This is one of our latest kit to turn your KLX110 into an absolute beast! The kit includes an all aluminum ceramic plated 67mm cylinder with a skirt. This cylinder is lighter than a steel sleeved aluminum cylinder, reduces friction (increasing power), improves sealing, and provides better heat transfer (runs and cools down quicker). Unlike other kits, our head gasket kit also includes a head o-ring set and exhaust gasket so you don't have to re-use your old ones or make a trip to your local dealer to get new ones and spend more money. These are high quality parts and definitely will dramatically increase the power and fun factor on your bike!

Installation requires engine disassembly and case boring. Therefore, we highly recommend a professional technician install this kit and the cases bored by a reputable machine shop. If you plan on installing the kit yourself, we highly recommend purchasing the shop manual for your bike available in this section or from your local Kawasaki or Suzuki dealer. The parts are installed in the same manner as the OEM parts. Also, while the engine is disassembled, you might consider the following options:

- 4th Gear Shift Drum.
- 2008 Kawasaki Output shaft - a must if you have a 2007 or older model.

**IMPORTANT NOTE FOR Z125's: It is recommended that a professional technician make sure the bike is tuned properly after install. An aftermarket fuel controller is required and possibly an autotune will be needed to prevent a lean condition and damage to your engine. Additionally, a performance exhaust is also recommended as the stock exhaust is restrictive and may cause your engine to run hotter.
