WHAT IS IT? The Boyesen FlexGrip allows a small
amount of flex in the clutch-side grip to lessen the force
of impacts (just like the throttle side). It is like having a
throttle on both sides.
WHAT’S IT COST? $39.95.

WHAT STANDS OUT? Here’s a list of things that stand
out with Boyesen’s FlexGrip system.
(1) Two designs. In 1995 Boyesen Engineering
introduced the Shokout grip. It looked exactly like a
throttle for the clutch side of the bike. It was very
creative and used elastomer bumpers to fine-tune the
amount of flex that the clutch grip offered. It is still
offered by Boyesen, but 16 years after the introduction
of the Shokout grip, Boyesen was inspired to make a
simpler and less expensive version of the idea—the
FlexGrip. The FlexGrip still offers shock-absorbing give in
jumps and whoops, but it does so with a lot fewer parts
than the Shokout grip. The FlexGrip is smaller, lighter
and almost unnoticeable.
( 2) Competition. It’s strange that Boyesen is
competing with itself in the grip shock-absorption
business. Although there are gel grips, flex bars and air
triple clamps, only Boyesen has ever tried to tackle the
problem with a rotating clutch-side grip, and they have
had the market to themselves for 19 years.
( 3) FlexGrip system. What makes the FlexGrip so
innovative is that compared to the Shokout grip, it has
almost no moving parts. Say what? How can a part that
rotates when it hits bumps have no moving parts? Okay,
we lied. It does have one moving part, but it moves
without gears, cams, bearings or housings. How does
it do it? The FlexGrip looks like a clamp-on-style grip,
but the hidden white nylon tube has longitudinal slots
cut into it that allow it to flex or, more accurately, twist
when placed under a load. As you hit bumps, the left
grip absorbs the blow by rotating slightly, either forward
or backward, to take the load off your hand, wrist and
( 4) Grip choice. The FlexGrip comes with a set of
Scott grips (already mounted on the clutch side), but
since the complete system mimics a clamp-on grip
system, you can run any grip you want.
( 5) Psychology. Every MXA test rider felt that the
FlexGrip had some benefits. Some were distracted by the
grip’s movement, but for a rider with any type of wrist
or arm injury, the grip was a hit. There is no doubt
that the Boyesen FlexGrip grip can lessen arm pump,
decrease handlebar vibration and reduce micro-trauma
in the whoops.
WHAT’S THE SQUAWK? The feeling of the left grip
moving seems alien to motocross racers, even though
the throttle-side grip moves like a pinwheel.
If you suffer from terminal arm pump, have a
wrist injury or are looking to lessen your death
grip on the bars, the Boyesen FlexGrip is a
five-star product. But, for a rider who can’t
separate his right hand from his left, it is a
