2014 timbersled sx on ktm 250 sx what sprocket size
- Thread starter Pedec
- Start date
I run the 12 tooth on mine and run the chain as tight as I can with the bike on a stand (no weight on track). The chain will be a tight fit to get hooked up, I even have to lift the back of the skid up a bit to connect it.
I ran the 12 tooth and adjusted the track run out with the chaincase gearing. Skip the half links you can get what you want without one.

14-18. 12-17 is too low
Agreed that 12t is way to low. I run 13-17 17-19 on 300, and will be trying to run taller this year.
I had an issue with this on my KX500. I had to find a smaller bolt! I ended up cutting a few threads out of a 5/8 - 16 x 1 1/4 I believe.
I also moved the mounting place of the bolt by drilling two holes about a 1/2in towards the rear of where its set from the factory. Just two allens holding that bolt there on my kit.

Ok so tried running 13-16 and chain was to tight. Only thing I find that works is 14-16 with half link. Is it safe to run half link. 14-17 16-16 should be great gearing and have enough chain slack for sx movement (not to tight) and chain is not hitting track. Timbersled really needs to improve this chain tension set up really sad for what a guys pays for kit. Gearing is very important
I have ran half links without problems. Both in case and drive chain. 2 stokes are easier on chains, both in the dirt and snow. Another thing to think about is going away from oring chain to free things up. They move way easier and don't rob as much power. I like the 14/17 idea. Tillbuilt has a 17T keyed sprocket for sale if you don't have one. Or take a 17 out of the case and swap it with the 16 on the jackshaft. Then you could go 16/17 if you want to be a little lower geared or 17/16 for more topspeed. Let us know how it works out.
Off topic, But did you remove your airbox completely or just cut clearance for sx linkage?
On my SX120 I am running 13/16 - 18/16. On a KX500. Works awesome!
Having troubles getting SX120 kit to fit ktm300 XC
Having a heckuva time installing my sx kit on ktm 300xc bike, have tried 13/16 and 13/17 and chain still too sloppy. half link or different chain needed? Do you know if the TSS shocks are identical OR are they bike-specific? I ask because we are running TSS but it was installed on a Yamaha last year, wondering if the TSS being "off" so far (2.5" shorter than what we needed to make it fit this ktm) is what is throwing our chain/sprocket setup off?? Any help is appreciated, thanks.

He is running a newer version SX if using TSS. Go 14T! The 250/300 has always taken weird chain lengths when used with mtn horse. That's why they say to use the 12T CS, which we all know is ridiculously low with high rolling resistance and chain wear characteristics.
