How To Fit Heated Grips To Your Motorcycle

Cold hands can make a motorcycle ride uncomfortable and reduce your ability to operate the controls smoothly. Heated grips provide direct warmth through the handlebar, making early commutes, winter touring and long regional rides more manageable. Learning how to install heated grips is a practical job for many home mechanics, provided the wiring and controls are handled carefully.

The process usually involves removing the existing grips, fitting the heating elements or heated grip assemblies, routing a fused power supply and checking that the throttle still moves freely. The exact method varies between motorcycles, so always compare the kit instructions with your model’s service information before cutting wires or loosening control housings.

Choosing A Compatible Heated Grip Kit

Start by checking the handlebar diameter and the length of the original grips. Most motorcycles use a 22 mm handlebar, although the throttle tube and left-hand bar may require different internal dimensions. Some kits replace the complete grips, while universal heating elements fit underneath separate rubber grips.

Select a kit with a suitable wattage for your motorcycle’s charging system. Smaller commuter bikes may have limited spare electrical capacity, while touring motorcycles generally provide more reserve. Look for a waterproof switch, quality connectors, an inline fuse and wiring long enough to reach the battery without stretching across moving parts.

Preparing The Motorcycle And Work Area

Park the motorcycle on a stable surface with the ignition switched off. Allow the engine and exhaust to cool, then disconnect the negative battery terminal before working on the electrical system. A paddock stand is helpful, but it is not essential if the motorcycle is secure and upright.

Australia’s riding conditions make preparation especially worthwhile. A Sydney rider may use heated grips during damp winter mornings, while a Melbourne commuter can encounter cold, wet weather even after a mild afternoon. Riders travelling through Tasmania, the Snowy Mountains or inland areas should also allow extra time for low temperatures and wind chill.

Gather the following before starting:

• Heated grip kit and installation instructions
• Basic screwdrivers, hex keys and side cutters
• Multimeter, electrical tape and cable ties
• Contact cleaner and suitable grip adhesive

Keep these safety checks in mind:

• Disconnect the negative battery lead first
• Keep the ignition key away from the switch
• Support loose control housings during removal
• Protect painted surfaces with a clean cloth

Clean handlebars and controls help the new grips seat correctly. Avoid using excessive force on switchgear, mirrors or brake components, as cracked housings can admit water and create future electrical problems.

Removing Controls And Routing Wiring

Remove the bar-end weights, handguards or other parts that prevent the original grips from sliding off. On the throttle side, take care not to pull or kink the throttle cables. The left grip may be bonded firmly to the bar, so carefully cutting the old rubber with a sharp blade is often safer than twisting the control assembly.

Before fitting the new parts, identify a route for the wires. They should follow the handlebar and frame without interfering with steering movement, the throttle, front brake lever or suspension. Turn the handlebars fully left and right while checking for tension. Leave enough slack for full steering lock, but avoid loose loops that could catch on a lever or sharp edge.

The controller is commonly mounted near the left switchgear or below the instrument cluster. Choose a position where it can be operated with a gloved hand without blocking the view of warning lights. Australian riders should also consider rain exposure, dust on unsealed roads and the likelihood of parking outdoors.

Fitting The Grips And Connecting Power

Test-fit each heated grip before applying adhesive. The throttle grip must not bind against the switch housing or bar-end weight. Twist the throttle open and release it several times; it should snap closed cleanly under spring tension. If it drags, correct the spacing before continuing.

Apply the recommended grip adhesive sparingly and slide the grips into position while it is still workable. Do not use too much product, as it can push into the throttle housing or prevent the grip from sitting fully home. Allow the adhesive to cure for the period specified by the manufacturer.

Connect the positive supply through the supplied fuse and, preferably, a switched source that turns off with the ignition. A relay-controlled circuit is a good option where the kit draws significant current. Connect the earth firmly to the battery negative terminal or a verified chassis ground, and use sealed connectors wherever possible.

Testing Heat And Reassembling Controls

Reconnect the battery and switch on the ignition without starting the engine. Confirm that the controller illuminates and that both grips warm evenly. Heat may take several minutes to become noticeable, particularly in cool weather, so avoid judging performance immediately after turning them on.

Start the motorcycle and check the charging voltage with a multimeter if one is available. Heated grips can place extra demand on the alternator, especially when combined with auxiliary lights, phone chargers or heated clothing. The battery should not be allowed to discharge during normal use, and the fuse should be replaced only with the specified rating.

Run through a final function check before securing the wiring:

• Turn the bars from lock to lock
• Open and release the throttle repeatedly
• Operate the brake and clutch levers
• Check that no wire touches hot or moving parts

Secure the loom with cable ties, leaving flexible sections where the handlebar moves. Trim tie ends neatly and refit bar-end weights, handguards and switch housings. If a grip rotates, a wire becomes tight or a control feels different, stop and correct it before riding.

Riding Legally And Maintaining The System

Heated grips are generally a straightforward comfort accessory, but motorcycle modifications still need to comply with applicable state or territory requirements. Rules and inspection practices vary across Australia, including New South Wales, Victoria, Queensland and Western Australia. The installation must not obstruct controls, conceal required indicators or create a dangerous wiring fault, and a roadworthy inspection may identify poorly secured equipment.

Use the lowest effective heat setting once your hands are comfortable. This reduces electrical load and helps prevent premature wear to the heating elements. Switch the grips off when stopping for fuel or parking, particularly if they are connected to a permanently live circuit.

Inspect the grips and wiring during routine servicing. Look for cracked insulation, loose connectors, water ingress and cable ties that have loosened from vibration. If the controller fails, check the fuse and earth connection before replacing parts. Uneven heating can indicate a damaged element or a poor connection rather than a defective battery.
