    I'm sure this must be hiding in the merged thread, I just could not find it. Any rule of thumb on final drive gearing for this bike for various conditions. I admit I'm a novice at this but you got to start somewhere. Any big DON'T's ?

    The golden rule with the lc4, past and present, keep a 15T or higher. If you want more pickup 15/47or8. Three on back equals 1 on the front. Dropping to a 14 is tightening the angle to much.

    What's your thoughts on running a 14 x 48 set up? I've found that 15 x 45 makes it tough to crawl up rough single track without overpowering the rear.

    14 x 48. Keep away from the 14, lets say 15 x 51 I guess you could try it. She'd sure have some pickup.

    I'm using a 16-50 = 65 to 70mph @ 5000rpm and a 16-45 = 70 to 75mph at 5000rpm I use the 16-50 for hard dirt touring with the bike loaded for camping and the safari tank and for unloaded trailered to single track riding. I use the 16-45 for day rides with no load and the tank off in tight tracks I'm using alot of cutch but for the 2 lane tar it's a great gear set
    There's no one set up that will do it all :cry thank's to ktm's short sighted design... the stock 15-45 is the best do all
    Tryed a 14-50 set can you say wheelieee :evil the bike hits 55 mph at 5000rpm
    have fun

    I wasn't sure about the best place to post this question, either in the Wunderfest thread or revive an older gearing thread, so here goes; I just put on a 16 tooth countershaft sprocket on my 2013 690 enduro because of an upcoming trip with quite a bit of highway miles. The stock 15 tooth sprocket has the rubber "damping" pieces on both sides, and the KTM 16 tooth sprocket did not come with any and the ones from the stock one won't fit due to the diameter difference (the 16 tooth sprocket does have holes in it as if it could take similar rubber pieces).

    What is the rubber for, NVH reduction? Do I need to look for similar pieces for the 16 tooth sprocket?. For now I am going to run it without any, and I think many aftermarket sprockets are solid anyway so you could not mount rubber on them. Thanks in advance for any info.

    I went from 15/45 to 14/45 to test it and keep the same chain. For pure offroad, it is too high for me (Hatfield/McCoy). For the mix I normally do, it seems OK. I may go to 15/48 later if the rear will fit with the chain guide.

    Cheers,

    I absolutely love the 14/48 set up I'm running. Pulls hard everywhere, not jerky anywhere, fits my riding style perfectly :lurk

    The chain guide doesn't interfere with the 48 rear?

    Thanks,

    I use the following:

    14/45: trailriding
    15/45: general riding
    16/45: longer distance road rides.

    I do have a another set of wheels fitted with enduro tyres & mousses. The 16t front really helps with mileage, I only have the stock tank fitted at present.

    I think the rubber part is for noise reduction. Most replacement sprockets I get do not have it and no issues.

    I usually run the stock gearing which I guess is 15/45. I have tried 16/45 but that was too high for off road. 14/45 is too low for all the highway I have to do to get to the dirt. For 95% of the stuff I ride off road the stock gearing is OK, but I do not ride much single track.

    15 - 48 I run for greenlaning and even road work. I can cruise at 75mph and still do the Devon technical lanes.

    Just went for a quick test spin with the 16T countershaft - big difference, it should be pretty good on the highway, but it definitely lost some of the peppiness.

    Holy crap this thing can have some headshake at 75mph.....

    I've run 14/48 on the street many times, even a few 300 mile days of 70/30 on/offroad and the 690 never complained even at speeds above the posted limit. I don't notice any difference in fuel economy, it just buzzes a bit more on the highway. I currently have 16/48 on the bike (same as stock 15/45) and really never see the need to gear taller as I am limited by how fast my riding partners are comfortable cruising (te250, drz400, te630.)

    For strictly offroad use I would prefer a bit lower still and I think 14/50 will finally give the 690 a useful first gear in the tight stuff. I wouldn't want to cover any great distance with that gearing, but we do regularly truck our bikes to "the good stuff." I would have just run a 13 up front except that it forces the chain into the chain slider and would likely wear through in a day.
