Bridgestone X31 110/90-19 MX/Enduro Tyre Rear

The Bridgestone Battlecross X31 is a motocross rear tyre built for intermediate, or medium, terrain — the loamy, tilled and lightly hard-packed surfaces that make up most motocross tracks and trail loops. This listing covers the 110/90-19 62M rear fitment, the standard rear size for full-size motocross and enduro machines.

The X31 pairs Bridgestone's Castle Block rear tread design with Anti-Degradation Fin technology, a combination aimed at holding grip and block shape as the tyre heats up over a moto. Compared with its predecessor, Bridgestone reports gains in traction, braking, cornering grip, bump absorption and block durability, along with a wider terrain operating range.

Suited to riders who want one rear tyre that copes with changing track conditions rather than a specialist soft- or hard-terrain option. This is a competition off-road tyre and is not intended for use on public roads.

Have the tyre fitted and balanced by a qualified motorcycle tyre fitter — off-road carcasses are stiff and easily damaged by incorrect levering technique.
Check that the size and load/speed rating suit your machine before fitting, and follow your motorcycle manufacturer's recommended tyre pressures for the conditions you're riding in.
Observe any rotation-direction marking on the sidewall so the tread pattern faces the correct way.
If your wheel uses a rim lock, make sure it is correctly seated and tensioned, and fit a fresh, correctly sized tube where a tube is used.
Scrub the tyre in with a few easy laps or a gentle first session before riding at full pace, so the new tread surface can bed in.
Check pressures cold before every ride, and re-check after the first ride or two while the tyre beds onto the rim.
Inspect the tread before and after each outing for cuts, tears, torn or chunked blocks, and exposed carcass; retire the tyre if any of these appear.
Clean with mild soap and water only — keep petrol, solvents, brake cleaner, chain lube and tyre-shine dressings off the tread and sidewalls.
Store spare or off-season tyres flat or upright in a cool, dry, dark place away from direct sunlight, ozone sources such as electric motors, and chemicals.
This is a competition off-road tyre and is not intended for public road use — grip, wear and wet-weather behaviour on sealed roads will not match a road-legal tyre.
