    Default 78 GS1000 suspension upgrades

    Looking to do some updates. Thinking about swapping 1100e forks, swingarm and upgraded brakes. I would like to stick with vintage 18 inch wheel. Maybe a set of dynamag wheels. I want the bike to have the vintage look but have modern performance. Looking for some suggestions?

    Well, 1100 E forks and brakes won't give you modern performance, they're over 35 years old.
    What 18" front wheel? It's a 19" wheel
    Old mag wheels need to be X-rayed (?) for cracks, they tend to fail with age.

    I went with 90's Katana forks and brakes, front and rear wheel along with the 1100 aluminum swingarm. Still 25 years old, but much closer to modern

    I guess I forgot to mention the internals for the forks would be Racetech. Had a buddy do the same swap and it looks killer.

    You’re talking about the spec I have (with original wheels). I did get an 1150 wheel 3.5” to put on but never got around to it.

    the 1100 fork with the racetech kit inside gives you full adjustability. Stock preload and rebound and then compression on the emulator.

    my shocks are works performance trackers, swingarm is also 1100

    Honestly, this makes no sense to me. Those pieces are barely any better than what you have.
    Far better in my opinion to upgrade the existing components. Springs and emulators in the forks, stainless steel lines and good pads for brakes, good shocks in back. Just swapping the 1100E parts in there won’t do much.

    Yep, all the 1100E parts give you is adjustability. I primarily went that route as a set came up at the right price with brands new stantions...

    It sound really weird to put lot of money on Dymag and put stock 1100 fork and brakes.
    I think only the swingarm will be an upgrade.
    I rode my GS1000 in various from with 17'', 18'' wheels USD, RWU forks Mudholland, Marzocchi shocks.Right now i'm rebuilding it with 18'' gsxr 1100 wheels, cbr600f3 41mm forks, GS1100 swingarm, YSS rg362 shocks, AP calipers, ISR rotors, on a braced frame with the headstock moved back and with 2 degree less of rake.I have more than 3500$ invested in the rolling chassis and I still have work to do.One thing I would really like is a set of adjustable triple clamps, maybe next year...
    I'm building it with vintage racing in mind.This is why i'm using 41mm fork.
    I have trouble finding really good 18'' tires now, they only seem to be available in Europe.

    I really liked how the GS rode with a Bandit 1200 front end with matching rear wheel in a 1100e swingarm using YSS shocks.

    I'm just going off what a buddy did and he was very happy. The bike is a street bike but I would love to be able to do a few track days a year with it. So I am definitely open to suggestions. Where did you find your AP calipers?

    I hear you. I swapped out my 83 forks for some 89 forks. Went from "kid sister" skinny, no adjustment OEM forks, to fully adjustable 43mm RSU forks and kept my 18" wheels. Parts were easy, others more complicated.

    I wanted to keep my wheels as they were already aftermarket & kinda "period correct" for the bike without looking like everybody else's bike with modern (17" wheels & USD forks)"legs" on their vintage bike. It took new spacers and fab'ing brackets by hand, but it was worth every drop of sweat.

    The 1100e swingarm would also make a fine upgrade to your 1000. I am just in the process of putting one on my Mrs' GPz1100. The OEM swingarm worked great on my Suzuki, even with a 160 tire, but I wanted "just a little more" on mine. Metmachex was my answer. They are still in business, if you're interested.


    Enough of my blithering... the end results are below...
