The OE tire sizes for the Triumph Tiger Sport 800 (2025–present) are 120/70R17 front / 180/55R17 rear. Below are tires in these sizes, compared across brands. OE rim widths are F3.50 / 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.

Pirelli describes “a grooved hypersport tire designed to draw the most out of the bike on road and track alike.” The street-facing version of the SC V4.
Sizes: F 110/70ZR17, 120/70ZR17 / R 140/70ZR17, 150/60ZR17, 180/55ZR17, 180/60ZR17, 190/50ZR17, 190/55ZR17, 200/55ZR17, 200/60ZR17
Pirelli calls it “the ultimate racing replica.” The (W) speed index positions it for track and road both. Being replaced by the V4, and the size range is shrinking.
Sizes: F 120/70ZR17 / R 180/55ZR17, 190/50ZR17, 190/55ZR17, 200/55ZR17
Pirelli calls it “the high-grip version of the Diablo Rosso IV.” More aggressive than the Rosso IV without throwing away life the way the Supercorsa does — the middle ground.
Sizes: F 110/70ZR17, 120/70ZR17 / R 150/60ZR17, 180/55ZR17, 180/60ZR17, 190/50ZR17, 190/55ZR17, 200/55ZR17, 200/60ZR17
Bridgestone calls it “the flagship Battlax.” Racing-tire compound in the shoulders front and rear, with the edges left slick. The new HE-MS Belt construction, proven in the FIM Endurance World Championship, appears on a front tire here for the first time. The current generation of the RS family.
Sizes: F 120/70ZR17 / R 180/55ZR17, 190/55ZR17, 200/55ZR17
The most track-focused entry in the catalogue’s Hypersport section. Sizes are 17-inch large-displacement only.
Sizes: F 120/70ZR17 / R 180/55ZR17, 190/55ZR17, 200/55ZR17
Michelin’s line is “real confidence on public roads and strong potential on track.” Track-leaning, but without giving up life the way the Cup family does.
Sizes: F 120/70ZR17 / R 160/60ZR17, 180/55ZR17, 190/50ZR17, 190/55ZR17, 200/55ZR17
Dunlop calls it “a premium sport radial for riders who want skill rather than speed.” Many OE fitments — CBR600RR, CB1000 Hornet, GSX-8S, Z900, Katana among them.
Sizes: F 120/70ZR17 / R 160/60ZR17, 180/55ZR17, 190/50ZR17
The generation before the Roadsport 2. Dunlop’s line is “a sport radial for riders who want skill rather than speed.” Multiple-tread construction at the rear.
Sizes: F 120/70ZR17 / R 180/55ZR17, 190/50ZR17, 190/55ZR17
A sport radial from the OE-fitment side of the range. The 120/60ZR17 and 160/60ZR17 are the fitment for the Honda CB400SF (’99 on).
Sizes: F 120/60ZR17, 120/70ZR17 / R 160/60ZR17, 180/55ZR17
Pirelli’s Japanese line for it is “banking by pure instinct.” A sport radial. It has 120/60ZR17, which makes it one of the few current sport tires that can do both ends of the CB400SF (NC42), and the small sizes (110/70R17 and so on) are there too.
Sizes: F 110/70R17, 110/70ZR17, 120/60ZR17, 120/70ZR17 / R 140/70R17, 150/60R17, 150/60ZR17, 160/60ZR17, 180/55ZR17, 180/60ZR17, 190/50ZR17, 190/55ZR17, 200/55ZR17, 200/60ZR17, 240/45ZR17
Pirelli calls it “the third generation of the Diablo Rosso family, a road sport tire for dry and wet alike.” The Rosso IV’s predecessor but still sold alongside it, and it keeps small sizes the IV does not — 130/70ZR16, 100/80R17 among them.
Sizes: F 130/70ZR16, 100/80R17, 110/70R17, 110/70ZR17, 120/60ZR17, 120/70ZR17 / R 140/70R17, 150/60R17, 150/60ZR17, 160/60ZR17, 180/55ZR17, 190/50ZR17, 190/55ZR17, 240/45ZR17
The Rosso III’s predecessor. Pirelli’s stated aim was “longer tire life on the road together with grip at full lean,” with a dual-compound rear. Only 17-inch large-displacement sizes remain.
Sizes: F 120/70ZR17 / R 160/60ZR17, 170/60ZR17, 180/55ZR17, 190/50ZR17, 190/55ZR17, 200/50ZR17
Bridgestone’s line is “the joy of turning, for every rider.” A hypersport radial. The small sizes — 110/70R17, 140/70R17, 150/60R17 — take it down to the CB250R, Z400, Gixxer 250 and MT-03 class.
