CR125 (88-07) Rod Kit CR/NF

For the Honda RS125 NF4 it is impossible to find cranks or rod-kits. For this reason CR125 rod-kits, that have a 19mm instead of 18mm small-end, are often used for crank rebuilds. Afterwards you can use the NX4 piston but doing so requires modification of the cyclinder because the NX4 piston has a differnt compression hight. The simpler solution is to use a 14x19x17,1mm needle bearing, no other changes to the motor will then be necessary. You can find the 14x19x17,1mm needle bearing here:Needle Bearing 14mm (CR/NF)
