Front Fork Operation
The front suspension on the CX50SR works under the principals of hydraulic damping,
and it features full adjustability to help tune the fork to meet each rider’s needs. The
CARD fork contains MXT ‘Smart Leg’ technology that provides very progressive
operation; allowing a small bike to perform well on track surfaces ripped up by larger
machines.
The key to Smart Leg technology is to understand that each leg has a different
role. The brake side leg features a conventional open cartridge. This cartridge
handles both standard compression and rebound damping duties. Rebound
damping is adjustable on the fork cap, and compression damping is adjusted at
the bottom of the fork. The other leg (the Smart Leg) has no rebound damping,
and it contains both a speed sensitive compression damping mechanism as well
as a position sensitive one. This design allows for a firm low speed response,
controlling rapid chassis pitch, which promotes stability and control. The fork
produces significantly less mid and high-speed compression until it travels into
the progressive / speed sensitive portion of the smart leg. The speed sensitive
compression component is adjustable at the top of the fork.
The combination of the Smart Leg and the conventional leg allows the fork to be
very supple throughout all low amplitude operation and yet take punishing hits;
producing a progressively increasing damping rate that slows the forks
movement as it approaches full bottom. Therefore, the Smart Leg also acts as a
hydraulic bottoming control device. Finally, the large degree of adjustability in
both legs allows the fork to be tuned to meet each rider’s size, ability, and type of
riding they do (motocross, off-road, flat track, etc).
Fork Damping Adjustments
Tools required

Small flat blade screwdriver
The speed at which the fork rebounds can be adjusted
at the top of the conventional leg.
Turning the adjustment screw
clockwise slows the rate at which
the fork extends after being
compressed, and likewise, turning
the screw counter-clockwise
returns the leg to its extended
position faster. As shown in the
figure, ‘S’ (slower) and ‘F’ (faster)
are etched into the cap as an adjustment guide.
