Why You Need This: There comes a time in every vintage Honda motorcycle's life when an engine overhaul is in order. Fortunately, not all these occasions end in having to install new pistons. If the cylinders of your Honda CB175 / CL175 Scrambler / SL175 measure within the published service limits you can get away just fine with a hone and re-ring. Still, while you have the top engine and pistons apart, take a look at the wrist pins (gudgeon pins) that came out of your pistons. More than likely you will find that they don't look so hot with grooves worn in them from the connecting rod. The surface of your piston pin should be perfectly smooth, otherwise you have to replace it with a new one.

Many wrist pins on the market have the right diameter but are too short in length, causing the pin to float in the piston. This will lead the retaining clips to hammer loose resulting in serious engine damage. With our CMC piston pin kit you can forget about this problem, as it will fit perfectly inside your piston without leaving any unnecessary wiggle room.

Each kit is sold individually and includes one wrist pin with two "C" style retaining clips (these should be changed out every time they are removed). Our piston pins are designed for the original cast pistons found in the Honda CB175 / CL175 Scrambler / SL175 engine. They will work with NOS Honda and our very own CMC "Pulsar" oversize pistons as well.

You will need one wrist pin kit per piston, two kits per engine. Make sure to pick up a fresh pair of piston rings and an overhaul gasket kit to finish your rebuild right. If you do need to replace your pistons, our "Pulsar" oversize pistons kits are also available for your Honda CB175 / CL175 / SL175 engine complete with piston rings, wrist pin and retaining clips.

Installation Tip: Before installing the piston on the connecting rod, install one clip on each piston on the side that faces the cam chain. Oil the piston and wrist pin well upon assembly. Be extra careful not to drop the second clip in the engine during installation and make sure that the ends of the clip face 180 degrees away from the notch in the piston.
