The Triumph Trident 660 (2021+) has a 805 mm (31.7 in) seat height and a 1401 mm wheelbase. For an average 175 cm rider that works out to about 7° of forward lean with the knees bent to about 81°, and that rider can get both feet flat on the ground. See the riding-position diagram above, and enter your own height and inseam to see your fit. The Triumph Trident 660 (2021+) is LAMS-approved (learner-legal to ride in Australia).
The Triumph Trident 660 (2021+) in the real world
The Trident 660 is Triumph’s friendly-middleweight, and the riding position is a big reason it earns that reputation. At 805 mm it has one of the lower seats in this group of nakeds, the triple is slim where your legs come down, and the bars sit close and high for a naturally upright torso with just a hint of forward lean. It’s an unintimidating, neutral cockpit — the sort of bike a rider stepping up from a learner machine can settle into without a fight.
That accessibility is the theme owners return to: light at the kerb, low enough to get a confident foot down, and roomy enough not to feel cramped for average riders. In Australia a LAMS version is sold with the same chassis and ergonomics, so the fit is identical whether you’re restricted or not. Taller riders (above roughly 188 cm) note the cockpit is a fraction compact for touring, showing up as a slightly tight knee bend, but for the vast majority the proportions land squarely in the comfortable middle.
Who the Trident 660 fits
One of the friendlier middleweights for shorter and newer riders — the 805 mm seat is low for the class and the slim triple lets legs drop straight down.
Riders 165–185 cm sit in the sweet spot: easy bar reach, upright torso, secure stop.
Very tall riders (over ~188 cm) fit but sit a touch folded on long rides; check the knee angle above if you plan to tour.
The Australian LAMS version shares the standard bike’s seat and geometry, so this fit result applies to both.
Common fit & comfort changes
Comfort seat — The stock seat is fine for commutes and firms up over distance; a padded replacement helps long rides and can slightly change the ground reach.
Bar risers — A small lift removes the last of the mild forward lean for a dead-upright stance — popular with commuters and wrist-sensitive riders.
Low seat — For the shortest riders, a reduced-height seat brings the already-low 805 mm figure down further for an even more planted stop.
Most of these can be previewed on your own body with the “Adjust the fit” sliders in the simulator above.
The Triumph Trident 660 (2021+) has a seat height of 805 mm (31.7 inches).
Can a 175 cm rider flat-foot the Triumph Trident 660 (2021+)?
On its 805 mm seat, a 175 cm rider (about 80 cm inseam) can typically get both feet flat on the ground on the Triumph Trident 660 (2021+). Taller or shorter riders differ — use the simulator to check your own ground reach.
What is the riding position of the Triumph Trident 660 (2021+)?
For an average 175 cm rider, the Triumph Trident 660 (2021+) riding position (also called the seating position) works out to about 7° of forward lean with a 81° knee bend. See the riding-position diagram to judge the posture for your own body size.
Is the Triumph Trident 660 (2021+) LAMS-approved?
Yes — the Triumph Trident 660 (2021+) is LAMS-approved, so it is legal for learner and provisional riders in Australia.
Is the Triumph Trident 660 good for beginners and short riders?
It’s one of the easier middleweights to start on. The 805 mm seat is low for the class, the triple is slim between your knees, and the bike is light and upright, so most riders get a confident foot down and an unstressed reach to the bars. Enter your inseam in the simulator above to confirm your stop.
Is the Trident 660 comfortable for taller riders?
Up to about 188 cm most riders are comfortable in its upright position. Beyond that the cockpit is a fraction compact and the knee bend tightens on longer rides. A comfort seat or peg tweak helps, but very tall riders who tour a lot may prefer a roomier naked — compare the knee angle above to be sure.
Seat height & wheelbase come straight from the manufacturer’s published specs, verified across the maker’s site, media reviews and spec databases.
Handlebar & footpeg positions aren’t published by any manufacturer. Where a true side-profile photo exists, we mark five reference points on it (front & rear axle, seat, grip, peg) and convert pixels to millimetres using the known wheelbase as the scale. Where it doesn’t, we research the grip and peg heights and estimate the horizontal reach from class-typical geometry.
Every result is cross-checked against how reviewers describe the bike’s posture (upright / sporty / committed), and each bike page carries a data-confidence badge so you can see how solid its numbers are.
The drawing is a clean schematic — one shared template per bike type (naked, sport, cruiser, adventure, touring, dirt), anchored to each bike’s real seat, grip and peg coordinates — so you compare riding positions, not paint jobs.
Your figure is a stick model built from your height and inseam using standard body-proportion ratios, then posed by inverse kinematics — hips on the seat, hands on the bars, feet on the pegs — with the same posture solver for every bike.
Bottom line: seat height & wheelbase are hard data; handlebar/footpeg geometry and ground reach are calibrated estimates (see each bike’s data-confidence badge). Always sit on the real bike before you buy.
