sharp bumps and increases bottoming resistance.
Kreft’s Rev2 mid-valve piston uses a twin-port design
for a larger compression port area that mates to a more
natural shim-bending motion. A Teflon-coated steel piston
band minimizes friction.
The 4CS bottoming control system delivers a hydraulic
cushion in the last 60mm of travel. With a newfound bottoming resistance, this system also allows for lower fork
oil levels and more compliant compression damping for
The 4CS damper has large, fixed bleed holes in the
fork cartridge. Kreft believes that the design provides little
damping control for low-speed action and forces WP to
compensate to keep the fork up. This makes it harsh.
Kreft’s goal is to control the oil flow at low speeds, creating a hydraulic cushion to support the fork in motion. Kreft
uses special inserts that seal off the factory bleed orifices
(both the upper and lower parts of the cartridge) to allow
the compression adjuster to do its job.
WHAT ABOUT THE SHOCK?
The Kreft folks like the WP shock design but put effort
into creative valving techniques. The big complaint is that
it’s a full rodeo in acceleration chop. Kreft valved in an
S-shaped damping curve that slightly reduces damping
force at the wheel velocities we see in braking and acceleration bumps. They also feel the shock struggles to find
traction in dry and chewed-up conditions. Kreft valves in
a setting that is faster overall, with the emphasis on freer
movement in the top 25 percent of the stroke.
THE TRACK TEST
Let’s cut to the chase: we enjoyed a huge improvement
up front! In comparison to the stock system, the Kreft
unit is smoother, plusher, more controlled and far better
at taking big hits. We tested it on three tracks on multiple off-road days and found that the system is definitely
moto-based, which is what we asked for, but has enough
versatility in the valving to let us enjoy our desert off-road
loop. It is not soft and mushy; it stays up in the stroke and
doesn’t wallow, yet the transition from low-speed track litter to big giant wallops is greeted with a smile rather than
a grimace. In off-road our terrain is super tight and cobby,
and here the fork still felt moto-oriented. Relaxing the
compression (now on the bottom!) by two clicks ( 17 is the
stock setting; we went out to 19) helped, but it still likes
speed and big bumps rather than rocks.
Out back the shock made better traction and was defi-
