About this tire

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 22 tires in the Sport group, 18 carry 4 for Dry. 1 front sizes and 1 rear, mostly 18-inch.

OE sizes can differ by model year and market — the sidewall of your own bike is the sure reference. This is a Japanese-market lineup; the sizes themselves are international.
