2012 Husqvarna SMR630

2012 Husqvarna SMR630


The SMR 630 was inspired by the design of the 610, but completely renewed in terms of handling and performance.

The bodywork is all new, giving the bike a more streamlined and aggressive look. The seat, fuel tank, side panels, air ducts and mudguards at the front and rear all have a new design. The seat has new dual density padding to ensure greater comfort for rider and passenger even on longer routes. The passenger also has two convenient grab handles anchored to the rear sub-frame for a safer, more comfortable ride.

The new headlamp design offers greater lighting performance and is integrated into the headlight shield which in turn integrates with the “racing” front mudguard. The frame and swing arm have new black paint that compliments with either of the two new colour schemes: white and aluminium or white and black.

The bodywork on the elegant white and aluminium version benefits from the ‘in mould design’ process meaning all logos are moulded into the plastic during production for greater durability. On the more aggressive, sporty black and white version, the entire body is painted.

The design of the rear mudguard is also new, with a LED taillight and a new licence plate holder incorporated in the mudguard.

But the most innovative feature of the new SMR 630 is its 600 cc engine with bore increased from 98 mm to 100 mm. The DOHC head with a red painted cover is inherited from the Husqvarna 450/510 competition bikes and this permits a 20% increase in power over the earlier 576 cc version.

The SMR 630 has an electronic fuel injection system developed in collaboration with Mikuni. The engine features a 45 mm throttle body with the fast idle control on the handlebars and there is a 300 Kpa Mitsubishi "twin jet" fuel injector fitted to the throttle body. The pressure regulator (3 Bar) regulates any return of excess fuel to the tank and the MAQS (Modularised Air Quantity Sensor) consists of air temperature, air pressure and TPS (Throttle Position) sensors. The Kokusan 360W three-phase ignition flywheel is also new.

The water temperature sensor is on the cylinder head: the injection system control unit processes the signal from the sensor and operates the cooling fan on the right water radiator accordingly.

The bike has a completely new cooling system with a new impeller, pump body and thermostat.

The clutch now has hydraulic control and the left engine casing has been redesigned.

New components include a petrol tank with a 40l/h pump and a capacity of 12 l; the non-return fuel circuit has quick-fit connections for ease of removal.

The exhaust system on the four-stroke single cylinder engine has a "closed loop" lambda probe and twin aluminium exhaust silencers. The catalyser has been redesigned and optimised to meet Euro 3 requirements. The silencers are covered with stainless steel guards in the catalyser and passenger foot peg areas.

The front brake is a new Brembo radial calliper with racing origins, operating on a 320 mm floating disc, while the rear brakes have a 220 mm disc with a Brembo single piston calliper.

The suspension system consists of 45mm Marzocchi adjustable forks mated with a Sachs rear shock absorber. The Marzocchi forks are anodised black to match the Husqvarna competition range.

The 2011 version of the SMR 630 will have Magura tapered handlebars with new steering head clamps and no cross bar.
