How To Install Aftermarket R6 Levers

This guide was written by WTF Racing from Perth, Australia.

This how to guide will show you what you need to do to install an aftermarket set of brake and clutch levers onto your bike, or replace the existing ones.

The levers used in this How To are C-n-R Levers, a new brand on the market that are in competition with CRG, Pazzo, ASV, Titax and a few others.

Brake Lever

This is a simple swap.  Initially you start of with your existing brake lever, which (hopefully if you’ve set up your bike for yourself) should be in the correct position for your height and riding position.

Original Brake Lever

Simply remove the bolt which is holding the lever to brake master cylinder. This should simply require a nylon nut to be removed from the underside of the lever, while the bolt is being braced using a flat-head screwdriver.. Be careful, as if you drop the nut, you may have a hard time searching through the fairings, air-box, engine to find it again.  Remove the existing lever.

Brake Lever Removed

All you then have to do is put on the new lever, line up the holes, push through the bolt, and re-install the Nylon nut.  Make sure that there is sufficient lubricant to keep the brake lever operating smoothly.

Brake Lever Installed

Lever upgrade completed.  It will give you a slightly smoother operation, as will as giving you quick adjustability to move the position of the lever closer or further from the bar.

Clutch Lever

Original Clutch Lever

Firstly you will find that you are going to have to remove the two plugs for the switch on the underside of the Clutch lever, this is so that you will have access to the nylon nut on the bottom of the lever.  You will also have to loosen the lever mount on the bar, to be able to twist the lever around to easily see what you are doing.

Next you will be required to increase the Lever free play using the silver clutch lever adjustment bolt (See your user manual) until the cable is as loose as possible.  Align the gap in the back of the lever and the adjuster bolt and test if you can remove the cable from the adjuster bolt.  Hopefully you can.

If there isn’t enough free play, you will also have to loosen the clutch cable at the crank-case.  Please refer to your manual for your particular bike.

Loosen Cable

Once you have the free play, you should be able to remove the ‘hammer’ and cable from the clutch lever.

Once this is removed, you can loosen and remove the nylon nut, again being careful not to lose it in the fairings engine etc.  Once the bolt is removed, remove the lever.

Remove Clutch Lever

From the original lever, you are going to have to remove a small spacer in the bolt hole of the lever, and put it into the C-n-R Lever.  Re-grease the surfaces of the lever and mount ready for installation.

Replace and Grease

Place the lever into the lever mount, and re-align the holes before inserting the bolt.  It is positioned correctly when it becomes flush with the lever mount.  Replace the nylon nut and tighten.

Then, ensuring that the gap in the lever and adjustment bolt are aligned, first place the small ‘hammer’ on the end of the cable into the associated gap in the lever, before running the cable back down the aligned gaps within the adjustment bolt.

Install Lever and Bolt

Re-tighten the clutch adjustment at the crankcase.

Retighten Clutch Cable

Re-tighten the clutch free play adjustment bolt at the lever, until you have the desired free play as shown within your owners manual.

Finally, get on your bike, and reposition the angle of your clutch lever to that which is comfortable for your riding position.  Tighten the mounting bolt until the lever doesn’t rotate around the bar.

Lever Installed

Congratulations, you can now quickly adjust the distance of your clutch lever from the bar itself.
