2009 Husqvarna TXC 450, Marzocchi shiver USD forks, Excel rims. Ready for a day in the dirt. - TXC450 - HUSQVARNA The new TXC 450 is an exact replica of the machine raced by Glen Kearney and Gordon Crockard in the American GNCC championship. Fitted with a lighter more manageable frame, the 450 has the same technical modifications as all the 2009 TXC models: Wave type brake discs, new swing arm calibration, new Sachs shock absorber and a new look with color coded graphics. The engine has a new oil circuit pressure relief valve, a new lubrication system for the con rod bearings and a new filter to prolong bearing life. The gearbox has been updated to offer improved gear change speed and accuracy. Gearbox design has seen changes in terms of gear change linkage, lever and selector mechanisms. The 450 engine has also benefited from a new timing gear chain tensioner that was introduced to improve chain tension and reduce contact pressure. Thanks to this new design, component durability has been extended.
