Grips and throttle assembly
The ODI lock-on grip on the left side requires no gluing, while on the right, the vulcanised grip features an innovative integrated throttle mechanism. The assembly has easy free-play adjustment and, by changing a cam, throttle progression can be altered.
➢ Throttle assembly and ODI grips → easily alter throttle progression; easy grip mounting without glue
Map switch, traction control
Designed for easy operation, the standard map switch on off-road FE models selects between 2 EFI maps and activates the traction control. Traction control features an updated setting offering improved traction and control on slick terrain.
Traction control is selected to an on or off position from the switch and functions by analyzing throttle input from the rider and the rate at which RPM increases in the engine. If the RPM increases too quickly, the EMS registers a loss of grip and reduces the amount of power to the rear wheel ensuring maximum traction.
Additionally, all 2-strokes are also fitted with a standard map switch allowing selection between 2 ignition curves based on conditions or rider preference.
➢ Standard handlebar map switch (not on dual-sport) → alter engine characteristics according to conditions and rider preference
➢ Traction control → optimal traction in all conditions
Engine Management System (EMS)
Apart from controlling EFI parameters on the 4-strokes, the Keihin EMS features selectable engine maps on the off-road FE models via the switch on the handlebar, as well as traction control. Combined with the gear sensor, power delivery is tailored for each gear.
➢ Keihin EMS → smaller, lighter and faster at processing engine data for more efficient engine management
➢ Gear sensor → specific engine maps for each gear
On the 2-strokes, the EMS features an electronic control unit (ECU) which is responsible for a number of functions. The unit determines the ignition timing, the amount of fuel and oil injected and additionally receives information from the throttle position sensor, ambient air and intake pressure sensors as well as crankcase pressure and water temperature sensors to adapt values and make corrections for automatic temperature and altitude compensation eliminating the need to change carburetor jetting as in the past.
➢ 2-stroke EMS → modern engine management eliminating the need for jetting changes
Throttle body
The 4-stroke range features a 42 mm Keihin throttle body. The injector is positioned to ensure the most efficient flow into the combustion chamber. To ensure optimal throttle response the throttle cable is mounted directly without a throttle linkage, to provide more immediate throttle response and feeling.
➢ Throttle body → 42 mm, injector positioned for optimal flow, more immediate throttle response thanks to direct cable mounting
The 2-strokes use a 39 mm throttle body, which regulates the amount of air entering the engine via a butterfly valve operated by dual throttle cables connected to the 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 and 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.
➢ 39 mm throttle body → regulates air flow, TPS relays airflow data
Exhaust system
Tailored specifically for each model using an innovative 3D design process, the 2-stroke header pipes feature advanced geometry and performance. The TE 250i/300i header pipe offers more ground clearance making it less susceptible to damage while a corrugated surface makes the header pipe more durable to damage from rocks and other hazards found on the trail. The 2-stroke mufflers also feature an aluminum mounting bracket and advanced internal construction for excellent noise damping and weight saving.
The 4-stroke exhaust system is expertly designed to deliver class-leading performance at the lowest possible weight. The header pipe is designed and manufactured in two pieces, to be as compact as possible. The joining position allows it to be removed without having to take out the rear shock. Further innovation allows for a short, compact silencer without increasing noise levels. The component is crafted from lightweight aluminum and is stylishly finished off in a black coating that highlights its premium quality.
➢ Corrugated surface on TE 250i/300i → more durable against damage
➢ Header joining position on 4-stroke → removable without detaching rear shock
Electric start and wiring harness
All TE and FE models come standard with an electric starter. The system uses a compact and light-weight Li-Ion battery, which is 2.2 lbs (1 kg) lighter than a conventional battery. With several years of experience of electric starters on Husqvarna Motorcycles’ off-road and dual-sport models, the proven reliability is second to none, ensuring a quick and seamless start in all conditions.
Additionally, the wiring harness concentrates all needed electrical components into a common area below the seat for easy accessibility.
Integrated cooling system and radiators
The radiators are expertly crafted using high-strength aluminum 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 center tube running through the frame reduces pressure at this point, allowing for a consistent coolant flow.
Additionally, the radiators are mounted close to the center of gravity for improved handling agility.
All 4-stroke models are fitted with radiator fans as standard. For the 2-stroke models, radiator fans are optional and available in the Accessories catalogue.
➢ Integrated cooling → maximum efficiency in minimum space
➢ Large central tube → consistent coolant flow
Fuel tank
The polythene fuel tanks incorporate a quick release filler cap and an integrated fuel pump. The fuel pump features internal line routing directly from the pump to the flange for optimal fuel flow. Additionally, the external fuel line is specifically positioned to make it less exposed and susceptible to damage. A fuel level sensor is incorporated on all models.
Airbox and tool-less air filter access
The airbox is designed with precisely positioned inlet ducts aimed at preventing air deformation to ensure maximum airflow and maximum filter protection.

The nipples incorporate an advanced design reducing the frequency of spoke checks and maintenance. Dual-sport models feature GIANT rims paired with CNC machined hubs and aluminum nipples.
➢ Lightweight but strong and reliable construction → minimum unsprung weight
Tires
The off-road range features Dunlop AT81 tires, offering advanced grip in a wide variety of different terrain. The dual-sport models feature Continental TKC80 tires, providing excellent grip both on and off-road.
Bodywork
The off-road and dual-sport range features bodywork which clearly showcases Husqvarna Motorcycles’ progressive approach to offroad motorcycles while striking dark blue and electric yellow graphics stylishly adorn the Swedish inspired design. 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.