Sizes: F 110/70R17, 120/70ZR17 / R 140/70R17, 150/60R17, 160/60ZR17, 180/55ZR17, 190/50ZR17, 190/55ZR17, 200/55ZR17
Bridgestone calls it “a true premium sport radial that draws more out of the machine and chases the joy of control.” Successor to the S20 EVO, with a rear compound developed using ULTIMAT EYE for both traction and wear life. Two generations behind the S22 and S23, but it keeps sizes the current generation dropped, such as 130/70ZR16.
Sizes: F 130/70ZR16, 120/60ZR17, 120/70ZR17 / R 160/60ZR17, 180/55ZR17, 190/50ZR17, 190/55ZR17
Michelin’s line is “a new standard for the sport tire, riding exactly as you intend.” Successor to the Power 5, and Michelin’s mainstay road sport tire.
Sizes: F 110/70ZR17, 120/70ZR17 / R 140/70ZR17, 150/60ZR17, 160/60ZR17, 180/55ZR17, 190/50ZR17, 190/55ZR17, 200/55ZR17, 240/45ZR17
Michelin describes it as “specialised for performance on the street.” The Power 6’s predecessor, still in the 2026 catalogue alongside it.
Sizes: F 120/70ZR17 / R 160/60ZR17, 180/55ZR17, 190/50ZR17, 190/55ZR17, 200/55ZR17
Michelin’s line is “usable around town while still answering sport riding.” A long seller. The 120/60ZR17 covers the front of the CB400SF (NC42).
Sizes: F 110/70ZR17, 120/60ZR17, 120/70ZR17 / R 150/60ZR17, 160/60ZR17, 170/60ZR17, 180/55ZR17, 190/50ZR17, 190/55ZR17
From the Harley OE Scorcher family, the sport entry. One pairing only: 120/70ZR17 and 180/55ZR17.
Sizes: F 120/70ZR17 / R 180/55ZR17
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.
Sizes: F 110/70R17, 120/60R17, 130/70ZR16, 110/70ZR17, 120/60ZR17, 120/70ZR17, 110/80ZR18 / R 140/70R17, 150/60R17, 160/60R17, 140/60R18, 150/60R18, 150/70ZR17, 160/60ZR17, 170/60ZR17, 180/55ZR17, 190/50ZR17
Dunlop’s line is “performance that lasts — the new standard premium touring radial.” Mostly aimed at large tourers, but the 120/60ZR17 and 160/60ZR17 make it a touring-leaning option for the CB400SF.
Sizes: F 120/60ZR17, 120/70ZR17, 130/70ZR17, 110/80R18, 120/70ZR18 / R 160/60ZR17, 160/70ZR17, 170/60ZR17, 180/55ZR17, 190/50ZR17, 190/55ZR17, 190/60ZR17, 140/70R18, 150/70ZR18, 170/60ZR18
The touring radial that preceded the Roadsmart IV. Dunlop’s line is “a touring radial that answers the grand tourer’s urge to keep going.” Few sizes remain, as the main ones have moved to the current generation. The 160/60ZR17 is the fitment for the Suzuki SV650 (’18 on).
Sizes: F 120/70ZR17 / R 160/60ZR17, 180/55ZR17
Dunlop calls it “an entry-level touring model based on the Roadsmart III, with a single-compound rear.” Positioned below the plain III on price.
Sizes: F 120/60ZR17, 120/70ZR17 / R 160/60ZR17, 180/55ZR17, 190/50ZR17
Bridgestone’s line is “long life that makes itself heard.” A touring radial. One of very few current road tires available in 110/80R19, which covers both ends of the CL250, and it also has 120/60ZR17 (CB400SF) and 150/70ZR17 (GB350S rear).
Sizes: F 120/60ZR17, 120/70ZR17, 120/70ZR18, 110/80R19, 120/70R19, 110/80ZR18, 120/70ZR19 / R 150/70ZR17, 160/60ZR17, 170/60ZR17, 180/55ZR17, 190/50ZR17, 190/55ZR17, 160/70ZR17, 160/60ZR18
Bridgestone aims it at “on-road-centred adventure touring.” Strong on 19-inch fronts — 110/80R19, 120/70R19, 100/90-19 — so it fits the front of the CL250, CL500 and 400X. Rears go up to 150/70R17 (CL family) and 160/60ZR17 (400X).
