MOTOR

MOTOR

MOTOR

The DOHC 350cc motor might shares much of its design with the EX 250F motor but looks can be deceiving! Providing a significant increase in power and torque, the compact 4-stroke motor has a 450-rivalling power to weight ratio making it a strong and serious cross country racer. Compact and light, weighting just 27.2 kg the motor helps give our mid-sized cross country bike a lightweight, easy going character.

CYLINDER HEAD AND BALANCER SHAFT

The EX 350F features an advanced DOHC cylinder head layout that is meticulously engineered to deliver performance and reliability. Internally, the DOHC layout features polished camshafts and low-friction DLC coated finger followers, which ensure zero friction and faultless operation. Together with the lightweight valves - 36.3mm intake and 29.1mm exhaust - they deliver awesome performance. In order to counteract the rotational force of the crankshaft and reduce vibration, the EX 350F engine uses a multifunctional counter balancer shaft, which also drives the water pump and timing chain.

CYLINDER & PISTON

A large diameter, lightweight forged bridged-box-type CP piston sits inside the 88mm bore, 57.5mm stroke cylinder, pumping out the power that makes the EX 350F the seriously capable cross country racer that it is. The piston crown geometry is perfectly matched to the high-compression combustion chamber and as a result, the low oscillating mass delivers exceptional power, high revs and a broad, user friendly power band.

TRANSMISSION

Allowing riders to maximize the full potential of the awesome EX 350F, the bike is fitted with a 6-speed forged transmission from Pankl Racing Systems. Ensuring the highest quality, durability and reliability, a wide-ratio transmission is used, which is specifically suited to cross country riding and racing. Additionally, a gear sensor allows the EMS to tailor a specific engine character suited for each gear

CRANKSHAFT

Rarely seen but always working! The crankshaft fitted inside the EX 350F is key to driving the extremely high-speed moving parts inside the engine, which in turn unleash the unrivalled power achieved by the 350cc engine. Additionally, thanks to an oil feed that brings enhanced engine durability, the EX 350F enjoys long, 135-hour crankshaft service intervals, which save time, effort and cost.

CRANKCASE

The EX 350F engine is designed to be compact while centralizing rotating masses, which means all internal moving shafts and parts are carefully positioned at the ideal center of gravity. As a result, riders can enjoy the best possible handling. Our high-pressure die cast production process guarantees minimal weight while maintaining strength.

EXHAUST SYSTEM

Ensuring cross country specific power, our EX exhaust systems are designed to deliver the highest possible quality. The EX 250F, EX 350F and EX 450F exhaust systems are designed using an innovative 3D hydroforming process to ensure the best performance and lowest weight as well as a 2-part header pipe, which 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.

DS CLUTCH

Fitted with a Diaphragm Steel (DS) clutch ensures riders can quickly and easily keep the revs up on the EX 350F. Featuring a single diaphragm steel pressure plate instead of traditional coil springs the clutch basket is a single-piece CNC machined steel component, which allows the use of thin steel liners. Light and precise the clutch ensures a smooth and constant action no matter how much abuse it receives!
