What Motion Pro cables are and who uses them
Motion Pro cables are control cables made by Motion Pro, a company that manufactures motorcycle and powersports parts. These cables connect your hand controls — throttle, clutch, brake — to the engine and mechanical systems on your bike. When you twist the throttle grip or pull the clutch lever, the cable transmits that movement to open the carburetor, engage the clutch, or set up the brakes.
Motion Pro is one of several cable manufacturers in the aftermarket parts space. Riders replace factory cables when the originals wear out, fray, or stop moving smoothly. Some riders also swap cables when customizing their bike's geometry — for example, if you raise the handlebars, the factory cable may no longer reach properly, and you need a longer one.
The company also makes related tools and maintenance products, like cable lubricants and cable routing hardware. Motion Pro cables come in different lengths and configurations depending on your motorcycle model and what you're controlling.
Key Takeaways
- Motion Pro cables are replacement control cables for motorcycles that transmit movement from your hand controls to the engine and brake systems.
- You typically need to replace a cable when the original frays, sticks, or breaks, or when you modify your bike's geometry and the factory cable no longer fits.
- Motion Pro makes cables in different lengths and styles — throttle, clutch, and brake — so you need to know your bike's year, make, and model to order the right one.
- Installation usually takes 30 minutes to an hour and requires basic hand tools; the cable slides into a housing and connects at both ends with barrel fittings.
Types of Motion Pro cables and what they control
Motion Pro makes three main cable types for motorcycles: throttle, clutch, and brake. A throttle cable runs from your right hand grip to the carburetor (or fuel injection body on newer bikes) and opens the throttle when you twist the grip. A clutch cable runs from your left hand lever to the clutch basket and disengages the engine from the transmission when you pull the lever. A brake cable runs from your hand lever or foot pedal to the brake caliper and squeezes the brake pads when you explore pressure.
Some bikes also use cables for choke control, idle adjustment, or other functions. Motion Pro makes cables for all these applications. The cable itself is a steel wire wound tightly inside a plastic or metal housing. The housing keeps dirt and moisture out and guides the wire smoothly from one end to the other.
Motion Pro also sells universal cables that you can cut to length and route however you need, plus pre-made cables built to fit specific motorcycle models. If you know your bike's year, make, and model, you can usually find a cable designed to fit it without modification.
When to replace a Motion Pro cable
A cable needs replacement when it no longer moves smoothly or when the wire inside breaks. Common signs include a throttle that sticks or returns slowly, a clutch that feels rough or won't fully disengage, or a brake that drags. You might also see fraying at the cable ends or visible rust on the wire.
Cables also wear out faster in wet climates or if you ride in salt water or mud. The housing can crack, allowing moisture to corrode the wire inside. If you've customized your bike — raised the bars, lowered the seat, or changed the frame geometry — the factory cable may no longer reach properly, and you'll need a longer or shorter one.
Some riders replace cables as preventive maintenance every few years, especially if they ride frequently. A broken cable while riding can leave you without throttle control or braking, which is a safety hazard.
How to measure and order the right cable
To order a Motion Pro cable, you need your motorcycle's year, make, model, and engine size. This information tells you which cable length and routing path the bike uses. You can find this on your registration, in your owner's manual, or on the bike itself — usually stamped on the frame or engine.
If you're replacing a cable that's already on your bike, you can measure the old one. Lay it out straight and measure from the center of the barrel fitting at one end to the center of the barrel fitting at the other end. Write this number down and add it to your order notes.
If you've modified your bike and need a custom length, measure the path the cable will take — from the control lever to the component it operates — and add a few inches for slack. Motion Pro sells universal cables that you can cut to length, or you can contact their customer service with your measurements and they can recommend a pre-made cable close to your needs.
Installing a Motion Pro cable yourself
Installing a cable is a straightforward task that takes 30 minutes to an hour. You'll need basic hand tools: a wrench or socket set to remove the barrel fittings, a screwdriver to remove any cable guides or clips, and possibly a small amount of cable lubricant.
Start by removing the old cable. Disconnect the barrel fitting at the control end (the lever or grip) by unbolting it or unscrewing it, depending on your bike's design. Then disconnect the barrel fitting at the component end (the carburetor, clutch basket, or brake caliper). Slide the old cable out of its housing and set it aside.
Thread the new cable through the existing housing, starting from the component end. Make sure it seats fully in the housing at both ends. Connect the barrel fitting at the component end first, then route the cable along the frame following the path the old cable took. Connect the barrel fitting at the control end last. Adjust the cable so there's a small amount of slack — usually about a quarter-inch of play at the lever or grip — and tighten all bolts.
If the cable doesn't move smoothly, the housing may be kinked or the cable may not be seated properly in the barrel fittings. Disconnect and reconnect, making sure the cable wire is fully inserted into each fitting before tightening.
Maintaining your Motion Pro cable
A cable lasts longer if you keep it clean and lubricated. Spray cable lubricant into the housing every few months, especially if you ride in wet or dusty conditions. Motion Pro makes a cable lubricant designed for this purpose, but general-purpose light machine oil also works.
Check your cables visually every month or two. Look for fraying at the ends, cracks in the housing, or visible rust on the wire. If you see any of these, plan to replace the cable soon. Also check that the barrel fittings are tight and that the cable has the right amount of slack — too much slack means slow response, and too little means the cable may pull tight and stick.
Store your bike in a dry place if possible. Moisture is the main enemy of cable life. If you ride in salt water or salt spray, rinse your bike afterward and dry the cables with a cloth.
Motion Pro cables versus other brands
Motion Pro is one of several aftermarket cable manufacturers. Other common brands include Barnett, Magnum, and OEM (original equipment manufacturer) cables from your bike's maker. Motion Pro cables are generally mid-range in price and widely available through motorcycle parts retailers and online.
OEM cables are made by your bike's manufacturer and are may provide to fit your specific model, but they often cost more. Aftermarket cables like Motion Pro are usually cheaper and come in more length options, which is useful if you've modified your bike. Some riders prefer one brand over another based on feel or durability, but all major brands are reliable if installed correctly.
The main difference between brands is availability and price, not quality. If you can't find a Motion Pro cable for your bike, a Barnett or Magnum cable of the same type and length will work just as well.
Frequently Asked Questions
Can I use a Motion Pro cable on a bike it wasn't designed for?
Only if the length and barrel fitting sizes match. Cables are not universal — the length, routing, and fitting type must suit your bike's geometry. Measure your old cable or contact Motion Pro with your bike's year, make, and model before ordering.
What does it mean if my throttle cable feels sticky?
The cable housing is likely kinked, the wire is corroded inside, or the barrel fittings are too tight. Try lubricating the cable first. If that doesn't help, the cable probably needs replacement. A sticky throttle is a safety issue and should be fixed before you ride.
How long does a Motion Pro cable last?
A well-maintained cable typically lasts two to five years, depending on how often you ride and the climate. Cables in wet or salty environments wear out faster. Regular lubrication and inspection can extend the life.
Do I need special tools to install a Motion Pro cable?
No. Basic hand tools — wrenches, screwdrivers, and pliers — are all you need. A small amount of cable lubricant helps the new cable slide smoothly into the housing, but it's not required for installation.
What if my Motion Pro cable breaks while I'm riding?
If the throttle cable breaks, you lose engine control and must coast to a stop. If the clutch cable breaks, you can still ride by shifting without the clutch, though it will be rough. If the brake cable breaks, you lose braking power on that wheel. Any broken cable is a safety hazard — do not ride the bike until it's replaced.
