Every motorcycle owner should learn some basic motorcycle maintenance. I think replacing a motorcycle battery is both an easy and important job to be able to do. Just like any other vehicle, a motorcycle will need a fresh battery at some point. Even using a battery tender we have to replace our batteries every two years. Being able to replace it yourself will save you time and money.
Removing a battery is a pretty simple process on a motorcycle, but it can vary from bike to bike so always check your service manual.
How to Remove Motorcycle Battery
1. Remove the seat.
2. If equipped with security system siren, turn the ignition switch ON with the handsfree fob
present to disarm the security system. I do not have a security system. Make sure you check your owner’s manual. The above information is all my owner’s manual shows.
3. Loosen bolt and remove the negative battery cable (black) from battery negative (-) terminal.
4. Loosen bolt and remove the positive battery cable (red) from battery positive (+) terminal.
5. Lift battery from battery box within oil tank cavity.
Installation and Connection
Do not overtighten bolts on battery terminals. Use the recommended torque values. Overtightening battery terminal bolts could result in damage to battery terminals.
Connect positive (+) battery cable first. If positive (+) cable should contact the ground with negative () cable connected, the resulting sparks can cause a battery explosion, which could result in death or serious injury. Do not allow positive (+) battery cable to contact the ground with negative (-) cable connected. Resulting sparks can cause a battery explosion, which could result in death or serious injury.

1. Place the fully charged battery into the battery box located within oil tank cavity, terminal
2. Attach battery positive cable (+) (red) to battery positive (+) terminal.
3. Tighten fastener to 60-70 inch lbs (6.87.9 Nm).
4. Attach battery negative cable (black) to battery negative (-) terminal.
5. Tighten fastener to 60-70 inch lbs (6.87.9 Nm).
6. Apply a light coat of petroleum jelly or corrosion retardant material to both battery terminals.
7. Install seat. After installing the seat, pull upward on the seat to be sure it is locked in position. While riding, a loose seat can shift causing loss of control, which could result in death or serious injury.
