Husqvarna SMR511

The design of the new SMR511 outstrips that of other supermoto models and stands out immediately for its looks, exclusive layout and cutting-edge technology.

The design is completely new: slim, svelte and refined. The single piece side panel runs from where traditionally the fuel tank would be, all the way back to the rear mudguard, allowing the rider free and unhindered movement. There is no chance of snagging boots or pants on the edges of the panels with this design. The long seat, which runs from the rear mudguard to the steering head, offers completely free longitudinal movement and has been modified compared to the Enduro version to improve rider comfort on longer journeys.

The idea behind the SMR511 is ‘mass centralisation’ – to keep the weight of the bike concentrated as close as possible to the centre of gravity and to design a chassis which adapts perfectly to the demands of use on the road and in the racing environment. This solution, which Husqvarna calls CTS (Coaxial Traction System), eliminates the variation in the length of the chain during rear suspension movement, minimising the effect of the final drive on the bikes handling. The crux of this concept is the union of the rear wheel swing arm pivot point and the gearbox output shaft sprocket. This solution, which Husqvarna calls CTS (Coaxial Traction System), eliminates the variation in the length of the chain during rear suspension movement, minimising the effect of the final drive on the bikes handling.

The SMR511 is equipped with a cutting-edge 4 valve dual camshaft engine which has been significantly improved thanks to the experience gained by Husqvarna in its many years of supermoto racing. Fuel delivery is managed by an electronic injection system with a Keihin 46 mm diameter, double flap throttle body which provides progressive and predictable throttle response. The secondary gearing has been tailored to suit the intended on road application of the bike and the fuel/ignition mapping has been optimised for performance and controllability in both capacity versions.

The SMR511 version has been achieved thanks to the increased cylinder bore of 101mmcompared to the 98mm of the 449. The stroke remains the same on both models at 59.6mm,giving the 511 an effective displacement of 480cc.

The clutch is controlled hydraulically, offering smoother and more gradual release with greater control also under stress. The motorcycle has a high energy electronic ignition and, thanks to the powerful battery and fuel injector system, a supplementary kick start is not necessary.

CTS - Coaxial Traction System

A real refinement in the field of chassis design and exclusive to the SMR 449/511 range is the CTS, the Coaxial Traction System. The advantages of the CTS system compared to the traditional systems are huge. During the suspension movement along the whole stroke, the chain is not subject to any change in length. The tension of the chain remains constant regardless of the swing arm position, while the chain and sprockets benefit from reduced wear. An important positive effect on the riding characteristics is the marked reduction of the impact of alternating the load on the transmission. More in general, the values obtained by adopting the CTS have a much more uniform trend in all conditions, leading to improved ridability and stability of the motorcycle.
