Best for
Built as a purebred competition enduro machine, it excels at tackling technical trails, tight woods sections, and demanding off-road terrain.
Built for
It has the light, flickable, high-revving personality of a race-focused single-cylinder enduro bike that rewards active, aggressive riding.
Not ideal for
It is not a good choice for riders wanting a comfortable commuter, a passenger-friendly bike, or long-distance paved touring.

Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.

At 940mm, a rider of 68.9" with a 31" (estimated) inseam will not reach the ground comfortably on the 2017 Beta RR 4T 400, with a cramped knee angle of around 85 degrees and an upright riding position.

Assumes about 30mm of suspension sag once seated. This is an approximation from category-typical geometry, not a measurement of this bike or of you - sit on one before you buy.
