How to: fit a BMW s1000rr rear shock to a VFR 400 nc30

[krisztian_andre]

I find compression at 5 and rebound at 7to be spot on.

Low or high speed compression, what's your weight, what's the spring rate?

I ran this idea by Dan Kyle at Kyle racing, one of the top suspension guys here in California and was told this is a bad idea for various reasons.

What is and why?

[Drunkn Munky]

Id imagine one of the reasons is that the already poor damping of the BMW shock becomes non existant once the much stiffer spring is fitted

[Drunkn Munky]

No idea but im 75kg with kit and have gone for a 500lbs spring, i originally fitted a 600lbs but it felt very stiff even without riding it. I am using a ohlins shock tho not a BMW one.[/quote

How long is the shock, how much preload is on it now, what sag is set, is it a linear constant diameter spring, what linkage is fitted, nc30 or nc35, what size is the wheel?
Sorry for the million questions.

I have the shock set to 310mm in length and use a constant rate spring. I have the HRC linkage hence the 500lbs spring and run a 17" wheel. Not got round to setting sag etc yet but my bum dyno tells me the 500lbs spring is more suited to my weight.

Anyone got a partsnumber for an ohlins spring who Will fit an s1000 shock...?

I spent hours looking for a suitable spring from various manufacturers and couldn't find anything with the right spring rate, length and tapering diameter so I just had one made to my specification.

Hi guys, has anyone had any exhaust/swing arm clearance issues with the s1000 shock fitted with the Rick Oliver HRC link? I've installed mine and the collector to connect to the rear pipe/can touches the swing arm now (admittedly the bike is still suspended by the frame from a car lift so no weight is on the shock to compress it. I'll try get a decent photo during the week.

mine touches on the abba stand but on its own weight its ok, and then when loaded with my fat ass its fine, im assuming your chain is at the right tension,

I have a tyga system and can twist the pipe to allow for more clearance.

Is that with standard pipes?
I'd think that if that happens then the rear will be too high anyways unless you have a 17'' wheel and then you'll need a different pull arm.

I had the same problem with a standard exhaust and standard linkage + bmw shock. Fitting a tyga system fxed it.
