Anyone have a clue as to why Suzuki went with wheel bearings that are different? LH and RH. One is a metal constructed enclosure but open on the back side and one is the usual plastic enclosed bearing but it's also opened on the back side exposing the ball bearings. I'm not familiar with Suzuki at all and was just curious.

Also, on the rear swing arm bearings, the 2 small needle roller brearings, any tricks to remove / install ? Thanks.
