Solid steel construction. Makes installing circlips an ABSOLUTE breeze without any chance of damaging or losing the circlip! For most all 2-cycle engines with 15mm piston pin, i.e. KZ / IZZ, Honda CR125, Rok Shifter, Rotax Max, TM K9 / KZ10 / R1 / R2, YZ125, KX125, RM125, etc.
NOTE: SLIGHT mod may be required if circlip bottoms out before compressing and sliding through the sleeve. 1st Option: clip off a bit of the end of the circlip to allow it to compress further. 2nd Option: grind the end off one of the 4 fingers slightly to allow the clip to overlap while pressing through the sleeve.
