Scrambler Icon / Dark / Nightshift / Full Throttle tires
The OE tire sizes for the Ducati Scrambler Icon / Dark / Nightshift / Full Throttle (2023–present) are 110/80R18 front / 180/55R17 rear. Below are tires in these sizes, compared across brands. OE rim widths are F3.00 / R5.50 (from official specs; used for the rim-width check). 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.

Dunlop describes an “all-round touring radial covering town riding through to winding roads.” A default for 250–400 radial-shod bikes, and the 120/60ZR17 makes it fit the CB400SF. Dunlop notes explicitly that the rear must not be fitted to rims outside the approved width.

Bridgestone files it as an “on-road high-performance type” bias tire. The sizes land on the 17-inch ends of 250–400 naked bikes. As Bridgestone’s own note says — “this is a rare size and delivery may take time” — availability is not good.

Where to buy
Bridgestone calls it “a touring bias with a long sales record, built on all-round performance matched to what riders actually need.” Silica in the compound for wet performance, and a sport-sact rear. ★ The Japanese lineup has shrunk to two front and three rear sizes; almost none of the small diameters that made it a staple are left ★

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.
