Default HOW DO I SOFTEN MY SUSPENSION UP?

     

I have a cr 250 and the suspension is too hard. I am only 120 pounds so i need to soften it up. I know how to adjust the suspension of the forks...but i DO NOT know how to adjust the suspension of the rear shock. I am not going to buy a new spring or anything... so i am going to try my best to soften it up.

At 120 lbs, I'm thinking a new spring is a must. Maybe someone will post up about how you can get by without buying a new one.

Pretty much the only thing you can do is change the spring. Or gain some weight. Or just start going a lot faster and riding harder to use what's there.

Honestly, no amount of compression or rebound adjustment is going to compensate for too stiff a spring. At 120lbs you are about 40lbs below stock spring rates.

My son was in the same boat. The bike would throw him like a rag doll. I got him a spring for a Christmas gift a few years back and wow, what a difference in his riding. I really thought, in the beginning, that he just wasn't a good enough rider for the bike, but once we redid his rear spring rate, it was like night and day.

I think the only way to fake out your suspension without changing the springs is to back off of the spring preload to get the sag in line with normal, back the compression dampeners all the way out and run your rebound about 1/2-3/4 of the way in. This will give the bike a slightly softer feel, but it's not correct. The bike will not be stable in the rough stuff and it's not going to handle the way it could if the suspension was done properly.

You asked us to forget the weight - the simple fact is that you really can't. It is one of the fundamental factors in adjusting any suspension.

We aren't trying to be harsh but what you are asking for is simply not the way to go. We know what you are trying to do but the simple fact is that sometimes ignoring physics just doesn't work.

You can get them from pretty much any suspension shop, but my favorite place to get them is from Dirt Bike, ATV and Motorcycle Parts & Gear | MotoSport Though you'll need to call Factory connection or use the MX-Tech.com - MX-Tech Suspensions – Motocross, Enduro & Supermoto suspension spring rate calculator to figure out what spring rates you need.

They run around 100 for each end = $200.
