Maintenance; Service Intervals - Manitou DORADO Owner's Manual

IRT (Infinite Rate Tune)
Dorado Pro forks are equipped with the IRT air spring system. The IRT is located
on the bottom of the spring side (left) leg. Infinite Rate Tune (IRT) allows for
advanced spring tuning by independently modifying air pressures in the beginning
and end stroke. IRT technology created a secondary air spring that effects on
the middle to end strong of the fork. This allows the main air spring to be set
to lower pressures for improved small bump sensitivity while maintaining mid
stroke support and moderate to aggressive end strong ramp up. For initial
setup information see the Dorado Pro setup guide. For more advanced tuning
information see the IRT advanced tuning guide.
Dorado Expert forks are equipped with Incremental Volume Adjust (IVA). The
IVA is located on the bottom of the spring side (left) leg. IVA is a self-contained
air volume adjustment system that allows the user to customize ramp up for
specific conditions. The self contained spacers can be moved on either side of the
air piston to change the positive air volume. For initial setup information see the
Dorado Expert setup guide. For more advanced tuning information see the IVA
advanced tuning guide.
The Dorado Comp uses a coil spring system with external preload located on the
bottom of the spring side (left) leg. See the Dorado Comp setup guide for spring
rate information and initial setup. Consult the service guide for changing spring
for the rider weight.

DORADO OWNER'S MANUAL

maintenance

Your fork requires periodic maintenance, cleaning, and inspection. Torque values
of bolts and fasteners must be checked periodically, more often if riding in
extreme conditions. To maintain top performance, it is recommended that the
fork be periodically disassembled, cleaned, dried and re-lubricated. Visit www.
