2022 Husqvarna TE300i

Engine
The 300cc 2-stroke engine is the benchmark in unrivalled power in a lightweight construction. The engine features precisely positioned shaft arrangements for optimal mass centralisation, a counter- balancer shaft reducing vibration, a twin-valve controlled power valve and 6-speed enduro gearbox.

The TE 300i features an advanced electronic fuel injection system. This comprises of a set of fuel injectors positioned at the transfer ports which deliver the ideal amount of fuel into the engine for every condition. This not only reduces fuel consumption and emissions but also delivers a clean and smooth power delivery giving the revered 2-stroke the edge.

Cylinder
The 72mm bore cylinder features a twin valve-controlled power valve system which delivers smooth and controlled power throughout the RPM range. Optimal exhaust port timing is achieved with the combination of a state-of-the-art, adjustable power valve drive and 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. The injectors deliver the fuel downwards into the transfer port which guarantees excellent atomisation with the air travelling upward to the combustion chamber. This ensures more efficient combustion resulting in reduced fuel consumption and emissions.

Piston
The lightweight piston is perfectly matched to the cylinder and transmits minimal oscillating mass ensuring high levels of reliability and performance.

Engine casings
The TE 300i engine is designed to improve mass centralisation. As a result, the lightweight, die-cast engine casings are developed to accommodate a shaft arrangement aimed at centralising oscillating mass and improving ride-ability. Additionally, the counter balancer shaft is integrated in a very compact manner having little effect on the overall design.​

Counter balancer shaft
The engine houses a laterally mounted counter balancer shaft. The balancer significantly reduces vibration resulting in a smoother and more comfortable ride.

Crankshaft
The crankshaft features a 72mm stroke and is balance in conjunction with the counter balancer shaft for minimum vibration. By incorporating a heavier ignition rotor, the crankshaft produces more inertia than its motocross counterpart which improves control in the lower RPM range.

Gearbox
A 6-speed PANKL gearbox features enduro specific ratios while an innovative shift lever reduces dirt build up guaranteeing easy operation in all conditions.

Clutch
The TE 300i features a DDS (damped diaphragm steel) clutch. What this means is the clutch uses a single diaphragm spring instead of the more common coil spring design resulting in a much lighter clutch action. This 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.

Combined with the BRAKTEC hydraulic system this guarantees a light, modulated clutch feel with reduced maintenance and freedom from adjustment.

Oil tank and pump
The TE 300i features an electronic oil pump which feeds vital 2-stroke oil into the engine to keep it lubricated. The pump is located just below the oil tank and feeds the oil via the throttle body meaning the oil is not mixed with the fuel, eliminating the need for pre-mixing as on traditional 2-stroke engines. The pump is controlled by the EMS and delivers the optimal amount of oil according to the current RPM and engine load reducing waste and preventing excessive smoke being transmitted from the exhaust.

The oil tank is located beneath the fuel tank and is connected to a filler hose which runs through the upper member of the frame to a filler cap conveniently located for easy refills. The tank capacity is 0.7 litre and is fitted with a sensor which illuminates a warning visible to the rider when the oil needs to be refilled.
