nouveau suspension arrière - new rear suspension

[macbig2k1]

Salut,

a TW-driver (he lives in Israel) from the US-TW200 forum had a very good idea for a new and better suspension. He installed a Yamaha R1/R6 suspension.
The big positive from this suspension: Complete adjustable!!!
And the R1 suspension does have a bigger stroke (TW -> 48mm; R1 -> 65mm).

I adapted this idea for my Cross TW and Supermotard TW.


At first, the comparetion between all rear suspensions:
-> org. suspension
length: 330mm
-> org. suspension with 35mm tailraiser (important for Cross TW)
length: 365mm (absolut max. for TW)
-> R1 (and R6) suspension
length: 300mm




To have a correct seat hight with the new suspension is a good tailraiser with a fitting length very important.
for same hight like org. suspension:
R1 + 25mm = 5mm shorter as org. suspension (325mm)
R1 + 30mm = same length like org. suspension (330mm)
R1 + 35mm = 5mm longer as org. suspension (335mm)
for high raised tail:
R1 + 55mm = 25mm longer as org. suspension (355mm)
R1 + 60mm = 30mm longer as org. suspension (360mm)
R1 + 65mm = 35mm longer as org. suspension (365mm)




You can see here the ground clearance from my Supermotard TW with the small (and low) 150/70-14.




Now the steps for the installation:

Step 1
- Mount the raiser - the top holes must fit correctly
- bore some sec. with a 10mm drill in the lower hole, to make a mark




Step 2
- bore a hole with a 4...6mm drill in the marked position
- bore this hole up to 10mm




Step 3
- remove the bushing/sleeve from the org. suspension and insert it in the new suspension
or
- make a new bushing/sleeve with this measurements:
outer diameter: 17mm
inner diameter: 12mm
length: 40mm




Step 4
- the installation




The result with the 55mm raiser; grund clearance +~5cm




Here is a pic to compare the org. suspension with the R1 suspension with 3 differend raisers (55, 60 and 65mm)




The raisers (25, 30 and 35mm) can be used too for the org. suspension

This info is awsome.
If i have "stoping problems" with my suspension on big jump i know who to solve it.
Great job and great procedure buddy.

Send me a eMail, if you need a set.
But you have to tell me the the length from the tailraiser and for witch suspension the kit should be.

I don't need yet, but may be later.
Thanks

Yes too!!
Sa peut etre vraiment bon vu que notre TW est vachement plus legere que une r1 on aura un putain de bonne suspension ! Et rigide !
What version do you use ? 1999 ? 2004 ? or we don't care ?

[macbig2k1]

The R1 and R6 does have 2 different rear shocks.


Version 1 (I use this version)



R1 (RN01, RN04, RN09)
1998, 1999, 2000, 2001, 2002, 2003

R6 (RJ09)
2003, 2004, 2005


Version 2




Version 2 fits too, but you have to make a small modification on your airbox.
Here are to links (from "Yamaha TW200 Trailway Discussion Forum") about this mod:
Has anyone ever upgraded the TW's rear shock??(R6 shock upgrade swingarm and airbox mod!!)
R6 or R1 Shock on a TW

Hm....strange, the links to the pictures were not correct. I have changed the links.

comment avoir les cotes pour en faire des identiques ?
ou bien où les acheter ?

where to buy this item?
or how to create them?

En parlant d amorto arrière . Il y eu une campagne de rappel. Comment savoir si une machine en a bénéficier. Je me ferai bien changer l amorto gratuitement par yam si ca n'a paoint été fait.

[Castor]

Soit par MP à "Macbig2K1"
Soit sur son site TW-Parts.com (formulaire...)

Merci pour l'info !

C'est vrai que je n'ai jamais fait attention à ton amortisseur, honte à moi 
Le nouveau, en partie basse (sur le bras) l'axe fait partie du corps de l'amortisseur (pièce moulée), sur l'ancien c'est un tube soudé sur le corps.

Je me ferai bien changer l amorto gratuitement par yam si ca n'a paoint été fait.

Heuhhhh, pour toi, ça risque de ne pas être gratuit 
Avec toutes les ferrailles qui tiennent le réservoir qu'il faut démonter avant d'atteindre l'amortisseur, tu risques d'avoir un supplément 

[Namna]

Tu regardes la finition de la fixation de ton amortisseur

Et voilà, une belle photo vaut mieux qu'un long discours ...
Merci Christddel

[chrisbdc]

Un grand merci Christian je vais regarder cela demain et le cas échéant voir Yam/
