HYPERPRO SHOCKS

[Neil]

Has any one had experience with HYPERPRO shocks I have just bought a R1200R from interstate and it was supposed to have WP shocks but they are HYPERPRO and I think they are the cheaper ones the bike seams a little low by about 10 to 15mm there is no remote pre load on rear and no external gas reservoir thy have a wheel on the bottom I assume is rebound adjustment and a very small dial (for sake of better description )that may be a compassion adjustment when the bike is standing upright there is only about 30mm of front and rear shock travel be for it would hit the bump stop rubber

Neil,

I replaced my cheap originals with the Hyperpros and I could immediately feel the difference. Before the bike was very harsh over bumps, it felt best when riding with my wife. The hyperpros have changed all that and with a quick adjustment from myself to riding two up, it’s a snap. You can download the Hyperporo manual on line, and that will help you learn about this shock. Also a wealth of information and one that helped me tweak mine is Don at Dilegburger on this or something like that, he is on this forum and has many valuable write up about shocks. Do a search and it will come up. Goof luck and enjoy the bike!

Neil..

Please consider using the occasional "," or "." and a paragraph break here and there.. it's a bit difficult to read what you're asking about.

From what I can gather - it does sound as if you have the less expensive Hyperpro's on the bike, probably without compression adjustment (the bottom one is rebound adjustment - just like the stock shock.)

There are several things that may make these less then optimal for you. Weight is a big one. If the spring was setup for someone who weighed more or less then you, or normally carried a lot of touring equipment, it may not be the right spring for you. Luckily - the springs DO have numbers on them, and contacting Hyperpro-US (I'm assuming you're in the US.. if not..) will probably get you an answer.

As was mentioned - I wrote up a little info on setting up shocks on an R12R.. and you may find it useful: http://www.eilenberger.net/Suspension/suspension.htm

The most important thing to get set correctly is "preload" or "dynamic sag" - without these being correct (and they're just different names for the same setting) nothing else can be correctly adjusted.

Note that the shock travel isn't the same as wheel travel. The front has a multiplier of about 2.1x, and the rear someplace around 3x.. meaning your front travel may be 2.1x30=62mm, and your rear 3x30=90mm.

The shock manufacturers actually ignore the rubber bumper - and consider that full travel is the stroke available IF the bumper wasn't there. In that case, I'm making a wild guess that your front would be closer to 90-100mm and rear closer to ~120mm. It's possible these are different IF the shocks were installed to lower the bike's suspension (and since they are the economy Hyperpro - that's entirely possible.. bought to lower it, not to upgrade the suspension with more adjustments.)

Measuring your actual front is really easy. Put a tie-wrap on the fork tube above the fork-slider (leg). It should be able to slide easily on the tube, but then stay where it slides to. Push it down to the top of the slider. Go for a ride - with some nice bumpy roads. Put the bike on the centerstand, push down the back so the front wheel is unloaded, and measure the distance between the bottom of the tie-wrap and the top of the rubber dust seal on the fork slider. That will be your actual front travel.

Anyway - read over the link.. and see if that looks helpful. And please use some punctuation..

Aftermarket shocks can be ordered shorter to lower the bike - could be as simple as the PO bought them that way

I am in Australia.
But I understand the need to setup the sag first although I do believe, my shocks are a lower unit then standard.
Deilenberger your article is helpful in giving the manufacture base setting as a start point from which to work from as I have no instructions on the Hyperpro at all.
My last bike was a KTM SMT with infinite adjustability.
The dealer I bought the BMW from is sending me the original shocks so if the Hyperpros are short I can send them off to be modified.

Quick question: My new Hyperpro shocks I suspect need to be serviced after breakin period as their milage is now around 15k....I need my bike everyday so where in Los Angeles area can I refurbish the original BMW shocks so I can just swap them while I send the Hyperpro on east coast given that they need 2 or 3 weeks to perform the service.

A place in LA area good & affordable?

Frede, I wouldn't worry about getting them rebuilt so soon. Mine have over 40,000 miles on them and are still performing fine. If there was any oil breakdown - a very slight increase (one or two clicks) on each adjuster would bring them right back into the optimum performance. I guess sometime I might coerce Klaus at EPMPerformance to do a rebuild on mine - while I wait.. (I usually buy the coffee and donuts..)

As far as swapping the original shocks back in - that's why I suggest people keep them when they get aftermarket suspension - gives you something to ride on while service is being done on the good stuff.

Have a great Christmas - was lots of fun meeting you and Dave a few weeks ago!
