Thanks fj 1289.  I always get them mixed up. I will need to know what the off set is if you can Jeff
Thanks again
Dan

Will not a chance to measure till later this week but this might help:

This came from here.  There are actually a lot ox Zx14 front end/wheel conversions out there.

Oh and this is in the text:
"The result is this. I over layed the ZRX triple over the ZX14 hole centers. You can see in this picture that the offsets are identical. The 14 is 215mm and the ZRX is 205mm."  Not sure if it makes sense or not; identical but different?

been chattin' with GK and jt looks like this is a great swap but would be well North of a thousand bucks.

Just figured with fork brace, valving,springs, and brakes. Just to get the fj forks up to par. You've got atleast $600 into old technology.. Way more if you don't have the tools/knowledge. And have someone else do it for you.

Then you have a lot less weight both unspung an reciprocating. And they look so good

This is where the RPM fork valve comes into play. It is designed using today's technology to convert the forks from old school damper rod/controlled orifice "valving" to the same shim stack technology used in all USD forks. Plus, it goes one step farther with the patented bypass technology for superior performance in all conditions.

As far as less weight, I am going to have to question that one...

The stock FJ for design has much less "unsprung" weight that any USD fork as the portion of the fork that is unsprung is the aluminum slider & internal damper rod.

USD forks have the steel fork tube as well as the lower mounting hub for the wheel & brakes that weigh more that the FJ parts.

So, if you update the front wheel to a newer wider wheel it will be lighter than the O.E. wheel and you can add the RPM fork valves and you don't have to do any "modding" to install.

So, best bang for the buck is the RPM fork valve system for the stock FJ forks at a cost of less than $365.00.

I think the "and they look good" is a matter of personal opinion.

As always, beauty is in the eye of the beholder and everyone is entitled to like what they like.

Personally, the more USD conversions I see on the FJ's, the more I'm finding they don't quite look "right".

At least, not to my eye....

USD forks were developed because they are more "rigid" than conventional forks.

This is another one of those "not really noticeable" in street riding. You are getting up to track speeds when they make a difference where even the tiniest things matter.

But if they look cool to you, go get 'em!

Question: is it $365 for just the valves or does that include the springs your web site says the new valve stacks need?

The is the combined price for the fork valves, required springs and oil.

1. the rpm route leaves you with stock brakes and flex-forks - if the stock forks are stiff enough why do you sell a brace?
2. a vendor's opinion that his technology is superior is rather weak evidence. are RPM equipped FJ's cutting quicker lap times than USD equipped bikes? Show me EVIDENCE not self-serving opinion.

3. the claim that these are a drop-in item that works for everybody is highly dubious

bottom line: the RPM stack is a patch on old technology that leaves you shopping for other upgrades.

It has a market but is not the high-end market.

That's a pretty gall darned good deal then!

Definitely the case...  Wizard draws small crowds of people who've figured out something's not right.  Even my boss who's never ridden paused to tell me even he noticed something's not right with that bike...



I like it.

Well, Mr Burns, I guess it is time for you to put your money where your mouth is.

The Renegade Rally is coming up next month, this is my personal invitation to come on down and and see if you can keep up with this "vendor" and form your own opinion. That way you can speak on a more informed basis instead of your "opinion".

If you have any doubt of my "opinion", you might just do a little forum searching of the praises of the fork valves for other opinions from happy customers. I can find you plenty of you can't find them.

So, don't knock it until you see it work for yourself and hopefully we'll see you next month.

Regarding the fork brace, no matter what fork design you have, there is flex. So, the fork brace is offered because that helps eliminate flex and also to keep the old plastic fenders from breaking the tabs off.

If you think USD forks don't flex, then you probably ought to do some research because that is why the fork tube has to have a larger diameter and larger/tubular axles are required to combat the flex of the fork tube. But since the lower portion of the shocks are the sliders you cannot use a fork brace. and must rely on heavier components to combat the flex.

Kinda looks like Dan's. A little. Or is it the other way around? 

[FJmonkey]

Are we doing competitive racing now on the FJ? Anyone racing an FJ? I doubt an FJ with USD fork is anything close to current OEM USD equiped bikes. What is your point?

Some of the cost advantage is not needing to swap out a complete front end. I installed my RPM suspension in my drive way. The service interval is also longer than USD forks. So I spend less time on maintenance.

If you don't trust the sellers claims then ask the forum how many use the RPM valves and what they think of them... I think Randy has a lot of really happy customers. I am one of them, so count me as biased. Almost 20K miles in the RPM front, mostly in the twisties....

[FJ1100mjk]

Anyone racing an FJ?

Yep...

1. your doo-hickey may well be an improvement but you still need wheels and brakes -it is just a start
2.  are you saying the FJ fork is as stiff as a USD's?
3. I'm sure you are far better rider (hell I'm almost 70!) but a personal contest would prove nothing about the components
4. testimonials are notoriously untrustworthy

as I said your product has a market, it is not the whole enchillada but some can only afford a taco.
