Bridgestone’s line is “a sport radial that sharpens up the feet of an ’80s custom.” ★ All that remains is one 18-inch pairing, 110/80ZR18 front and 150/70ZR18 rear ★ Not aimed at current supersports so much as at custom builds on older bikes.
Across the six axes, Dry・Sport sits at 4 and Wet・Life・Warm-up・Comfort at 3. The six numbers land close together: an even set-up. Of the 19 tires in the Sport group, 15 carry 4 for Dry. 1 front sizes and 1 rear, mostly 18-inch.

| Wet | 3 / 5 |
| Life | 3 / 5 |
| Warm-up | 3 / 5 |
| Comfort | 3 / 5 |
| Sport | 4 / 5 |
