Help identify my fork

Recommended Posts

Hi there, can anybody help a newbie with a KYB fork question.

Got a second hand KYB forks and are lost, they ned to be overhauled but I can`t identify the year. According the previus owner they where used on a YZ250

2 or 4 stroke? nor the year or if they belongst to that bike.

They appear to be closed cartridge type, means they have to be at least 2005 or newer.

All help appreciated!

At only 43mm in diameter (lower tube), that is the first clue that those are not late model 2006+ AOS SSS forks 

and are actually many generations older in design. (early to mid-'90s)

 

According to the KYB parts catalog, in Yamaha applications

the 43mm diameter forks were last used on the 1995 YZ125 & 250.

 

Again from the available infos:

 

-1991 to 1995 : 43mm open chamber

-1996 to 2003 : 46mm open chamber 

-2004 : increased to 48mm but still open chamber 

-2005 : 48mm closed cartridge fork introduced (AOSS design only used in '05 model year)

-2006 to 2018 :  48mm AOS closed cartridge fork, Yamaha markets them as 'SSS'

Greate and thanks. These are 46mm+ (see first pic), should be 96-03 open camber according your info.

Not open them yet, but easy to determine if they are closed or open. But looking at the fork cap it could look like they are open. 

since no internal cap wrench  is required or in fact I don`t have a clue just wild guess

Sorry my mistake, the 1st pic being upside down I mis-read the caliper,

so yes 46mm gives you a time frame on what bikes/years they might be from.

 

KYB doesn't list any closed cartridge fork with 46mm tubes, only 48mm. (2005+)

Hi, You`re right. A search on KYB parts catalog, these forks came up with 46mm innertube and the same seal parts nr.

Only WR used them to 2004. and Honda to 2007. But searching trough KYB fork cap image I cant find one similar to mine

Are you able to se if the lower fork section is Yamaha? because I also need the lower plastic fork guard .

Yamaha:

YZ 125/250 - 96-03

YZ 250F - 01-03

YZ 400F - 98-99

YZ 426F -00-02

YZ 450 - 03

WR 250F -01-04

WR 400F - 98-00

WR 426F - 01-02

WR 450F - 03-04

Kawasaki:

KX 125/250 - 96-01

KX 500 - 97-04

Honda

CR 125R -97-07

CR 250R - 96

CR 500R - 96-02

XR 650R - 00-07

Suzuki

They seem to be Paioli forks, made in Italy. May have come off one of the Belgarda built Yamahas like the TT600

Certainly not off a YZ250.

Hi, good news thanks to all. Paioli and Kyb formed a joint venture back in the late 90’s which keep on produce the open chamber 46mm. Not sure if it’s stil alive but Kyb has also formed a JV with Yamaha in 2012 which mean they are the OEM producers of shocks for Yama under the Yama/KYB brand. However, thanks for narrow this in for me..learned a lot. Now I just have to find the plastic parts (fork guard)
