Engine & Performance

Triumph’s 660 cc inline triple is the star here: a compact, liquid‑cooled DOHC unit with a 12‑valve head and a 240° crank for that signature triple cadence. With a bore x stroke of 74.0 mm x 51.1 mm and a 12:1 compression ratio, it spins eagerly to a 12,650 rpm redline. The headline figures—94 hp at 11,250 rpm and 68 Nm at 8,250 rpm—translate to a top‑end zing with a healthy midrange, ideal for slicing through city gaps and charging down on‑ramps without constant downshifts.

Fueling comes via multipoint sequential EFI with electronic throttle and 3 x 44 mm throttle bodies, giving crisp response in all conditions. The 6‑speed transmission pairs well with a wet, multi‑plate slip & assist clutch for lighter lever effort and added stability on aggressive downshifts. Triumph Shift Assist quickshifter (up/down) is fitted, elevating the pace on twisty roads and reducing fatigue on commutes.

Efficiency is part of the package too. Claimed consumption is 57.6 mpg (US) / 4.9 L/100 km, and the 14 L / 3.7 US gal tank supports solid range between stops. Final drive is by X‑ring chain for durability.

Handling, Comfort & Triumph Trident 660 Seat Height

The chassis is set up for agility without sacrificing stability. Geometry is neutral and confidence‑inspiring, with a 24.5° rake, 108 mm (4.25 in) trail, and a 1402 mm (55.2 in) wheelbase. Showa 41 mm USD SFF‑BP forks offer 120 mm of travel, while the Showa rear monoshock provides preload and rebound damping adjustment with 130 mm travel. Michelin Road 5 tires—120/70 R17 front and 180/55 R17 rear—add wet and dry grip that flatters newer riders and pleases veterans.

The Triumph Trident 660 seat height of 810 mm (31.9 in) strikes a sweet spot for a wide range of riders. Shorter riders will appreciate how easily they can get boots down at stops, while taller riders still have enough room to stay comfy around town or on a Sunday blast. The Triumph Trident 660 weight is 195 kg (429.9 lb) wet, and the balance makes low‑speed maneuvering—like U‑turns or filtering—feel predictable rather than twitchy. At pace, the combination of geometry, suspension tuning, and that sticky 17‑inch rubber encourages confident corner entry and clean exits.
