When it comes time
to personalize and fine-tune a new motorcycle, many things are often
overlooked. Most new-motorcycle owners are quick to run out and buy the
latest after-market exhaust, or the coolest new billet product
available. But the majority (not all) of those products won't help you
get around the course faster, or with less fatigue. This is where
personalized suspension tuning falls into the picture. The '02 Hondas
have good, high quality suspension right out of the crate, but it is
designed for what they consider the "average" rider to be,
which is typically around 170lbs., or even slightly less.

Problem vs. Dick's Racing Solution |

A
fully race-prepped machine ready to handle nearly anything... |
After talking with
Dick over the phone a few times, we discussed the problems that are
involved with the CRF's forks and shock. "The CRF's Showa forks and
shock are unbalanced. The forks are too stiff, and the shock is too
soft," stated Dick. I quickly agreed, as this was an obvious
problem. The forks didn't seem too bad, until I began to realize how
harsh the initial stroke of the forks was. When landing from a jump onto
flat ground, the forks sent a painful vibration through the bars. It
felt as though the forks did not move at all.
"What I
noticed about the shock, is that when I'm running in high gear across a
long set of whoops, the rear end wants to swap left to right a little,
" I commented. "That is because the shock spring is too soft,
and the rebound is too slow...the shock is packing and doesn't have
anywhere to go when it is forced through something like a set of whoops.
When I increase the rear spring rate, we'll increase the damping
too," answered Dick Wilk.

The
Dick's Racing suspension improves control in any environment. |
Ever since the CRF
came out in late 2001, Dick has been testing the Showa twin-chamber
forks and the Showa rear shock, in both off-road and MX applications.
After talking a few more times with Dick, he stated that he has a few
different programs targeted toward specific avenues of riding. He can
tune the suspension for 100% off-road, 100% motocross, or he explained
that he has found a great happy medium for the GP rider who likes to do
both, which fits me exactly. This is what Dick had in mind for my
suspension:
- Revalve the
forks
- Reduce the oil
level from 425cc to 350cc
- Change the
spring rate from .47 to .46
- Revalve the
shock
- Change spring
rate from 5.4 to 5.6
- Increase
rebound in shock

a line, any line. The improved feel of the forks made for easier
and more confident line choices through corners. |
At the last
minute, I finally worked out travel arrangements to get up to the
Washougal WORCS race. I conned the guys at RTT Motorsports into hauling
my bike up north, while RTT Motorsports co-head honcho Sonny Morgan and
I flew up to have a few days of fun in real dirt, and real riding
country. Just days before, I dropped my suspension off at the Dick's
Racing headquarters in Las Vegas, with a scheduled completion time just
before the departure date.
Everything came
together after a few stressful moments, and suddenly I was at the
beautiful Washougal motocross track getting ready for my first race with
the new suspension. The first aspect noticed, was the great feeling
coming through the forks....nothing! They were plush as could be, and
produced an obvious improvement over stock. The WORCS course started on
the MX track, looping us through the trees, a great rolling-hills grass
track, and more rutted, rough woods trails...a great course. The first
eye opener was discovered while dicing through the grass track. It had
of course rained throughout the day, creating extreme braking and
accelerating bumps in and out of every corner. The Dick's tuned CRF
never swapped for a second, as it allowed me to push harder into
corners, and pick phenomenal lines while exiting.

Dick
raised the spring rate of the rear spring, making for a more
balanced playing field between the forks and the shock. |
The shock just
followed up with the stellar performance of the Showa twin-chamber
forks. Finally, the bike was balanced front and rear, whereas before the
rear end of the bike always felt as though it was wallowing through the
bumps, not reacting as quickly as it should. The biggest eye opener came
on the first lap (which is when most eye openers happen). The course
dropped out of the woods and down toward the MX track. I didn't net the
greatest start, and was doing my part to make up time. This is when most
of us throw our brains out the window and put the controls on
"auto-moron". At the bottom of the hill lied a camouflage
bump....a BIG bump. It was the kind that made you pretty sure that it
was time to bail. But I was confident, and just hit it as prepared as I
could be. The result? Nothing, really....the bike just soaked it with
the rear wheel just barely coming off of the ground.
"Well, what
did you think of Dick's suspension?" asked KTM's Chuck Sun.
"Without any time to test, or even be remotely prepared....I
thought it worked great. The front end never swapped coming into those
huge braking bumps in the grass track, which was major. It was a great
feeling to be able to pass people because of the ability to keep it on
the gas longer into corners. It also seemed to allow the ability to pick
and choose any line I wanted...the front end just stuck. That CRF is
incredibly stable, " I answered, still covered in Washougal mud.

As stated earlier,
Dick offers different tuning programs to suit any rider's requirements.
Dick's forte is building suspension that handles anything an off-road
course can throw at you; whether that is a huge rock unseen until the
last minute, or an invisible 10 foot drop off. Dick's Racing has been
designing a special fork targeted for pure off-road use for months.
Before we decided what to do with my forks, Dick, Chuck Sun and I went
up to the brutal mountains of Northwest Las Vegas to test his new
creation on the ORC CRF.
Dick's Racing set
the forks up to where each adjuster had it's own duty:
• the lower right adjuster controls Rebound
• the upper right controls Mid Compression
• the upper left controls bottoming resistance
• and the lower left controls low speed compression
How did they work?
The forks felt strange at first, reason being is that they are
dramatically softer than the stock forks. But the more I rode, the more
I realized that "strange" turned into "excellent
control". Right out of the back of our trucks, the course we
decided to take was a whoop-littered speedfest. Thinking that I had
something to prove, I forgot about a relatively large drop-off that
comes up on a rider quite quickly. Problem? Other than my heart rate,
no. The forks soaked up everything that the drop-off had to offer, and
just kept on going. Dicks' creation allowed the forks to stay on the
ground more, and allowed for a better, but much different feel. After
covering a wide variety of terrain, we stopped to see how much travel I
was using. Amazingly enough, there was still a solid 4-5 inches yet to
be used! The forte of these forks is the ability to soak up nearly any
rock, whoop or any obstuction at high speeds, while still have great
resistance to bottoming, as we found out.
Its pretty easy to
say that the Dick's Racing suspension is nothing short of a huge
improvement over the stock suspenders. Dick Wilk is still doing all the
work himself, seeing to it that each and every fork, shock, motor and
carb it taken seriously and massaged with his multitude of experience.

- We
really had to stretch to think of negative aspects regarding
the Dick's Racing suspension. The only thing is that it may
be a little soft for MX, but that is more a matter of
"clicker" adjustments, and maybe oil levels, in
extreme cases.
