Fine Tuning the Power Delivery
The single-cylinder, titanium four-valve, DOHC motor is a recent design, one which needed few modifications - just some minor changes to fine-tune the power curve. To draw optimum performance from the TE449, designers focused on the mapping of the Keihin fuel injection. Cooling efficiency is improved with new WP radiators, which also help power flow freer. The TE511 certainly has no shortage of power. In fact, the biggest challenge is keeping all of its ponies in check. This is why engineers, riders and testers at Husqvarna have focused mainly on ease of handling with the TE511 motorcycle, and painstakingly developed a new Keihin ignition mapping specifically designed to deliver power from its 477.5cc DOHC four-stroke motor in a more linear, progressive fashion. Stopping capabilities are entrusted to Brembo and premium wave rotors are supplied by Braking. Cooling circuit efficiency on both models is further improved with a new WP radiator. The six-speed gearbox remains operated by a progressive Brembo hydraulic clutch, which affords a positive feel with a light touch. Starting is effortless with pushbutton command, and eliminating the kick-starter remains to be a good decision, given the reliable ignition and high-power battery of the TE449 and 511.
