Stock Honda piece is 2.021
Bearing cap O.D. on the Moose unit: 0.746
Bearing cap on the OEM unit: 0.667.
500 swingarm on the left, 450 arm on the right. I did a quick sand blast and repaint to it as some of the powdercoating has some rust.
500 DS up top and the 450 below.
500 swingarm 9.75 inches
450 swingarm 12.25, so exactly 2.5 inches longer
Honda 500 DS 6.25 long, 450 DS is 8.75, so about 2.5 inches longer here also...meaning drive clearances should stay the same.
