The Triumph Speed 400 and Scrambler 400 X entered the lineup for model year 2024, offering an affordable launching point into Triumph ownership for new riders. Following customer requests for more off-road capability, the Scrambler 400 XC, announced in the summer of 2025, was joining the lineup for 2026. The 400 family continues to grow with the announcement of the 2026 Thruxton 400 and 2027 Tracker 400.
Both models receive a new version of the 398cc single-cylinder TR-Series engine, while the other three 400 models retain the original engine. The new TR is said to deliver 5% more peak power and has a higher rev limit with stronger top-end performance. Claimed figures are 41.4 hp at 9,000 rpm and 27.7 lb-ft of torque at 7,500 rpm (compared to 39.5 hp at 8,000 rpm and 27.7 lb-ft at 6,500 rpm for the other 400s). Triumph claims the increase is thanks to new internals like a revised camshaft profile, along with a new tune.
As the model names imply, the Thruxton is a cafe-racer-styled machine, while the Tracker is styled after flat-track bikes. Both models get a new tubular-steel main frame, but their subframes differ. The bikes also feature different suspension setups. Both get a 43mm inverted big-piston fork and a gas rear monoshock with preload adjustment. The Thruxton’s fork offers 5.3 inches of travel, while the Tracker offers a longer 5.5 inches of travel. Both have 5.1 inches of rear travel.
The Thruxton offers a sportier riding position than the other 400 models, with new clip-on handlebars that are 1.6 inches narrower and 9.7 inches lower than the Speed 400’s bar. The footpegs are more rearset, positioned 3.4 inches farther back and 1.1 inches higher. Other unique features include a shortened rear fender, a number plate hanger, an upswept sports silencer, and bar-end mirrors. Its 17-inch cast-aluminum wheels are wrapped in Pirelli Diablo Rosso IV tires. It has a seat height of 31.3 inches, a wheelbase of 54.2 inches, and a wet weight of 388 lb.
The Tracker’s riding position is highlighted by a wide handlebar that’s 0.9 inches broader and 5.3 inches lower than the handlebar on the Speed 400. The footpegs are 3.4 inches farther back and 1 inch higher. It offers sculpted knee cutouts in its tracker-styled fuel tank, as well as a fly screen, color-matched seat cowl, and twin upswept silencers. Its cast-aluminum 17-inch wheels are wrapped in Pirelli MT60 RS dual-purpose tires. The Tracker has a seat height of 31.7 inches, a wheelbase of 53.9 inches, and a wet weight of 381 lb.
Both bikes include an analog speedometer and an LCD tachometer, along with a USB-C charging port, switchable traction control, a torque assist clutch, and ABS.
The 2026 Thruxton 400 will be available in Phantom Black and Aluminum, Pearl Metallic White and Storm Gray, or Metallic Racing Yellow with Aluminum Silver starting at $6,295 and arriving to dealerships in March 2026. The 2027 Tracker 400 will be available in Aluminum Silver Gloss, Racing Yellow, or Phantom Black starting at $5,995 and arriving in April 2026.

Triumphs small displacement bikes really move the soul. I bought a KTM 390 a couple years back and the fun factor of these small bikes really is high. And the cool factor from Triumph is really setting the bar high.
I aged out of motorcycling last year, but these Triumphs are certainly tempting. Affordable, 150 pounds lighter than my last bike, and really nice looking.
Tim,
I am 74 and finally had to sell my Harley. Just getting to heavy and found myself not riding it any more. Bought a Speed 400 and now I back riding. Much easier to get in and out of the garage. No trouble cruising at 70 to 75mph. Fun again to ride around town and out of 35 bikes I’ve owned in the past, it the smoothest of the all.
I’m also 74 and my 1200 BMW has been sitting unridden for the last 3 years. But I bought a 300 pound dual sport and have had a blast with it. I’m drooling over the new line of Triumphs. One of my best ever bikes was a Triumph Sprint ST and I love the brand! The Tracker is looking really good to me!
The Thruxton looks sweeeeeet!
At 89, my 6 month-old Triumph “Speed 400″ is very manageable although seat height is too high for my 31” inseam. At 2115 miles, it has been trouble-free and averages over 80 miles per US gallon of fuel. Suspension is overly stiff but the bike handles well. Gearing is abysmally low, but I have the sprockets ordered to make the gearing as I prefer. Build quality appears to be excellent and I’ve had no trouble at all with it.
A Speed 400 is my 88th bike in 89 years and is an excellent bike for new riders as well as older ones unhappy with 500# (and up) bikes that seem to be the norm. Build quality is excellent and I’ve had no trouble in over 2000 miles in 6 months. Fuel mileage is in the low 80 mpg range per USA gallon. Ultra-low gearing is a common complaint and I have two sprockets on order that will sort that out. The excellent Internet forum, “Triumph 400 Owners” is composed primarily of very experienced riders, with the preponderance over age 50. Quite a few forum members are riders who left the fold and returned in response to this lively little bike. Maintenance intervals are very long (valve clearance checks at 20,000 miles; oil changes at 10,000 miles).

Oops!! I thought my first attempt at posting a reply had been lost in cyberspace and I began another. Really, it’s not my age!

You don’t stop riding motorcycles because you got old; you got old because you stopped riding motorcycles. Trust me.
