CYLINDER HEAD

It's the magic that happens inside the DOHC cylinder head that guarantees the EC 250F produces efficient, high-level power across the entire rev range. Featuring large titanium valves and finger followers with a tough Diamond Like Coating (DLC) the high-revving cylinder head ensures minimum drag for maximum performance.

CYLINDER & PISTON

Both professionally engineered from high strength aluminum, the EC 250F cylinder and piston perform an important role in delivering the lively performance that makes the bike so much fun to ride. Guaranteeing outstanding performance and reliability the 78mm bore houses a rigid, forged bridged-box-type piston made by CP.

COUNTER BALANCER SHAFT

In order to counteract the rotational force of the crankshaft and reduce vibration, the EC 250F engine uses a multifunctional counter balancer shaft that also drives the water pump and timing chain.

TRANSMISSION

Gear changes, lots of gear changes, that is part of what makes riding and racing a 250cc 4-stroke fun. The EC 250F comes with an enduro specific, 6-speed forged transmission made by PANKL RACING SYSTEMS that ensures the highest durability and reliability. Additionally, a gear sensor allows the EMS to tailor a specific engine character suited for each gear.

CRANKSHAFT

Specifically positioned within the motor, the EC 250F crankshaft helps centralize oscillating masses for super easy handling. A plain big end bearing with force-fitted bearing shells increase service intervals, ensuring durability and the best possible performance. Plain big end bearings with force-fitted bearing shells ensure 135-hour service intervals!

CRANKCASE

The EC 250F motor is designed to house the motor’s internal shaft arrangements at the ideal center of gravity to improve overall handling. The casings, manufactured using a high-pressure die cast production process, integrate the oil supply to the main bearing and ensure minimal weight while retaining exceptional reliability and strength.

EXHAUST SYSTEM

Ensuring enduro specific power across the full GASGAS enduro range, all our exhausts are designed and built to meet FIM sound regulations! The 4-stroke exhaust systems are expertly designed to deliver the very best performance at the lowest possible weight while a joining position allows it to be removed without having to take out the rear shock. Further innovation allows for a short, compact silencer that doesn't increase noise levels. The muffler shell is crafted from lightweight aluminum.

DDS CLUTCH

Ensuring riders have precise control over the EC 250F we use a Dampened Diaphragm Steel (DDS) clutch. Using a single diaphragm steel pressure plate instead of traditional coil springs, together with a damping system the clutch delivers better traction and durability. We use a Braktec hydraulic master cylinder to ensure a smooth, progressive lever action.
