120/70-17 Motorcycle Tyre Price - From R1 330

120/70-17 motorcycle tyre prices currently start from R1 330 at Sharwoods Bike Tyre. Prices are per tyre, and sticky sport compounds or big adventure tyres cost more than commuter rubber, so compare the table above by brand and shop before you buy.

120/70-17 is a front fitment on most bikes that use it; the matching rear is a wider size on the same or a smaller rim. Always confirm against the sizes in your owner's manual or on the swingarm sticker before ordering.

The letter before the rim size shows the construction. ZR and R mean radial; a dash or B means bias-ply (crossply). Shops often write radials with a dash too, which is why we group every 120/70-17 listing on one page. Fit the construction your bike's manual specifies, and do not mix radial and bias between front and rear unless the manufacturer approves it.

That depends on your rim, not the tyre size. Cast alloy wheels and spoked rims with sealed beds run tubeless (TL). Conventional spoked rims leak air at the nipples, so they need a tube even inside a tubeless tyre. A tube adds heat, so check that the tyre's speed rating still covers your bike when you run one.

The legal minimum in SA is 1mm of tread across the full width, but wet grip falls away well before that. Replace at around 2mm, when the rear squares off, after any puncture near the sidewall, or once the tyre is about five years old (check the four-digit DOT date on the sidewall) even if the tread looks fine.
