Specifications

Will it work with your bike?

Match the 140/70ZR17 rear size and 66W load/speed rating to your owner's manual or the tire placard. Dunlop lists rim widths of 3.75 or 4.50 in. for this size. Rim diameter alone does not confirm fit.

This is a radial tire: fit radials only where your motorcycle manufacturer approves them, and do not mix radial and bias tires unless the motorcycle or tire manufacturer approves the combination. It is tubeless; mount it without a tube only on a wheel approved for tubeless tires. If your wheel requires a tube, Dunlop does not recommend fitting a non-radial tube in a radial tire.

Sold individually. Check fit before mounting: mounted tires cannot be returned. Need a fit check? Send us your bike's year, make and model or call (970) 637-6000.
