Pre-mix. Reed valves. Expansion chambers. All three are terms new, or even relatively new motorcyclists won’t recognize, as the two-stroke engine gives way to the cleaner-burning, yet less efficient, four-stroke. Thankfully, the two-stoke is living on in the dirt world, and this captivating video by Adam Riemann entitled “The Power Of Sound” captures exactly what […]
2012 Husqvarna TC/CR Motocross Models Announced
Husqvarna announced its 2012 motocross lineup including the updated TC250 and TC449 four-stroke models and CR125 two-stroke.
Like the previously announced TE dual sports and TXC and WR off-road models, Husqvarna‘s 2012 motocross line receives new all-black chromoly frames with added structural reinforcement, and silver anodized Excel rims.
2012 Husqvarna TC250
The 2012 Husqvarna TC250 (pictured above) receives a new engine with a lighter piston and updated cylinder head, both borrowing from parent company BMW’s Formula 1 developments. Valve finger followers received a diamond-like carbon (DLC) coating Husqvarna claims make them longer lasting and smoother operating.
For 2012, the TC250′s battery-less fuel injection system switches to a Keihin ECU and throttle body from the 2011 model’s Mikuni components. Husqvarna added a CDI ignition system with a coil that uses less voltage than the previous unit, as well as a new airbox and Akrapovic exhaust system. Overall, Husqvarna claims the TC250 receives a substantial power increase from the 2011 model, particularly at higher revs.
The suspension has also been revised, with a new Kayaba 48mm closed-cartridge fork and link-mounted rear shock, both developed specifically for the U.S. market. Brakes remain the same as 2011 with Brembo hydraulics and rotors.
The 2012 Husqvarna TC250 will be available at a price of $6,999.
2012 Husqvarna TC449
The fuel-injected TC449 also receives some engine updates including new valve timing and DLC coating on the connecting rod. The ignition system uses a dual-map configuration, selected from a handlebar-mounted switch. Other engine updates include a larger airbox to improve mid-range power and a new WP radiator to improve cooling.
Like the TC250, the TC449 gets updated Kayaba suspension designed for the U.S. market.
Husqvarna has priced the 2012 TC449 at $7,999.
2012 Husqvarna CR125
As with its WR two-stroke line, Husqvarna’s smallest two-stroke motocrosser is returning to a 125cc displacement, but will come with a 144cc bore kit with cylinder and piston. The CR125′s engine is equipped with a Mikuni TMX38 carburetor with V-Force reed valves and a Ducati Energy digital igntiion.
Like the WR125, the CR125 is equipped with a 48mm Kayaba fork and Sachs monoshock and Brembo brakes.
The 2012 Husqvarna CR125 will be offered at $5,999.
