Positioned in KTM's atv motorcycle lineup, the 2012 KTM 505 SX pairs a 477.5 cc (29.1 cu in) liquid-cooled single cylinder, four-stroke architecture with road-focused gearing. Internal engine geometry specifies a bore and stroke of 100.0 x 60.8 mm (3.9 x 2.4 inches) with a 11.0:1 compression ratio.
On the scales, the 505 SX measures 173 kg (381 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 795 mm (31.3 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,280 mm (50.4 in) wheelbase engineered for quick, flickable steering geometry. The 13.4-liter (3.5 US gal) fuel tank supports practical everyday commuting and weekend road stints.
