You end up in a
heat based on
HEAT AM I
by how the
riders to the heat races and semis in
Supercross. Do they go by points?
Over the years, the AMA has
changed how they assign riders to
the heats and semis several times.
Currently, they use timed qualifying.
The rider with the fastest time gets
first gate pick in the second heat.
The second fastest time gets first
gate pick in the first heat. The third
fastest rider gets second pick in
the second heat, and they alternate
back and forth until the gate is full.
Before they had timed qualifying,
they used points to determine heat
race selection. Additionally, the two
semi-finals are made up of half
the riders from heat one and half
the riders from heat two mixed
together—that way the riders in the
semis don’t face the exact same
riders that they raced against in
their heat race (although they do
face half of the same riders). ❏

2010 YZ450F: Some mods will and
some mods won’t.
UPDATING A SUCCESSFUL
On my 2010 YZ450F, I added a
Steahly 9-ounce flywheel weight
and a longer Pro Circuit link. Both
of these mods worked well on
my 2010. Now I’m getting a 2014.
Will the mods from my 2010
transfer over to the 2014?
You can take the Pro Circuit
link off your 2010 YZ450F and put
it on the 2014 model; however,
your 2010 flywheel weight will
not fit on the 2014 YZ450F. You
will have to order the newest
version for $120 from
