KLR-650 Chain Master (Patent Pending) Upper Chain Run Control Device
*Engineered using a stock KLR-650 with properly adjusted chain.*

You know we are big fans of the KLR-650 and we think it's one of the two finest
big-bore multisurface motorcycles on the market. For some reason though, the folks at
Kawasaki have produced a motorcycle for off-road use with minimal lower, and
absolutely NO upper, chain run control. Look at any other off-road bike, like the
DR-650, and you'll find some sort of chain control, most commonly rollers. Elden
noticed this problem more than ten years ago and installed his own chain roller. The
only problem with Elden's method was that it required some nifty handiwork to drill
precisely through the sub-frame to provide a location for installation. Fast forward to
2006, and we asked Old Top Gun to take another look to find an easier solution. What
you see here is the culmination of a lot of research, a lot of time with a KLR-650 up on
the lift, some fine work by the good folks at MacDonald Products in San Diego, and
another tangible example of Elden's innovative problem solving ability.

This is our first
"neccessory" for the KLR-650. A great term coined by Elden, it
describes those items that may be aftermarket upgrades, but are vital to the long-term
health of your ride. In our minds, there are four neccessories for the KLR-650:
upgraded balancer lever & tensioner spring
with an inspection port ; a properly sized
and heavier straight-wound rear spring; a MacDonald Products upgraded shift lever;
and now the Chain Master. All of these products shareone thing in common - Elden
conceived or collaborated on every one - and the spring, shift lever, and Chain Master
can be found at
MMP.
Why do you need a Chain Master?

There are three main reasons that any
KLR-650 rider needs a Chain Master:

  • Protect airbox vent
  • Reduce chain slack at full rear
    suspension compression
  • Allows better engagement of the
    counter-sprocket by the chain
    during rear suspension compression

On the KLR-650, the airbox vent tube lies
directly above the chain and bears the
brunt of this omission.  In the picture to
the upper right, the airbox vent-tube cover
has been torn by the chain. This damage
obviously defeats the purpose of the vent
cover by c
reating a larger opening for dirt
and dust to enter the airbox.

Over time, the damage is more dramatic,
as evidenced by the picture to the right.
Here, the cover for the vent tube has
been completely torn away, and the
abrasion damage from the chain to the
tube itself is easy to see.

The Top Gun Chain Master is designed to
take advantage of existing frame fittings to
place a chain roller in the proper position
to control the upper-chain run. The Chain
Master comes with simple to follow

necessary to complete installation. It is made with only high quality components; even the
fasteners included are significantly stronger than those installed by the factory. By
installing the Chain Master, you will effectively
upgrade your lower left subframe bolt!

Many KLR-650 riders are unaware of this problem, but even street-only riders will benefit
from this protection. We gave a Chain Master to an experienced rider associated with a
major motorcycle publication for testing. During a stop, he struck up a conversation with a
fellow rider who happened by on another KLR-650. The conversation soon turned to our
product, and the other rider commented that he didn’t think the KLR needed a chain
roller. After a quick explanation of its benefits by our test rider, they walked over to the
other rider’s KLR, only to find that the vent-tube cover had already been torn off!
