What spring do I need? CRF 50

Anyone know a cheap/easy solution to cure the bottoming out on my 50? I don't want to spend $200 for an ishock......Brett told me he thought I could just change the spring on my stock shock to stiffen it up some and give me some more travel..... I am 175lbs and the stock crf50 shock will barely hold me, if I hit a bump, it bottoms out easy.....I don't want to make it ride TOO stiff though....I don't need it to jar my freakin spine outta place....

Your thoughts?

I see a lot of people running ishocks but they are $$... I just need something cheap to get me by....I will not be pulling the forks off for springs...just want to add some spring to the rear right now. Anyone else know what spring I can get for the stock shock or is it imperative to buy a new shock?

Anyone have a good used ishock or the equivalent laying around?

If you change the spring/shock, say to an ishock, doesn't that raise the rear of the bike up? therefore requiring modded forks for the front to match it?

I don't want to get into all that......just need it rideable really but don't want it so freakin stiff it kills me over every bump...

How about this? not bad for $50 but it says its for stock style extended swingarms..... I wonder if it would be way too stiff for a stock length arm?

Thoughts?

So the fast ace shock would work ok with the stock swingarm and stock forks? and yes, I am definetly trying to cheap out....... I just want to ride it without bottoming it out and without jarring the discs outta my back.. Will the fast ace really bolt right on or is mods required to the frame/swingarm?

I doubt that it'll change the ride height. The HD spring should be the same length as OEM otherwise it wouldn't fit.

I believe the iShock has an adjustable preload setting so you can raise the rear a little but not to the point that you'll need new forks.

that shock will work fine, it will raise your ride hight about 1.5-2", it will be a little stiff at first, but will be fine after break-in.


To all the "name brand" nazzi's out there, I have personally broken an I-shock in half(I bought it new, used on a stunt 50, not off road), and have two other I-shocks in my garage that are broken right now. The fast ace rear shock is far superior to the I-shock. I replace all my broken I-shocks with them.

to fit a stocker you need:
10.5"(270mm) and a 250# spring, non res type fit fine.

Josh, that is the shock that I bought.....270mm/250lb. I ended up getting it for $87 shipped. Looked like a pretty trick piece to me and is said to work with the stock swingarm/frame. We'll see....hopefully I can soften the settings up on it some so its not bone jarring stiff...

you may have to grind the spacers on the shock a little to make it fit in the swinger and frame, easy. (some of these come with thick spacers for aftermarket apps)

I put the FOX Float on the 50 last night... frikkin' cool dood! Air volume and air pressure is adjustable from 20psi to 300psi...

Now my front needs to be raised... I was thinking of a TwoBros 1" taller/stiffer spacer/spring kit. Anyone have experience with it?

let the air out, if it is too stiff. All the air/nitrogen does is put pressure on the oil chamber.

I got the Fast Ace shock on today...Took a little grinding on the spacers to get it in there but after that, it felt good right out of the box. Pretty much what I was looking for....it supports me but its not TOO stiff....My 250lb buddy sat on it and couldn't get it to bottom out so...Lets see if it holds up..I haven't played with the settings or add any air to it yet but it feels good for now.
