01. HIGH PERFORMANCE
Arguably the best combination of power and weight, the TE 250 engine is a longstanding favourite with enduro riders. While technological advancements mean the TE 250 features a pioneering fuel injection system, it remains a low maintenance workhorse of an engine. Additionally, the TE 250 engine has an advanced construction featuring shaft arrangements precisely positioned for greater mass centralisation, a counter balancer shaft reducing vibration and a twin-valve controlled power valve for smoother power delivery.
The 66.4 mm bore cylinder in the TE 250 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 an state-of-the-art, 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.
Designed for minimal weight, the die-cast crankcases on the TE 250 engine feature a thin-wall design. To centralise mass, the shaft arrangement has been precisely positioned to harness oscillating masses at the ideal centre of gravity. The counter balancer shaft is also specifically integrated, making for a compact design. Additionally, the water pump casing is designed to improve cooling by optimising the flow of coolant.
Tailored specifically for each model using an innovative 3D design process, the header pipe on the TE 300 offers an advanced geometry and performance. This allows for improved ground clearance, while a corrugated surface makes the header pipe resistant to impact out on the trail. The muffler also features an aluminium mounting bracket and advanced internal construction for excellent noise damping and weight saving.
02. STATE-OF-THE-ART CHASSIS
The chromium molybdenum steel frame is expertly crafted using laser-cut, robot-welded, hydro-formed tubes, ensuring the highest level of precision and quality. The specifically crafted geometry utilises advanced longitudinal and torsional flex characteristics, for unparalleled rider feedback, energy absorption and exceptional straight-line stability. The cylinder head mountings are made of forged aluminium, improving handling and comfort. The premium grey powder coated frame features standard frame protectors, providing extra durability.
COMPOSITE CARBON FIBRE SUBFRAME
The carbon composite subframe is unique to Husqvarna Motorcycles and showcases advanced production technology and innovation. Using 70% polyamide and 30% carbon fibre, the 2-piece subframe has a total weight of just over 1 kg. With the help of computational dynamics, specific rigidity was engineered into the light and robust subframe, delivering outstanding handling and rider comfort.
OIL TANK AND PUMP
An electronic oil pump feeds vital 2-stroke oil into the engine. It is located just below the oil tank and feeds the oil via the throttle body, meaning the oil is only mixed with air at this stage. The pump is controlled by the EMS and delivers the optimal amount of oil according to the current RPM and engine load. The oil tank 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 when the tank needs refilling.
INTEGRATED COOLING AND RADIATORS
The radiators are expertly crafted using high-strength aluminium with CFD (computational fluid dynamics) to channel air through the radiators more efficiently. The cooling system is intelligently integrated into the frame, eliminating the need for additional hoses. The large centre tube running through the frame reduces pressure at this point, allowing for a consistent coolant flow. Additionally, the radiators are mounted close to the centre of gravity for improved handling agility. An optional radiator fan can be fitted and is available in the Husqvarna accessories catalogue.
03. RACE-WINNING SETUP
WP XPLOR FRONT FORK
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. The standard preload adjusters allow for easier adjustment without the use of tools. The fork's mid-valve piston delivers consistent damping, while the setting allows the fork to operate higher in the stroke for exceptional rider feedback and bottoming resistance. A new oil bypass in the outer tube reduces friction for a smoother, consistent travel through the stroke and a revised cartridge joint offers added damping performance.
WR XACT REAR SHOCK
The WP XACT shock provides advanced damping characteristics to the range. New valve seals with reduced hardness offer improved shock feedback. 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 sits low 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.
The highest level of quality is guaranteed with the new BRAKTEC braking system, offering the highest level of braking performance while being specifically tailored for enduro riding and delivering a sensitive and modulated feel. GSK wave disks (260 mm disc front and 220 mm rear) complete the high-quality braking package for complete confidence.
The new high quality BRAKTEC clutch system guarantees even wear, reliable and near maintenance-free operation as well as perfect modulation in every condition. Meaning that play is constantly compensated so that the pressure point and function of the clutch remain identical in cold or hot conditions, as well as over time.
The TE 250 features a bodywork which clearly showcases Husqvarna Motorcycles' progressive approach to offroad motorcycles while the Swedish inspired dark blue and electric yellow graphics create a distinctive look. The ergonomics are specifically tailored to deliver great comfort and control. As a result of extensive testing, the slim contact points make shifting between riding positions easier and allow the rider to flow with movement. The flat seat profile, together with the seat cover texture, deliver superior comfort and control in all conditions.
04. PREMIUM TECHNOLOGY
By using the MAP SELECT SWITCH, the engine characteristics can be tailored to modify the power delivery according to rider preference, conditions and terrain. It has two settings which can be toggled on the fly, namely, Map 1, for standard and full power and Map 2, for softer power and delayed ignition timing for terrain with less traction.
The TE 250 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 the handlebar throttle assembly. 2-stroke oil is mixed with the air and enters 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.
ELECTRIC START AND WIRING HARNESS
All TE models come standard with an electric starter. The system uses a compact and lightweight Li-Ion battery which is 1 kg lighter than a conventional battery. With several years of experience of developing and perfecting electric starting, the proven reliability on the Husqvarna enduro range is second to none, ensuring a quick and seamless start in any condition. Additionally, the wiring harness concentrates all needed electrical components into a common area below the seat for easy accessibility.
ENGINE MANAGEMENT SYSTEM
The TE 250 features an electronic control unit (ECU) which is responsible for a number of functions. The unit determines the ignition timing, the amount of fuel & oil injected into the cylinder and additionally, translates the information received from various sensors to adapt values and make corrections for automatic temperature and altitude compensation. This means the engine always runs at the optimum fuel/air mixture at any altitude.
