Character	It has a laid-back, classic cruiser personality with modest single-cylinder power delivery and a relaxed, unhurried riding feel.
Not Ideal For	This bike is not for riders seeking high speed, off-road capability, or serious two-up touring comfort.

Units

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

Feet:

At 740mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2006 Beta Jonathan 350, 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.
