GL650 has the same cast Comstar wheel and the same diameter forks. They're probably a little longer than your CX650C forks.

I thought the cx650c had larger diameter forks (39mm) and they looked longer too?

GL650 37 - CX650 39. Although the forks on the CX are longer and leading edge, the distance from axle to bottom of the triple tree is about 1" longer and the neck is about 1/2" longer. Others have done it, but I cannot tell how much work it will be to change over. Let us know if you try how it works out if you try it.

I probably leave it alone. I got the bike its all original. Been in storage since 1984, in garage. It had the tires from 1983, 2800miles. I changed fluids, it started rt up. I put new tires plugs & needs fork seals. It has all paper work 1 owner. My friends brother bought it new & he past away & they GAVE it to me. I think he gave a little over $2400.00 for it new. I have the receipt. I get pictures on here if I figure out how

The icon below between the chain and the camera to post those pictures.
Or just click the place in the box where you type your message where you want the pic to be and drag & drop the pic into the box.

Double-H pads + stainless steel hoses + adjustable brake lever did the job for me.
Not as strong as two disks, but strong enough to lock the front with a healthy squeeze.

1983-up VT750 Shadow and VF700/VF750 Magna fork lowers should work on your 39mm tubes. If you get the 1983 model year Magna parts, the rim will even perfectly match.

Edit: The 1983 VF750 Magna may have or may not have 37mm fork tubes, but the 84-up 700 has 39mm for sure. Two different sources have two different numbers for the 83, but they all agree on the 84-up. Also the rims are interchangeable between different sized magnas and shadows of that era, so you can still snag an 83 wheel. All those similar looking wheels have the same rotor spacing and axle diameter, and swap from bike to bike.

Ah yes, the Magna wheels are 18", that's true. For a street bike, no biggie, but if you want off-road tires it kinda is. So use the Shadow rim, as it's 19". The spoke pattern is different though.
