Rider Profile

Best ForThis bike suits new-to-intermediate riders thanks to its modest power and forgiving, low-stress delivery.
PurposeIt's built for relaxed cruising and classic-style commuting rather than outright speed or sport riding.
Rider FitThe low seat height and manageable weight make it accessible for shorter or less experienced riders, though the wide bars and cruiser stance suit a relaxed upright posture.
CharacterIt has an old-school single-cylinder thumper charm, prioritizing steady torque and classic looks over performance.
Not Ideal ForIt's not for riders seeking high-speed thrills, aggressive cornering, or serious off-road capability.

2018 Enfield Thunderbird 500 Rider Ergonomics Assessment

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

Feet:

At 775mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2018 Enfield Thunderbird 500, 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.
