Any other shocks that fit?

Hey, I have a 02 919 with a dead rear shock, and it's getting pretty annoying. I see that there are some pricey aftermarket shocks that fit, but they seem to be pretty hard to chase down. I also posted looking for a 04-07 shock in the classifieds, nothing yet. I was wondering if there are other shocks that people have found that work. Thanks for any advice.

I thought the F4i was a bolt on replacement.

There was someone (IIRC) that bought an F4i and had it rebuilt for not that much money. Paying $100+ for a stock shock vs having yours rebuilt or an F4i rebuilt doesn't really add up. I'd go with having something rebuilt, either stock or other.

I've been running a YSS shock for years. Search ebay for "YSS REAR SHOCK HONDA CB F HORNET 900 2002-2007 SHOCK ABSORBER 344". You'll have to decide if it's too pricey or not.

Threres a guy in northern Indiana that rebuilds that shock. His last name is Daughtery, I think. Goes by Dr Suspention. Look him up. The VFR guys like him a lot.

*Edit* DMr Performance Suspention. Google that. He can fix your shock, I think.

The problem is not the 02/3 spring rate.
It's the harshness of the damper in association of the spring that is the problem.

Awesome, thanks for the info, everyone. I've got a F4i stock coming, and actually found a dude here who does rebuilds. If it ends up being kinda janky anyway, I'll probably go for one of the mid-price options.

If you want a spare---rebound adjustable 04-07 too.

Welp, I need one as well. My rear shock of 52k miles has seen a few too many jumps and NYC potholes. Rebound adjustment all the way in and it still not enough, even when the temps are cool. I'm gonna call them tomorrow and see if I can get an estimate of how many miles were on that shock before it was removed, cuz if it's 100k then it's probably not worth getting

I was under the impression that the F4i shock was automatically better than the stock 919 shock. Is that wrong?

Well, I'm kinda wondering if I screwed up the install. The F4i shock went in, but it's a couple inches longer than the stock shock that came out, and the bike has a weird lean to it now. If anyone else did the same thing, did you have to adjust anything else on the bike?

Berkeley, going to take it to the shock place over int he city if I can't get it lied up well. Seems like a shock replacement shouldn't screw up things like the chain tension, though, and the lean is pretty dramatic.

If the shock is longer than the original, you now have bike that is higher off the ground, hence the lean on to the sidestand.

The other effect of the longer shock is to make the swingarm sit down lower, changing [shortening] the distance between the rear wheel sprocket and the countershaft sprocket, hence the change in appearance of your chain tension. It will tighten again as load goes on the bike, and the swingarm flattens out as it rises.

Hmm. 2 inches on the length of the shock is a big difference...

A COUPLE of INCHES?
Based on years of info posted by many, I'd have to say that it can't be a F4i shock.

So its true that an f4i rear shock is a bolt in upgrade to the 919? What about the spring rates? What are the actual size differences? From what I'm reading the f4i shock is a bit too long, but the cbr600 f3 shock is basically a bolt in but Idk about those spring rates either

I think it's the F4i forks and F3 shock that is a direct bolt on.

I read some of the linked thread and wondered why a new piston was used, but he got a new spring.

There's a point where he gets stuck on removing a cap on the reservoir, I'm thinking that these are so cheap, someone could open one and figure out how to open and reseal them.

$274 for parts, including a new spring. IDK how much the piston was, but I don't know why you would need a new piston. Maybe the piston is a "wear item" and it's design to be replace after a while because it's softer than the cyl it runs in.

Okay, got it. I'll take that one out; I went ahead and bought the 04 919 shock that someone posted in here anyway. That's annoying, but thanks very much for the heads-up.

1
How did the free length (fully extended) eye to eye lengths compare?

2
What all did you do it before you put it on?

3
How are you finding it, in terms of ride effects?

4
Any other commentary you can add?

I don't understand the reasoning behind taking a shock from an old 600 and putting it on a motorcycle that it was never designed for. I don't know much about suspentions other than they're real easy to screw up. Then things get real dangerous, real quickly. Some things are best left to the pros.

It makes a whole lot more sense to rebuild the original.

The benefit would be a shock that is fully adjustable. And 30 bucks. And for me, one that doesn't have 52k miles and bounces like a pogo with rebound full hard. Honestly I'm not confident with "professionals." they don't know how you ride, especially if the shock was coming off a 919. There's no point rebuilding a non adjustable, non serviceable shock in my opinion. And the cost for going to a serious specialist that could probably do it right is so much you might as well get a new bike. Realistically any mods on a 919 I feel is like diamonds on doodoo. Saying that, I'd still like to spend 5k in mods one day just because I love the bike. But, every time I start to think I'm beginning to out ride the bike, I realize it was just me riding improperly. I'm starting to think that better suspension doesn't make a better rider, instead it just masks mistakes.

It is sad that the bike is great in so many ways, but falls short on the shock and forks. What makes it worse is that it's not the same as so many other bikes. If shocks were like tires, where you have a few very, very common sizes and you get inexpensive, high quality selection.

The 919 has always been known as a "pogo stick" because of the rear shock.

Nathan, Silly me.... there I go again trusting professionals, with years experience.

Just because the shock of F3 (which is even older than a 919) physically fits, how do you know wether it's range of adjustment is what the 919 needs? Have you ever ridden a 919 with the shock from another motorcycle?

The cost of a custom rebuild for a 919 rear shock is $295 from DMr. It will be sprung for your weight and valved for your type of riding. Can you get a new bike for $295?

You compared the 919 to a dodo. I will agree with that.

Just replacing old shock for 04 shock, wont do a lot better. For a decent ride, at least 04 shock oil should be replaced to a heavier, and new suitable spring installed. Coz neither original 919 shock spring is no good.

^Sounds a lot like a rebuild from DMr to me.

For clarification, the Dodo is not rare. It's extinct. They died out because they were incredibly easy to catch. Does kind of sound like a 919. But I didn't say it first. That came from a guy who owns one.

FWIW, the shock from the 04' helped a lot. The gas in the 02 shock was gone, so it was going from no dampening to some, and also a better spring.

I get the desire to leave things to the professionals, but I think it's a bit misguided here. Most shops in my area, and it's a big wealthy area, have no idea about the particular weirdnesses of the 919, and ultimately they're not riding it, you are. I find it foolish to forgo some research on how the thing works when it's your ass on the line, though of course you shouldn't assume any particular job is as easy at it looks on the internet. That's the point of this forum, yes? Otherwise it would be a static page that would say "Try to find a mechanic who knows what these bikes are."

My suspicion for mine is that I probably will go into a shop in the city to have the rear suspension tuned to me, now that I have one that can be tuned. I just picked up a suite of cases which are in Lake Co, about 2-2.5 hours on the 919, and I suspect some of those dollars will go towards a fork rebuild, too. I'll report back once I do that, and see how it feels.
