Bridgestone S21 120/70WR17 Hypersport Tyre Front - Tubeless

The Bridgestone Battlax Hypersport S21 is a front motorcycle tyre engineered for high-performance sport and supersport machines. It sits in Bridgestone's hypersport category, targeting riders who demand strong dry-weather grip and confident, precise handling on public roads.

The 120/70WR17 fitment matches the standard front wheel specification found on most litre-class and middleweight supersport motorcycles. Tubeless construction and a W speed rating make it compatible with the performance envelope of modern sport bikes, while the radial build contributes to a consistent contact patch and predictable feel through corners.

• 120/70WR17 M/C front fitment — standard for litre-class and middleweight supersport motorcycles

• Tyre (single front tyre)

Check tyre pressure cold before every ride; always refer to your motorcycle manufacturer's recommended pressures for this tyre size — do not rely on the maximum pressure moulded on the sidewall.
Allow a break-in period of at least 100 km of normal road riding, progressively increasing lean angles and load so the compound reaches its optimal working temperature before pushing hard.
Have the tyre mounted, bead-seated and balanced by a qualified tyre technician using appropriate rim-safe equipment — improper fitting can damage the bead or cause air loss.
This tyre is designed to pair with the Bridgestone Battlax Hypersport S21 rear; confirm compatibility before pairing with a different brand or model.
Inspect the tread, sidewalls and bead area before each ride for cuts, cracking, embedded objects or abnormal wear patterns.
Replace when tread depth reaches the tyre's moulded wear indicator markers — riding beyond this point is unsafe and illegal.
Do not apply tyre dressing, silicone spray or chemical solvents to the tread or sidewall; if cleaning is required, use mild soap and water only, then rinse thoroughly.
A tyre with sidewall damage must be replaced — sidewall punctures or impacts that cause bulging are not repairable.
Store unmounted tyres lying flat or standing upright in a cool, dry location away from direct sunlight, ozone sources (motors, welding equipment) and petroleum products.
After extended storage, inspect carefully for compound hardening, cracking or flat-spotting before fitting to a motorcycle.
