Rider Profile

Best ForSuits riders with some experience who want a nimble, forgiving middleweight rather than a beginner-only commuter or an intimidating superbike.
PurposeBest suited to spirited backroad riding and everyday commuting where light weight and balance matter more than outright power.
Rider FitA relatively low seat height and modest 184 kg wet weight make it manageable for shorter or less physically strong riders.
CharacterA lightweight, mono-shock naked v-twin with sporty geometry that rewards smooth, precise inputs rather than raw horsepower.
Not Ideal ForNot the right choice for riders wanting long-distance touring comfort, passenger-friendly plushness, or any off-road capability.

1991 Honda NT 650 Hawk GT Rider Ergonomics Assessment

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

Feet:

At 777mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 1991 Honda NT 650 Hawk GT, with a relaxed knee angle of around 120 degrees and a forward-leaning riding position.

Data quality: estimated (wheelbase estimated from this category's typical bike, not this model's own spec). 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.
