I am officially back in Flagstaff AZ and done with major bouncing around and traveling for a few months. Time to get caught up with Blogging and get a
DS Rally put together!
Dave Z. and I rode the second section of the course this past weekend. We only hit a few of the caches as the main objective was to evaluate that section of the course. The Cinder Pit pictured here is classic of northern AZ terrain. It rides like deep sand but thrashes tires like sharp rock!
We will ride the first section of the course this weekend. If Dave cannot ride on Saturday, I may be volunteering at the
AZ State Championship mountain bike race happening on Mt Elden, one of our local mountains, as a m
obile course marshal/
WFR since I
gotz the
moto.
Either way, I have some great riding ahead of me in the next few days.
And now a quick shot to the very recent past...
I
received the
Cogent Dynamics Moab shock and fully rebuilt front forks. Rick at
MotoCD.com was absolutely fantastic and a treat to deal with. The suspension is more than
noticeably different! I actually got to test it out on a long ride into the mountains of San
Jacinto in Southern California. The new suspension -along with the
knee braces I wore for the first time- saved me from what should have been a
low side on a
slow speed turn when my front tire flatted! More on that exciting story on a soon to come post...it deserves its own!
The craftsmanship is simply impeccable, it is very light weight in hand even without comparing it to stock, and is pretty
freakin' sexy (if you're a
bike-sexual).
Their prices are among the top best currently available.
I asked Rick at Cogent Dynamics to tune the suspension for hard
off road riding ranging from fast loose
fire-roads to slow technical rock gardens. Also ordered two coils. One is set for my 135lb body weight plus 35lbs of cargo gear and the second for riding with 200lbs of cargo gear -for upcoming
moto adventures of course.
When the units arrived via FedEx I inspected the boxes immediately. Much to my alarm I discovered the stock
presta valves of one of the fork legs had punched through what I presume to be the bottom end as it stacked in the truck. The valve was damaged and a fairly small amount of oil soak could be seen. It seemed to me the box containing my fork legs had been placed vertical, upside-down.
I called Rick and described the scenario. Ultimately we decided that the "damaged" fork leg may not have been compromised judging by the small amount of oil soak I described. The only way to know for certain if too much oil had leaked out was to literally open it up or by riding the bike and experiencing any negative
perceived performance. I opted for choice number two and did not notice anything obscene. Actually, I only noticed
impressive suspension oscillation
on road and off.
What a relief.
The damaged
presta valve is not a concern since they do not have an
imperative function anymore with the new internals (other than holding oil in).
The rebuild included progressively wound springs,
RaceTech cartridge
emulators, new seals, bushings and oil.
The cartridge emulators control the low and
high speed damping oscillation of the front
suspension. My only reference to any of this comes from my long time quest to use mountain bike suspension during my
pursuit of racing. Grant it, bicycle suspension internals are different from that of
motos, but they do get much of their technology from the motorcycle industry and suspension dynamics is still suspension dynamics no matter what machine it is used on.
Here is a great link describing the differences between emulators and other kinds of motorcycle front suspension :

The installation of the forks and fork brace as well as the Cogent Dynamic
Moab Shock was very simple on the
KLR and should be no problem for the home mechanic with the right tools in hand. Originally I had intended on doing an How-to installation post but realized it has already been done very well elsewhere and was way too straight forward anyway.
Take this link [Cogent Dynamics Moab Shock and Spring Review]to a very well done and thorough product and performance review of the Cogent Dynamics Moab Shock and fork springs, on KLRWorld.com . The author, Hondo, did the fork spring installation himself and without the RaceTech cartridge emulators, whereas my forks were sent to Cogent Dynamics for a full rebuild and upgrade.
Now back in Flagstaff, I am able to put them on a full test run to
develop an opinion on their intended performance prowess through a wide array of terrain. Today and the rest of the weekend I will do a full run of the
CGDSR course and will report back with my thoughts.
Cheers
