Husqvarna has updated their 2012 lineup with three new models – TC449, TC250 and CR65. Press releases from Husqvarna follow:
Husqvarna TC449: a different style
Running with the herd can be comforting but breaking out in new directions is more stimulating and fun. Husqvarna has always made its own road, innovating with new projects like the TC449 which break away from tradition and the banal. To distinguish yourself where performance alone is not enough and evoke passion in those who know that – in competition too – you need a certain style. Because when it comes to big machines, innovating does not mean raw power… but how to handle it. The new TC449 explores beyond the horizon, perfecting the concepts introduced last year: tank below the seat to improve the center of gravity, airbox high in the frame to take in fresh and clean air, and above all, the swing arm pivot coaxial with the gear box output shaft, reducing almost to zero the effects of chain drag. If eye candy doesn’t affect the stopwatch, it’s still a pleasure to know your bike is no ugly duckling. When biking is your true passion the goal is not the world championship, but the podium of your emotions. In the words of a master: which motocross bike did Steve McQueen ride? Husqvarna!
Massive horsepower needs careful handling. Best to let off steam on the track. Traction and maneuverability: these are the objectives of the TC449 and its revolutionary mechanical design. The tank has moved below the seat with the fuel cap to the rear and the air filter box is located directly behind the headstock, making the bike more balanced and a different shape, definitely more user friendly. The bodywork has integrated graphics (InMould technology) enhancing design and function, finally resolving the problem of adhesives that peel off under the power wash. Moreover, the graphic design on the new TC449 has been completely revised, and the aesthetic makeover extends to the frame, which is now black and the rims, now anodized silver.
The frame has also been changed at the steering-head area, reinforced with chrome-moly 25CrMo4 steel plates. The rear seat rail and engine supports have also been similarly strengthened. Given the improved rigidity of the frame, the preload of the Kayaba suspension was reset: the fork has a harder setting and the monoshock damps more slowly. It is softer at the start of the stroke, and has a new progressive spring.
To lighten and simplify the electrical system, the 2012 Husqvarna TC449 has had the entire wiring completely redesigned.
Engine: ignition to the future.
The ultra-modern twin cam four valve engine is fed by a Keihin electronic injection (46 mm throttle body), but that is not what is so special about it. The air intake path is much more linear than other bikes in the category, and allows impressive performance to be achieved easily. The dry sump crank-case utilises two lubrication pumps, intake and outlet; the sophistication of the engine can also be seen in the choice of bore/stroke ratio: 98 X 59.6 mm. It was decided to equip the TC449 with electric start, because anyone, even a champion, can lose precious seconds kick starting after a simple slide. Evolution never looks back, and even the modern mechanical design has been improved on the new 2012 TC449.
The radiators have been upgraded to improve the cooling efficiency, and the filter box breathes better thanks to a higher volume air intake. Engine performance has been raised by adjusting the valve timing and revising the two mappings for ignition/injection (now also selectable with the engine running). Mid range torque has been improved with a new intake manifold.
These changes do not affect the bike’s reliability. On the contrary, the 2012 version engine undoubtedly has a more durable crankshaft, with galvanizing and high-resistance DLC treatments of the piston rod and rod bearing.
New Husqvarna TC250
Husqvarna TC250: Developed at world championship level
The return of Husqvarna to the MX World Championship has already produced its first results. The experience gained at the World MX2 Championship has now been incorporated into the new Husqvarna 2012 model TC250. The collaboration between the factory R&D technicians and the Ricci Racing team led to the development of important updates, which bring the TC250 to the top of its category. Both to the engine – a real jewel at only 22 kg! – and the mechanical design, and all modifications which will be immediately appreciated by riders of every level and experience. Just try it.
The steel frame is made of tubing with a variety of cross sections, strengthened and made more rigid with new plates (chrome-moly 25CrMo4 steel) at the steering-head. Stability and maneuverability are noticeably improved by the new monoshock, now a Kayaba, with externally adjustable damping (high/low speed compression and rebound). The fork is also Kayaba (leg diameter 48 mm) and the preload has been changed to a firmer setting. The new 2012 version of the TC250 has also had an aesthetic makeover, the frame is now black, InMould graphics (integrated into the plastic and absolutely resistant to washing), and anodised silver rims.
Engine:new cylinder head
The Husqvarna 250 cc four-stroke engine is a very modern design, and remains the most compact and lightest in its category. But when you want to provide the best, you can never rest on your laurels. So our engineers radically redesigned the layout and changed numerous suppliers. The improved performance of the new TC250 engine is the fruit of these radical changes. First of all the twin cam valve train was completely redesigned! With a totally new design, four titanium valves and a different piston, the increase in power and torque is considerable: more horsepower reaches the wheels.
The injection has also been completely changed (now Keihin, with 46 mm throttle body), the electronic ignition is Kokusan, and the exhaust is new too. It comes fitted with ‘Power Bomb’ on the manifold and silencer from the specialists, Akrapovic.
Husqvarna CR65: A serious start to a racing career
With the introduction of the 2012 CR65 young champions can take to the track with the right bike and a brand they will learn to love – because in addition to its top-of-the-class performance, it has the same lines and layout as the TC449. A “great” bike for great riders, the new CR65 has 14/12″ wheels, 6 speed gearbox, and above all, suspension that is externally adjustable for rebound and compression damping. For Husqvarna the CR65 is not “like a motocross bike”, it is a motocross bike!
Another example? The aluminum rear sub-frame rail is easily removed for ease of maintenance and transport. The same care and thought went into the design and development of all details. For example the disc brakes and the hydraulic clutch.
The engine of the Husqvarna CR65 can threaten adversaries, but the power delivery is just right for those learning to handle a powerful bike and go on to become champions. The single cylinder is 65 cc, water cooled, with two radiators, because the CR65′s engine has all the horsepower to triumph and make its riders the champions of the future. Above all else, the engine is absolutely reliable. Air intake is by means of reed valve and a large Mikuni 24 mm carburettor. The 6 speed gearbox has a clutch with hydraulic command, for more sensitivity and less strain on the rider.
Light and compact
The steel frame is a tried and tested mix of round and oval tubing, the steering-head is inclined at an angle of 25.6°: the right compromise for stability and ease of handling, together with freedom of movement of the slim and streamlined bodywork. The suspension is professional standard. The front forks are 35mm upside down Marzocchi units, externally adjustable for rebound and compression damping. The rear end is suspended by a Sachs rear shock, fully adjustable for spring preload, compression and rebound damping, which controls an alloy swing arm.
The hydraulic disc brakes use a 4 piston callipers at the front, 2 piston callipers in the rear and the discs are outsized: 200 mm (front) and 165 mm (rear). The overall weight is just 55 kg [121 lb.] on the curb without fuel!
