2012 Husqvarna TE511
A NEW BREED
Husqvarna has always strived to innovate
and bring new ideas to the world of off road motorcycles.
Now, as always, the motorcycle brand with the longest
tradition in the world in the Off Road sector is fully
committed to the ongoing research and development
of the perfect off road bike: easy to use, ready to
race and easy to maintain.
The design of the new 449/511 range
outstrips that of other off road models and stands
out immediately for its looks, exclusive layout and
DESIGN AND LAYOUT
The line 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 jeans on the edges of the panels
with this design.
Besides the aesthetic and ergonomic
aspects, the new design also makes maintenance easier
as the air filter, rear shock and throttle body can
all be accessed with ease. The long seat, which runs
from the rear mudguard to the steering head, offers
completely free longitudinal movement.
Aesthetics, technology and serviceability
too: the graphics on the side panels are applied using
the ‘In Mould Design’ technology for increased
resistance to wear and the 2 litre fuel pump housing
is transparent so that the remaining fuel level can
be easily monitored.
MASSES AND CENTER OF GRAVITY
The idea behind the TE 449/511 range
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 competitive Enduro
racing. 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.
This solution allows a longer swing
arm whilst still retaining a wheelbase similar to
our competitors, ensuing greater traction, which for
Enduro means tangible advantages.
The chassis layout allows the modern
DOHC engine to be mounted closer to the centre of
the bike, whilst tilting the cylinder further forward
allows a long and straight air intake path at the
same time as keeping the centre of gravity as low
as possible. This has also meant that the throttle
body and fuel injector nozzle can be mounted in the
Again, continuing the theme of mass
centralisation, the two part fuel tank design provides
a total of 8.5 litres capacity in a low mounted 2
litre pump housing and a 6,5 litre under seat main
tank. The under seat fuel tank layout permits the
airbox to be located in a protected and fluidodynamically
favourable position above the engine with the actual
air intake being at the height of the steering column,
in a raised and sheltered position to minimise the
intake of dust or water.
The air filter box has an elongated
intake manifold and a newly designed air intake to
provide greater breathability for the sponge filter,
which is easily removed thanks to a hinge system in
The battery is located adjacent to
the under seat main fuel tank to again centralise
The TE 449/511 bikes are 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 offroad 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. All components are
top of the range - the bike even comes with two exhaust
silencers: the Euro 3 compliant silencer fitted as
standard and a steel Akrapovic Racing exhaust, developed
in collaboration with the Slovenian company to maximise
the potential of the engine, whilst minimising the
The gear ratios for both the Enduro
and MX versions have been completely changed: the
Enduro now uses a 6 speed transmission and the ratios
have been modified on the basis of the experience
gained during Salminen and Tarkkala's races. The ignition
timing has been optimised with maps specific to the
two different capacities and exhaust systems.
The TE 511 version has been achieved
by increasing the cylinder bore from 98 mm to 101
mm, with the stroke remaining at 59.6 mm. The effective
displacement has therefore been increased to 478cc.
The clutch is controlled hydraulically,
offering a smoother and more progressive action with
greater consistency also under stress.
The motorcycle has a high energy electronic
ignition and, thanks to the powerful battery and fuel
injection system, a supplementary kick start is not
HANDLING AND PERFORMANCE
Naturally, Husqvarna's long experience
in Enduro racing has played an important part in the
development of these new motorcycles. The challenges
posed by the conception of geometry and by the general
concept of the motorcycle itself were linked to the
tough demands of riding in the most severe and extreme
conditions. The result is a surprisingly effortless
and smooth ride along with agility and outstanding
The perimeter design chassis is made
of high strength steel tubing. The geometry of the
rear suspension is revolutionary, with a new linkage
mounted on top of the alloy swing arm.
This solution offers many advantages:
it increases the ground clearance, improves general
reliability thanks to the reduced exposure of the
components and makes maintenance easier.
But there's more: dynamically, by exploiting
the advantages of the double cradle frame made in
high strength steel tubing, the roughness of the ground
is absorbed more gradually, attenuating the stresses
on the rider.
The advantages when jumping are also
remarkable with the recoil effect of the rear wheel
being significantly reduced and the smoothness of
the suspension is particularly perceivable on rougher
and more difficult ground.
COAXIAL TRACTION SYSTEM
A real refinement in the field of chassis
design and exclusive to the TE/TC 449/511 range is
the CTS, the Coaxial Traction System. This system
represents an evolution compared to the one adopted
on the BMW G 450X. The solution, which originally
used a single swing arm pivot spindle, now has two
independent semi spindles which reduce the stress
on the swing arm and facilitate the replacement of
the gearbox sprocket.
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.
This aspect has been studied by a spin-off
company of the University of Padova called Dynamotion
which has proved that the CTS improves traction in
the various stages of acceleration and consequently
during also the vertical movements of the suspension
on rough terrain.
The result is better traction during
acceleration and surer, more confident gear changes.
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
TOP OF THE RANGE COMPONENTS
The new TEs are equipped with the most
advanced components in the Off Road sector.
For the front brake, there is a Brembo
system with floating caliper and 260 mm wave rotor,
while the rear brake consists of a floating calliper
operating on a 240 mm rotor.
The suspension is entrusted in full
to the specialists of Kayaba, with 48 mm forks, adjustable
for compression and rebound damping and a Kayaba rear
shock absorber designed specifically for Enduro use
with settings optimised in collaboration with the

TE449/511 are also the sole standard
enduro bike on the market equipped with full Akrapovic
A range of Husqvarna Special Parts
will be available, developed by Husqvarna to provide
the best combination of lightness, durability and
performance to allow Husqvarna fans to personalise
their bikes and offer them the ingredients for racing
The motorcross version stands out not
only for the normal MX chassis changes (no lights,
19" rear wheel etc) but above all for the engine
which has been specifically tuned for MX use, delivering
significantly more power than the Enduro version.
The timing and camshaft profiles are
completely different as is the compression ratio which
has increased to 13:1 instead of 12:1 in the Enduro
version. The electronic injection system still uses
a 46mm Keihin throttle body but is fitted with a single
flap instead of the Enduro twin flap version to provide
a sharper, more aggressive throttle response. Additionally,
the TC449 is fitted with a dual mode switch on the
handlebars, which allows access to two different fuel
injection / ignition timing maps to provide a softer
power delivery for low traction conditions.
The titanium exhaust system with carbon
fibre tipped silencer has been developed specifically
by Akrapovic and the five speed transmission has specific
ratios for use in MX. The suspension is provided by
Kayaba with multi adjustable sealed cartridge front
forks matched to a Kayaba fully adjustable rear shock.
