900rr fork swap
 

I'm going crazy trying to find the thread that has all of the fork conversions listed with the required parts.

I have a line on 94 CBR 900rr forks and want to be sure I buy the needed parts and what I recall is that this is a very straight forward swap. Just need to verify what I recall.

Also I seem to recall that a gullwing top clamp from another of the 900/929/954 family woks better at getting the bars "above the topclamp" pls help me verify by pointing me to the right threads.

Here's mine, but it's an RC51 conversion:

900rr everything. Gull type 929/954 top triple would be a bit big in the hole department.

This is probably the thread you're looking for:

929 and 954 are USD forks so completely different from 900rr

Thanks 7moore7 that's not the one I had in mind but it will certainly do the trick!!

Another question...the 94CBR900 forks differ slightly from 96,97 I hear it's lacking external compression damping anyone shed any light on that or other differences?

Yes, and it's also considerably lighter sprung, so unless you are lightweight, you will need new internals on the new forks, otherwise it's not an upgrade compared to stock... ;)

Thanks Tweety,

I figured I would have to do that anyway, but after reading your info the later forks are probably closer in spring rate as I am 190lbs. Oh well looks like I'll be buying springs after all!!

you want 94-97 forks 97 are better and you will need triple clamps
wheel spindle and spacers
front fender and brackets
after market clip ons or top yoke conversion to use renthal bars
be a good idea to replace fork bushes seals and springs and you will need to make a new
fork spring spacer (ali tv Arial tube works very well and its cheep)
5w oil
and head race bearings
and up grade the brakes wile your at it cbr600f4i calipers and master cylinder are the best to use

How do you tell the year of a particular set of forks? I found a stamp on the inside of the slider. It is circular with a 5 in the middle. Would that be a '95 set up?

Also, does anyone know what year 955 front fender one would use or are they all the same. And, just to make sure, you use all 955 mounting hardware/brackets, right?

Look at the lower fork leg. If there is an adjustment screw (compression) right below the lower caliper mount they are 96-97 (98 & 99 too ?). If not they are ealry (94-95) and are rebound only (screw at the top on the preload adjusters). They will all work in 900rr triples, but be sure they are pre 98 as the fork spacing changed which will wreak havoc with wheels/calipers/rotors.

Talk to me about the top yoke conversion..is that to go with old school superbike bars? And what the hell are Ali tv arial tubes?

900RR forks got compression adjustment in 95. 98-99 have different triples (10mm wider span between stanchions, different offset, different caliper mounts to accommodate 310mm rotors)

I see you have this conversion mikstr. Do you have the cbr fender or 955 fender? How much rise is in the Apex clipons? And, if '95 has a different spring rate than the '96-97, how do I know what year I have? Are the years wound differently? Are the springs a different lenth? My set does have compression adjustment.

I have a 955 carbon copy fender (ran an OEM 955 fender for a couple of years, however). The stock 900RR fender is hideous IMO.

As for the internals info, regrettably I don`t have that info, sorry. Have a look at the Racetech site. My looking up in the Gold Valve kit and spring section, you can see the OEM spring rate (is listed for each bike).

I think my Apex risers are the 3" version, set almost to max (giving me essentially the same position and VTR1000 Helibars).

Hope that helps.

cheers

mikstr knows what he is talking about, I bought the parts for my swap from him. 96/97 forks are easy to find on ebay if you are patient. The ones that I found needed to be rebuilt so they got sent to Jamie and I will have forks set up for me when I get them back. If you are going to do a swap to increase performance you might as well get the most out of it that you can

Ahh some one that speaks from experiance I hope.
I have just done the conversion to 98 fireblade forks.
A local guy made up my wheel spacers for the VTR wheels and a set for some CBR600 wheels.
I have noticed my Rotors are to small by around 10mm !
Now I have been told that rc30 rotors are the way forward.
Could I please get some advice before I buy the RC30 equipment.:(
