Hi guys

I've had my suspension revalved and sprung by a very reputable tuner in UK. I was just curios of other persons spring rates......
Basically I'm 78 kg with out gear, the bike has now been fitted with lighter springs front and rear, .48nm on the rear, in which my sag is set well, 28mm and 100mm. And the front they have put in 4.3nm, oil level 340cc. The shock also has a 3mm lowering spacer.

Anyways, just spoke to/read various articles, and they all recommend stiffer fork springs.........
The rates I have seem a little low, I'm an int/exp rider, the bike feels to be ok, was pretty soft on the front end, I've added 10mm, which has helped the bottoming out.

Just after some feedback really. Thanks.

those springs are a little soft, do you use it ffor mx?

I hear alot of people that say the shock spacer is not needed on the 1012.

Yeh using it for motocross.

And yeh I've also heard spacer not reqd on 2012??

Stock springs are good for your weight and lowering spacer is not needed as mentioned before. Both ends are on soft side in stock form.

I'm amazed you get those sag readings!  What are the fork sags?  I'm 68 kg and use 5.0 and 0.46

On a ktm 350 however

When you say shock spacer are meaning the shock linkage?

Mog- I'm amazed also, as I've used a 52 in the past. I'm unsure of fork sag, but I've always used 52nm rear, and .46-.44 front, that's why I've found this set up a little strange... The springs were tested and that is the rates. (apparently) but recommended only 330ml of oil also..... I've added 10mm as it just bottomed out regularly.

Rich bing- spacer is inside shock, 3 mm to lower the back end, linkage is totally standard.

I found 0.44 forks soft on a rmz 250!

2012 Crf 450 really needs stiffer fork springs, at least 4.7N (std 4.8N). We use 54N shock spring for 70kg riders with sag numbers 40mm/100mm. Do you have stock spring seats (and not for example TPS or pro circuit).... just wondering that low oil volume recommendation. But anyway believe me you need much stiffer settings to feel it comfortable....and this bike doesn't have stink bug stand like it was 2009.

Yes it's stock spring seats.

I'm now going to get the bike set up completely stock, valving,spring rates etc and start again I think as I'm not convinced on this set up atall.

No, some suspension shops use the link while some other use a shock spacer inside the shock to limit the travel. It's a different approach but it is meant to correct the same problem.

OK. I just now more people use the link for handling and balancing the bike. I just don't that many that use a shock spacer.
