2021 HUSQVARNA FX450

2021 Husqvarna TX450.

The SOHC cylinder head is incredibly compact and lightweight using a short profile with the camshaft located as close to the center of gravity as possible, significantly improving handling and agility. The lightweight valves are actuated via a rocker arm and feature timing specifically designed to deliver precise levels of torque and throttle response.

The FX450 features a compact and lightweight SOHC cylinder head. As a result of the compact design the camshaft is closer to the center of gravity, significantly improving handling. Additionally, short valve timing offers progressive bottom-end performance and responsiveness. The camshaft features an optimal cam surface and actuates four lightweight titanium valves. The diameter of the intake valves is 40mm, with the exhaust valves being 33mm in diameter. Low-friction DLC coating on the rocker arm and low-friction chain guides offer optimum efficiency and reliability.

The FX350 and FX450 feature a 44mm Keihin throttle body. The injector is positioned to offer the most efficient flow into the combustion chamber. To ensure optimal throttle response the throttle cable is mounted directly and without a throttle linkage. This set-up provides immediate throttle response and feeling.

2021 Husqvarna TX450 is blessed with new maps that make power very smoothand manageable, even though it is the FC450 motocross powerplant.

The inertia produced by the crankshaft has been carefully calculated to deliver optimal traction and rideability from the powerful 450 cc plant. The crankshaft is specifically positioned to harness the rotating mass in the ideal center of gravity, with the end result being a lightweight and agile handling feel. A plain big-end bearing comprised of two force-fitted bearing shells ensures maximum reliability and durability, while also guaranteeing a long service intervals of 100 hours.

Magura hydraulic clutch is an extremely reliable, high-quality, German-made component that guarantees even wear, near maintenance-free operation and perfect action in every condition. Clutch 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. Additionally, the Magura brakes offer a high level of braking performance while being specifically tailored for cross-country. The 260mm front and 220mm rear rotor are by GSK.

2021 HUSQVARNA FX350

2021 Husqvarna TX350.

The 350cc DOHC engine weighs in at only 59.9 pounds and has a maximum power output of 58 hp. The engine is designed with performance, weight and mass centralization as its key criteria. As a result, all shaft arrangements have been positioned to allow oscillating masses to occupy the ideal center of gravity while all parts are engineered to offer the best possible performance while adding the least possible weight.

Produced by Pankl Racing Systems, the compact six-speed gearbox features a low-friction coating on the its fork that makes shifting smooth and precise. The gear lever features a design that prevents dirt build-up and ensures easy operation in the toughest conditions. An advanced gear sensor allows for specific engine maps in each gear.

The FX350 features a DS (Diaphragm Steel) clutch. The exclusive characteristics of this system include a single diaphragm steel pressure plate instead of traditional coil springs. The clutch basket is a single-piece CNC-machined steel component that allows the use of thin steel liners and contributes to the compact design of the engine.

2021 Husqvarna TX350 shares its engine and transmission with the FC350 motocross bike, but the suspension valving,  fuel tank and 18-inch wheel are all off-road accoutrements.

The WP Xact 48mm split air fork features a capsuled air spring and pressurized oil chamber for progressive and consistent damping. Extended oil and air bypasses reduce pressure peaks for more consistent damping. In combination with a new mid-valve damping system, the fork provides exceptional feedback and rider comfort. The setting is easily adjusted via the single air pressure valve, as well as easy, had-operated compression and rebound clickers. The air pump needed to adjust the air pressure in the fork is provided as standard equipment.

The map switch al both the FX350 and FX450 activates launch control, selects between two engine maps and engages traction control off of the same multi-switch. Both traction control and launch control offer optimal traction off the start and on slick tracks and the two systems work simultaneously.

2021 HUSQVARNA TX300i

2021 Husqvarna TX300i.

The TX300i signifies the constant development and secure future of the historic 300cc 2-stroke in the Husqvarna off-road line-up. Featuring the latest technology, the TX300i is a purpose-built closed course racing two-stroke with off-road specific features. A larger fuel tank, an 18-inch rear wheel and a side-stand increase the usability of the TX for its intended purpose. Additionally, the lightweight two-stroke engine is efficienct using modern electronic fuel injection, centralizes mass and features very little vibration thanks to a counter balancer shaft. As a result the TX300i offers a refined and manageable closed course racing package.

The TX 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 & smoother power delivery giving the loved 2-stroke the edge.

The compact cylinder features a 72-mm bore and refined port timings and the aid of a sophisticated power valve providing smooth and controllable power characteristics. With the addition of EFI, the cylinder features two lateral domes which hold the fuel injectors that supply fuel to the rear transfer ports. The downstream injection guarantees excellent atomization of the fuel with the upstreaming air, minimizing the loss of unburnt fuel and resulting in less emissions, a more efficient combustion and reduced fuel consumption.

2021 Husqvarna TX300i—the “i” stand for fuel-injected.

The electronic fuel injected engine is fitted with a redesigned 39mm throttle body made by Dell`Orto. The airflow is regulated by a butterfly connected with a twin-cable throttle cam, which is operated by the handlebar throttle assembly. A throttle position sensor provides airflow data to the control unit. Oil supplied by the electronically controlled oil pump via an oil intake tube is mixed with the incoming air to lubricate the moving engine parts.

The Keihin EMS features an electronic control unit (ECU) which is responsible for ignition timing, the amount of fuel & oil injected , throttle position sensor, ambient air & intake pressure, crankcase pressure and water temperature.

The hydro-formed, laser-cut and robot-welded frame is expertly crafted. Constructed with specifically calculated parameters of longitudinal and torsional flex, the frames feature optimal rigidity. That results in advanced rider feedback, energy absorption and stability. The frame is finished off in a premium blue powder coating and standard frame protectors that guarantee superior protection and durability.
