Bleeding the Brakes on a 2011 Kawasaki KLE650 Versys
Shop parts for a 2011 Kawasaki KLE650 - Versys Motorcycle.
The 2011 Kawasaki KLE650 Versys stops with hydraulic disc brakes at both ends, which means the front lever and the rear pedal each push fluid from a master cylinder through a line to a caliper. Because both systems are hydraulic, both can be bled in a home garage with hand tools. Some 2011 Versys models left the factory with ABS; if your bike carries the ABS badge, the general procedure below still works for a routine fluid refresh, but there is an important exception covered later. This guide walks you through a full flush and air removal on the Versys, from setup to a low-speed test.
What You Are Actually Doing
Bleeding does two jobs at once. It pushes old, moisture-contaminated fluid out of the lines and calipers, and it carries trapped air out ahead of it. Air is compressible, so any bubble in the system turns lever travel into squish instead of clamping force. Old fluid is a slower problem: brake fluid absorbs water from the air over time, and water lowers the fluid’s boiling point. Under hard, repeated braking—think a long mountain descent loaded with luggage—that can boil into vapor and give you a lever that goes soft exactly when you need it most. Many riders on the Versys refresh fluid on a regular interval even when nothing feels wrong.
Symptoms That Call for a Bleed
- A lever or pedal that feels spongy, or that pulls noticeably closer to the grip than it used to.
- Fluid in the reservoir that looks dark, cloudy, or has visible sediment.
- Any recent work that opened the hydraulic system: new lines, caliper service, master cylinder repair, or a reservoir that ran dry.
- A lever that firms up after a few quick pumps—a classic sign of air in the line.
Tools and Supplies to Collect First
- Fresh brake fluid of the type marked on your master cylinder reservoir cap, from a sealed container. Do not substitute a different type.
- A box-end wrench that fits the bleeder valve snugly.
- Clear tubing that fits tightly over the bleeder nipple, plus a catch bottle.
- Rags or shop towels, and a syringe or turkey baster for lifting old fluid out of the reservoir.
- The correct driver for the reservoir cap screws.
- Optional but helpful: a one-way check-valve bleeder or a vacuum bleeder, which makes a solo job much less fiddly.
Setting Up the Versys
Get the bike upright and stable on a stand before you touch anything. For the front circuit, turn the handlebar so the reservoir on the master cylinder sits level—an angled reservoir will spill. Lay rags over the tank, the plastics around the bars, the instrument cluster, and anything painted below the reservoir and calipers. Brake fluid attacks paint and many plastics on contact, so wipe up any drip immediately and rinse the area with water if it reaches a painted surface. Work in a well-ventilated space and keep the fluid container capped when you are not pouring.
Bleeding the Front Brake
- Remove the reservoir cap and diaphragm. Use the syringe or baster to draw most of the old fluid out, but stop before the reservoir is empty—never let it run dry, or you will pull air straight into the line.
- Top the reservoir up with fresh fluid from the sealed container.
- Push the clear tubing onto the front caliper bleeder valve and route the other end into the catch bottle, with the bottle positioned so the tube end stays submerged.
- Squeeze the front lever slowly and hold it. With the lever held, open the bleeder about a quarter turn. Fluid and any air will push out through the tube.
- Close the bleeder before you release the lever. Releasing with the bleeder open draws air back in through the nipple.
- Repeat squeeze, hold, open, close, release. Check the reservoir level every few cycles and top it off so it never drops low enough to gulp air.
- Keep going until the fluid coming through the tube is clean and free of bubbles, then close the bleeder snugly—firm, not overtightened.
- If your Versys has two front calipers, bleed each one in turn, one at a time, topping off between them. As a general practice, start with the caliper farthest from the master cylinder and work toward the closest.
Bleeding the Rear Brake
- Open the rear reservoir and remove most of the old fluid with the syringe, again leaving fluid above the port.
- Refill with fresh fluid and fit the clear tubing over the rear caliper bleeder, routing it into the catch bottle.
- Press and hold the brake pedal, open the bleeder a quarter turn, then close it before releasing the pedal.
- Repeat until the fluid runs clean and bubble-free, watching the reservoir level throughout and topping off as needed.
- Finish by closing the bleeder snugly without overtightening.
Finishing and Verifying the Job
Fill each reservoir to the level marking, reinstall the diaphragm and cap, and wipe down every surface you touched. Look closely at the bleeder valves and at the banjo fittings at the master cylinder and caliper for any weeping or dampness—a wet fitting means something is not seated properly. Then check feel: the lever and pedal should be firm and consistent, and should not slowly sink while you hold steady pressure. Spin each wheel to confirm the brakes are not dragging. Finally, ride at low speed in a safe, empty area and test the brakes gently before trusting them in traffic.
When to Stop and Take It to a Shop
If the lever will not firm up after several honest bleeding attempts, if it only firms after pumping, or if bubbles keep appearing no matter how long you work, something else is wrong—typically air entering at a fitting or a failing master cylinder seal. Fluid weeping from the master cylinder or caliper also ends the home job. On an ABS-equipped Versys, a routine flush through the caliper bleeders is fine, but if the reservoir ran dry, or the ABS unit or its lines were disconnected, air may be trapped inside the ABS unit itself. That requires a dealer-level procedure or diagnostic tool, and the bike should go to a shop rather than be ridden.
