Big bore kx125

explode64 · 08-21-2008

Has any one made a 144 or 133 cc kx125? Im looking for a 58mm piston and wondering what others have used

I did the 134, but it uses a 56mm piston and it could be purchased from wiesco

My '02 kx125 used a 56mm WISECO 719M05600 1998 pro light piston with a stroked motor. worked great. I didn't do it, I bought the bike that. I roughly measured the stroke and it sort of was about 1.5mm. I think WISECO also make a 58mm piston.
