Rear Spring Rates

[Jester666]

I'm looking to change the spring on the rear shock and need some advice pleeeze!!

I'm approx 14 1/2 stone in my gear so what spring rate should I be looking at? lbs/ins or N/mm is fine.

And what length is the spring?

I know some people have gone for Jacougar (spelling?), I'm looking at Faulkners.

The internal diameter of their springs is 2.25"/58.5mm, is this ok?

Thanks Guys as I understand bugger all about the dark art of suspension, its all wizards and pixies as far as I know!!

Check out the Racetech Web site (http://racetech.com/VehicleSearch) as they have an on-line spring rate calculator. You enter the bike model, intended use (road or track) and your weight and they give you a recommende rate. Easy as pie......

I have a spring from Faulkners,Good value but will not fit a standard shock,some say a spring around 800-850lb is OK for them but I have found that the 920lb (stock) after a bit of use works best (12 stone).

Stock will still be stiff.

Jester, I'm not sure off the top of my head, but remember the standard Firestorm shock does not have a parallel spring. One end has a smaller diameter measurement than the other.

The Maxton spring I have fitted get around thing by using a reducing collar.

Was thinking the same thing, looking at the calculator I'm nearly too effing big to be riding the bike even with modding the suspension lol FML!
