The 300 cc 2-stroke engine in the TE 300i is the flagship of the Husqvarna Motorcycles enduro range. Featuring precisely positioned shaft arrangements for optimal mass centralisation, a counter balancer shaft reducing vibration, a twin-valve controlled power valve and electronic fuel injection, it is the benchmark when it comes to enduro performance.
The 72 mm bore cylinder in the TE 300i features a twin valve-controlled power valve system which delivers smooth and controlled power throughout the RPM range. Exhaust port timing has been improved with the combination of an optimised, adjustable power valve drive. The cylinder also features two inlet positions at the rear of the cylinder where a pair of fuel injectors are mounted. This ensures efficient combustion resulting in reduced fuel consumption and emissions.
The TE 300i uses a 39 mm throttle body which regulates the amount of air entering the engine via a butterfly operated by dual throttle cables connected to a new handlebar throttle assembly. Unlike 4-stroke throttle bodies, fuel is not introduced at this point but rather 2-stroke oil is mixed with the air entering the engine to lubricate the crankshaft, cylinder & piston.Additionally, 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 while a bypass screw regulates the idling speed and a cold start device opens a bypass providing more air for cold starts.
The TE 300i features an electronic oil pump which feeds vital 2-stroke oil into the engine . 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 as well as 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 tube of the frame to a filler cap conveniently located for easy refills. The tank capacity is 0.7 l and is connected to a low level sensor which illuminates notifying the rider when the tank needs refilling.
The WP Xplor 48 front fork is designed specifically for enduro riding. Its open cartridge layout has a spring in each leg with split damping functions. Compression damping in the left leg and rebound damping in the right. Adjustment is via easy-to-access clickers (30 clicks) on the top of each fork leg. For 2020, the standard preload adjusters allow for easier adjustment without the use of tools. The fork’s updated mid-valve piston delivers more consistent damping, while a new setting allows the fork to operate higher in the stroke for improved rider feedback and bottoming resistance.
Featuring a new main piston and updated base setting to match the new frame and front end, the WP XACT shock provides advanced damping characteristics to the new range. The compact and lightweight shock features a pressure balance inside, ensuring consistent damping and superior rider comfort. Using the same linkage progression found in the Husqvarna Motocross range, the rear end now sits lower, for improved control in extreme enduro conditions. The fully adjustable component delivers 300 mm rear wheel travel, as well as unrivalled traction, feeling and energy absorption.
