Heidenau K73 M+S SiO2 160/60-17 69H TL

Heidenau K73 M+S 160/60-17 69H is a winter road motorcycle tyre for 17-inch wheels, with a Silica compound made for the cold below +7 °C. The 160/60-17 size fits the rear wheel of road and naked motorcycles; it shares the tread pattern of the summer K73, but the compound and the M+S marking are built for winter.

Key features

• Silica winter compound: The winter compound of Heidenau K73 M+S stays flexible at low temperatures, where a summer tyre goes hard and loses grip.
• Snow and slush: The high-drainage tread of K73 M+S bites into snow and slush and resists polishing over on slippery surfaces.
• Cold, wet tarmac: The M+S marking and the Silica compound work together for grip on cold, wet roads where an ordinary tyre has already let go.
• Speed rating: The H speed index permits sustained riding at speeds up to 210 km/h — with margin to spare for the bikes that run this size.

Tread and construction

Heidenau K73 M+S uses a bias-ply construction in tubeless (TL) form and carries the M+S marking. The winter tread pattern clears water and slush, while the Silica compound handles grip in the cold and on wet surfaces. It is this pairing — a winter tread with a Silica compound — that keeps K73 M+S working where a summer tyre no longer does, at and below around +7 °C.

Which motorcycles use the 160/60-17 size

The 160/60-17 rear (paired with a front 120/70-17) is a typical fitment for midsize road and naked motorcycles. It is often seen on models such as the Kawasaki Ninja 650 and Z650, Honda CB500F and CBR500R, CFMoto 650NK, Royal Enfield Guerrilla 450 and Benelli Leoncino 500. Treat this as a guide to the class of bike rather than a guarantee of compatibility — check the exact fitment against your motorcycle's manual.

When you actually need the winter K73 M+S

Heidenau K73 M+S is for the cold season: sub-zero temperatures, snow, slush and cold wet tarmac. If temperatures stay above +7 °C, the summer version of the same tread — Heidenau K73 160/60-17 — is the better buy, as it lasts longer on warm tarmac. Note: M+S means the tyre is rated for mud and snow, but it is not studded and is no guarantee on ice — on sheet ice any friction tyre is limited.
