Do engine mounts affect performance?

Engine mounts do affect the engine performance of the motorcycle, and they can directly affect the handling performance of the motorcycle as well. If your motor mounts are worn-out, it can cause excessive vibration though the chassis of the motorcycle. This can lead to issues in handling as well as excessive wear on the seals connecting your motor to the rest of the drive train. If you have a transmission seal that keeps leaking, it is good practice to check your motor mounts for wear or cracks.

Can bad engine mounts affect the transmission?

Yes, a broken engine mount can affect the transmission because the engine is directly connected to the motor through a series of shafts and seals. If your motor is vibrating excessively because of a broken engine mount, this will cause an excessive amount of strain on the components connecting the transmission to the motor.

Are some motorcycle engine mounts better than others?

Yes, some motorcycle engine mounts are better than others. When considering purchasing motor mounts, you need to consider the material that the motor mount is made of. If you purchase a motor mount made of a softer material like aluminum, it is not going to be as ridged as a steel motor mount. Over time the aluminum mount will fail. A steel mount made of a good quality steel will be much more durable. Some motor mounts offer custom features, such as mounts for the ignition coil and / or motorcycle ignition switch.

The Risks of Driving with a Damaged Motor Mount

Your motorcycle mounts do the job of keeping your motorcycle in the frame of the bike. If you have ever ridden a bike with a broken or worn out motor mount, you know that there is a lot of extra vibration that can occur when you have a motor mount failure. This is a common issue with certain Harley Davidson® models.

The unbalanced motors that give Harley Davidson® that unforgettable sound also is responsible for all of that vibration traveling through the frame. This vibration can cause numerous failures if you are not maintaining your bike on a regular basis. Cracked or broken motor mounts, exhaust mounts, lost air cleaner bolts, broken carb manifolds. All of these issues are the result of all that vibration going through the frame and wreaking havoc on your bike.

How long do engine mounts last?

Vibration is the enemy of your motorcycle engine mounts and keeping a close eye on those mounts is a good practice. Making sure the mount bolts are tightened to spec and checking for hairline cracks or other signs of failure should be done a few times a year depending on how often you ride your bike. If you do notice a crack or the beginning of a failure, you should replace that motorcycle engine mount right away.
