TBparts 60mm 143cc Big Bore Kit: An all aluminum ceramic coated 60mm cylinder. No case boring required, bolt on! 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). Paired with our Lightweight, 60mm high compression lightweight piston (7mm larger than the stock 53mm piston) and you have a great base for big power gains of over 50%. Comes with rings, pin, & clips (will safely run on pump gas, 90-93 octane). Top end gaskets are also included.
Key Features
This kit does not require boring of the case – simply bolt on and go! 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.

"Great product with everything you need to make klx110 eat. Put this on a stock 2003 to wake it up. If you have an older bike make sure to buy the dowel spacers for the head bolts between the lower end and cylinder. Mine would not come out of the old cylinder head after soaking in PB then torching."
"It was good"
"works perfectly on my 2004 Suzuki DRZ 110"
"Worked perfect no flaws has plenty of power and had quick delivery"
"Fast shipping"
"Even with the Stock carb and basic jetting increased the performance by double"
"Can’t believe the cost to big bore a 110 is so affordable. Picked up a basket case Klx with a roached piston and the cost of a complete 143 big bore kit was only about $25 more than a stock rebuild."
"Recently bought a klx110 with bad rings bought this kit was shipped quickly and fit perfectly!"
"Work great"
"power!!"
