Triumph Bonneville T100 specifications
Triumph · Cruiser
Total Motorcycle lists the 2026 changes across the Bonneville family: the Bobber has a wider, more generously padded floating seat, the Speedmaster has wider seats for rider and passenger and straighter handlebars. The Scrambler 900 has a more refined chassis, upgraded Showa suspension and radial brakes for capability on and off the road.
It also describes Triumph's line from the Speed 400 TR series up to the Rocket 3 with 2,500cc, and says the Speed 400 and Scrambler 400 X launched in 2023 on a brand-new single-engine platform.

What Total Motorcycle says about the range
The T100 page itself is a short description within that release.
What the T100 hardware looks like
Triumph lists 41 mm cartridge forks, twin rear shock units with preload adjustment, a single 310 mm front disc with a Brembo two-piston axial caliper and a 255 mm rear disc with a Nissin two-piston floating caliper, both with ABS. The wheelbase is 57.1 in, the rake 25.5 degrees and the trail 4.1 in.
The bike weighs 503 lb wet, has a 31.1 in seat and a 3.8 gal tank, and makes 64.1 hp at 7,400 rpm with 59 lb-ft at 3,750 rpm.
T100 against the 900 and 1200 Bonnevilles
The T100 costs $1,400 less than the Scrambler 900 at $12,395 and $3,000 less than the T120 at $13,995. It is 11 lb heavier than the Scrambler 900 at 503 lb against 492 lb. Its power is the same 64.1 hp as the Scrambler's.
Its five-speed gearbox is one gear fewer than the 1200s'. It is the plain, low-cost Bonneville, and the T120 adds power and equipment for $3,000.
T100 or the Street Twin-style entry bikes
The T100 is the middle of the Bonneville range for price and power. At $10,995 it has a 900cc twin making 64.1 hp at 7,400 rpm and 59 lb-ft at 3,750 rpm, a five-speed gearbox, a single 310 mm front disc with a Brembo two-piston caliper and a 3.8 gal tank.
It costs $3,000 less than the T120 and $4,400 less than the Speed Twin 1200, and it weighs 503 lb, 10.7 lb less than the T120.
Its torque low in the rev range makes it a relaxed rider. Its price is why it is the standard choice for a first classic.
Equipment and what to add
Total Motorcycle's range note shows Triumph focusing its 2026 updates on the Bobber, Speedmaster and Scrambler 900 , so the T100 is a carry-over model. That means a 2025 T100 is essentially the same bike as the 2026 one, and a used example can save money.
Accessories such as heated grips, a comfort seat and luggage are the usual additions, and a rider who plans to add them should price the total.
