Fireblade Shock Conversion

[21st Century Boy]

I've read a few of the previous threads about changing the original shock for a CBR 900 shock and it has been suggested that a 929 or 954 shock will work.

Are there any mounting / clearance problems with using a 954 shock that has a fixed reservoir at the top?

Many thanks

Better read more carefully then!

Here are the lengths of the shocks...

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

Measure yours to compare. But you should also consider the spring rates and damping valving. The blade shock is for use with a linkage system and so is no good unless you can figure a way to fit your original spring, or one of comparable strength. As shown here fireblade springs are about 750lb/in and CB-1 springs need to be about 1100lb/in, so the bike will ride awful if you try to use the fireblade shock as-is. I have ridden one where this was done and it was indeed awful, boinging like a pogo stick.

You can't fit a shock with built-in reservoir, it'll crash on the battery box. It's hard enough fitting a remote reservoir.

Ok, i see.

So what about swapping the cb-1 spring onto the Fireblade shock?

This has been mentioned in threads but what year 'blade shock is best suited with the CB-1 spring....?

Or is it just a case of measuring the original and trying it??
