rear shock sag under bikes own weight
I've been told that the bike should sag 100mm under it's own weight. Does this sound about right. It's a 02 ec200 with a ohlins rear shock.

20mm should be closer.
100mm sag with rider is normal for many dirt bikes.

I have found the rear suspension works much better if you have about 30mm+ of sag with no rider on.
Sag with the rider can go up to 120-125 mm. Try this set up - it works amazingly well over square edged bumps.

100 mm seems very excessive, but I don't think the amount a bike sags under its own weight is relevant. It only matters how much it sags with rider weight. The amount the bike will sag under its own weight would vary with the spring you have installed. With the bike properly set up for a heavier rider, the bike wouldn't sag under its own weight as much as a bike properly set up for a lighter rider.
Again, I don't think that the amount a bike sags under its own weight is relevant, but unless it's sprung for a toddler I wouldn't think it would sag 100mm. |

Try and work between 8mm and 10mm of shock spring preload.

Here whats confusing.A target of 8-10 mm preload is only effective if the rear spring is the correct rate for your weight and or ability to start out with. So you first must be able to have 15 to 30mm free sag at 100 mm race sag as a baseline setting. Only then can you back off the preload to 8-10 mm which will of course change you race sag to 120mm or there abouts. You cant have it work properly if you dont first start out with the correct rear spring.

Yes, thats right. Correct spring is assumed. Your weight and spring rate?
