    Full on modern front end swaps for dummies...help

    I was reading a post in the "custom" section where folks were swapping out the oem triples and forks for more modern USD and regular fork set ups...I mean, why settle for the air fork system after you ponied up for better rear shocks...right?
    So, what whole front ends can be easily swapped onto a GS frame that have better brakes, springs sans air support, compression and damping adjustments and even spring preload if need be?
    Obvious known hassles would be steering stop mods, axle swaps, and brake rotor size and spacing "if" one keeps the GS mags. Add handle bar mount options if clips ons aren't on your agenda and the donor front end doesn't have mounting for handle bars.
    Biggest concerns are neck lengths between my and the donor bikes suspension.
    I've been eyeballing a full on Honda CBR600f3, 600f4, and Suzi bandit GSF1200 assemblies all in the $225 to $280 range - straight but likely to require new seals and a go thru and better rate springs for the 600 forks due to the GS's weight.

    My 850G is getting all the good oem parts between both bikes, to be my oem mild relaxing cruiser bike{plus windstar fairing too}...a 52yr old mans easy bike.
    My 1000G is going to be the "play" bike {read 52yr old man who's not dead yet bike} - built in a way some folks here might not fully appreciate, but she's my canvas to paint.
    She'll have a shortened tail section {no frame cutting there}, Lic plate angled in place of the oem tail light, roughly 2" tall LED tail light above the plate, working the logistics on the intruder 1400 rear drive hub with new rim and adding a spoked front wheel with dual disks {yes, intending a spoke wheeled G model}, agm battery in the tail, rewire with M-unit and momentary push buttons on the bars and maybe a elongated 1/4 fairing....maybe.
    Aside from "why do it?"...anyone have any input from their swap experience or ideas?

    B12 is a good way to go.

      Im pretty sure the b12 is drop in and go minus the steering stops.. but thats still conventional cartridge setup.. butt theres a larg aftermarket for them. Meaning you can make them very track worthy, and you get the modern wheel and brakes. On the kat 600 front i did (41mm conventional) i did for a while run the factory gs mag but i switched to the kat wheel for 2 reasons. 1 i couldn't get the rake and trail down where i wanted with the 19 and 2 i didn have a set of gs calipers, and the katana caliper were way to wide to be retrofitted to the gs wheel. I believe the b12 runs the same diameter axle as the kat and gs, so if you're into making brackets and such it shouldn't be an issue. If you're looking for a USD option any direct swap for a b12 of kat 600 should be the same on our bikes too. I think the early 90s gsxr 1100 usd forks are about the correct length.

        The USD forks off the first gen GSXR1100 are the longest USD forks of the lot (except for dirt bikes). Bearings are the same so they slot straight in (steering stops aside).

        B12 forks are probably a touch longer (IE: better) but yes they are not USD.

        I'd go B12 because there's more of them and being newer they will (generally) be in better condition.
        Current:
        Z1300A5 Locomotive (swapped my Intruder for it), GS450 Cafe Project (might never finish it....), XT500 Commuter (I know - it's a Yamaha :eek:)

        Past:
        VL1500 Intruder (swapped for Z1300), ZX9R Streetfighter (lets face it - too fast....), 1984 GSX750EF, 1984 GSX1100EF (AKA GS1150)
        And a bunch of other crap Yamahas....

          I swapped in a set of 88-92 gsxr 1100 forks for my 1980 gs1100 restomod project. A drop in except for steering stops.
