The EC 300 motor sets the benchmark for unrivalled power and lightweight construction. A 6-speed, fuel injected work horse, with a twin-valve controlled power valve, enduro specific transmission ratios and a vibration reducing balancer shaft, it is the perfect high-performance 2-stroke. 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 AND PUMP
There’s no need for pre-mixing fuel with the EC 300! 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’s precise electronic control of the oil pump ensures the perfect amount of oil for any given conditions, reducing exhaust smoke by up to 50 per cent compared with conventional pre-mix lubrication. The advanced lubrication system maintains an average fuel-to-oil ratio of 1:80, which means one tank full of oil is enough for at least five tanks of fuel. Result!
CYLINDER AND PISTON
The EC 300 cylinder is super-efficient and features two inlet positions on the transfer ports at the rear of the cylinder. Here, two fuel injectors deliver fuel downwards into the transfer port guaranteeing perfect atomization before the air then travels upward to the combustion chamber. This reduces fuel consumption and emissions. The 72mm cylinder also 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. We match a lightweight piston to the EC 300 cylinder to ensure the highest levels of reliability and performance. It’s as simple as that!
COUNTER BALANCER SHAFT
Significantly decreasing motor vibrations to reduce rider fatigue, the EC 300 houses a laterally mounted counter balance shaft, which ensures fun, enjoyable days in the saddle.
Guaranteeing durability and reliability, the EC 300 uses an enduro specific 6-speed transmission from Pankl Racing Systems to give riders a perfect spread of gears, ensuring they can tackle every kind of trail and terrain. An innovative shift lever design reduces dirt build up ensuring easy operation in all conditions.
By using a heavier ignition rotor in the EC 300 our crankshaft produces more inertia for a smooth, enduro specific power delivery. The crankshaft, which has a 72mm stroke, is balanced in conjunction with the counter balancer shaft for minimum motor vibrations.
Lightweight and strong, our die-cast crankcases house all internal shafts in the ideal position on the EC 300 and include a counter balancer shaft, to keep the motor smooth. By keeping all shafts close together the design centralizes oscillating masses, which ensures a bike that is super-agile and easy to weave in and out of trees! Additionally, the water pump casing is designed for effective cooling by optimizing the flow of coolant.
Ensuring enduro specific power across the full GASGAS enduro range, all our exhausts are designed and built to meet FIM sound regulations! Our 2-stroke header pipes are super strong and offer optimal geometry, performance and ground clearance, making them less susceptible to damage. The 2-stroke mufflers also feature an advanced internal construction for excellent noise damping and weight saving.
To ensure a consistent clutch action and a super light feel at the lever, the GASGAS EC 300 if fitted with a Damped Diaphragm Steel (DDS) clutch and a Braktec hydraulic clutch system. 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!
Providing superior stopping power while giving riders control and confidence, we fit Braktec braking systems to all of our enduro bikes. With a smooth, sensitive action the front brake features an 11mm piston within the master cylinder and 2x25mm pistons in the caliper, together with a waved 260mm front disc. The rear brake has a 12.7mm master cylinder piston and a 1x25mm piston caliper and uses a 220mm rear brake disc. Keeping weight to a minimum and offering complete confidence Braktec brakes ensure serious stopping power!
BRAKTEC HYDRAULIC CLUTCH
The Braktec hydraulic clutch system we fit to all GASGAS enduro bikes provides even wear, near maintenance-free operation and perfect action in all conditions. It’s also extremely light. Free play is constantly adjusted to ensure a biting point and action that never changes.
INTEGRATED COOLING SYSTEM AND RADIATORS
A cool running motor is a well performing motor, which is why all GASGAS enduro bikes feature an integrated cooling system that ensures maximum cooling efficiency. It also eliminates the need for additional hoses while the slim design of the radiators ensures a narrower bike with class-leading ergonomics. Expertly crafted using high strength aluminum, all radiators also give our enduro bikes a low center of gravity for best possible handling.
No matter if axle deep in mud, bouncing over rocky trails or being put through their paces over sandy, whooped out straightaways, our silver, alloy wheels are super high-strength. Featuring CNC machined hubs that use lightweight spokes and silver anodized aluminum nipples, GASGAS enduro wheels combine minimal weight with maximum stability.
All GASGAS Enduro bikes come fitted Maxxis Maxx Enduro medium tires as standard, designed to be durable, grippy and deliver the performance that completes our proven performance bikes. Inspiring confidence across a wide range of terrain, the tread pattern is designed to maximize both traction and braking performance.
ENGINE MANAGEMENT SYSTEM
Like having a team of scientists and data analysts working for you! Constantly measuring, calculating, optimizing and adjusting, our modern Engine Management System (EMS) makes riding and racing the EC 300 so, so straightforward. It also removes the need for fiddly, time consuming jetting changes. With an Electronic Control Unit (ECU) updated with the latest digital mappings for enhanced performance and power delivery, it controls the ignition timing and the amount of fuel injected, using sensor data such as intake air pressure, throttle position and coolant temperature.
Things are a little more involved on the 39mm Dellorto throttle body on our 2-stroke bikes, where a Throttle Position Sensor (TPS) relays airflow data to the ECU, which in turn calculates the amount of oil and fuel delivered to the engine! The end result on all bikes is crisp, clean running motors that deliver smooth, strong power.
ELECTRIC START AND LI-ION BATTERY
The best invention since the wheel! With an electric starter fitted to all of our 4-stroke and 2-stroke enduro bikes we can ensure that all GASGAS enduro models start super easily, no matter the weather. Using a Li-Ion battery, which weighs approx. 1kg less than a conventional lead battery, we can offer the convenience of electric starting while also keeping overall bike weight to a minimum. It’s a win, win for everyone!
