Brake Caliper Swap?

[madmikeracing]

Has any one swapped Hayabusa Calipers on to GS 1100 or GS 1150? Just wondering. I have a gixxer 750 front end USD type but they are like shorter and i was gonna machine up extensions for them. maybe Busa front end
swap? anyone done that yet?

They are too fat for the 1100 with standard wheels/forks. You stand a good chance with the 1150 as the originals are opposed piston and as such the forks are wider and there is a lot more room to play with...

Thanx for the Reply. I picked up a pile of bandit stuff may sway some of it.

So if you swapped a GSXR 750 front end on, why are you asking if Hayabusa calipers fit a GS 1100 or 1150? Shouldn't you be asking if they fit the GSXR 750?

any of the opposed piston calipers are going to have trouble on the vintage wheels unless you have very wide forks (triple clamp spacing), and have brake rotors spaced out further. Or if you angle mill the inside surfaces of the calipers, but careful attention needs to be paid to the thickness of the casting in relation to the piston bores inside.

if you have not yet swapped the USD and very short height GSXR 750 front end, you might want to consider swapping on a more appropriate front end, as the spacers we're not going to be the best thing for the forecast specially considering you will be attaching to aluminum upper stanchion tubes. Without some seriously long extensions, the GSXR 750 front end will make the bike handle really great for mellow riding on flat ground without any sharp curves or speed bumps or potholes, but will disable you from ever being able to lean the bike far over into curves and enjoy them, because you will now be grinding your exhaust and your stator cover at any moderate lean angles when really getting into it in corners.
Air cooled Bandit GSF1200 forks are the ones you want, 775mm tall. With any triples that would mount them to your bike, you will be within 19 mm or so of your stock ride height not considering tire outside diameter. The fork tubes themselves are the same length as a GS 1000 or 1100 E, not the longer 800mm katana, but the GS triples are offset down a little bit to give it extra ride height.

You can lose a little bit in the front, but you will need to compensate a fair bit more in the rear with shock length to keep your corner and clearance.

Also, VT1000F (VTR1000F?) Superhawk/Firestorm forks are 41mm cartridge forks & 775mm.
Both are fantastic upgrades. The earlier version Bandit 1200 forks with the one piece fork brace mounting lugs are a bit more sporty valving than the later versions with a more conventional fender mount.

Check into V-Strom DL1000 triples for mounting the Bandit 43mm forks. Have them measure the steering stem I'd, you should be looking at 7 or 7.25" between the two bearing surfaces, bottom to top, outside of the bearings. The 43mm fork DL1000 steering stem looks the same as a GSXR/Hayabusa aluminum stem, but it could be a taller version. 42mm offset is nearly perfect for a bigger 17" tire or more stable steering on a shorter 18" front tire.
V Max 1200 1993+ triples give you 50mm offset for 18-19" wheels on our bikes, but lower bearings need spaced up 12mm to make the steering stem length work without swapping stems. 50mm is the same amount of offset as most stock GS triple clamps.

Chuck thanx for the Info. I have a collection of stuff and also Bandit wheel and swingarm but the front end is what needs it . Primarily the Brakes seem so crappy compared to a brembo equipped Bike (Ducati i have owned 2 ) I was under the Impression Busa calipers would be a good swap along with suitable Rotors . Thank You For the Information. I may start looking for TL 1000 parts. And also some Bandit Forks . Appreciate your Time and Information, Thankyou
