Husqvarna TXC250, 2011
TXC250 - HUSQVARNA The TXC 250 is a completely new, revolutionary machine. The biggest innovation is the new 250 cc engine that, at only 22 Kg., is without any shadow of doubt the point of reference for this category.
Compared with the TXC 08 engine, on the new 250 Husqvarna, the distance between the primary transmission and the centre is decreased by about 16% and the distance between the gearbox and the centre is reduced by about 7%. Length, width and height have been decreased by 13%.
The single cylinder water-cooled four-stroke engine features 4 radial valves while bore and stroke are 79 and 50.9 mm respectively to give a capacity of 249.5 cc.
The engine breathes through 4 titanium radial valves driven by twin overhead combined chain/gear drive cams.
Wet multi-plate clutch, 7 driving plates - 6 driven.
Five-speed constant mesh gearbox. Lubrication is taken care of by a dry sump system with rotor pump. The engine and gearbox combined hold about 900 grams of oil. The TXC has both electric and kick start systems.
The frame is completely new, lighter and has a redesigned geometry. All the body panels have been redesigned so as to make the bike especially compact, slim and manageable. The dry weight of the new Husqvarna is the minimum allowable in its category thus adding to its appeal and performance.
The rear suspension has a new Soft Damp system with a new leverage ratio, new progression curve and decreased frame load. The chain tension effect has been optimised as has the traction. The new aluminium swing arm features an asymmetric geometry extruded box aluminium centre housing the off-set shock absorber.
The suspension features new sealed cartridge Kayaba 48 mm forks and a new Sachs shock absorber. The brakes discs are of daisy (wave) design.
