2023 GASGAS EX 250 for Sale

Electronics

• ENGINE MANAGEMENT SYSTEM - EMS: On the EX 250 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 250 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.

Handling

• FRAME: If you're going to race in the woods, you need to be tough! We build our frames to be tough using lightweight, laser-cut chromium molybdenum steel, which is robot welded for complete accuracy. We also ensure riders have complete confidence crossing tree roots and rocks thanks to specifically engineered flex. Together with proven geometry, our frames deliver playful handling and the very best stability and are finished with a durable, red powder coating.
• SUBFRAME: With a short and compact profile all GASGAS cross country subframes are made from lightweight aluminum. The profile helps centralize mass while also keeping weight down.
• FORGED TRIPLE CLAMPS: Our triple clamps offer 4-way handlebar adjustment, which ensures riders of all sizes can accurately set the handlebars to best suit their needs. Featuring a 22mm offset the forged triple claps also ensure maximum stiffness for precise handling and front suspension action.
• WP FORKS: Set-up for woods competition, all GASGAS cross country bikes comes fitted with 48mm WP XACT front forks with AER technology, providing incredible front-end damping for complete rider control. Firm enough to consistently handle high-speed bumps while also supple enough to ensure outstanding comfort across rough, broken edged terrain, they feature easy access clicker dials for quick adjustments and perfect rider set-up. Effective internal wizardry ensures consistent damping no matter how rough the terrain.
• WP SHOCK: Matched to the linkage system fitted to all GASGAS cross country bikes, the WP XACT rear shock deliver 300mm of rear wheel travel to ensure awesome handling, the very best traction and maximum fun in the woods. With specific internal settings giving riders complete confidence across a wide-range of offroad terrains, in offering full rebound and high/low-speed compression adjustability the shock can easily be fine-tuned to meet the needs of beginners and seasoned racers alike.
• SWINGARM: Exceptional strength at the lowest possible weight, and with visible chain adjuster marks to make chain adjustment quick and accurate. Our hollow, die-cast swingarms deliver durability and precision.

Motor

• MOTOR: The 6-speed EX 250 features a high-performance offroad motor that in the hands of an expert racer can be used to power the bike up and across terrain few would imagine passable. The perfect bike for 2-stroke fun, it's lightweight construction, twin-valve controlled power valve, true cross country specific transmission ratios and vibration reducing balancer shaft combine to give the much loved 2-stroke a competitive edge. Keeping life easy, our innovative fuel injection system does away with the need for time consuming jetting changes while also reducing fuel consumption and emissions.
• OIL TANK & PUMP: There's no need for pre-mixing fuel with the super-convenient EX 250! Instead, the bike features an electronic oil pump that feeds 2-stroke oil into the motor, keeping it lubricated via the throttle body. Using engine speed and throttle position sensor data, the engine management systems's precise control of the oil pump delivers the perfect amount of oil for any given conditions. The result? Reduced emissions by up to 50 per cent compared to a conventional pre-mix lubricated engine. The EX 250 maintains an average fuel-to-oil ratio of 80:1, which means one tank full of oil is enough for at least five tanks of fuel. Result!
• CYLINDER & PISTON: The 66,4mm bore EX 250 cylinder features a Twin-Valve Controlled (TVC) power valve system, which delivers smooth and controlled power throughout the RPM range. Optimal exhaust port timing is achieved with the combination of the state-of-the-art, adjustable power valve drive and a machined exhaust port window. Additionally, the cylinder features two inlet positions located on the transfer ports at the rear of the cylinder where a pair of fuel injectors are mounted. Deliver the fuel downwards into the transfer port these injectors guarantee perfect atomization with the air travelling upward to the combustion chamber. This ensures a more efficient combustion resulting in reduced fuel consumption and emissions. We match a lightweight piston to the EX 250 cylinder to ensure the highest levels of reliability and performance. It's as simple as that!
• COUNTER BALANCER SHAFT: Reducing rider fatigue by significantly decreasing motor vibrations the EX 250 houses a laterally mounted counter balance shaft, which ensures fun, enjoyable days in the saddle.
• TRANSMISSION: We use a forged 6-speed Pankl Racing Systems transmission that features specific cross country gearing in our EX 250, ensuring durability and reliability as well as ensuring riders can tackle high-speed fields and tight, technical woods. Additionally, an innovative shift lever reduces dirt build up guaranteeing easy operation in all conditions.
• CRANKSHAFT: The EX 250 crankshaft features a 66,4mm stroke and is balanced in conjunction with the counter balancer shaft for minimum motor vibrations. By incorporating a heavier ignition rotor, the crankshaft produces more inertia for a smooth, cross country specific power delivery.
• CRANKCASE: To us they are designed to centralize oscillating masses. All any rider needs to know is that our crankcases help make the EX 250 super-agile and easy to weave in and out of trees! Lightweight and die-cast, as well as being built to house internal shafts in the ideal position, they include a counter balancer shaft to keep the motor smooth. They're also seriously strong!
• EXHAUST SYSTEM: Ensuring cross country specific power, our EX exhaust systems are designed to deliver the highest possible quality. Comfortably meeting all FIM sound regulations, The EX 250 header pipe is produced with an innovative 3D stamping process to offer optimal geometry, performance and ground clearance, making it less susceptible to damage. The EX 250 muffler also features an advanced internal construction for excellent noise damping and weight saving.
• DDS CLUTCH: To ensure a super light and consistent clutch action we fit a Damped Diaphragm Steel (DDS) clutch and Brembo hydraulic system to our GASGAS EX 250. Using a single diaphragm spring instead of the more common coil spring, the design also incorporates a damping system, which increases both traction and durability. Additionally, the light and robust basket and inner hub guarantee optimal oil supply and cooling to the clutch. It's almost maintenance free, too!
