Let the fun begin...RPM Rear Shock

[racerrad8]

Well, I have, in my hands the first RPM rear shock to start testing.



Fitment will be started today and then testing should start this weekend. This is the early model shock and the late model is supposed to be be shipped by the end of the week. If so, that one will be fitted by next weekend and the testing will begin on that one as well.

There will be several thousand miles put on the shocks with changes to valving completed, spring rates tested and settings fine tuned.

Since we still have a couple of months of good weather before winter really hits, we should not have much trouble getting the testing completed, the changes made and the production started.

It has been a long time waiting and I believe the results will be worth the wait.

Awesome Randy, thanks for the update. Wish I lived close enough to be one of your test subjects. You could then state that your shock was monkey tested and Power Ranger approved.

Looks like a damn fine christmas present suggestion!
Whos with me ?

Where is the remote gas charge thingy?  (Jargon)

I anticipated it to have a gas charged can hanging off, no?  [asks the guy without an FJ]

Not required and should not be required unless drastic changes must be made to the shock body. The shock body is large enough to get all of the required oil volume and valving requires completed in the unit and not have to rely on the remote type reservoir.

The reservoir is only required for universal shocks that are not specifically designed your the FJ and additional valving must be added due to the weight of the bike.

I had a shock that is designed and going to be specifically manufactured to fit the FJ. It is not a universal application that will be able to change the ends and it will fit any other bike like the other shock options on the market.

Just started to twitch a little in excitement and started looking for a buy now button. Gonna have to get that item for my 86 and get the buy impulse looked at by trained professionals.

I don't see any ride height or compression/rebound damping adjustments?  :-(

There is a coil over adjuster on it

The sag will be controlled by the coil over adjustment at the spring, what else are you looking for regarding "ride height" adjustment?

Plus every shock will have the bearing at the coil over adjustment nut for ease of adjustment. (it is there too if you look closely)

No, there are no compression or rebound adjustments. We have moved past the 80's technology and they are no longer required with the valving of the RPM shock and/or the RPM fork valves. This shock is going to be going through several thousand miles of testing, multiple different riders & bikes, single and dual riders, with & without luggage and will be set to be the best overall combination for performance and comfort.

Just like the RPM fork valves it can be tuned on an individual basis, but the RPM shock you get right off the shelf is going to be a wildly significant improvement over the stock shock as well as any other shock currently. Based on the dyno testing the RPM shock is superior to the other shocks on the market with the benefit of the inertia bypass valve for better comfort. The reason no one else has this valving is that is is patented in multiple design versions and no other shock manufacture, Penske, Ohlin or anyone else for that matter has anything comparable.

This shock, just like the RPM fork valves, has taken the next step past the dated technology you get when you buy any other universal suspension product that had been adapted to fit the FJ. That is why they have to include the adjustments so that you can make it work for the FJ.

RPM suspension products are designed, tested and tuned specifically for the FJ; not a universal product adapted to fit and work on the FJ.

Didn't we have the same discussion when I introduced the RPM fork valves

Since the 84 to 87 years don't have dog bones, the shock length is used to raise and lower the rear wheel. Will the RPM shock have the function to raise and or lower the rear wheel?

Hummana Hummana Hummana! Sorry momentarily lost the power of speech.  Andy u sexy beast, an eibach coil!  I have had these on numerous high performance vehicles and they rock!  Loads of eibach gear about in europe and the uk!  Very well respected.  Is there more eibach wizardry or just the spring.

I love the fit and forget ethos!  I can't be doing with all the fafing about!  Infinite adjustment is a Stayed tech from the early nineties, look at all the new springs on the open access rear ends of new Hondas, suzukis and yams, no reservoirs (I will admit many seem to be gas of some description as they have a yellow explosion warning triangle on them but just as many are oil based)

Did panic for  :biggrin:a moment when i saw the pic that it was not for the late model, but I was comforted as I read on!

Don't suppose the spring comes in blue?

So who does own/control the patent? I guess you or your
Manufacturer?

Is the manufacturer eibach? Oh dear god let it be eibach!!!!

Any ball park on price for early and late models?

The manufacture does, if I owned it I would be making shocks not selling FJ parts...

Fortunately they are willing to work with me to bring the FJ suspension components to FJ enthusiast.

It is really hard to get companies to work with me manufacturing items for a bike that was last sold on the U.S. Yamaha sales floor in 1993, almost 20 years ago.

Its like an addiction: we´re still considering and saving to buy the fork valves and there is another gadget on the way...

MMMMmmmmmmm  Randy, do you know that there is an economic crisis and that you could be the guilty of lots of divorces?
