Does anyone have experience of fitting a larger width rear rim and tyre to a Z1000 or Z1. I would like to fit a larger tyre but not if it makes the handling worse!
Also has anyone rebuilt the rear hub on a Z1000? Is there an easy way of getting the chrome ring (that holds the spokes on the brake disc side) off? Any advice would be appreciated

Z1000 help needed!

This ain't an easy or cheap route... you can see my Z1000 in the gallery, lastest entry's, the black one with GSXR gold USD forks & JMC!
I believe a GPX/ELR or similar set up fits! Then your sprockets will be out of line, so an off-set front is needed! Handling can't get much worse than standard anyway!?
My bikes got 180/55x17 rear & 120/70x17 front, braced frame & Ohlins, but still does a nice gentle weave at 60mph+ on even sweeping bends! But wouldn't have it any other way, would we!

You may be able to go up as far as a 150 or 160 rear with just an offset sprocket and no real clearance problems but it helps if you come down to a 530 chain. (Simon Gilling Newzletter #48 explains how) And you'll need a matching front - 120.
Pigford re your weave how much bracing has your frame got?

It measures as 1.25 narrower and on a 160 that can make the difference between touching and not touching the tyre and gives the same extra clearance for the offset sprocket atthe top end. A modern 530 is more than capable of coping with the weedy power output of a Zed compared with a Hayabusa for example which runs a 530, it's lighter by about three and a half pounds, and you can't get a 630 in an "x" ring if you want one.
DID 630V 0 ring Professional series pin length = 25.30mm
DID 50(530)VM Premium Xring pin length = 24.90mm.
Figures from DID Technical pages making a differance in total width of 0.4mm and against the tyre of 0.2mm - the sprocket to chain clearance is bigger than that.
If you need to save 0.625mm (by your figures)you would be better trying different manufacturers tyres as they all vary on the fitted width, run a non 0 ring chain with a chain oiler or take a razor blade to the edge or the tyre.
If you want to go for an offset sprocket a gpz750 front sprocket it will give you a 6mm offset and costs about ?11.
Unfortunately you can't get an offset sprocket for a 530 / Z1 combination without resorting to paying ?60 plus vat.
I could loose 28lbs if I stopped drinking beer and went on a diet!!

DID H/D O-Ring Chain 630Vx106 ?82.99
DID Gold H/D X-Ring Chain 530ZVMx120 ?70.00
PREMIUM X-RING GOLD: D.I.D's Professional sealed chains incorporate D.I.D's uniquely designed seal-rings which seal D.I.D's special "V" grease in the pin/bushing area and lock dirt out. They are expected to last at least ten times longer than ordinary construction standard chains without significant wear elongation under satisfactory maintenance.
You can run whatever chain you want but ten 630s would be over ?800 quid - you could always put the ?60 plus vat you saved on the exotic sprocket towards it though. A cheap VN800 513.17 sprocket will do if you don't need the offset with a 482.38 rear from B&C to keep standard gearing with the standard wheel
I measured the 630 off my A1 and it's 26.4 I don't know what make it is. There's a 160 tyre on my other Zed with a 530 and there's stacks of room I could probably fit a 630 back on there if I wanted...
If you really want to save money on chains fit a Scotoiler -you will get three times + the service life from a chain.
I hope you notice they say "expected" and "ordinary construction standard chains" - you have to watch these marketing types!
The wear resistance figures are x ring - 3630, o ring -2050, "ordinary construction standard chains" (now where have I heard that before) - 410.
Meaning that before you decide to go for the 50 and your "O"ring isn't knackered maybe you should consider what savings you are actually going to make and evaluate what you are needing in the way of clearance. If you are fitting a 50 to gain 1mm clearance why don't you just have a longer sleeve made for the shaft seal or put a washer in there.
Just to show that I did look this up because I was going to do it to the Harris - JTF 580 will also give another mm of clearance for the 50, with the 630 I get 5mm clearance with a GPZ front, 160/60 bridgestone on a suzuki 4.5" rear with the rear aligned to the front and cush drive then aligned to the gearbox. I presume the original engine / wheel alignment is the same as Z1000A3 as that's the running gear that was on when original.

On one of my bikes with a twin shock set-up there's enough clearance to the tyre but the chain's a gnat's dick from the spring with a 530 - I'm sure that there isn't even 2mm to spare on that side. I suppose it depends on your swingarm and it obviously wouldn't be a problem on a monoshock. Machining down the offset sprocket would take it the other way but there's not a surplus to give away chain to tyre either and repositioning the shocks seems like too much trouble. As far as I'm concerned the thinner the chain the better.

If you struggle for room that much why not put a 150 on?
I'm not struggling for room. When I got the bike there was a 170 on it and it was rubbing the 530 chain that was already there.. I put a 160 on it and it clears happily. If had a 630 the chain would hit the shock it wouldn't matter what fucking tyre was on it unless I start macining the offset sprocket and the cush drive to move the whole thing over towards the new 150 tyre. What's the big deal with a 630 anyway Rich there isn't one on there and I'm not putting one on. What part of that pisses you off so much. I don't need a 630. I have enough room. Thankyou.
