Husqvarna released information on its 2011 line of 250cc-based four-stroke TE, TCi and TXCi off-road bikes, and highlighting the list is the all-new TE310, derived from the 250cc X-Light engine.
Below is what Husqvarna says about its new small-bore off-road thumpers.
TCi250
The most important changes are to the engine, now fitted with a Mikuni batteryless electronic fuel injection system and 45mm-diameter throttle body. The major changes to the engine are to the cylinder head, with a new profile that has enabled an increase in power throughout the curve. The camshaft fuel intake line and exhaust are new, as well as the intake phasing.
The engine crank-case has been reinforced and now has steel sockets on chassis connections. The Akrapovic exhaust pipe has been specially designed by the manufacturer in Slovenia for Husqvarna and has a steel manifold, titanium silencer and steel heat protection.
Concerning the chassis parts, the frame area below the engine cradle and near the footrests has been completely redesigned, with side plates of forged steel to reduce lateral mass and increase resistance to strain. This effectively creates a single plate covering the footrest and brake pedal connections. The cradle surface has been streamlined so as to reduce to a minimum any possible impact with the ground or other obstacles. The steering stem area has also been improved and reinforced.
The engine guards are made of a new material, providing better protection against knocks.
The mirror-finish aluminum hubs are new, now with standard perforations.
The bodywork has new graphics on the tank area, with In Mould Plastic Decoration which is incorporated in the actual material, not applied afterwards.
TEi250
Antoine Meo has tested and ridden to victory the TEi250 in the first part of the World Enduro Championship. Now it is ready to meet the wider public in the showrooms and at enduro races throughout the world. The TEi250 is without doubt the best-performing and most-wanted 250cc four-stroke enduro of the moment.
For the enduro version, the most important changes concern chassis, as the 2010 version engine already had a Mikuni fuel-injection system.
The chassis has been redesigned and reinforced at the specific request of the official CH Racing team, with a streamlined area below the cradle preventing knocks from uneven surfaces. The area around the footrest connections and rear-brake master cylinder mounting location has been improved to reduce contact with the heel and to facilitate movement by the rider on the pedals. A single plate covers the footrest and rear brake pump/pedal connections.
The suspension has been optimized, with a dedicated setting for enduro racing, both for the Kayaba forks and the Sachs shock absorber.
Fuel-tank capacity has been increased to 2.2 gallons.
The tank has a new pump which enables 100% consumption of available fuel.
The airbox has been redesigned to hold the filter better and improve resistance to water.
The engine guards are made of a new stronger material, providing better protection against contact with stones and other obstacles.
The mirror-finish aluminum Grimeca hubs are new, now with standard perforations.
The bodywork has new graphics on the tank side panels, with In Mould Plastic Decoration which is incorporated in the actual material, not applied afterwards.
The design and look of hand guards included in the kit are also new.
The engine has been redesigned, improving power at low revs thanks to the ability to choose between two different CDI maps configuration by means of a handlebar switch - for hard or soft ground, depending on the style of riding and condition of the track.
The layout of radiator hoses is also new, as well as the position of the exhaust silencer now with new db killer and vastly improved heat protection in the silencer connection area.
TXCi250
The new TXCi250 receives all the improvements and refinements as the TEi250 but with some small differences to make this motorcycle ideally suited for U.S. hare scrambles, desert, GNCC and enduro competition. This is the first choice of factory rider Glenn Kearney who has successfully campaigned a TXC250 in the 2010 GNCC XC1 and National Enduro Series competition. Glenn has consistently finished in the top five of both series riding the "little" 250 against Open-class machines without a single technical issue along the way. The TXCi250 is without doubt one of the best performing quarter-litre off-road motorcycles in the world today combining great power and an amazingly light feel. It receives the same technical improvements as the TEi250 with the exception of slightly more aggressive suspension settings for off road competition use. It receives all the same chassis and engine improvements along with the optional mapping ability for hard or soft terrain.
TE310
The all new TE310 boasts the lightest engine in the 250cc four-stroke category (48.5 lbs.), boosted to 302.44cc, thanks to an increase in bore and stroke, now 82 X 57.3 mm. The power output is simply amazing with a considerably higher torque curve than the 250 version.
The throttle body is the same as that on the TCi250 - a Mikuni 45 mm diameter. The exhaust system is specially designed for the 310 model and as in the other models has a new heat protection on the silencer.
The bike is much lighter than the previous version (by 13.2 lbs.) and comes with significantly higher torque and power.
Otherwise the bike has the same features as the TEi250, with the new reinforced chassis, new Grimeca hubs, Kayaba 48mm front forks and Sachs shock absorber with new settings, 2.2 gallon fuel tank, new hand guards and new bodywork graphics.
