CBR900 Rear Shock woes & advice

[wots]

Carvel rode my bike at the weekend and pretty much confirmed what I already thought, the shock has seen better days. It's particularly bad first thing in the cold, it can crash over certain types of bump, but does seem to ride the road fairly well normally. Being a slightly better rider than I, he noted that it just wasn't right.

I bought this bike very cheap and it hasn't really cost me much in a year, I ride it most days and it will never be a minter. I want to sort the rear shock, but the cheapest new shock was about £250 for a.n.other branded sports shock (I think this was gas, no reservoir). Secondhand shock is a waste of time and money, might end up with the same or worse. Considered rebuild, but these aren't really designed for rebuild, which means sending somewhere and probably costing at least half the cost of the new.

Any other options/suggestions? If it was a mint bike, I'd buy a new shock and be happy, but £250 is a quarter of what the bike cost me.

CBR900 RRW (I believe the shock was the same on RRT to X)

Plump for a Branded one, you're essex way from what I remember, Hagon in Hainault do one for £300

If you want cheaper risk some SH ones other wise that is the best option IMO.

As usual everything is extra, so no matter how reputable they are, they've got your shock and can insist on certain extras being required. Just a couple of things there would push it way above £250

Hi
Had one of these baby's, on and off for the last twenty years(!), my only keeper. I've rebuilt this one up from a frame and engine.
The rear shock is, as you say, pretty much a sealed unit and, as you say, anything S/H is very likely going to be as bad.
Given that your shock is not a corroded mess, I take any suspension stuff to:-

They rebuilt mine for £130 a few years ago so might be more and there's postage too. BUT, they remake them to be re-charchable easily, unlike the originals and I can garauntee that the difference is quite amazing.

There is another consideration, the shock has top and bottom bearings, yes? These would come with a new shock, so I wouldn't have to source separately and if it's the same ones as I found, that's another £40. Making the replacement seem all the more attractive. Or am I, as ever, talking nonsense?

£120 for a rebuilt stock shock sounds about right but, there must be quite a few used aftermarket shocks out there. I picked up a Maxton shock and front forks for very little not so long ago so get searching

Brooks will do a proper job, but it won't be cheap. However I'd rather have a rebuilt OEM shock than a poverty aftermarket one.

for £135 all in I don't think you can go wrong

I think I may have something sorted, thanks to someone on here, watch this space.

As above, all sorted, obtained a secondhand one that had only been on a bike for a couple of K after being replaced with a Maxton item. It's in perfect condition. I've paid a fraction of the rebuild cost, so I'm happy.

Hopefully I can fit it next weekend, it looks dead easy, as I've got an Abba stand so It should be easier to fit.

Just need to find the default settings, I think it's one turn off hard.

Just to make a point. You will need to suspend the back of the bike from a hoist or similar. Once you take the shock out there is nothing holding the bike up.... Or am I stating the bleeding obvious?

Although, I did use a chunk of wood between tail unit and tyre when I had my shock out on the ER6, however that is offset and a piece of piddle!

If you are making the effort to replace the rear shock,it would not take too much more to have the swing arm and linkage out and to clean/grease the bearings.Especially if you have not done them before.

As you say,it helps big time that you have an Abba stand with the right adapters

Already ten steps ahead of you

As it happens, my fireblade has a black frame, which was sprayed by a previous owner. I managed to bag a swingarm on eBay which had been powder coated black and never fitted a couple of weeks back for £25. Glad I got the Abba adapter kit, for just such a scenario. It actually looks fairly straightforward to do.

It is the linkage bearings and spacers that were my main thought.The ones on my R1,although they were only 2,200 miles old,that were corroded

This was quite a shock to me.But then it did underline the fact that bike makers do not use much grease on assembly.For whatever reason,it does look as though no grease was used at all,so I caught it just at the right time.

Is that the shock that was only used for 2k miles ja It's certainly had a good clean up
