Rider Profile

Best ForBest suited to intermediate or experienced off-road riders who understand how to manage a light, low-power, high-clearance enduro bike over technical terrain.
PurposeBuilt as a dedicated hardcore enduro machine for trails, technical single-track, and competition-style off-road riding rather than commuting or highway travel.
Rider FitThe tall 920 mm seat height and lightweight 116 kg chassis demand decent leg length and standing-riding confidence, though the low mass makes it manageable for smaller riders willing to learn.
CharacterA purist, minimalist off-road tool that rewards skillful throttle and body-position control rather than outright horsepower, favoring finesse over brute force.
Not Ideal ForNot a good fit for riders wanting a comfortable highway tourer, a passenger-friendly bike, or a machine with strong straight-line speed.

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

Feet:

At 920mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with cannot reach comfortably on the 2019 AJP PR4 Extreme 240, with a cramped knee angle of around 80 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.
