How Much Does It Cost To Rebuild A Motorcycle Transmission? (With 4 Examples)

Motorcycle transmissions are part of what makes riding so satisfying. Shifting through the gears effortlessly and hearing your engine rpms rise is part of what makes motorcycling great.

Unfortunately not all transmissions will last the lifetime of your motorcycle. So how much should a motorcycle transmission rebuild cost? Well the answer is going to depend what type of bike you own. Certain bikes like Kawasaki ZX6Rs, a high performance middle weight sport bike, will cost more to have a transmission rebuilt than a dirt bike.

Dirt bikes racing in motor cross are ran hard and their engines and transmissions are designed to be rebuilt. In fact a transmission might only last one season of racing between being rebuilt.

A street legal sport bike’s transmission is designed to last longer than a purpose built racing bike.

How Long Do Motorcycle Transmissions Last?

With proper maintenance a cruiser, touring, and sport bike transmission should last the life of the motorcycle. In fact its not uncommon for motorcycles with 100k miles to still have the original transmission.

Dirt bikes have a shorter life time than road bikes due to their higher level of abuse that they take. The average dirt bike lasts around 600 hrs or somewhere around 12,000 miles. The transmission should last this long.

Racing whether track or on the dirt will reduce your transmission’s life. This is because racing spins the gears faster and gets the transmission fluid hotter. It won’t ruin your motorcycle, but higher speeds and torques will reduce transmission life.

The best way to keep your motorcycle’s transmission running well is to change the fluid at the appropriate intervals.

Despite proper maintenance a transmission can fail. This can be caused by a manufacturer defect, such as a fatigue failure in a gear, or other issues. When parts break inside the transmission it is time for a rebuild.

How To Tell If Your Transmission Needs To Be Rebuilt?

So how do you know when your transmission is the problem with your motorcycle? Well there are several key signs to look for that will determine if its the issue.

  1. Lack of response: The transmission refuses to shift gear
  2. Leaking transmission fluid
  3. Grinding sound or shaking when transmission is operating
  4. Burning smell coming from transmission
  5. Won’t shift into gear
  6. Loud operation in neutral

If you’re experiencing any of these symptoms, it might be worth looking into refreshing the transmission. So how much should rebuilding the transmission cost?

How Much Does A Transmission Rebuild Cost on A Sport Bike?

It also depends on the brand of motorcycle you own. A Kawasaki, Yamaha, Honda, or Suzuki will be much cheaper to rebuild than a Ducati. In fact one owner was quoted $3500 for a transmission rebuild on a 2014 Hypermotard (supermoto styled motorcycle), and only $400 was for parts.
