All 2st sachs or ohlins ???

hi folks ive got a dilemma , being a big lad ( 6ft 2" and 16 stone or 224lbs for the none brits) i cant seem to get the rear suspension to sit correctly ie high enough i have a 2002 cr 250 and love the bike but hate the look of it when im sitting on it its just too low so i have the chance of buying an ohlins shock which ive been told will be harder and raise the over all hight of the bike ever so slightly, preferably i would like the bike to bigger and harder any help would be much appreciated ps i have the hardest spring in the standard sachs shock which was regassed and serviced before xmas

The brand of shock is not your issue. The spring rate is. If you get the correct rate spring for your weight the bike will sit correct.

i got the hardest spring fitted to the shock when it was serviced before christmas john or so i was told

Have you cranked down the spring and set the sag at 100mm? The brand of shock doesn't matter...an Ohlins isn't going to make it sit taller. I'd try to find out what rate Sachs spring is on your bike for sure. I can't remember what spring I used on my 02 CR 250 but you're not tremedously heavy...I think stock is a 5.2 and as a 185 pound Pro Motocrosser we used a 5.4 or 5.6. You might only need a 5.8 or 6.0 and you can get up to 7.2 I know they have a variety of springs...maybe you can find one off of a Husky 570 that would be heavier. The spring you've got could be bad too.

Easiest way to tell if your spring is too soft is to set your sag with you on the bike at 100mm and then check the free sag with you off the bike. If your free sag measurment is 20mm or less you need a stiffer spring.

The PO of my bike was 200 lbs. and he had a 5.6 on the shock.

Thanks Cagiva WMX
- May I ask what spring you used on the '02 fork and your oil height?
Thanks

Try to find out what the spring is. I know that when you get in to the higher rate springs a mere 225lbs won't even make it move.

Yes, I think I have all that information. My suspension was done by Fast By Ferracci that year and the sticker with all the fork info is still stuck on the wall in my shop!

If you are 224 with no gear you're going to probably need a 6.0, a 5.8 may work but my experience is that a stiffer spring with less preload to get your numbers SAG right is the better way to go. Keep in mind that springs can vary a bit so having them tested to see what rate they actually are will save you some time. When you get the correct spring your preload will be close to 10mm with static SAG @25-30mm and with you on the bike you should get about another 105mm for a total of about 130-135mm. From there you can tweak it slightly to your liking.

My 02 CR 250 came from FBF with the suspension revalved. .48 fork springs 80mm oil height. Compression and Rebound both at 15.

A 6.0 spring with 12m preload and 200psi gas should do you about right.

Wow- thanks a million.
Great data- actually have a FBF sticker on this current fork['02 cr] but cannot make out the settings.
Thanks again for the help

Ok I have a 5.4 spring fitted and have phoned my local husky dealer and they said that is the hardest spring they can supply for this bike????? I've looked on eBay and there are no springs for sale???

Does anyone know where I can get a harder spring ?

the answer to every husky question

What about us Europeans? how much does a stone weigh? could you please use the metric scale.

224/2.2=101.8

OK, I did a little research (I used to work for a suspension shop & not being able to get stiffer than a 5.4 sounded a little odd to me).

For your weight you should have a 5.8 (offroad) or 6.0 (MX) on your bike. These rates are available through Eibach only.
Factory Connection (866-220-1151) should be able to get you one.

one stone = 6.35029318 kilograms

I wish that all of us could agree to use the metric scale.

One stone is the weigth that a man can carry under his arm, WTF?

How about the weigth of one fish?

I think this is really stupid.

What is the size of the stone, or the fish.
no one knows.
