2017 Husqvarna FX 450 - First Look: 2017 Husqvarna Cross-Country/Off-Road Race Models - Motocross Pictures - Vital MX

Husqvarna’s new for 2017 FX 450 offers class leading performance in a lightweight, capable package. All aspects are designed to offer exceptional performance in conjunction with rider comfort and ergonomics making the FX 450 equally appealing to amateur and professional off-road riders alike. Traction control, map select and WP AER 48 forks are just a few of the standard features which ensure the FX 450 embodies premium quality and feel. Off-road specific features raise the FX 450 to the top of the class.

Engine

The SOHC engine is the perfect example of the advanced engineering techniques used by Husqvarna motorcycles offering a peak power of 63 hp at an overall weight of just 61.3 pounds.Mass-centralization is key in the engine design, enabling chassis engineers to position the engine closer to the center of gravity for greatly improved handling and maneuverability.

  • Mass centralization - improved handling and reliability.
  • Performance - 63hp and only 61.3lbs.

Cylinder head

The compact SOHC cylinder head has been designed to offer the maximum performance and the minimum possible weight. The camshaft actuates four lightweight titanium valves that weigh only 32g on the intake side and 28g on the exhaust. The diameter of the intake valves is 40mm, while on the exhaust it is 33mm. Low-friction DLC coating on the rocker arm and low-friction chain guides offer optimum efficiency and reliability.

  • SOHC - compact engine design.
  • Titanium valves - low weight, only 32g on intake and 28g on exhaust.
  • DLC coating & optimized chain guides - reduced friction.

Cylinder and piston

The lightweight aluminum cylinder is an engineering masterpiece. Featuring a 95mm bore and a CP bridge-box-type piston which weighs only 320g. The compression ratio is 12.6:1 for an amazing peak output of 63hp.

  • Lightweight aluminum cylinder - 95mm bore.
  • Lightweight CP forged bridged-box-type piston - high performance, reduced oscillating masses.

Crankshaft

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

  • Crankshaft position - ideal center of gravity, improved handling.
  • Plain big end bearing and force-fitted bearing shells - increased durability and service intervals.

Crankcases

The crankcases have been designed to house the shaft arrangements and internals of the engine in the position that offers the best possible handling. Additionally, the position of the clutch shaft keeps the clutch above the oil level resulting in decreased friction and increased efficiency.

High-pressure die cast production processes keep the overall weight to a minimum, resulting in thin wall thickness while retaining reliability. The historical Husqvarna logo adorns the bronze finished crankcase covers.

  • Design - optimized mass-centralization, increased efficiency.
  • High pressure die cast production process - thin walls for reduced weight, while maintaining strength.

Gearbox

The new 5-speed gearbox has a low-friction coating on the shifting fork guaranteeing smooth and precise shifting. The gear lever features a design that prevents dirt build-up and keeps the lever tip in its original position even in the toughest conditions. An advanced gear sensor allows for specific engine maps in each gear.

  • 5-speed gearbox - smooth and precise shifting.
  • Integrated gear sensor - specific engine maps for each gear.

DDS clutch

The FX450 features a DDS (Dampened Diaphragm Steel) clutch as opposed to the CSS clutch found on the FX 350.

The exclusive characteristics of this system include a single diaphragm steel pressure plate instead of traditional coil springs. It integrates a damping system for better traction and durability. 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.

  • New DDS clutch - lighter with better modulation and improved durability.
  • Magura hydraulic system - perfect clutch modulation.

Off-Road Specific Equipment

A large 2.2 gallon fuel tank gives the FX 450 the extra range needed for longer loops. The rear wheel is an 18-inch unit with Dunlop AT 81 off-road tires front and rear. A side stand completes the off-road transformation of the FX 450.

Benefits

  • Most powerful Husqvarna off-road engine ever developed.
  • Intuitive and confidence-inspiring riding experience.
  • Advanced electronics include traction control,launch control and adjustable engine maps.
  • Exclusive DDS clutch with Magura hydraulics for smooth and light clutch action.
  • Electric starter and compact Li-Ion battery.
