Power up: The Engine Mode Select button allows for easy
mapping changes, thanks to three preprogrammed settings.
perfect entry-level powerband.
That is where the compliments end. Faster riders had
a tendency to over-ride the engine to the point where
they couldn’t recover from mistakes. Top-end power is
flat, while over-rev is minimal. Maximizing the CRF250
powerband requires an understanding that the engine
cannot sustain a heavy load. The best approach is to
keep the power in the midrange and shift before peak.
Otherwise, you’ll be going nowhere fast.
Q: HOW DOES THE 2015 HONDA CRF250
A: There are times, such as on tight tracks with
good traction, when the CRF250 shines. When the
conditions are right, the CRF250 can hit tight lines
easily; however, high-speed corners can be troublesome.
It’s a give-and-take situation at every turn. At times, the
front end has a mind of its own, wandering, drifting or
shaking like a dog in a rainstorm. That’s why it’s
imperative to achieve chassis balance.
Q: WHAT WOULD WE DO TO IMPROVE THE
2015 HONDA CRF250?
A: Find satisfaction by making these key changes:
(1) Steering stem. We go in on the HPSD steering
damper clicker, but don’t be afraid to crank down on
the steering stem nut also. Tighten it until excess slop is
gone when applying light pressure to the bars.
( 2) Mapping. We suggest trying the three maps in a
variety of conditions. Our favorite is the aggressive
setting (map three).
( 3) Exhaust. Dropkick the dual exhaust for an

SHOWA SFF TAC FORK SETTINGS
Gone are the 2014’s conventional Showa
cartridge forks; in their place are all-new Showa
SFF TAC air forks. There are three air chambers,
but only the inner and balance chamber are
adjustable on the CRF250. Note that there is a
valve opening to access the outer chamber, but it
has been blocked off. Expect aftermarket
companies to develop and sell a screw-in
Schrader valve that allows air pressure changes
in the outer chamber.
What’s the benefit of adjusting the outer chamber? We’ve learned that the outer chamber can
be used for bottoming control. Not having this
w for heavier or faster riders; however, it’s possible to achieve harmony with the SFF TAC fork.
Follow these steps for CRF250 suspension bliss.
(1) Set the correct air pressure for your weight
and riding style in the inner chamber. The inner
chamber should be adjusted in small increments,
while the balance chamber can be adjusted in
even smaller increments. We added more
pressure to the inner and balance chamber.
( 2) Get the chassis balanced. The CRF250 has a
stinkbug stance, with most of the weight directed
toward the front end. It’s best to alleviate weight
on the forks by adding air to the inner chamber,
lowering sag and adjusting fork height.
( 3) Remember to use the compression and
rebound fork adjusters. Don’t get caught up in
finding the perfect air pressure without also
trying different clicker settings.
For hardcore racing, these are MXA’s recommended 2015 Honda CRF250 fork settings (when
changed, stock settings are in parentheses):
Inner chamber: 180 psi (174 psi)
Balance chamber: 170 psi ( 163 psi)
Oil quantity: 357cc
Compression: 9 clicks out ( 5 clicks out)
Rebound: 10 clicks out ( 12 clicks out)
HPSD: 7 clicks out ( 9 clicks out)
Fork-leg height: Flush with top clamp
Notes: The chambers are interrelated.
SHOWA PRO-LINK SHOCK SETTINGS
Here is what the MXA wrecking crew ran in
its 2015 CRF250 (when changed, stock settings
are in parentheses):
Spring rate: 5. 3 kg/mm
Race sag: 104mm
Hi-compression: 3-1/4 turns out ( 3 turns out)
Lo-compression: 5 clicks out ( 10 clicks out)
Rebound: 6 clicks out ( 8 clicks out)
Notes: The shock is very sensitive to high-speed compression. Heavier riders should go in
1/4 turn on the high-speed compression and set
the sag at 100mm.
