There’s something incredibly satisfying about upgrading your motorcycle with high-quality components that enhance both performance and aesthetics. CNC Racing brake and clutch levers are exactly that kind of upgrade — a perfect fusion of form and function, delivering precision engineering and Italian design flair.

But if you’ve never swapped out your levers before, it might feel a bit intimidating. Don’t worry. This guide will walk you through the entire installation process, step by step. Whether you're riding a Ducati, MV Agusta, Aprilia, or any compatible bike, you’ll be able to complete this mod confidently with just a few tools and a bit of patience.

Why Upgrade to CNC Racing Levers?

Before we get into the how, let’s quickly look at the why — because knowing what you’re gaining makes the effort feel even more worthwhile.

CNC Racing levers are:

Precision-machined from billet aluminum, ensuring lightweight durability
Fully adjustable, allowing fine-tuned control for hand comfort and performance
Stylish, adding an aggressive, race-inspired look to your cockpit
Trusted in racing, used by professionals in MotoGP and WSBK

Now, let’s get our hands dirty (but not too dirty — this is a clean mod!).

Tools You’ll Need

Here’s what to gather before you start:

A set of Allen keys (hex wrenches)
Open-end or adjustable wrench
Needle-nose pliers
A clean cloth or towel to protect your tank and fairings
A bit of grease or lubricant
Your new CNC Racing levers, of course!

Safety First: Prepping for the Install

Before starting any mechanical work on your bike, take these basic precautions:

Turn off the engine and ensure the bike is cool.
Park on a stable surface and use a rear stand if you have one — stability is key.
Protect painted surfaces with a microfiber towel or cloth. Trust us, even a dropped bolt can leave a nasty scratch.

Once everything is in place, it’s time to begin.

Step-by-Step Installation: Brake Lever

Let’s start with the front brake lever. This one tends to be a little easier than the clutch, depending on your setup.

Step 1: Locate the Pivot Bolt and Lock Nut

You’ll see the brake lever is held in place by a pivot bolt at the top and a locking nut underneath. Use your Allen key to loosen the bolt while holding the nut steady with a wrench.

Step 2: Remove the OEM Lever

Once the bolt and nut are off, gently pull the lever away from the perch. Be careful not to tug or twist, especially around the brake light switch or master cylinder area.

Step 3: Inspect and Clean

Before installing the new lever, check the pivot point and clean out any old grease or debris. A tiny dab of fresh grease will help your new lever pivot smoothly and extend its life.

Step 4: Install the CNC Racing Brake Lever

Align the new CNC Racing lever with the mounting point. Insert the pivot bolt and tighten it down — snug, but not overtightened. Reinstall the lock nut underneath.

Test the lever: it should feel smooth and click into place with each adjustment notch. If it’s binding or too loose, double-check your install.

Step-by-Step Installation: Clutch Lever

Now onto the clutch side, which can be a little trickier due to the clutch cable or hydraulic mechanism (depending on your bike).

Step 1: Loosen the Clutch Cable (Cable Clutch Only)

If your bike uses a clutch cable, you’ll want to back off the tension adjuster near the lever to create slack. This makes it easier to slide the cable out.

For hydraulic systems, just skip to the next step.

Step 2: Remove the Pivot Bolt

Same as with the brake side — remove the pivot bolt and locking nut, then gently pull the OEM lever out. Keep an eye out for small springs or bushings.

Step 3: Swap the Cable or Piston into the New Lever

For cable clutches, hook the clutch cable into the CNC Racing lever just like it was on the OEM part.

For hydraulic clutches, carefully align the actuator pin (usually spring-loaded) into the master cylinder cup.

Step 4: Reinstall and Test

Insert the pivot bolt, reinstall the locking nut, and make sure everything is aligned and snug. If you backed off the clutch cable, re-tighten it to the correct tension now.

Pull the clutch a few times. It should feel crisp and smooth, with no sticking or excessive play. Adjust reach as needed using the CNC lever’s adjuster wheel.

Real-World Tip: Take a Short Ride and Recheck

After installing new levers, take your bike on a short test ride — preferably somewhere safe and quiet. Feel how the new levers respond under braking and shifting conditions. Are they comfortable? Do they feel too tight or loose?

Once you return, recheck all bolts for tightness. Aluminum levers can settle slightly after use, so a second torque check is smart.

Common Issues and Fixes

1. Lever feels too loose or wobbly?
Check if there’s a missing bushing or the pivot bolt isn’t fully tightened.

2. Clutch won’t engage fully?
Re-adjust cable tension or confirm hydraulic piston is seated properly in the master cylinder.

3. Brake light stays on?
You may need to slightly adjust the brake lever’s resting position so it disengages the brake light switch.

Why Riders Swear by CNC Racing Levers

One Ducati Monster owner, Marco from Los Angeles, upgraded to CNC Racing levers and was stunned by the improvement:

“The feel is immediate — more responsive, more ergonomic. Plus, they just look amazing. Installation was easier than I expected. Took me about 30 minutes total.”

That’s the magic of quality parts. It’s not just about aesthetics; it’s about enhancing the riding experience in small, meaningful ways.

Final Thoughts: Elevate Your Ride, One Lever at a Time

Installing CNC Racing brake and clutch levers isn’t just a cosmetic upgrade — it’s a functional, confidence-boosting improvement that puts more control and style in your hands. The process is straightforward, and once you’ve done it, you’ll likely find yourself wondering why you didn’t make the switch sooner.

So take your time, follow the steps, and enjoy the transformation. And remember: when you upgrade with premium parts like CNC Racing, you’re investing in both your bike and your riding experience.
