Rider Profile

Best ForFriendly and predictable enough for newer riders moving up, yet has enough punch and a characterful triple engine to keep experienced riders engaged.
PurposeDesigned as a versatile everyday roadster that excels at commuting, weekend blasts, and learning to ride briskly rather than as a dedicated track or long-distance tool.
Rider FitA low seat height and modest 195kg wet weight make it approachable and manageable for riders of varying heights and confidence levels.
CharacterThe 660cc triple delivers a smooth, torquey, and vocal power delivery that feels lively without being intimidating.
Not Ideal ForNot the ideal choice for riders wanting serious off-road capability, high-speed track dominance, or dedicated two-up long-haul touring comfort.

2024 Triumph Trident 660 Rider Ergonomics Assessment

Calculated in your browser only - your height/inseam are never sent to our servers.

Feet:

At 805mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2024 Triumph Trident 660, with a relaxed knee angle of around 120 degrees and a forward-leaning riding position.

Data quality: measured. Assumes about 30mm of suspension sag once seated (a typical street-bike rule of thumb - stiffer or softer suspension will vary). This is an approximation from category-typical geometry and generic body proportions, not a measurement of this specific bike or you - sit on it before you buy.