Sizes: F 120/70R15, 120/70ZR17, 110/80R18, 100/90-19, 110/80R19, 120/70R19, 120/70ZR19, 90/90-21, 90/90V21 / R 130/80R17, 140/80R17, 150/70R17, 160/60ZR17, 170/60R17, 170/60ZR17, 180/55ZR17, 190/55R17, 190/55ZR17, 150/70R18, 150/70ZR18
Bridgestone’s line is “confidence from a large gain in wet performance.” A sport touring radial built around shorter wet braking distances and more cornering grip. The generation before the T32 and T33.
Sizes: F 120/60ZR17, 120/70ZR17 / R 160/60ZR17, 180/55ZR17, 190/50ZR17
The mainstay sport tourer, sold on its wet performance. It reaches into 18 and 19 inch, which is a wide net. The catalogue lists it in both the Sport Touring and Trail sections.
Sizes: F 110/70ZR17, 120/60ZR17, 120/70ZR17, 120/70ZR18, 110/80ZR19, 120/70ZR19 / R 140/70ZR17, 150/60ZR17, 150/70ZR17, 160/60ZR17, 170/60ZR17, 180/55ZR17, 190/50ZR17, 190/55ZR17

The Road 6’s predecessor, still in the 2026 catalogue alongside it.
Sizes: F 120/60ZR17, 120/70ZR17 / R 150/70ZR17, 160/60ZR17, 180/55ZR17, 190/50ZR17, 190/55ZR17
A touring tire. Metzeler’s English copy is “ride longer, ride further, ride safer.” It reaches from bias 110/70-17 and 140/70-17 all the way to cruiser sizes (130/90-16, 150/80-16). There is no Japanese page for it; confirmed on the English site.
Sizes: F 100/90-16, 110/90-16, 130/90-16, 100/80-17, 110/70-17, 110/80-17, 120/60ZR17, 120/70ZR17, 80/100-18, 100/90-18, 3.25-19, 90/90-19, 100/90-19 / R 130/90-16, 150/80-16, 130/70-17, 130/80-17, 140/70-17, 140/80-17, 150/70-17, 160/70ZR17, 180/55ZR17, 190/50ZR17, 190/55ZR17, 90/90-18, 110/90-18, 120/80-18, 4.00-18
Dunlop describes “the traditional TT100GP pattern, optimised with current technology for the latest neo-classics running radials.” A different tire from the bias TT100GP, aimed at radial-shod machines such as the Z900RS and the XSR family.
Sizes: F 120/70ZR17, 110/80R18 / R 150/70ZR17, 160/60ZR17, 180/55ZR17, 140/70R18
A touring/cruiser radial on Dunlop’s FS-JLB construction. The 120/70R18 and 160/60R17 are the fitment for the Kawasaki Vulcan S (’15 on).
Sizes: F 120/70ZR17, 120/70R18 / R 160/60R17, 180/55ZR17
Size 120/70-17: 46 exact, 0 in the same group. Shop links carry each tire’s own matching size.
Pirelli calls it “the latest of the fastest track tread tires Pirelli makes, and hugely backed on the circuit.” The usage icon is racetrackOnly. Several compounds exist (SC1, SC2 and so on), but Pirelli does not split them by size on the site, so we keep it as one entry.
Sizes: F 110/70R17, 120/70R17 / R 120/70R17, 140/70R17, 150/60R17, 160/60R17, 180/60R17, 190/55R17, 200/55R17, 200/60R17
Bridgestone describes “a premium high-grip radial delivering handling, grip and stability in the dry.” Slick-like tread with 3D groove shapes. It has been an OE fitment on Japanese manufacturers’ high-end machines. Bridgestone recommends it for “customers who ride everything from winding roads to the circuit.”
Sizes: F 120/70ZR17, 110/70R17 / R 190/50ZR17, 140/70R17, 150/60R17
Sold alongside the Power Cup 2. This is the one that carries the middleweight sizes — 110/70ZR17, 140/70ZR17 and so on.
Sizes: F 110/70ZR17, 120/70ZR17 / R 140/70ZR17, 150/60ZR17, 160/60ZR17
Pirelli calls it “Pirelli’s sporty tire for everyday use.” Bias construction, for smaller machines. The 14- to 17-inch small sizes make it one of the few sport options for the Grom, Monkey 125 and CB125R class.
