2011 GAS GAS EC250 4 stroke, We here at Alpine Motorsports love this bike. The low end power from its Yamaha 250f power plant makes it easy to get over or around obstacles without the high reving associated with many two strokes. Since it s a Yamaha engine, regular maintenance isn't the headache you may find yourself it with other European four strokes. Much like the rest of the Gas Gas fleet, the 4T offers a Marzocchi front fork and Ohlins rear shock absorber that combine with the geometry of the Gas Gas frame design makes for a comfortable and great handling machine. Additionally this bike includes all the wiring to add turn signals, speedometer and brake light.
