2012 Husqvarna SMR630
THE NEW HUSQVARNA SMR 630
The SMR 630 was inspired by the design
of the 610, but completely renewed in terms of handling
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
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
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.
