Speed Twin 1200 against its siblings
The Speed Twin costs $1,400 more than the T120 at $13,995 and $4,400 more than the T100 at $10,995. It weighs 476 lb wet against 513.7 lb and 503 lb. So it is the lightest of the three.
Its seat is 31.7 in against the T120's 31.1 in. The Speed Twin is the sporty one, with a hard-edged ride the owners describe, while the T120 is the relaxed one.
What it is like to live with
The owner reviews split, and the reasons are useful. Riders who love it cite the ride quality, the power and the all-day comfort; riders who dislike it point to the fork that cannot be adjusted, a seat that lasts about an hour, a snatchy throttle in Sport mode at low speed, and brakes that bind a little at low speed.
Those are complaints about set-up and personal fit, and a test ride will show which group you fall into.
The 22.4 degree rake and 55.6 in wheelbase make it the sharpest steerer in the Bonneville range, and the 476 lb weight is the lowest.
Speed Twin against the T120 in practice
Both bikes use a 1,200cc twin. But the Speed Twin has 103.5 hp and 83 lb-ft against the T120's more relaxed tune, upside-down Marzocchi forks against the T120's 41 mm Kayaba telescopic fork, Marzocchi rear shocks with external reservoirs against a simpler unit, and twin radial-caliper front brakes against Nissin two-piston calipers. That equipment explains the $1,400 price gap and the sportier ride.
The Speed Twin is the bike for a rider who wants the retro look with performance, and the T120 is the more relaxed all-rounder.
Speed Twin 1200 against the Bonneville T120 and R 12 nineT
Triumph's Bonneville T120 is the softer sibling, and BMW's R 12 nineT is the closest roadster rival.
Triumph Speed Twin 1200 — specification referenceMotorcycle News says Street Twin owners who want more oomph, 49 percent more power and 40 percent more torque, will love the Speed Twin, as will Bonneville T120 riders who want a bit more of everything.
It summarizes the bike as taking the best bits from the raciest retros and laidback roadsters: fast, fun, all-day comfy and easy to manage, and despite modest suspension and braking hardware, with good ride quality.
An owner complains that the lack of an adjustable fork makes for a hard ride, that the seat is bearable for one hour, and that the throttle is snatchy at slower speed in Sport mode.

Triumph Speed Twin 1200 questions
How much power does the Triumph Speed Twin 1200 make?
Triumph rates the 1,200cc twin at 103.5 hp at 7,750 rpm and 83 lb-ft at 4,250 rpm. Motorcycle News says that is 49 percent more power than the Street Twin.
Is the Speed Twin 1200 ride hard?
One owner review complains of a hard ride because the fork is not adjustable and the seat is bearable for about an hour. While Motorcycle News calls it all-day comfy.
The Triumph Speed Twin 1200 is Triumph's 1,200cc sport roadster, a liquid-cooled SOHC 270-degree parallel twin rated at 103.5 hp and 83 lb-ft with a six-speed gearbox and an X-ring chain. Triumph asks $15,395.
The roadster's controls deserve a direct fitting
Speed Twin 1200 and the cruiser-shaped Bonnevilles can share an engine-family description without offering the same riding position. Try the bar reach, pedal position and seat support on the actual Speed Twin. A rider choosing a day-trip roadster may prefer that arrangement; a passenger-focused plan may call for a different comparison. Displacement and a photograph of the tank cannot answer the fitting question.
On a used bike, ask whether the suspension, exhaust or final-drive gearing has been altered. Identify the parts and the work recorded rather than accepting a list of brand names as proof of an improvement. Compare the offered configuration with the model-year handbook and retain the original parts where available. The useful purchase question is whether this motorcycle, as equipped and maintained, answers the intended riding, not whether its accessories were expensive when new.
