Title: Rear wheel hop/ rear suspension?
Post by: Alan Spears on September 09, 2013, 03:23:25 PM
Went for a long ride on some dirt/gravel roads this weekend. Every time I had an uphill section my rear wheel would start to bounce and spin, to the point where I would have to slow to a first gear crawl in order to get traction. I am assuming it has to due to rear shock setting or just the fact its a stock shock (all settings maxed out) I'm a 6'2" 225 lb rider. My question is the obvious... what can I change (if any) to make this better? If stock just wont work then what works for you guys?

new shock is desperately needed ................... :bug_eye
it has probably been the contributor to your light feeling front end also

Is there a consensus on which rear shock to get for an 02?

The hagon is going to be the least expensive .......about 600 bucks for one that has remote preload like the oem on your Girly

Link for Hagon in the USA  http://www.davequinnmotorcycles.com/cgi-bin/webc.cgi/HAGON_MONOSHOCKS.html
ohlins are unobtainable for girlies
wilbers are good but you are going to need a second mortgage
penske is going for 800-1200 bucks


the aftermarkets are all good compared to the OEM unit
depends what you want to spend

At your size and weight I would avoid the Hagon and anything else that doesn't have a remote reservoir.

Tigger has a long swingarm and no linkage so the shock has to work very hard. Once the oil overheats you are back to where you were with the stocker.

I'm about to replace my Hagon with a Wilbers tp try and eliminate this problem. You are welcome to grab my Hagon to give it a try, it will be cheap, but really you should just bite the bullet and do the job properly the first time.

The good thing, that mortgage doesn't have to be on a big estate  :icon_wink:

Buy the time I add freight your Hagon may indeed be as expensive as the Wilbers.  Are you having traction/hop issues with the Hagon?

My suspension expertise extends to the ability to identify a shock absorber at 20 paces but the OP said that everything was maxed out on his original shock. I presume this to mean preload at amx and rebound damping at max.

If I understand how rebound damping works, having max rebound damping would encourage a 'hopping' effect because the shock can't rebound quickly enough to be ready to absorb the next impact making the rear bounce off the bumps instead of absorbing the impact.

that makes since... I was given that advise from someone I believe is a pavement only rider. I just went out and cut the rebound in half, I will ride some rough roads tomorrow and maybe that will help until I save up about 700!

Too much damping also causes "pump-down".   If you hit enough bumps in a row and what you described occurs, the travel gets less for every bump because the shock has no time to recover, eventually it locks at the minimum travel point and you now effectively have a rigid frame, no suspension.  As soon as you clear the bumps it clears itself until the next lot, and so on.....

My shock appears to be "working" as it does dampen. My question for you guys is how will a new fancier shock help?

The most notable change after fitting my Hagon was a lot less ear-ache. 

Mainly due to the talking ballast getting a smoother ride..... :hat10

Yeah I'm still getting the juddering with the Hagon. I can dial it out a little by winding up the damping, but ride on a rough dirt road for more than about half an hour, the oil overheats and I'm back to no damping.

This is why I'm thinking of a more expensive remote reservoir shock

It will certainly help drain dollars from the bank. I'm not an off road guy (except for today :icon_frown:) and our roads are reasonably smooth so a new shock is way off in the future for me.

Despite both BMW with their ESA and Ducati with the Sky Hook active suspension we are a long way away before we have a suspension setup for all synarios,hence why the one that's works for hi speed on a tarmac road doesn't work when offroad,having test ridden most of e'm of recent including the 1050 sport I was more than happy to get back on my 955,but hardly suprising a stock shock for a production bike comes in around $100 or less an aftermark is rather more because your paying for whats inside and the adjustment you have on the outside.

Being ever the tinker'er (sp?) What would be the level of defference between a stock shock with 18K miles and a mid-range aftermarket shock?

All the difference in the world. I have a white power shock on my 885i and it's amazing what the difference is. I thought it would be like car springs, aftermarket are stiffer and that I didn't want, but no, this just made it easier to ride 15mph faster everywhere!
