Rider Profile

Best ForThis bike rewards experienced riders who are comfortable with aggressive geometry, high-rev power delivery, and sharp handling responses.
PurposeBuilt primarily for spirited sport riding and track days where its light weight and high-revving triple engine can be fully exploited.
Rider FitExpect a committed forward-leaning riding position with high footpegs and low bars that place significant weight on wrists and demand core strength during longer rides.
CharacterA razor-sharp, high-revving Italian supersport that thrives on precision cornering and thrilling top-end power rather than relaxed cruising.
Not Ideal ForThis is not a good fit for new riders, commuters wanting comfort, or anyone planning long-distance touring with a passenger.

2021 MV Agusta F3 800 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 2021 MV Agusta F3 800, with a cramped knee angle of around 75 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.
