Adjustments For Competition - Honda CRF450R 2009 Owner's Manual & Competition Handbook

This section tells you how to fine tune your CRF
for maximum competition performance.
Initial suspension adjustments should be
performed after a minimum of 2 hours of easy
break-in time.
Optional front and rear suspension springs are
available in both stiffer and softer than standard
rates, in order to tailor your CRF specifically for
your weight, riding style and course conditions.
Follow the instructions given in the rear
suspension sag setting section of Rear
Suspension Adjustments to determine if your
combined rider and sprung machine weight (rider
fully dressed for competition and machine
coolant, oil and fuel levels ready for competition)
requires an optional stiffer or softer rear spring.
The need for either optional rear spring may need
to be balanced by installing the optional fork
springs of a similar rate.
