At what rider weight is the Monster (S*R) sprung for?

I've heard that the Monster is sprung for an Italian teen at 150 - 170 lbs.  Is there any truth to that?  I am probably 145-150 with gear on.  Is there a need to change out the rear spring for different rate while I am swapping the S4R shock in?  or even for a different type of spring? 

Also, what's the concensus on front fork springs and/or revalve?  Not looking to race or anything.  Just twisties and the satisfaction of modding.

That about right. I believe the S4RS is sprung for 165 lbs.  15lbs light should be okay.  You could ease on the preload a bit to make sure you have the proper sag.

At 145-150 geared-up, you're OK with the stock springs.

They're not great, as the rear is a progressive spring and the OEM springs in your S2R1k are dual rate.

Hi, was just reading this post and had a couple of questions, I have a 07 s2r1k I am 200lbs with gear. I bought it last spring and have not been happy with the forks and springs. My tech told me that I need to re-spring the front but he said the rear is ok. At my size do I need to do both.

Need to clarify this a bit here.

S*R covers a few bikes, and they're not equipped with the same suspension.

S2R800 and S2R1000 are sprung similarly, progressive spring on the back, dual-rate springs on the front.
They're pretty softly sprung.
They can be re-sprung successfully.
The S2R800 forks leave a good bit on the table due to their crude design.
S2R1000 forks are fully adjustable and can be revalved.

S4R is sprung a good bit stiffer, epecially the front.
They can be re-sprung successfully.
S4R forks are fully adjustable and can be revalved, they're virtually identical to S2R1000 units, but are a bit more harshly valved.

S4Rt seems to be sprung about the same as the S4R.
Forks are physically a bit different but still fully adjustable, haven't been inside a set, but AFAIK, they're revalveable.

S4Rs is Ohlins front and rear.

At 200 lbs, you would be best off respringing both ends.

Thanks for the info I'll talk to my tech about options

Thanks guys.  Sounds like a valve job and and maybe some better spring for rear shock will get it done.
