NEW! ALSO FITS 2010 KLX110's / 165cc KIT BY TRAILBIKES

165cc Big Bore Kit: - All aluminum ceramic plated 64mm cylinder - Lightweight high compression 64mm piston with rings, pin, & clips - Head gasket kit - includes the cylinder head o-ring set and an exhaust gasket. This is our most affordable 165 bore kit for the KLX110. Works great with your KLX stock head, our Race Head, or our new V2 Race Head. The kit includes an all aluminum ceramic plated 64mm skirtless cylinder which will increase your engine displacement to 165cc.  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). Additionally, our head gasket kit 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.  NOTE- CASES MUST BE BORED TO ACCEPT BIG BORE CYLINDER
