Well, I think............................... I know which I will go for. Just curious about your thoughts?

Currently have the 16" standard rear wheel.  Nitron shock fitted.

From what I have gathered lately, early 90's GSXR750/1100 rear wheels are scarce in England.  :pardon: Days spent searching the web for all the accomponing bits and pieces  :dash1:

A few clicks of a mouse and RPM fork valves can be headed your way.


Looks like an easy choice........RPM

Just jack up the gas cap on your FJ and put a modern bike under it. :good:

In the riding and braking department, a whole lot of fun.

True. But it is also fun modding the old bikes to improve their handling and braking.   :biggrin:  Dave

Yea Dave I know. That's why I own three of these damn things. Always something to play around with. Plus, the satisfaction of people's comments when they see one. "I used to own one of those", "What year is that, really?", and the like.

Mmmm, the valves plus the Racetech springs from Randy really transform the front end, really nice. The GSXR wheel is great as well, but you would probably get the most satisfaction from the front end upgrade first. Only problem with mine is the superb feeling forks now show up how shitty the rear standard shock is, LOL  :good2:

To my way of thinking, it's most important to keep whatever rubber you have in the best contact with the road.  I would (and have) put suspension well ahead of wider tires.  Straight-rate springs, fork valves and a proper rear shock will make your bike feel more "planted" on the road.  After that, think about your best path to fat tires.

In total agreement. I put an aftermarket shock on to replace the worn-out stocker, and straight-rate springs too. Those two mods combined with a flush and fill of good fork oil, and fresh rubber, made a world of difference in handling. Of course, it has on all of the other bikes that I've done it to.

I'm looking at the RPM fork valves too, but am waiting for the much-anticipated customer appreciation sale for them.  :rofl2:

Much as I thought, upgrade the front end then.

I did the GSXR rear wheel mod first due to cost, then later did the entire front.

FZR1000 wheel (17 x 3.5)
89 forks
Blue-Dot calipers
Galfer (like) rotors
HH pads
braided lines
RPM vales
straight rate springs (.85)
90 degree valve stem (easier to air up)

What a major difference that made, I felt like I got a new FJ that was planted in the front around corners regardless of surface condition. If you can afford to do the front, then do that first. I did not notice any improvements by changing the rear wheel. However, as mentioned by X-Ray, once the front is upgraded, the rear is really gonna feel like cold custard in an old sock. You have been warned. Let us know your impressions after you get the front upgraded. We really do like to hear about modifications to our FJs.
The glass is not half full, it was engineered with a 2X safety factor.

+1 on the suspension first. I have Randy's fork mod and shock. I was very happy with the handling at the Central Rally twisties in the Ozarks riding on 16" wheels. I am running Avon Azaro radials and am happy with their performance and longevity. Unfortunately I have just received another 16" rear tire and understand Avon is discontinuing the 16" Azaro. I might be forced to find 17" wheels. Dave
