The Duro HF903 in 90/90-21 is a tubeless motorcycle tyre in one of the most common front wheel sizes fitted to trail and dual-sport machines. It carries a 54S load and speed rating and a 4 ply rating casing.
It suits riders replacing a worn 21-inch front tyre and looking for a straightforward, budget-conscious option. Check the size, load index and speed symbol specified for your motorcycle before ordering, and have the tyre fitted and balanced by a qualified tyre fitter.

- Have the tyre fitted and balanced by a qualified tyre fitter using correct tyre-changing equipment and a new valve or valve seal where applicable.
- Confirm the size, load index (54) and speed symbol (S) meet or exceed the specification listed for your motorcycle before fitting.
- Fit only to a rim in sound condition and suited to the tyre; if your wheel requires an inner tube, have your fitter confirm the correct tube and setup.
- Ride conservatively for the first 150-200 km so the new tread surface can scuff in and gain full grip, avoiding hard acceleration, heavy braking and deep lean angles.
- Check and adjust cold inflation pressure at least fortnightly and before long rides, using the pressure specified by your motorcycle manufacturer.
- Inspect regularly for cuts, embedded objects, bulges, sidewall damage and uneven wear, and replace the tyre if any are found.
- Replace the tyre before the tread reaches the legal minimum depth in your state, and note that tread wear indicators in the grooves show when the limit is reached.
- Do not exceed the tyre's rated load or speed, and do not run it under-inflated, as both cause overheating and casing damage.
- Store spare tyres upright in a cool, dry, dark place away from direct sunlight, ozone sources such as electric motors, and fuels, oils or solvents.
- Clean with mild soap and water only; avoid solvents, tyre dressings and silicone-based shine products, which can degrade rubber and reduce grip.
