The Brand

Bridgestone is a Japanese manufacturer founded by Shojiro Ishibashi, whose surname translates as 'stone bridge', the source of the company name. It produces tyres for passenger cars, SUVs, commercial vehicles, motorcycles and aircraft, alongside diversified rubber products, and in 1988 acquired Firestone. A premium marque suited to drivers seeking established quality and a broad range.

The Pattern
BT S21 Rear

Premium hypersport radial rear tyre with a triple-compound design for sports riders wanting grip and mileage.

The S21 rear is a premium hypersport radial developed as the evolution of the S20 EVO, using Bridgestone's ULTIMAT EYE technology to sharpen handling and cornering feel. Its triple-compound (5LC) construction blends a durable centre with grippier shoulder rubber, giving strong traction when cranked over while extending tread life. A larger crown profile improves stability and reduces slip mid-corner, and updated tread grooves maintain wet performance. It suits sports and supersport riders who want confident dry grip with usable everyday mileage.

  • Triple-compound 5LC rear construction
  • Larger crown profile for cornering stability
  • Developed with ULTIMAT EYE contact-patch technology
  • Improved dry grip and traction when leaned over
  • Longer tread life over the previous S20 EVO
Best for Sports and supersport machines on fast road riding, with occasional track days
