ZR7-S Shock with an 1100 17" rim

How to make an old bike handle like a new (factory) one!

ZR7-S Shock with an 1100 17" rim

Postby JezZedexE1 » Sat Oct 13, 2018 6:55 am

Has anybody done this or is it a viable swap? I did a search but not much came up.

With the shock being 7mm longer and the wheel a 17" it would mean slightly lower back-end. :popcorn

I am sure one of you will find or know of a good reason to try and another to say don't bother. :)

It is not something I have looked into. It was just a thought, as I have a couple of the ZR-7 shocks and the bike which has one fitted has a lean angle that is horribly wrong. :thumbup

I was tinkering with all that when dreaming of doing the (now defunct) Maxton Mile because they req'd a proper high speed radial tire.
I remember the axle/eccentrics being different sizes but I barely remember where i was yesterday so it's all a blur

What's the issue with your zr7s setup or what don't you like about it?

With the back a bit higher due to the shock being a bit longer, it leans over a bit more than with a standard set-up. Don't want to lug a bit of 4x2 about all the time.

The 1100 axle is 20mm, so either source a pair of used holders or drill out the stock 17mm to 20mm. They are the same size apart from the hole. See here for a bit of info.

Standard wheel sizes on mine with ZR7 Shock. With the concentics on the back in the right position (axle up) I didn't notice any difference. With a smaller diam back wheel the bike would sit a bit more upright so that part should equal itself out with the shock.

I guess I need to check the adjustment of the shock. It may be adjustable. Have not actually checked. :oops:

I have a horrible feeling the block thing which the side stand connects to may be to blame. Anyone else have problems with it failing? I cannot see any other reason why the lean angle is so much. :( :roll:

When I get the assembly process started on the current one I am doing, I will put a ZR7-S on to see how that works out. :popcorn

Was thinking that but didnt want to say it. Are the sidestands on both bikes the same?

Yes, I have checked and measured, to make sure it is not an NA stand. :(
