General Improvements to the whole 2003 KTM EXC range Fork - In 2003, all EXC models will be outfitted with White Power USD 48 mm
forks. In contrast to the 43 mm of 2002, the new fork has now three bushes per
fork tube, which ensures a better guidance of the inner tubes during compression
travel. Both wipe and radial shaft seal, as well as the bearings, were obtained
from new suppliers and, in combination with a new fork oil, ensure a markedly
improved response.
KTM also improved chromium quality of the fork coating to prevent excessive
“pumping up“ of the fork in use. The fork plates on the Enduro models were
adapted to the new fork diameter.
Shock Absorber - The WP PDS shock absorber was modified considerably. A bigger
compensating tank and a larger oil volume prevent premature fading. Changed flow
cross-sections for the oil stream and new tuning setups provide better
progression. This results in an improved response with a greater impact
resistance.
Axle/Hub - All EXC models come with a new front-wheel axle enlarged from 20 to
26 mm for greater directional stability, stiffness and a more accurate turn-in
ability. The front-wheel hub was also given a new design and its diameter
increased from 36 to 52 mm. The rear-wheel hub was also reinforced from 48 to 64
mm.
Handlebar/Footrest - All 2-stroke EXC models come with a high quality conified
Renthal handlebar, all 4-stroke EXC models with a 12mm higher Magura handlebar
of identical design. All 2003 EXC models will be fitted with the broader
footrests of the SX machines.
Clutch Hose - To prevent damage all models are fitted with flexible steel clutch
hoses.
Tank/Spoiler - All EXC models boast a new tank with the “SX“ look. Also the
shape of the tank shrouds is made uniform for both models. The advantage for the
Enduro models is a more ergonomic tank/seat contour and thus a better sitting
position. All tanks come in a basic orange, slightly transparent. The EXC tanks
are equipped with new fuel cocks.
Speedometer - The Enduro models come with a highly functional digital
speedometer with a control unit which, as an option, can be remote controlled at
the end of the handlebar (trip master).
Plastic Components - The new series look for 2003 is taken from KTM’s winning
2002 GP Team. All models come with a newly designed front wheel fender for
improved splash protection. A full-width radiator guard (on the 4-stroke racing
KTM’s) provides for optimum air guidance and efficient cooling. A new, seamless
seat cover creates an ideal surface.
Graphics Design/Colors - In 2003 the rear mudguard and the side paneling are
orange, the shrouds, lamp mask, and the front mudguard is also orange. The seat
is black. The KTM shroud logo was given a new design so as to cover the entire
shroud. The frame and the hubs are power-coated in a gold hue, matching the
color of the fork and the handlebar.
Improvements specific to the 200 EXC
Transmission - Considering the ever increasing engine performance of recent
models, the new 125/200 6-gear transmission now comes with a new, wider and thus
more load-resistant 2nd gear.
Gearshift Mechanism - A new aluminum gear selector drum having narrower shift
grooves permits an even smoother shifting operation, especially in extreme-load
situations (powershift). In addition, a new bearing roller of the gearshift fork
helps minimize wear.
Crank gear/Piston - The 200cc models are given a new crankshaft for improved
balancing and reduced inertia weight. The result is the reduction of vibrations
and weight as well as a quicker throttle response.
Cylinder - A new molded silicone ring supersedes the paper seal to provide ideal
sealing for the 200cc cylinder head. The combustion chamber in the cylinder head
was given a new shape and the transfer ducts were modified in a new casting mold
for optimum power yield.
