Engineered by Beta for the super motard motorcycle segment, the 2006 Beta M4 4T Supermotard utilizes a 349 cc (21.3 cu in) air-cooled single cylinder, four-stroke layout. Internal engine geometry specifies a bore and stroke of 79.0 x 71.2 mm (3.1 x 2.8 inches) with a 9.5:1 compression ratio.
On the scales, the M4 4T Supermotard measures 133 kg (293 lbs) dry. Rider ergonomics and chassis geometry center around a 920 mm (36.2 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,410 mm (55.5 in) wheelbase engineered for quick, flickable steering geometry. The 11.5-liter (3 US gal) fuel tank supports practical everyday commuting and weekend road stints.
