Rider Profile

Best ForWell suited to beginner and intermediate riders thanks to its modest power delivery and predictable, low-stress character.
PurposeBuilt as a relaxed classic cruiser for easy commuting and leisurely weekend rides rather than outright performance.
Rider FitThe low seat height and manageable weight make it accessible to riders of most sizes, though the cruiser stance suits taller riders best on longer rides.
CharacterA charming, torque-friendly single that rewards a laid-back riding style with thumping classic engine feel over speed or sharp handling.
Not Ideal ForNot a good fit for riders seeking high-speed performance, aggressive cornering ability, or serious off-road capability.

2018 Enfield Thunderbird X 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 X 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.
