Front Fork Springs And Oil Help

[achapman01]

Hi all can I have everyones advice on my front forks. I would like to change the springs and oil (along with the seals)

I weigh 10stone without riding gear. From what I have read I think 0.85 springs and 10w or 15w oil would be about right. Does this sound correct?

If so where is the best place to buy springs?

Thanks

I think it partly depends on what springs you use - i.e Hagon recommend that you stick to 10w, while others vary.

Hagon, Racetech, Maxton as the ones I know of - google for places to buy.

Thanks so do you think the spring rate of 0.85 is about right?

[yorkie_chris]

Go lighter than that, 0.8s.

Im around the 10 st mark an using hagon .85 progressive springs with 10w oil and works well for me.

[yorkie_chris]

hagon .85 progressives? Well which are they, .85 or progressive?

[hongman]

One in each fork

[metalhead19]

Haha, ok confusing myself. Progressive. Was going to get .85 but then got progressive.

[yorkie_chris]

confusing some newbies too...

For info, hagons only come in one rate.

I way around 10st without kit and have 0.8 linear springs and 15w sv1 rock oil (look chris' I'm remembering!....or just reading the bottle you gave me)

At 10 stone I doubt if you need to change the standard springs,but I bet you do need fresh oil which will improve the front no end.

I think changing them will help. Stock are like .6 or soemthing stupidly weak.

[benji106]

stock is .7 I think. Racetech calculater reckons I need to go for .85 and I weigh 14 stone.

This didn't sound right as I recently used this and got 0.95 for my 15.5 stone (yes, lard ass I know). Just checked it again and noticed that the calculator shows the pointy SV650S as being 38 pounds (17.2kg) heavier then the curvy SV650S, so it recommends a 0.05 heavier spring for the pointy. Is the pointy really that much heavier?

I fitted 0.95 along with the emulators and with the standard spacers and preload adjusted right out the bike and rider sag is pretty much spot on (11mm and 31mm), so they can't be too far out.

I've got hagon progresive sping and 10w oil and it brilliant

I think this man has it right! If your not bottoming out your forks (using up their complete travel) then a change of oil (I weigh 11.5st and went for 15w oil) will be a great improvement unless your on a track.

I have k-tech linear 0.85 springs in my curvey and they suit me well (about 12st dressed). I use Silkolene PRO RSF 7.5W oil, which is actually about the same viscosity as most 10W oils and seems to damp well under normal road use. I don't think they would be too stiff for you, though 0.80 would be OK too, the stock curvey springs are quoted as 0.709 IIRC.

I always have a problem when people talk about fitting "progressive" springs, well yes they may well be progressive but what spring rate are they at a typical working length? At least with linear springs you know what rate they are.
