Rox Speed FX AV2 S/P Anti-Vibration Handlebar Risers

HERE.

Suggested retail price is $149.95 as of September 6, 2007


INTRODUCTION

Two things that most single cylinder (thumper) owners desire are low handlebar vibration and adequate handlebar rise.

Vibration can be annoying and numbing at times, and reaching way down for your grips while standing gets old very quickly.

The Rox Speed FX AV2 S/p Antivibration Risers are designed to solve both of these problems for all dual sport motorcycles.

When I bought my 2001 Kawasaki KLR650, the vibration transmitted to my hands was actually numbing my fingertips after a 45 minute ride. To solve this problem, I replaced the stock handlebar with a Pro Taper Contour CR High Fat Bar and a pair of foam cruiser grips.

This Pro Taper handlebar is 1 1/8' at the handlebar clamp and tapers down to a normal 7/8" at the grip area. Along with the cruiser grips I solved most of the vibration issues but created another- a larger diameter grip that is not as easy to manipulate while off road. And I still had vibration I would like to see reduced.

The Pro Taper Contour bar required the use of aluminum adapters to secure the 1 1/8' bar to the 7/8 tree. While these added a small rise, they also brought the bar back towards the rider a bit.


INSPECTION & INSTALLATION

I received the AV2 S/P risers as shown below-

Image

After removing the risers from the packaging, I took a closer look. The machining looks precise & the gunmetal finish was excellent-

Image

The upper & lower sections of the risers are seperated by a firm but flexable bushings. The tension on these bushings can be adjusted to the riders preference by tightening or loosening the adjuster hardware-

Image

Here is my KLR650 before I began the installation-

Image

You can see in this view that the Pro Taper adapters do a good job of adapting the bar to the tree, but also move the bar out towards the rider-

Image

Comparing the Rox AV2 S/P risers to the Pro Taper adapter shows a dramatic difference. The AV2 risers are rated at a 2 inch rise-

Image

I began my installation by removing the Pro Taper bar adapters and installed the Rox AV2 risers using the stock bar caps. I barely snugged the caps down so that I could adjust the risers forward, aft & sideways-

Image

Then I positioned the left riser in a vertical postion, ( you may position the risers in a wide range to suit yourself ) I applied Loctite 242 to the cap bolt threads and tightened down the cap bolts with an allen wrench (recommended by Rox).

I used a strait edge to line the right riser up with the left and snugged down the right cap-

Here are the risers installed without the bar-

Image

Then I centered the bar in the risers and tightened the riser caps with an allen wrench (don't forget the Loctite!) -

Image

Here is a riders view-

With the bar installed there is plenty of room to access the ignition switch. As an added bonus, the steering stem nut is now very easy to get to.

One adjustment I had to make to my KLR650's controls was to reposition the throttle cables. I have a tall Kawasaki widsheild installed and with the risers installed, the cables were hitting the windsheild when I moved the handlebar fully left. After repostioning the cables, clearance was no longer an issue on either side.

I did not have a stock KLR650 windsheild to check the clearance, but would not think it would be an issue as it is much shorter.

Here are the left controls when fully turned to the locks-

INSTALLED COMPARISONS

In the photo below is my KLR650 with the Pro Taper Adapters installed. I have added a small white rectangle to the photo to show the difference in height when compared to the Rox AV2 S/P Risers.

The Rox AV2 S/P Risers show a considerable rise improvement-

CONCLUSIONS

My evaluation continued with a test ride in my normal riding gear. I felt it most important to wear my regular riding gloves so that I could feel any difference in vibration levels.

So I headed out for my ride & exited my neighborhood standing on the pegs with the greatest of ease. I could not get over how much more comfortable I was while standing up. It was much easier to reach and manipulate all of the controls.

Next was the vibration tests. Having no scientific way of analyzing this, I decided that riding my KLR650 at varying rpm ranges & speeds, as well as normal street riding should let me feel any difference.

I did feel quite a reduction in vibration at all speeds! This was quite remarkable, as I thought I had previously minimized vibration by use of the fat bar & foam grips.

This means that I can install a set of thinner gel grips and probably still be at a lower vibration point than before.

Another important aspect of these risers is safety. In the event of accident or off that results in the rider hitting the handlebar, the Rox Speed FX AV2 risers will pivot forward, thus reducing impact with the bar.

This is a FANTASTIC set of risers! I highly recommend a set of these risers to anyone looking for a solution to vibration and rise problems.

I am giving the Rox Speed FX AV2 S/P Risers a 10 out of 10!
