Normal steel cage needle rollers. These are heavy needles compared to the swing arm.

Here can be seen that the bearings are in a cage,brown in colour. In my opinion I'd rather see the cage not there and the space that the cage takes up,being taken up with grease instead. It should disintegrate with petrol where upon I can re fit the needles and pack with said grease. Is Yamaha being a cheapskate?
