Tuned to best suit race-experienced riders, the 249 cm3 liquid-cooled, 4-stroke Single’s wide powerband focuses on high-rpm performance and extends way into the over-rev. Already featuring race-inspired tuning and parts like the high-performance piston with bridged-box bottom, the 2011 engine receives fuel injection and a number of changes for even more power, stronger low-mid range torque, more accurate shifting and a quieter exhaust note.

Designed specifically for motocrossers, the fuel injection system incorporates a small lightweight ECU and operates without a battery to further eliminate unnecessary weight. And of course, fuel injection eliminates the need to adjust engine settings to suit track and climate conditions.
