rear shock spring rate
hi everyone
new to form what great info you guys have
the stock shock so the book says is sprung for 180lb rider
does anyone know what this translates to in spring rate
looking at buying an aftermarket shock on ebay and it says
the rear spring is 900lbs and I have no idea what this means
in rider weight.
also I added pic of my hawk to profile when I post it dosnt show it under my name like others do

the spring rate is based on bike+rider+gear+riding style.
i have a 1k spring @ 180 lbs give or take and set aggressive ( track )
the preload adjuster is in the upper range so my guess a 900lb spring would be good for around 150 lbs rider.

I went to race tech web site and they dont even list the vtr1000 in
thier list of bikes. the shock im looking at is on ebay and its a fox racing
shock. The stock emoltion single adjust shock on my bike leaked the
fluid out while the bike sat on my lift for some time and I wanted to upgrade so I bought a rc51 rear shock for the double adjustablity
and with the proper provisions made it fit the bike but the spring rate
was about half enough for that bike so after you respring it and revalve
it you are not far from spending enough to buy used after market.

that's weird. i found it... go to search, spring rate search and select what you need. It's listed under street, then honda, then VTR1000F

The stock shock spring is indeed a 16.4kg/mm (918lb/in). I calculate that as being good for a 161 pound rider. Here is a table that I've put together that might help you with spring rate selection:
Rider = Spring Rate
95-130lb = 850lb/in
130-165lb = 900lb/in
165-200lb = 950lb/in
200-240lb = 1000lb/in
240-275lb = 1050lb/in
If you want the Metric rate just divide the lb/in value by 56 and that will give you kg/mm.
I hope this helps!
