As parts get discontinued by Honda nearly every month for GL1000 and Gl1100 I find myself looking for alternatives. I have a 83 Aspencade that sat for many years and has been a challenge. Po was notkind to it and not much of a mechanic. After carb rebuild and much agony finally have the engine running great. (Definitely recomend Randakks kits) aftermarket kits were junk needles jets and such. Now I am moving on to brakes. I am using a GL1200 front brake master cylinder and i t works great, actuallly prefer the solid one piece resevoir. I need a new Back rotor and have checked and honda discontimued but EBC has a listing for one aftermarket. According to their list it is the same as the GL1200 So does anybody know ifI can use the 1200 disk on my 83GL1100 Aspy?Seeing as how 1200 parts are a lot easier to find.

Yes, the rear rotor is the same.

EBC carries a semi-floating rear rotor for these that seems to work well . JB

Your 83 Aspy should have a ventilated disc which is thicker than the Standard/Interstate disc . I dont know if the 1200 series uses that same disc, It has a different part number listed.

Only the front rotors are vented on the GL1100 '82 and '83 Aspencade. The rear is solid on all models.

The GL1200 has several grooves in the rotor, which is supposed to help slough off water during braking. Other than that feature, the brake rotor is the same.

www.ebcbrakes.com They make brake rotors, pads, clutch discs, etc, for hundreds of types of bikes. And lots of car stuff too.

Thanks for all the answers! Got my hands on one today and they measure out exactly the same. Don't know about sloughing off water , but the grooves usually are a design improvement that is supposed to help even out pad wear and create less ridges on the rotor. I do know the 83 shares a number of parts with the 1200, same wheel bearings and such, great to know this is an alternative. Once again there is nothing like the Wing community and all the Forum memebers prove it.

Well then someonemachined the center out to fit the rear wheel and drilled thestud holes. Its been on my 83 over a year . It also takes an Aspy caliper braket to fit the vented rotor .

I have seen a vented rotor but It was an aftermarket part. Found a couple listings for them but when I called the companies they no longer were available. I do know that some 1100 parts are different for 83 depending on the part of year manufactured, but Can't find any listing for a honda vented rear rotor only fronts. That being said though I also have never seen a listing for wire spoke wheels either. But have seen one for real and the factory invoice , seems it was ordered that way and built by Honda.
