Swingarm's and Tire fitment

[ThAzKat]

Waltari:
RF900 swingarm with some spacer mods
180 tire with Busa wheel

note: you can use a gsxr wheel, RF900 wheel or busa wheel

Sinfulkat:
Bandit 400 wheel will fit stock swingarm
88-89 gsxr wheel will work 4.5"

Note from Thazkat and sinfulkat: you need atleast a 4" wheel for a 160/60 tire, the stock 3.5" pre98 wheel causes a mushroom look and the edge falls off to fast and there is no way for you to get rid of the 1.5" chicken strip unless you like sliding sideways.

for the swingarm swap:
Busa
RF900
Gixer
swingarms will work with a bit of modification to the frame for clearance and homemade spacer's. You can go to this link for more info on the swingarm swap

Actually, I'm running a RF900 rear rim. No idea if a busa rim will fit or not. I know a bandit 1200 rim is a straight swap for the RF900 rear rim.

[Waltari]

The RF900 and Bandit 1200 arms are basically the same arm though there is a couple different style of brake arms and calipers mounts. Just make sure to get a caliper mount and arm that matches the swingarm you're using.

The lower subframe rails must be cut and welded higher up as the wider swingarm will make contact with the lower subframe rail on the clutch lever (left) side of the bike.

Since the footpegs/brackets are on the lower rail they will either be at a higher more aggresive riding position or you must weld lugs into the frame downtubes and use some kind of bolt on rearset of anotehr donor bike.

I made the spacers show below so I could keep the stock needle bearings in the RF900 arm but also use the stock katana pivot bolt (to avoid having to drill out the frame for a larger bolt).

The RF900 arm is slight more narrrow tha n the kat arm so you must also make a small spacer for each side (sorry don't have the thickness measurements in front of me).

After that, you can use your stock shock or better yet a unit from and RF900 that matches your arm. You'll need to fabriated dog bones with a slight offset at the top because of a slightly steeper angle on the upper shock mount.










Oh...the busa part of my rear end comes in the form of a later model busa rear caliper/master.

Yes, thank you Waltari for the input. I was hoping for those pics. I have been told by other's that the Busa rear wheel is the same as Gixer and RF 900.

RF900 Complete Rear

Ok guys I have stumbled onto pretty much everything from the back of an RF900 there are a few questions i had before i went ahead with the final purchase. All the parts are currently on ebay and hopefully will get for a really good price. Anyway the questions are. Will the stock rf900 dogbones be correct? Will the 900 shock be suitable for 2 up riding as well as 1? Will the master cylinder on my kat work on the rf swing with the correct bracket or is the rear brakes on the rf900 just as good? Is the swingarm lighter or heavier being its aluminum? What Chain guard will fit? What other problems did anyone run into on this? Chain and sprocket length and such. Thanks ~Heath

Ok guys just got my RF swingarm in, in the mail, i recieved brake master with the bar on it, swingarm, dogbones and the weird lookin piece shaped like a plus sign i guess you would say. The shock and reservoir all in one piece of course. How would I go about getting the shock tested before I put it on? Or should I just stick it on and make sure its ok. I am debating whether or not to do the swingarm as I spoke with waltari and I think it may be the narrower one. it has a U shaped channel on it where the brake bar mounts however the brake bar goes around the outside of it not on the inside. So I may sell this swing arm and look for the wider one since I want to put a 180 Tire on my bike anyway and that was the purpose for me getting this swingarm. Ohh and the wider rim, since with the narrower swing i can only use a 4.5 inch rim i don't know if a 180 will fit on that. Thanks ~Heath

[Waltari]

Heath...post of a photo of the arm (clear shot of the inside on the brake caliper side) and I can tell you which it is.
