At the heart of the 2007 KTM 50 Senior Adventure minibike, cross motorcycle, KTM utilizes a 49 cc (3 cu in) air-cooled single cylinder, two-stroke layout. Internal engine geometry specifies a bore and stroke of 39.5 x 40.0 mm (1.6 x 1.6 inches).
On the scales, the 50 Senior Adventure measures 38.4 kg (85 lbs) dry. Rider ergonomics and chassis geometry center around a 650 mm (25.6 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,030 mm (40.6 in) wheelbase engineered for quick, flickable steering geometry. The 2-liter (0.5 US gal) fuel tank supports practical everyday commuting and weekend road stints.
