Heavier spring for 640 adventure?

I'm loading my 2003 640 adventure up for a trip trough Africa but wonder if it is wise to fit a stronger spring to the rear. It now has an 70-260 spring (meaning 70 kilo with 260 length).

I fitted the Touratech alu canisters (empty) and fixed a spare rear tire to the rear of the bike and already the bike drops way low to the ground.

I'm fitting a stronger one to mine, they are readily available from your local WP importer. I am upping the springs in the forks to.

What rates are you going with Buckster, and what do you weigh?

I weigh 215# (down from 240 and still dropping), and I just received a set of .48 for the front and 8.0/260 for the rear. Almost went with .50 on front, but several suspension gurus recommended against it. Hopefully I'll install them this weekend.

Stobie, any line on who has the .50's? If I can find those, I will order them for the 950 and move the OEM .48's from the 950 to the 640.

WP's stiffest spring is a 0.48, if you need anything stiffer you'll have to go with an aftermarket spring such as Eiback. Check out http://www.racetech.com/ for further infomation.

If you are going to Africa on your MC then we have no sympathy for you and your problems... where's the jealousy smiley?

Anyhow, have a great trip and please send postcards! You doing a prelim writeup or anything?

PS - the stock Adv setup is for a 165lb rider so anyone who is north of that and loading gear on should definately beef up the shock and forks.

Call Brad Lowe at Lowe's Racing: 989-288-6068. He has no website that I can find, and you might have to leave him a message for a callback, but he probably has what you want on the shelf. From what I understand, he stocks fork springs at least up to .52, and rear shock springs up to 11.0. The rear springs are actually for the PDS shock (but linear instead of progressive), so the ID is slightly larger (63mm v 59mm), but the length is the same, and fitment is no problem.

Also good news is that the fork springs are $80, and the rear spring is $80, include $10 shipping, and I'm respringing both ends for $170. I ordered them Thursday, got'em yesterday.

I think this is the first time I've quoted myself.

Anyway, 4mm makes a big difference. The 63mm ID of the PDS spring allows it to touch the shock reservoir. The options are to buy a WP, have Lowe's make a custom spring, or have a centering collar made that will center the spring.

Hey, Cugino Pegaso, you sell that 8.0/260 yet?

In weigh 200-205 and am going with a 80/250 which is right for my weight allowing for riding gear and giving space for winding in some more pre-load to allow for luggage.

Springs that fit the 640 Adventure

After reading through a lot of part lists and catalogues, I believe the following springs to be alternatives, all of which are 43mm x 485mm for WP 48mm forks, that will fit a 2003 - 2007 640 Adventure:

Part No. Description Original Application(s) Notes/exceptions
91410006S 4.4N/mm 640 Adv (2003 - 2004)

91410019S 4.6N/mm 640 Adv (2005 - 2007)
990R Adv (2007 - 2010)

91410020S 4.8N/mm 990R Adv (2007 - 2010)
950 Adv (2003 - 2004)

91410021S 5.0N/mm 690R (2009 - 2011)
990R Adv (2007 - 2010)
950S Adv (2003 - 2004)

91410010S 5.2N/mm 690R (2009 - 2011)

91410065S 5.4N/mm 690R (2009 - 2011) 465mm length

I'm sure there are others and it would be useful if we could keep a list of substitutions people have used with success and others we've had trouble with.
