Progressive fork springs?
-
Until I know for definite that the 2004>RE has 505mm springs I can’t be sure about them...
Early Dtr’s had shorter springs than the later ones, apparently...
-
@SpookDog But springs compress...
Can you not just email then and ask?
I remember the DTR springs are woeful, so this would most likely be an upgrade.
-
I actually didn’t think to contact them 🥴
Waiting on a fleabay reply now. I asked about length & width and rating...
@SpookDog According to Haynes:
3DB1 ('88 round slide carb model) spring free length 478mm, service limit 473mm
3RN1 ('89 onward) spring free length 503mm, service limit 468mm
No mention of forks in the separate chapter for the '97 onwards DTR and DTX so I can only assume the springs are identical to 3RN1 (although I'd be interested if this is the case particularly regarding the DTX)

@SpookDog And according to fowlers the springs between the two models are the same.

@HOTSHOT-III I believe the DTX has shorter stiffer forks.

@HOTSHOT-III
That’s a typo for the 503mm spring wear limit, it’s supposed to be 499mm. Hell of a wear limit otherwise!.
I read somewhere that dtx springs are 515mm and progressive as standard. Probably the same as TZR springs if the info was right...Got a reply from fleabay: not in UK stock, 40-45 day order wait. Springs are 515mm x 3.9mm and are rated for 65-110kg weight riders...
Sounds perfect, just have to trim the spring spacers by 12mm. Shame about the wait!...

Cheers for the info guys, it all helps!...
Ordered some springs, just in it for the long wait now
If anyone has any fork bottoms, or whole forks, please let me know. I don’t have time to powder coat mine when I rebuild them...
-
Did you just delete the spacers completely? Any noticeable improvement? Also are the springs linear or progressive?...
Cheers bud!...@SpookDog said in Progressive fork springs?:

Cheers bud!...Didn't remove anything as memory serves.I had 2 forks,one DT125 and later one DT200,I had purchased every part to rebuild the 125 before having the 200.Compared everything and found to be the same except the springs.So I used the springs and the air adjust caps from the 200 forks.
They don't bottom easy as far I tested them and seem better for the SM style than the 125 springs,but soft to go trail ride.
