I've always been a little surprised at how heavy my 08' SM feels, but when physically lifting it into the bed of my truck, or even when pushing/rolling it around, but I figured it was just the nature of my bike. However, recently I helped move a buddy's SM around and his was substantially easier to lift and push around. He also comment on my SM being heavier to lift and harder to push around. Anyone have any ideas as to what could be causing my bike to feel so heavy? As far as I know its a regular 08' SM, the only mod that I can think of that might cause a little extra weight is that the bike has a slightly larger battery than stock, but its only about a 1/4" larger than the stock one.
