About this tire
Bridgestone's short-course minibike racing tire — “born to win minibike races.” Compounds: YCX (soft) and YCY (medium); the rear YCZ (hard) has been discontinued. The official page says nothing about street legality, so it is listed as unconfirmed here.
Across the six axes, Dry・Sport sits at 5 and Comfort at 1. A tire set up to be good at some things and to give up others. Of the 14 tires in the Race group, 11 carry 5 for Dry. 1 front sizes and 1 rear, mostly 12-inch.

Where to buy
How to read this
- The 1–5 ratings are our own estimates. Not manufacturer figures, not measurements.
- Within one model, character and street legality both change with the size and the spec. Confirm with the manufacturer or a dealer before you buy.
- Shop links go to search results rather than product pages. Other sizes and older models will be mixed in.
- “Narrower” means one or two steps below the OE size. The “rim width OK” badge means the tire maker's published rim widths line up with the OE rim width; no badge means unconfirmed.
- Competition tires may not be used on public roads.
