Fits all years of the KLX140. There are no installation instructions, but if you can replace your piston, you can install this kit. If you don't have any experience working on your engine, we highly recommend having a professional technician install this kit or, at a minimum, purchasing the shop manual for your bike available from your local Kawasaki dealer. The parts are installed in the same manner as the OEM parts. Your bike will also need to be re-jetted to provide the additional fuel this big bore kit will require to run properly.

We highly recommend professional installation and tuning. Have any questions or concerns? Please send us a message and we will gladly help with any questions you may have.
