Rider Profile

Best For	Well suited to newer riders and returning riders thanks to its approachable power delivery, low seat height, and forgiving manners, while still having enough character to satisfy more experienced owners looking for a relaxed second bike.
Purpose	Built primarily as a stylish, easygoing modern classic for commuting and weekend rides rather than outright performance or long-distance touring.
Rider Fit	Its low 765mm seat height and modest 216kg weight make it accessible to shorter riders and easy to manage at a standstill or in tight parking situations.
Character	A torquey, characterful parallel-twin roadster that prioritizes smooth, tractable real-world power and classic British styling over outright speed.
Not Ideal For	Not the right choice for riders chasing high-speed thrills, serious off-road capability, or a dedicated long-haul touring setup with passenger comfort and wind protection.

Your height

Inseam (optional)

Units

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

Feet:

At 759mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2020 Triumph Street Twin, with a moderate knee angle of around 115 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.
