Until recently, the Intruder series filled the role as Suzuki's line of cruiser motorcycles. Featuring a blend of modern styling and classic lines, these large-displacement V-twin motorcycles drew a tremendous following of riders. Unfortunately, Suzuki was criticised for placing the battery at the bottom of the Intruder's frame, making electrical modifications and routine battery replacement a complicated task. While it will still take up to an hour to complete the task, having a motorcycle stand can simplify the process.
Park the motorcycle on a smooth, level surface and raise the rear wheel off of the ground using a motorcycle stand.
Open the battery box, which is hidden at the rear of the motorcycle's frame. Reach under the battery box with one hand and lift it upwards to relieve the pressure on the battery box's mounting bolts. Using a screwdriver, loosen the lower mounting bolts and unscrew the upper mounting bolts completely. Lower the battery box by pivoting it against the loosened lower mounting bolts.
Unscrew the battery terminal bolts with a Phillips head screwdriver, disconnecting the negative terminal first followed by the positive terminal. Set the motorcycle's terminal lead wires away from the frame and battery box. Pull the battery out of the battery box.
Place a fresh, fully-charged battery into the battery box and reconnect the terminal lead wires. Connect the positive terminal first followed by the negative terminal. Tighten the terminal bolts with a Phillips head screwdriver.
Pivot the battery box upwards against its lower mounting bolts and hold it in place with one hand. Insert and tighten the upper mounting bolts with a socket wrench. Tighten the lower mounting bolts with a socket wrench.
Lower the motorcycle's rear wheel to the ground.
If you do not have access to a motorcycle stand, have the work performed by a qualified Suzuki technician.
Use caution when disconnecting the battery. A serious electrical shock or short-circuit can occur if the lead wires come into contact with the motorcycle's frame.
