FZR1000 Forks

[racerrad8]

Just another reason damper rod forks do not have to suck...

Evolution and revolution at RPM

The RPM Fork Valves have converted the FJ damper rod fork to cartridge style forks. They now have a shim stack valve for both compression & rebound and no longer use fixed orifice to control movement.

Then add the patented bypass technology and you have the best bang for the buck...

Here is some more reading on the RPM fork valve as well;

Don't worry about improving 25 year old fork technology, manufacturers aren't. That's why they went to cartridge forks. I did the yzf600 fork swap like John Cain says . Best thing I've done to the bike. No machining what so ever. Transformed the handle in one afternoon. Yes it took a little bit to collect all the parts. Again, thanks to John Cain for the help in the swap.

Hey Mr Mumbai, I'd go with Randy's valves and matched springs plus a fork brace for good measure, then the front end is worthy of the 21st century. When considering all Fj mods to my 86, the front end tweaks are certainly near, if not at the top of the list. Over the 8 years of ownership I've done various things to my ride, some made minor improvements, others were game changers. My front end is by far the best it's ever been and it's really difficult to think of how it could behave any better. I've never ridden really modern sports bikes, but I'm looking forward to kicking their arses sideways.
Yeehaaaa

Well, I went looking for an improvement and found it.

Maybe we should do your 89 with the RPM fork valves and you can give a true comparison.

You will have both options and can give your feedback of performance Vs. Cost Vs. Ease of installation.

I hope you will try it before you knock it.

Let me know if that is an option for you.

I have added RPMs emulators to my 1989 FJ, my brother has a ZX12R who compares my FJ to a tank, anyway he took my FJ for a ride after these were fitted. He didn't know these were fitted until after the ride at some decent speeds. His first comment was that the front end feels as good as his bike (shame about the rear). Unless you tried these emulators (I have race-tech emulators on my Z1R, not bad but not as good as these RPM emulators/ race-tech springs) I suggest your (the knockers) opinion is invalid.

I havnt even tried the rpm valves,  and yet I know they will improve the forks 110%
