Rider Profile

Best ForBest suited to riders with at least some off-road or dual-sport experience, given the tall seat height and dirt-oriented ergonomics.
PurposeDesigned primarily for trail riding and dual-sport exploration rather than outright speed or highway cruising.
Rider FitThe tall 35.8 inch seat height and narrow perimeter-frame stance favor taller or more confident riders who can comfortably handle the bike standing or at a stop.
CharacterA light, single-cylinder trail bike with a lively, torquey feel and nimble handling suited to technical terrain and tight trails.
Not Ideal ForNot a good fit for riders wanting sustained high-speed highway touring or two-up comfort over long distances.

2007 Beta Alp 4.0 Rider Ergonomics Assessment

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

Feet:

At 865mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with tip-toe one foot on the 2007 Beta Alp 4.0, with a cramped knee angle of around 75 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.
