beneath the tread keep Heidenau K80 on line through fast corners.

• Damping: the tyre construction smooths out small surface irregularities — Heidenau K80 rides more comfortably over broken tarmac than a sports road tyre is usually expected to.

Tread and construction

Heidenau K80 100/90-17 is a bias-ply tyre: the size designation carries neither a B nor an R. It is supplied tubeless (TL), suiting cast wheels and tubeless spoked rims alike. The H speed index permits use up to 210 km/h. The tread pattern is a road design with water-dispersing grooves.

Application

100/90-17 suits road motorcycles up to 250 cc: it is often seen on the Bajaj Pulsar 125 and Pulsar 150, Honda Stunner, Kawasaki W175 and W175 Cafe, TVS Raider 125 and Yamaha SZ. Note that K63 is also catalogued in this size — check the article number when ordering.

The matching tyre for the other axle is K80 80/100-17. For a calmer riding style where mileage matters more, the same size is available as an allround model: K66 100/90-17. Heidenau K80 carries no M+S marking — for cold-weather use Heidenau produces winter versions of other profiles, collected in the Heidenau winter motorcycle tyres section. The full range is in the Heidenau road motorcycle tyre catalogue.
