Rider Profile

Best For	Well suited to beginners and relaxed riders thanks to its low power and easygoing, predictable manners.
Purpose	Built for laid-back cruising and classic-styled commuting rather than outright performance.
Rider Fit	The low seat height and moderate weight make it approachable for shorter or less experienced riders.
Character	A charming, torquey single-cylinder classic that rewards a relaxed, unhurried riding style.
Not Ideal For	Not the right choice for riders seeking high speed, sharp handling, or serious off-road capability.

Units

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

Feet:

At 760mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2007 Enfield Thunderbird 350, with a moderate knee angle of around 110 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.
