Rider Profile

Best ForThis bike suits intermediate to experienced riders who are comfortable with strong midrange punch and a firm, sporty chassis.
PurposeIt's built for spirited backroad blasts and canyon carving where its punchy triple and aggressive geometry can shine.
Rider FitThe 830mm seat height and forward-leaning naked riding position demand reasonably fit riders comfortable with a bit of wrist and wrist load on longer stints.
CharacterRaucous, characterful and a bit rebellious, the TNT 899 rewards an assertive throttle hand with an exotic-sounding in-line triple.
Not Ideal ForThis isn't the right choice for new riders seeking a forgiving first bike or for anyone prioritizing plush comfort and long-distance touring ease.

2017 Benelli TNT 899 Rider Ergonomics Assessment

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

Feet:

At 830mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with balls of both feet on the 2017 Benelli TNT 899, with a relaxed knee angle of around 130 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.
