Which caliper

[Bones]

Went to the Haigslea swap meet today and managed to score a GSXR rear wheel. It's only a 4.5 inch one but was too good a deal at $100.00 to pass up





Question is, I'm assuming it's off a late 80's model going by the size and the white paint, but will all model brake calipers fit or do I have to look for one for that particular model.

Also what size tyre would be suitable for a 4.5inch rim, 170 or 160.

                                                                    Thanks,
                                                                      Tony.

Tony,

Yes, its from an 89 GSXR1100.  The 750 uses a 5 bolt pattern on the sprocket.
I've got the 750 wheel, and have used both 160/60x17 and 170/60x17 tires on it.
Really doesn't make a lot of difference, but the 160 is probably the (more) correct size.
The caliper is a Tokiko underslung twin piston unit with an alloy brake stay.  I believe this was used on a bunch of Suzukis of that era.
I wouldn't worry too much about the caliper as long as it fits the disk, its only a rear wheel after all.  However finding the caliper hanger may be a chore.  Let me know if you need some measurements.
One thing you'll want to do quickly is get that wheel powder coated or painted some color other than white.  White wheels are a bitch to keep clean.

here's a picture from an 86  750 slabbie if it helps at all, stock standard i believe, pretty sure the owner wont part it out though. you could always ask though.

I've got one complete with pads and hanger winging its way to me as we speak Ken. Being an 86, it's got a different styled wheel, so probably different widths on the hangers, spacers, etc.

I bought one off an 89 model which is what the wheel came from, that way I know I've got the right one.

Is that a picture of your slabby, I know you bought one recently, but I thought it was a later model.

If you haven't already checked, do yourself a favor & verify that the wheel is round & true. You will need to mount the wheel in a swing-arm, or fabricate a couple of uprights tall enough to support the wheel & allow you to spin it. Then take a piece of coat-hanger wire or bailing wire & tape or clamp one end of the wire to your wheel support. Then bend the wire to a pointer that barely makes contact with the edge of the wheel. Spin wheel & watch for gaps between your pointer & the surface of the wheel.

I bought a set of wheels for another bike project, cleaned them up, then had them blasted & powder coated. When it was time to mount the tire & balance the wheel, we found that it was slightly out of round.

Good luck.

Just in case anyone winds up with a less than perfectly straight or round wheel from an eBay vendor (and trust me when I say you probably will), I can without hesitation recommend mc wheel.com for straightening and repair. My FZR front wheel showed up with a pothole dent on one bead that was not observable in any of the eBay pictures but was easy enough to see once I had it in my hands. The whole transaction with MC Wheel was flawless. Turn time was less than a week, runout was less than .003 on the whole wheel and the wheel was cosmetically ready to install as soon as I received it. I have no vested interest in this business, just a satisfied customer.
