Review on 🔧 Piston Ring Compressor KIT69: Efficient Tool for Easy Piston Maintenance by Dejuan Stott

Used on my KTM 520 RFS engine. This is a 97mm piston. You can put the piston on the rod and then install the cylinder. There is enough room to pull it out once the rings are in. This way you don't have to put the piston in the cylinder first and then in the rod. This will work with almost anything from above as long as the piston diameter isn't too far above the maximum ring size.
