    Going to change the piston on my SMR 510 soon and can't seem to find the needle bearing anywhere (the one under the piston)? OEM has it but I would have to buy the entire connecting rod assembly for like 400€. (Going to do that if my rod has any movement when I take it apart)

    Doesn't the needle bearing need to be replaced every time with piston like in 2 strokes?
    An OEM or aftermarket part number would be much appreciated as well.

    Again, manual says nothing about this. There isn't a single image of the bearing in the manual or google so I begin to wonder if 4-strokes even have needle bearings.

    Just watched couple videos about Yamaha and Kawasaki dirt bike rebuilds and neither had a needle bearing. This might seems like a dumb post but I just want be ready for everything before I start disassembling.

    Thanks for confirming. Found it odd that the website that sells the piston, sells needle bearings only for 2-strokes and I've only worked with 2-strokes before :D

    The Connecting Rods pin end is bushed.
    It's showing the pin bushing in your picture.
