S2r 1k forks on s2r 800 advice

[brad black]

But does the hole in cartridge not play a function? What is it there for and what will
I lose if I close it up?

the hole in the side of the original cartridge is a compression bleed, which effectively removes the compression damping from the first 65% or so of the travel.  if you welded it up you would then have compression damping for the whole range of travel.  might need lighter oil in that leg.

the hole you drill in the gsxr compression shim stack does much the same thing, but it is smaller (1.3mm) and mimics having the damping adjuster open an appropriate amount.

from springs i have measured i'd put the s4 springs in the 0.80 kg/mm range, which is lighter than I would fit.  i'd lower the oil level though, and use 5 weight.

The adjustable forks I put on mine were billed as coming off an ST.  They measured the same uncompressed as the Marzocchis that came off.

Same diameter as the Monster forks, so no mucking about with the triples.

Ok so I am leaning towards getting s2r1k forks because I won't have to fiddle with triple clamp boring issues

I will have linear springs put it. This is the better way to go right?

Can use my stock rotor and calipers on these forks?

Better than what you have and probably worth it (depending on price and condition).

If the price is right it's not like you're going to waste money, since items like that 'easily' finds a new owner if you decide to take further steps later. Also; the S2R1000 forks are ready for quite a few levels of 'further steps' - including brake upgrades.

The S2R800 brakes fit straight on - no mods required.

you may have misunderstood some points.

all the ss, monster, st and sport classic forks are the correct size, even 900ss from 1991.  but you need the 25mm axle and 65mm brake caliper spacing.  so any 43mm upside down fork from ss, monster (2v and 4v), st or sport classic.  the upper triple dia is 50mm, the lower 54mm on all.

forks that require triple clamp mods are sbk forks from 916 onwards, which are 53mm top and bottom.  the ohlins are 53mm top and 56mm bottom.  748, 749, 848, 916, 996, 998, 999, 1098, 1198.

the st forks have a linear spring around 0.83kg/mm, which is not too bad.  in an st they need more preload, but might be ok in a monster as is for you.  s4 and s4r forks are similar in my experience.  m1000 i don't recall, i don't have them on my list.  ss1000 are the only forks in all the 50/54mm range that have "good" internal valving.  but generally all the 2v monster and ss forks have crappy two stage springs.

so i'd say st, s4 or s4r.

if you were going to get them revalved to suit you, the non adj ones are actually better internally.  like these st2 ones: http://www.ebay.com.au/itm/Ducati-ST2-front-forks-/231364904381?pt=AU_Motorcycle_Parts_Accessories&hash=item35de6c45bd

............... m1000 i don't recall, i don't have them on my list.  ss1000 are the only forks in all the 50/54mm range that have "good" internal valving.  but generally all the monster and ss forks have crappy two stage springs.

........................

The Monster1000 has the same fork as the M900.
The ss1000 has a fork with correct hydraulic lay-out, but ridicilously soft shimming.
The "progressive" spring in the ss1000 has a spring rate of about 0.6 kg / mm for at least th first 40 mm of compression (my tester runs out of range above 40 mm compression).

Best potential result for the least (but some) effort in my personal opinion: ss1000 forks with upgraded shimming and linear springs. They are longer than the Monster/ST forks, so they only work on a Monster with clip-on bars since the stock bars are right over the fork legs.

Lots of advice on "best" solutions, I´m afraid ...

Lots of good info I have been skimping through. Would these be a good set of springs for the S2R1K forks?

springs for 43mm forks need to be around 38.5mm od.  generally racetech springs the first two # are the od in mm (roughly), the next two the length in cm.  so 32mm od, 340mm long.  the box says 31.7mm x 340mm.

and 0.80 is a bit light.  i'd be starting at 0.85 for a monster with someone on the light end of average.

[brad black]

probably need a 3827 series spring.  see almost the very bottom of this:

What's would you consider a good price for the 1k forks?

Great info... Lol just when I was decided in s2r1k you got me thinking again..

Okay I don't push my bike hard. I ride around city during week and the country on the weekends.. My main objective is stopping nose dives under braking and later on when I have more budget upgrading to 4 cyl. Calipers.

So keeping in mind budget and ease of Install..

St or 1k forks?

What if I got the 1k and put linear springs?

[brad black]

St or 1k forks?

they're much the same forks, just with different springs ex factory.

[stopintime]

What's would you consider a good price for the 1k forks?

Since the ST fork, ref Brad, has linear springs, it'll save you money over S2R.

I don't follow the North American market, so I can't tell you anything useful about pricing.

Gotham has an ST fork which looks ok - at $ 500.

Will the ST forks will work with my current calipers and rotors without adjusting?

Yes
