We've stood behind these products 100% since we opened in 2005. Best reviews received for a big bore kit hands down!


Trail Bikes 143cc (60mm) Bore Kit for KLX or DRZ 110's - 2002-Current

- NEW Ceramic coated all aluminum cylinder (no steel sleeve) 
- Lightweight aluminum high compression domed 60mm piston with rings, pin, & clips
- Head gasket kit - Now includes the cylinder head o-ring set and an exhaust gasket.

The all aluminum ceramic coated 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). This new cylinder along with a complete head gasket kit and domed piston set this kit apart from other similarly priced 143 kits on the market. Affordable and will make your KLX110 or DRZ110 a lot more fun to ride! High quality parts and requires no machining to the cases or other modifications - bolt on and go! If you have a 2009 or older model, also recommend the camshaft available in this seciton.

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 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.

Just right

Perfect bump in power, especially down low to help this 220lb get out of corners quicker. Fit and function is great and install was super easy with basic tools.
