TBParts - 165cc Big Bore Kit
DRZ110 - KLX110 - Z125

We had a takegawa 143 and switched to this head and piston with the TBWO 475 stroker crank and V1 race head. Wow what a major difference and its affordable.Getting the hole shot makes the race a little easier. Make sure if you go to this setup you get the compression release. You"ll need it.
