Rider Profile

Best ForThis is a machine best suited to intermediate and experienced riders who are comfortable with a high-revving, powerful triple and committed sportbike ergonomics.
PurposeBuilt primarily for spirited road riding and canyon carving, with genuine track-day capability thanks to its aluminum perimeter frame and sharp geometry.
Rider FitThe low, forward-leaning riding position and firm suspension demand decent core strength and wrist tolerance, especially on longer rides.
CharacterThe 955i in-line three delivers a distinctive, torque-rich growl and mid-range punch that gives it a more characterful feel than typical four-cylinder sport rivals.
Not Ideal ForThis is not the right bike for new riders, tall touring distances with a passenger, or anyone seeking a relaxed, upright commuting experience.

2004 Triumph Daytona 955I Rider Ergonomics Assessment

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

Feet:

At 815mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2004 Triumph Daytona 955I, with a cramped knee angle of around 70 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.
