80' GS450 Wheel compatible with 81' GS650E?

[Guest]

Recently bought a 81' GS650E that has a solid dent in the rear rim. The previous owner had bought a 80' GS450 rear rim as a replacement but never mounted it. Stock rim is 2.15x18. Size stated on the GS450 rim is 1.85x18. Besides the fact it's narrower than the front, would it mount correctly with my 81'? Am I better off finding a used rim of the correct size?

I'm no expert but that different sized rim and tire will alter handling, may not be safe.

That narrower rim will severly limit the size of the tire you can safely put on it. Keep looking for a proper-sized rim.

I'd imagine the twin 450 would have a narrower chain line than a 4 cyl bike so you'd probably also have issues lining up the sprockets.

That's assuming you meant you want to change the whole wheel, and not just the rim.

Thanks for the all input confirming my thoughts that the previous owner was an idiot for buying that wheel. Bought a replacement off an identical bike for cheap.
