2015 Husqvarna FC450 on Totalmotorcycle.com

Shock wave of power…

Strong, yet usable engine performance catapults the FC 450 into contention at the top of the 450 class. The FC 450 has astonishing force from the SOHC engine, incredible handling from the lightweight, cutting-edge chassis, and embodies the core values of Husqvarna. The standard electric start and handlebar-mounted map switch make the FC 450 one of the most advanced Motocross bikes on the market.

 

2015 Husqvarna FC450 Totalmotorcycle.com Features and Benefits

ENGINE

The compact SOHC design delivers exceptional power and torque over an extremely wide rev range. The accessible, class-leading performance of the FC 450 engine allows riders to confidently rocket of the corners, power down the straights and clear any jump. The single overhead cam in the cylinder head actuates four lightweight titanium valves, only 32 grams each, via lightweight and rigid rocker arms (DLC coated on the intake). The diameter of the intake valves is 38mm, while on the exhaust side it is 33mm. The broad power band of the FC 450 stretches to 11,500 rpm, peaking at 60 hp while maintaining exceptional torque low in the rev range. A three layer head gasket is used to guarantee durability. The handlebar mounted map switch is a standard feature and allows the rider to switch between maps while riding, adjusting power delivery and engine performance according to rider fatigue and track conditions.

ENGINE MANAGEMENT SYSTEM

The electronic fuel injection and 44mm throttle body of the Keihin Engine Management System on the 4-stroke models, combine to offer amazing power delivery and efficiency at all engine speeds. The injector was positioned on the bottom of the inlet tract for optimal air-fuel mixture, resulting in crisp throttle response and class-leading power. Great attention was dedicated to ensuring that cleaning and washing the bike will not damage the electronics. The wire harness, lead wire, and high quality sealed critical connectors ensure that a jet wash poses no threat. The throttle position sensor (TPS) is also water resistant and protected.

CRANKSHAFT, CONROD AND PISTON

The FC 450 features an industry-leading Pankl produced crankshaft and conrod in order to ensure that the high power output and torque of the 450cc engine are combined with durability and long service intervals (100 hours before changing con rod, con rod bearing and crank pin). To achieve this goal, the lightweight crankshaft has a pressure lubricated plain big end bearing, and two force-fitted shells that run directly on the crank pin. The König bridge-box-type piston weighs 330g and has a bore of 95mm, it was developed to reduce engine vibration and optimise strength. The compression ratio is 12.6:1 for an amazing peak output of 60 hp.

STARTER

All 4-strokes feature a reliable electric-start-only system. The electric starter is a great advantage in every situation, especially in the event of a fall or in a difficult location on track. The increase in weight has been kept to a minimum by eliminating the mounting and components of the kick-starter.

FRAME

The engineers in Research and Development had clear objectives in terms of torsional rigidity, longitudinal stiffness and weight. The goal was to give the rider optimal feedback and complete confidence in every situation. This was achieved by designing the lightweight chromium molybdenum frame with precise longitudinal flex that helps absorb impacts from the rear wheel, working together with the suspension for better comfort and greater feedback. The torsional rigidity enhances turn-in, sharp handling and stability even on the roughest terrain, giving the rider complete confidence in finding his lines and increasing his pace lap after lap. WP Performance Systems produces every frame to exacting standards in an ultra-advanced production plant. The production process involves hydro-forming and robot welding for maximum precision and consistent quality that is reflected in the supreme performance of every Husqvarna motorcycle.

SUBFRAME

The lightweight polyamide rear subframe has been reinforced with an additional screw on the airbox side that improves the fitment between the left subframe arm and the airbox. The improved seal guarantees better performance and durability. The three-piece composite subframe, made of high strength polyamide with a precision injection moulded production process, has been designed to offer stiffness while flexing more than an aluminium subframe, complementing the flex characteristics of the frame in order to offer optimum rider feedback and feeling in all conditions. The lightweight design offers engineers unlimited opportunities in integrating features such as all the electronics and the airbox.

SWINGARM

The single component construction of the aluminium swingarm eliminates welding, providing more reliability, stability and safety, as well as superior quality and consistent behaviour over time compared to other construction processes. The specific flex engineered into the swingarm makes the most of the Husqvarna engine characteristics in terms of traction and power.

TYRES

The lightweight wheels are complemented by new Dunlop MX52 Motocross tyres that feature a new “block-within-a-block” design for more progressive cornering. The new Dunlop rubber has been developed to offer superior grip in a wider variety of terrain.

FRONT SUSPENSION

WP has developed a closed cartridge 4CS fork specifically for Motocross. The new four chamber fork has improved damping characteristics and is also lighter than the previous closed cartridge fork. As with all 4CS forks by WP, the clicker settings can be easily and quickly adjusted via the dials on the top of the fork tubes. The red dial on the right alters rebound damping, while the white dial on the left is for compression damping. WP suspension stands for top quality and offers the best performance levels. Precision engineering, quality materials and advanced production processes are an integral part of the WP forks on the Husqvarna model range.

REAR SHOCK

The high performance Husqvarna DCC (Dual Compression Control) rear shock made by WP has a revised setup and has been re-valved to match the geometry changes of the new rear link. The new shock features a 4mm increase in stroke thanks to the new link geometry, for better handling and damping characteristics.

REAR LINK

The rear link has been revised and now features a higher starting rate, and therefore a less progressive curve, that provides better control in all circumstances. Further advancements in production processes have seen an improvement in quality and a reduction in weight of the triangle and pull rod of approximately 40g.

22MM FRONT AXLE

In the overall optimisation of the chassis, the MY15 Motocross bikes feature a new 22mm front axle with specific fork shoes in place of the previous 26mm axle. The new axle is lighter, and the shoes have shorter offset and increased trail, for more stability and better front-end feel.

HANDLEBAR

New Neken handlebar, with the same bend as the previous model year, with Husqvarna bar pad mated to Husqvarna grips for excellent control of the bike.

FORK PROTECTORS

The distinctive yellow fork protectors have been redesigned and no longer wrap around the fork leg. The new design allows for improved access to the fork leg for better maintenance and cleaning, while also being easier to replace.

BRAKES

Exceptional stopping power is guaranteed by the latest generation Brembo brakes, featuring floating calipers in combination with 260mm wave discs at the front and 220mm wave discs at the rear. The perfectly placed controls allow for optimal feel and balance under extreme conditions.

SEAT

The seat features a new seat cover material that improves grip and durability. The sturdy material is also harder than the previous cover, making the entire seat firmer, improving comfort and feeling.
