Heidenau K80 140/70-17 66H 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 140/70-17 size, with a load index of 66 (300 kg), is specified by Heidenau for rear-axle installation.

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 140/70-17 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

140/70-17 belongs to road motorcycles of 250–450 cc: it is often seen on the Yamaha YZF-R3 and R25, Suzuki GSX250R, SWM SM 125 R, Harley-Davidson X440 S, Jawa 350 CL Bobber and Hanway Furious 300NK.

The matching tyre for the other axle is K80 110/70-17. For a calmer riding style where mileage matters more, the same size is available as an allround model: K66 140/70-17. 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.