Sizes: F 90/90-14, 100/80-14, 120/70-14, 70/90-17, 80/90-17, 90/80-17, 100/80-17, 110/70-17, 120/70-17 / R 90/90-14, 100/80-14, 100/90-14, 120/70-14, 70/90-17, 80/90-17, 90/80-17, 100/80-17, 110/70-17, 120/70-17, 130/70-17, 140/70-17, 150/60-17
Bridgestone credits “grip and light handling from front- and rear-specific patterns and purpose-developed compounds.” One generation behind the S23. ★ Only one pairing survives on the official site: 120/70ZR17 front, 180/60ZR17 rear ★ The main sizes have moved to the S23.
Sizes: F 120/70ZR17 / R 180/60ZR17
IRC calls it “a modern road-going bias tire tuned for the quarter-litre class.” Unlike the RX-01 every size is tubeless, and it covers the MT-25 / Z250 sizes (110/70-17, 140/70-17).
Sizes: F 100/80-17, 110/70-17, 110/80-17, 120/70-17 / R 120/80-17, 130/70-17, 130/80-17, 140/70-17, 150/70-17, 140/70-18, 150/70-18
The default bias tire for the 250 class. Dunlop credits “grip and long life from the latest compound.” A broad size range that covers most 17- to 19-inch naked bikes.
Sizes: F 100/90-16, 120/80-16, 70/90-17, 100/80-17, 110/70-17, 110/80-17, 120/70-17, 90/90-18, 100/80-18, 100/90-18, 110/90-18, 100/90-19 / R 130/90-16, 80/90-17, 120/80-17, 130/70-17, 130/90-17, 140/70-17, 150/70-17, 110/80-18, 110/90-18, 120/80-18, 120/90-18, 130/70-18, 130/80-18, 140/70-18, 150/70-18
Two generations before the Roadsmart III. The 18-inch tourer sizes are what remain. The 120/70ZR17 and 160/60ZR17 are the fitment for the Kawasaki ER-6F / ER-6N (’12 on).
Sizes: F 120/70ZR17, 120/70R18 / R 160/60ZR17, 200/50R18
A standard bias tire in 17 and 18 inch. Dunlop marks the 140/80-17 and 150/70-18 as while-stocks-last.
Sizes: F 110/80-17, 110/70-17, 120/70-17, 110/80-18, 120/70-18 / R 140/80-17, 140/70-17, 150/70-17, 160/70-17, 150/70-18
Sport touring on a bias construction. One of very few current tires offered in both 100/90-19 and 130/70-18, which lets you set up a GB350 front and rear on the sporting side.
Sizes: F 110/90-16, 120/80-16, 110/70-17, 110/80-17, 120/70-17, 100/90-18, 110/80-18, 110/90-18, 100/90-19 / R 130/90-16, 150/80-16, 130/70-17, 130/80-17, 130/90-17, 140/70-17, 150/70-17, 120/90-18, 130/70-18, 130/80-18, 140/70-18
The touring bias standard. Bridgestone’s line is “wet performance you can lean on — the definitive touring bias, further developed.” First choice if you ride in the rain.
Sizes: F 100/90-16, 110/90-16, 120/80-16, 100/80-17, 110/70-17, 110/80-17, 120/70-17, 90/90-18, 100/80-18, 100/90-18, 110/80-18, 110/90-18, 3.25-19, 100/90-19, 90/90-21 / R 130/90-16, 150/80-16, 120/80-17, 120/90-17, 130/70-17, 130/80-17, 130/90-17, 140/70-17, 140/80-17, 150/70-17, 4.00-18, 110/80-18, 110/90-18, 120/80-18, 120/90-18, 130/70-18, 130/80-18, 140/70-18, 150/70-18
Bridgestone files it as “mainly ON.” An OE adventure fitment, and only one pairing exists: 120/70ZR17 front, 160/60ZR17 rear. It is not chasing off-road ability, so we list it on the Road side (same call we made for the A41).
Sizes: F 120/70ZR17 / R 160/60ZR17
Bridgestone files it as “mainly ON,” and both ends are OE fitments. Despite the Trail Wing name there is no knobby pattern; it is an adventure-styled road tire. ★ The 160/60R15 rear makes it one of the very few options for the X-ADV ★ Bridgestone notes that “this is a rare size and delivery may take time.”
Sizes: F 120/70R17, 110/80R19 / R 160/60R15, 130/80R17, 150/70R17
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.
Sizes: F 110/70-17, 120/70-17, 110/80-18 / R 140/70-17
From the Harley OE Scorcher family. One pairing only: 120/70R17 and 160/60R17.
Sizes: F 120/70R17 / R 160/60R17
Size 180/55-17: 32 exact, 0 in the same group. Shop links carry each tire’s own matching size.
