Later Wheels Upgrade - Swingarm Change Required?

Post by rkmason » Wed Feb 18, 2015 4:08 pm

Is the later model swingarm absolutely required to upgrade GL1100 wheels & tires from the early 19" / 17" to the later, wider 18" / 16" wheels and tires? Are any other later model GL1100 parts needed to get the earlier model speedo calibrated to operate correctly with the later model front wheel & tire?

Also, I'm getting confused about the different wheels used from '80 to '83. Did the Comstar riveted wheels come both in 19"/17" (1980 & 1981) and 18"/16" (1982) diameters? The 11 spoke one piece cast wheels were 1983 only, I think

in replacing the rear tire on my 83 g/w aspencade, I found that the OEM tire size of 140/90 rubs against the rear caliper bar that holds the caliper in place. I subsequently changed the tire to size 130/90 and it fits much better. not sure about the wheel sizes, IE: diameter and width, but I can look up the specs for them if needed.

I had to replace my electronic speedo gear on my 83 aspy, I used one from a earlier model and found it was a 3 mph difference in it. I had a state trooper clock me at exactly 35mph,(my bike's reading), an my actual speed according to the trooper's radar gun was my bike was doing 3mph less.(32mph), than what it was showing on my LCD speedometer. so I just go by what my readout shows and I know im going 3mph slower than the posted speed limit. its really ok, because it saves me from getting any speeding tickets :).
