Rider Profile

Best ForThis bike suits experienced off-road and motocross riders comfortable with a tall, aggressive, high-strung competition machine.
PurposeBuilt purely for motocross racing and serious off-road riding, not for street use or general transportation.
Rider FitIts tall 37.8-inch seat height, light 249 lb wet weight, and firm long-travel suspension demand good rider fitness, strength, and confidence standing on the pegs.
CharacterA razor-sharp, high-revving, race-bred single-cylinder motocrosser that rewards aggressive input with explosive acceleration and pinpoint handling.
Not Ideal ForThis is not the right bike for beginners, commuters, passengers, or anyone seeking comfort, storage, or highway touring capability.

2009 Honda CRF450R Rider Ergonomics Assessment

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

Feet:

At 955mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with cannot reach comfortably on the 2009 Honda CRF450R, with a cramped knee angle of around 85 degrees and an upright 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.
