Bridgestone Battlax Hypersport S21 Front & Rear Tire Set | 120/70ZR17 + 180/55ZR17

Most supersports and middleweight nakeds leave the factory on a 120/70 front and 180/55 rear, and replacing both ends together keeps the handling the bike was set up with. This set pairs the Battlax Hypersport S21 front and rear in that fitment, so you replace as a matched pair in one order.

What's In The Set

• Front: Bridgestone Battlax Hypersport S21 120/70ZR17 58W, tubeless
• Rear: Bridgestone Battlax Hypersport S21 180/55ZR17 73W, tubeless

Fitment

• The standard fitment for most 600-750cc supersports, including CBR600RR, YZF-R6, ZX-6R, and GSX-R600/750
• Any bike running 120/70ZR17 front and 180/55ZR17 rear

Fitment Notes and Exclusions

• Many liter bikes take a 190/50ZR17 or 190/55ZR17 rear. This set does not fit those bikes, so check your rear sidewall first.
• Confirm both sizes on your current sidewalls before ordering.

Why the Battlax Hypersport S21

The S21 is an earlier-generation Battlax street hypersport radial and remains a strong value choice for fast street riding. The rear uses a dual compound, harder in the center for mileage and softer on the shoulders for cornering grip, and the lightweight construction gives quick, light steering. If you want Battlax hypersport handling without paying for the latest generation, the S21 is the pick.

Both tires ship together as a matched set.
