The 2004 4-stroke Husqvarnas share the same body style of the TE
510 Centennial, the motorcycle created for celebrating the first 100 years of
Husqvarna motorcycle history. Fuel tank, seat, sidecovers, front number plate
and front fender have the same shape as the TEC 510, giving the 2005
motocross/enduro models a new look which is particularly streamlined. The
"centennial" connotation of 2004 models isn't just an aesthetic aspect, since
Husqvarna wanted to mark a clear step forward under the technical aspect
applying significant modifications aimed at improving the performance and
function of the TE 450.
Beginning with the engines, the top end is fitted with new valves, still made of
Titanium, now having stems of increased diameter for improved strength even in
the most severe riding conditions. The manufacturing technology of the valves
has been improved and the new supplier is one of the best in the field of racing
cars engines. The intake camshaft of TE 450 has been redesigned with new lift
profiles, optimized to increase the performance and the interaction between
valve and valve seat. The new cylinder head gasket , which is now made of multi
layer steel sheets (MLS), reduces head deformations and improves temperature
distribution of the power train.
Another significant change common to all 4-stroke models is the adoption of the
latest generation of Keihin FCR type carburetors with a 41mm bore for the 450.
The new carburetor setting, specifically developed for Husqvarna, improves the
throttle response at any riding conditions. Cold starts, as well as hot restart
are made easier due to the double choke system COLD/HOT including the classic
RED "electric start" button. All Husqvarna 4-stroke engines have electric
starters, a kick-starting kit is available as an option.
The 450's primary drive is now very similar to the 510's, with a high strength
aluminum (Ergal) clutch basket machined from the sound material with hard
anodine oxidation coating to improve clutch discs sliding and reduce wear on the
contact surface. Also improved for the 450 is the crankshaft, where con-rod pin
diameter increased from 30 to 34 mm, a new roller bearing with increased load
capacity and silver plated cage, a redesigned connecting rod and a different
balancing of the crank to reduce the vibrations.
Significant work was also done to the entire electrical system. The digital CPU
is programmable and recognizes both throttle position (TPS) and individual gears
(GPS). To make starting easier, ignition timing was modified and the new
generator has an improved battery re-charging circuit that delivers more
charging current starting from lower revs.
For the chassis, changes were made to improve the suspension and brake
components. This is why all models are fitted with new Sachs shock absorbers
equipped with a top-out spring, improving the suspension's function mainly
during rebound, and in particular during braking hard, reducing the "bouncing"
that is often noticed in deceleration. The shock absorber also has new sealing
rings and reservoir tank, which was re-designed to improve cooling. Also new is
the lower shock absorber pivot, that now features a roller bearing. All needle
bearings in the rear suspension link are now longer, to decrease friction and
improve durability. The suspension settings are completely re-worked following
the recommendations from Husqvarna Motocross and Enduro factory riders. The rear
brake disc has no holes and the front brake features a new master cylinder that
improves braking modulation.
All enduro models have a tub/tank for vapor recovery of coolant liquids, useful
mainly for mule track stretches for maintaining constant coolant capacity of the
radiators.
The electrical system is equipped with a device for preventing accidental
starting of the engine while in gear, with a switch positioned on the clutch
lever.
