Way too big for a PW50, but I'm not using kx65 forks, I'm runnig KTM 65sx forks which are even longer. My buddy runs the KX bits though, and they would chopper out a PW no question.
No no Not a PW50... A PW80... I did install a KTM 65SX rear shock... Raised the rear some 4 inches... The PW80 has a 14 inch front wheel and 590mm forks from axle to fork caps. (Unloaded)... I was looking a the KX65 because they have front disk brake and hopefully better forks... Luis
