Question on brake calipers

[fouchie1]

Hi all
I run a standard 1979 gs1000s with solid brake discs (sorry, rotors as you guys over the pond call them) and have braided hoses fitted and am thinking of upgrading the fronts, i have been offered a set of GSX1100 vented discs and a set of Gsx750 calipers from a 1980 bike and am told that these will directly replace the originals. on a GS1000
Question is, are these direct replacements, and has anybody tried or know what can be fitted as replacment
regards
Les

Has nobody tried later discs or calipers on there GS1000......?

I posed a similar question a few weeks ago, and received a similar response. I've since gotten a set of VF500 two-piston calipers that look like they can be adapted without too much fabrication. I haven't heard of a newr caliper that just "bolts" up.

Uncharted territory?

Hi Mr. fouchie1,

A lack of response could mean that no one has tried your particular combination of upgrades. That means you could be the first to gain this experience and share it with the GS collective. Be sure to post your results as I'm sure many will appreciate your efforts. I'm not quite brave enough yet to go sailing off in such uncharted waters. 8-[

Thank you for your indulgence,

I bought and sold some front rotors off a 79 850 if I remember right. I compared the bolt pattern to the rotors off my GS1100. They seemed that they would of bolted right up. I bought these rotors to replace the ones I had but when they arrived they were the older solid type so I didn't use them. The Ebay seller said they were off an 80 and they weren't.
I believe the only difference in the rotors is that the older ones were thicker and weighed more.
To answer your question they should bolt right up.
