R6 rear shock vs BMW S1000RR

[justanothernoob]

Ladies and gents, boys and gals ...


I understand that there will be some machining / jiggery pokey to fit them, that both will need up-rated springs and that both are a considerable upgrade over the stock FZS600 rear shock. And while I know that some feel that the stock shock is fine with the correct spring, I like the thought of an adjustable shock.


So far the BMW is winning my vote as it's slightly longer so will jack up the rear (perfect for my streetfighter project) - whereas the R6 will lower it.


What I'm after is how their performance compares against each other: anybody got any first hand experience?

Why yes, actually 

You won't get a BMW S1000R shock to work properly on the FZS600, it's just too long at about 325mm and the damping is way too soft as a result :

Having said that, the latest version of the shock is about 10mm shorter and might work ok but I haven't tried it myself.

Your options in order of cheapness are:
1. 2001-05 FZS1000 rear shock with 600 spring fitted. Plenty around and better than standard 600 shock. But there's a reason most 1000 owners dump them ...in favour of an R6 shock.
2. 2008 onwards R6 shock. Best value adjustable shock but as you say, little scope for raising the back-end too much, certainly not much more than an inch over standard height.
3. Aftermarket. Plenty of choice here. At a price...

I've fitted the later BMW shock and fitted a harder spring (not sure what effect this will have on the damping) If you go this route you'll need to hit the centerstand bracket with a grinder as the lower linkage hits the bracket. The shock needs filing around the top mount as it wont line up with the holes in the bracket on the frame until you've removed some material. The coolant reservior needs either modifying or relocating and you'll need adjustable (or the exact length) dog bones to stop the shock hitting the cross brace on the swingarm.

Other than that its a straight swap............

It may be slightly cheaper than the R6 etc swap but straight forward it isn't.

Hagon rear shock off the shelf. Fits straight on, good performance, reasonable price......

Iv just received and fitted an r6 shock from kebab. Haven't ridden it yet. Waiting for dry track. But the conversion is good and feels quite a bit stiffer than the standard shock.
