Front Rotor Compatibility List - GS450GA "Suzukimatic"

[Alf]

While in the epic pursuit to find parts for my illustrious 82 Suzukimatic, I couldn't find any good info on what front rotors would fit or interchange with my bike since it's looking like it wants to run at 45 RPM. Below is what I found on OEMCycle.com for what models will interchange, and it is a lot longer than I could've expected. Don't know who this will help, but I hope to keep cataloging parts that will swap between models to keep some 450GA's running a little while longer.

Thanks for the compatibility list. A few years ago I needed to replace one or both front rotors on my GS650G due to warping. Got a pair on eBay from a GS850 well in spec and all was good.

I have never gotten around to actually measuring the rotors, but it seems that all single front rotors are about the same. All dual-disk rotors are the same, but different than the singles. Not sure about the rear rotors, but I think there are differences in the L models.
