Re: Help

So, early blade shocks look similar, but are longer...

Fireblade shock lengths

CBR 900 RR 1992-1995 319mm
CBR 900 RR 1996-1997 305mm
CBR 900 RR 1998-1999 303mm
CBR 900 RR 2000-2001 286mm
CBR 900 RR 2002-2003 288mm
CBR 929 2000-2001 286mm
CBR 954 2002-2003 288mm

These shock lengths (courtesy of this or another forum) may help...

A few extra millimetres adds up to cms at the tail end...

Re: Help

Have you got the right length shock?

If so, check the triangular plates are the right way round.....they are not equilateral triangles, more isosceles....

Re: Help

Thanks I think I was looking at it the wrong way I will try to move them around to get a better result. Well if that doesn't work how should I deal will it if the two results don't work. Different size shock or changing the plates I would need some serious help lol. Thanks guys Arthur

Re: Help

We've recently had this discussion here. It's very easy for Ebay sellers (not saying that's where you got your shock, but just as an example) to "think" they have a shock from 98-99 900's, when they have no idea that the 93-95 was longer, 96-97 was shorter, and the 98-99's were shorter still.

If you truly have a 900RR shock and your bike now sits too high, you have the older, longer shock from 93-95.

Generally when you swap out the shocks the triangles don't need to be removed, but if hey are as Sax said, there are directional arrows on them because they are not equilateral.

Plenty of able bodies here to help you out with whatever you 900 offers to drive you nuts.

I'm thinking most likely an early 1992-1995 shock...

But could possibly just be a shock that looks similar (or came off a blade - but was put there by someone else - rat bike/streetfighter etc)....

Or, when the shock has been changed, shock plates removed and not put back correctly....

(easily done, I have done this myself on an SSSA conversion.....where I ended up rotating the plates back to stock, and then making new triangular plates to suit - but if you are going to do this, the bikes geometry and rising rate suspension may not remain as Mr Honda intended)....
