Playful. Energetic. Lightweight. Agile. The EX 300 is our do-it-all 2-stroke cross-country bike that delivers enjoyment and reliability while keeping maintenance costs low. A super-easy bike to use, and start, with no need for premixing fuel or tedious jetting changes, the innovative electronic fuel injection system allows for true 'gas-and-go' riding simplicity. With significantly reduced emissions and extended fuel range, there's so much to like about the EX 300.

• ENGINE MANAGEMENT SYSTEM - EMS: On the EX 300 the EMS features an electronic control unit (ECU) that is responsible for determining ignition timing and the amount of fuel & oil that is injected. Additionally, it receives information from the throttle position sensor, ambient air and intake pressure sensors as well as crankcase pressure and water temperature sensors and makes corrections for automatic temperature and altitude compensation. What that means in layman's terms is that riders don't need to make jetting changes!
• THROTTLE BODY: Our 2-stroke cross country bike uses 39mm Dellorto throttle body , ensuring precision, smooth action and high-performance. On the EX 300 the 39mm throttle body regulates the amount of air entering the engine via a butterfly valve, which is operated by dual throttle cables connected to the handlebar throttle assembly.
• ELECTRIC START AND LI-ION BATTERY: All GASGAS EX models are fitted with an E-starter, guaranteeing the one thing all cross country riders and racers want, super easy electric starting! A Li-Ion 2.0 Ah battery, which weighs approx. 1kg less than a conventional lead battery, ensures bikes conveniently fire into life each and every time while keeping overall weight down. No matter if riding conditions are super cold, or a bike has got super hot, all of our cross country models guarantee reliable starting.
