Stretching the suspension travel.
Im looking at getting into a 990 adventure shortly and am doing my homework on suspension first.
From what I understand so far (I may be wrong) the 9x0 series run the same forks/shock as the later 640 adventure.
The early 640 adventure had 300/325mm travel while the later ones have 270/310
I have heard of someone 'replacing the rod' on a later 640 to get the same travel as the early.
Is this just a case of using an early 640 rebound rod to gain extra travel?? or is there far more involved. Furthermore can the same be done to the 9x0 forks??

Whether the fork is internally the same I'm unsure. The RFS bikes use the 48mm forks but they are not internally the same. The fiche cross reference at MunnRacing should tell you all.
2003/2004/2005 950 230mm travel front/rear - 880mm (34.6") seat height
2003/2004/2005 950S 265mm travel front/rear - 915mm (36") seat height
2005.5/2006 950 210mm travel front/rear - 860mm (33.9") seat height
2005.5/2006 950S 245mm travel front/rear - 895mm (35.2") seat height
2006 990 210mm travel front/rear - 860mm (33.9") seat height
2006 990S 245mm travel front/rear - 895mm (35.2") seat height
2007 990 210mm travel front/rear - 860mm (33.9") seat height
2007 990S 265mm travel front/rear - 915mm (36") seat height

i think you can get as much as 300mm out of the adventure forks. the shock a maximum of 290mm.
But you better hope your over 6'2 for that sort of height.
"And some guy said, let there be filtering, and we filtered and we saw that it was good, and hours became minutes..."

I have the 05 640 Adv with the same front end as the 950/990 (48mm forks) and have lengthened the forks buy replacing the damper rod and the adjustment tube from the exc forks (48mm forks) . It takes it from 275mm to 300mm travel and in the rear shock you take out a spacer to increace the travel from 300mm to 330mm . It should be the same for the 990 it just depends on the length of the shaft to how much travel you will get.
