So i have a 1995 KTM 300 Exc and ive read online that the pistons for that year are slightly different than the surrounding years. I also read that they were no longer manufactured. My question is where and how would i get a new piston and rings for my bike? ive been searching for a place for months now and still no luck so if anyone on here can direct me to a place that can, thjat would be great! Also the top of my piston says 72 mm stroke but this website says 73mm?
