ktm 250xcf vs 250xc valving differences

does anyone know or what the difference's in valving are on a 250 4 stroke vs a 250 2 stroke ( 08 ktm xc models)? im trying to get set up an ohlins ttx but only have specs for a 250 4 stroke and thought i could compare the stock valving settings to see what needed to be done for the 2 stroke. thanks.

on the forks 250/300XC and 250 XC-F have the same springs and the very same shim setup

like you need to go any faster greg:bonk: coppersmith's might be able to help out,especially if you bought it there;if not there is someone running a ttx on a 08 ktm that they setup i'll try an find the thread :thumbsup:

thanks man. if u find a thread on it let me know.

ktm-lew. do you know what the difference in valving is on the 250 sx vs 250 xc? surely there is a difference there since one is trageted for moto x and the other is offroad. thanks.

lew is saying the exc 4 and 2 stroke have the same valving, the sx will be much stiffer.

yeah the mx valving would be stiffer for sure. i would like know what the valving specs are on the sx.. compared to the xc. anyone know the specs?

Not sure where I found this but here is the 505 BV stack:

08 505 SXF

4-24x.1

1-16x.1

9-24x.1

1-22x.15

1-20x.15

1-18x.15

1-16x.15

1-14x.15

9.5x.3 clamp

16x.25 backer

anyone know the specs?

yes

at least for me it would be easier if you'd say, what exactly you are looking for.

TTX shock or TTX as fork cartridge?

First it was XC/XC-F now an SX as well, where there is a world of difference between those, SX is way, way stiffer

frezno, thanks for reading. after my first question was answered ( difference between 250 xc 250 xcf) i asked another ( difference between 250 xc 250 sx ). sorry if i confussed you. would you care to share the stock valving specs on the 250 sx forks? thanks.

I'm sure there are 2 different stack but ,in earlier forks, I found different spacers, different springs and different stack in the same bike.

so, the first thing I do in WP forks is check those things...

that base looks nasty stiff.....

yeah, all those new SX's are definitely too stiff for us average riders

imho it's more a pro setup for sandy conditions

ktm finally have decent fork hardware but hamper it with stiff valving?? its like they like to finish last in the shootouts?

thanks frenzo :ride:
