Yamaha KODIAK ULTRAMATIC YFM400FA Owner's Manual page 234

Whenever possible, ride your ATV straight
downhill. Avoid sharp angles which could al-
low the ATV to tip or roll over. Carefully choose
your path and ride no faster than you will be
able to react to obstacles which may appear.
WARNING
Always follow proper procedures for going
down hills as described in this Owner's Manu-
al.
Note: a special technique is required when
braking as you go down a hill.
Always check the terrain carefully before
you start down any hill.
Shift your weight backward.
Never go down a hill at high speed.
Avoid going down a hill at an angle that
would cause the vehicle to lean sharply to
one side. Go straight down the hill where
possible.
