Thanks for info jack. Just got to wait and see if bike is any good. The chap selling it is on holiday for 2 weeks. The only info I have on it is, it has been modified a bit, with different rear shocks and a 4 into 1of some some sort, flatside carbs, The person that told me about it thinks the model is a 1975 Z1000. I will have to wait and see. It has a MOT so can't be to bad. price is £1500.00 is that about right?

Hi, Good luck with the purchase, with regard to the 190 tyre check out the post what to do with new wheels wed 7th nov from me. Steve from Debbens posted this very useful info.


Hello KwackerZ1, I have rebuilt my Z1000 rear hub with a 6" rim and a 180x17 Shinko tyre, this rim needs to be offset to allow the chain to clear the tyre and then refit the wheel back into the centre line of the bike by fitting the hub over to one side. to do this you need to fit a wider swing arm and an offset motor sprocket, the 5/8 offset sprocket with a 530 chain gives enough clearance.
The widest rim you can fit without fitting an offset sprocket is 3.5" but this will not fit in the stock swing arm with the chain adjusters pulled forward.
Which ever wheels the first job is to ensure that the front and rear wheels line up, so many we see do not. Once you have the wheels aligned you can run a straight edge (long straight tube will do) off the face of the rear sprocket to see how much the front sprocket needs to be offset, sometimes it is possible to machine the rear sprocket carrier to move the chain line in.
The frame tubes will limit how far you can offset the chain line and therefore how wide you can go with the rear wheel, unless you run the chain on the outside of the frame tubes. The frame tubes are 240mm apart which gives a centre line for the wheel at 120mm, but as you need the width of the chain (non O ring 530 is 23mm) plus at least 1 mm each side for some clearance you need to allow a minimum of 25mm both sides of the tyre.
So with 120mm centreline for the rear wheel minus 25 mm you have a maximum 95mm centre of wheel to the edge of the tyre.
Regards, Steve

You can fit what you want if you've got the cash/skill/kit to do it...

Generally a 150/160 is max without going overboard on mods.....

I run a 180 with a JMC s/arm and an off-set front sprocket.... on me Z1000A2, and me ERL has a 160, aslo with an off set f/sprox

Stick with the STD 4.00 inch on the back.

It takes a real man to handle a bike with a wider tyre on the front than the back.
