Your tyres
Classic & retro
Modern compounds in the 18- and 19-inch sizes classics use.
Classic sizes on 18- and 19-inch wheels need tyres made for them. Modern classic tyres keep the period look and light steering with far better wet grip.

How buying works
Know your sizes
Stock is 100/90-19 front, 120/80-18 rear. Check them against your owner’s manual or the swingarm sticker.
Order a matched pair
Tap a tyre’s Tyroola link, enter each size, and add front and rear in the same model. Afterpay and Zip are offered.
Get them fitted
Have them delivered to a motorcycle shop that fits supplied tyres, and ring first to book: most charge less if you bring the wheels in off the bike. New tyres are slippery for the first 100–200 km, so build up lean gently.
For your bike
Fit a matched pair
Run the same make and model front and rear. Tyres are designed as a pair, and mixing them changes how the bike steers and where it lets go. Rears usually wear out first; if you replace only the rear, match the front's model.
Scrub new tyres in
New tyres are slippery until the release agent wears off. Take the first 100–150 km gently, building lean angle gradually, and be extra careful in the wet and on painted lines.
Check pressures weekly, cold
Bike tyres lose air faster than car tyres and pressure changes the handling more. Check them cold, before you ride, against your owner's manual or the swingarm sticker, and add the pillion figure when two-up.
Wet and cold mornings
Bike tyres need heat to grip. On cold mornings the first few kilometres are the riskiest: brake early, keep lean angles small, and watch for paint, tar snakes and leaves.
Replace by age as well as tread
Rubber hardens with age even when there's tread left. Check the DOT date code and replace tyres older than about five years, sooner if they're cracked.
