Rider Profile

Best ForBest suited to riders with some off-road or trials background, as the bike's light weight and tall stance reward balance and technical skill more than raw experience.
PurposeBuilt specifically for technical trials riding and obstacle navigation rather than speed, distance, or road use.
Rider FitIts featherweight 101 kg dry mass and slim profile make it very easy to muscle around and hold up, though the tall 850 mm seat height demands decent leg reach.
CharacterA pure, minimalist trials tool that thrives on razor-sharp low-speed agility, tractable low-end power delivery, and total rider control over the bike's balance.
Not Ideal ForNot for riders wanting highway speed, passenger carrying, long-distance comfort, or any kind of touring capability.

Rider Fit Visualizer

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

Feet:

At 810mm, a rider of 68.9" with a 31" (estimated) inseam will reach the ground with both feet flat on the 2002 Beta Alp 125, with a cramped knee angle of around 70 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.
