The 2010-11 SX 125 carries over the two-stroke supermotard formula with no change to its published specification: a liquid-cooled 125 cc reed-valve single with separate oil injection, six gears and around 22 hp. The steel double-cradle chassis, 40 mm upside-down fork with 260 mm of travel and 17-inch wheels give it proper supermoto handling for young riders on A1 licences.
