Anyone here have the part number or a place that has the correct springs for my weight?

I have a 2007 S2r1000.

Please let me know. Thank you. 

Front or rear?
Your weight

Front springs needed.

I used to work for a carnival... I guessed peoples weights. So I'm going to say...


273 lbs.




Right?

right numbers, wrong order

327 i say!!

Seriously, I purchased Racetech stuff. And the model springs that were used in my bike was...FRSPS373210 1.0 KG/MM Fork Springs those forksprings are model number FRSP S3732 so the last 2 digits designate teh spring weight.

for valves i had FMGVs2043.

Both are for an S2R1000 2006 stock showas.

Were spacers needed for your forks or did the springs just drop in?

drop in.

i would like to do my forks too but am a bit apprehensive.  did you install the springs yourself?  any tips?  special tools?  or tips to avoid buying special tools? i have a manual i have read through the section a few times but just havent bit the bullet yet. 

btw i am no stranger to suspension components, i worked as a mechanic in a bicycle shop for years and have torn down many a high end fork (and have gotten into a a set of 3" Fox off road racing shocks when i worked for a CORR team to many times to count)  so i don't think i will have any issues, i just need someone to push me off the ledge. 

also, 210lb geared,  what rate should i be looking for?

i had a shop to do it, i didnt have the tools to suspend the front of the bike or a tool to open up the forks Theres this really werid tool that slowly opens it up, like a spring compressor.

I took my S4RS to the shop, Irvine Spectrum to be exact. They did a great job. They installed the springs without taking off the forks. I'll do the same once I get the springs for the S2R.

ICON........ you can't change them...................














You promised to keep the S2r stock

i heard the same thing. lol

True, very true. It is just that these springs are excessively soft. I use the S2R as a cruiser and to ride my daughter around town. The other day the bladder was hitting some speed bumps hard with her on the back...not good.

....and this is a good opportunity to get a Penske rear shock too.

Hmmmm......... I think I saw a used Spark mid-pipe for sale in the classifieds...... cheaper than the suspension & you can still run the stock cans & keep it quiet & somewhat stock looking...........

replace the springs, it should be one of the first mods most people make.

spring stiffness - k = Gd^4/8nD^3, where d - wire diameter, D - mean coil diameter, n - number of coils.  so to make the springs stiffer, they need to increase the wire diameter or decrease the mean coil diameter or number of coils.

most aftermarket springs will just have less coils, so they're shorter.  meaning you need to make the preload tubes longer.  some springs will come with alloy tube that mimics the std showa steel tube you can cut to length and reuse the original plastic bush at the bottom.  or you can use electrical conduit or appropriate size, that sort of thing.

back now, i got interrupted earlier for a few hours.

i'm 95kg or so - which is 210 pounds.  i ran .80 kg/mm springs in the marzocchi 40mm forks with 30mm preload on the springs.  that gave 7mm static sag (under bike weight only) and 21mm sag with me on it.  so my 95kg plus the bike compressed the springs 51mm.  51 x .80 = 41kg on the spring.  so theoretically there's 82kg on the front end with me on it.  in my 41mm showas i have cut down original 94 900m springs.  std is 0.70kg/mm, mine are 5 coils shorter than std (19 to 14) and have been tested at 0.86kg/mm.  i thought i had 13mm of preload on them, but due to the cut down end of the spring settling about 1mm with slight load applied, i had about 12mm preload.  sag was 13mm static and 35 with me on, giving a total compression of 47mm.  47 x 0.86 = 40.5, about the same (luckily for the theory).  30 to 35mm total sag is what i wanted.

if you had adjustable preload (mine don't) that'd be fine with the adjusters fully out so you could wind it up from there.  there's no point going any softer than that, as you'd only really want to go harder.

you need to detirmine the required preload spacers for the new springs with the springs fitted.  you measure how much spacer you need to take up the distance between the top of the spring and the bottom of the spring retaining collar then add the preload and make or add the spacers to suit.  if you'd done it once before for a certain spring and fork combo it'd be something you could make up, but for us it's a check and do as you go thing.  then you assemble them, fit them to the bike and check the sag, redoing as you need to.  i made mine up for the showas from the above formulas based on the info from the .80 springs in the 40mm marzocchis.

dunno if this helps, i think i started rambling.
