    I don't think there is a thread on this yet, or at least I don't remember one. Inmates like Alex at Konflict and Cory at Camel ADV are using these bikes pretty hard, along with a few others, and I hope they can chime in. Stock gearing is pretty tall but really just about perfect for typical big trailie work, but for slow, tight riding it feels to me that a jump to a larger rear sprocket is needed. Maybe only three teeth? I have not yet consulted Gearing Commander it will do so. Anyone have any experience yet?

    I haven't taken mine on anything but dirt roads yet, but, yeah I think 1st is tall (I'm on a non-DCT). Funny, but folks always said that the Tiger 800XC has a tall first gear and I elected to put a slightly taller corset on mine and I'd say it was still shorter than the AT. My only real complaint about the bike.

    I dropped the front down to a 15T and it's perfect for everything.

    Here, but lost. Am I lost if i know i'm here?

    I might be the one weirdo who thinks that this bike isn't intended for slow, tight, technical stuff. But that's just me.

    It's a great bike for what it is.

    A separate thread isn't required IMO.
    -1 down in the front is like +3 in the rear.
    Helps get the acceleration back lost here @ altitude in Colorado.
    It won't pull redline in top anyhow with the stock gearing, might as well make it useful.
    Better in the slower knar picking better lines. My two cents.

    +2T on the rear works fine with the stock chain. My speedo is approx. 6% optimistic.

    Just dropped the front to 15T and am anxious to ride it and see the difference. There were a few times last year in rough rocky tight spots that I wished for a little lower gearing.

    Will see how it goes and will be following the members input on this.

    You can't really redline 6th so dropping to a 15t might be the ticket. Stock gearing seems to work well in most conditions, I'm not skilled enough to ride slow technical sections on the AT where I can ride on the dirt bike.

    First is tall and I'm intending to drop it down on my manual. Once fully loaded you need good clutch management to get moving in an off road situation. I find my older version Africa Twin (XRV750) is easier to get going in these situations. There's also a small flat spot in throttle response on my CRF around 1/5th-1/4 throttle which doesn't help. Still a great bike and nothing a bit of tweaking can't fix.

    I don't go looking for slow difficult sections when on the AT, but especially here in rocky Arizona, you never know when a reasonably good old mining road will turn difficult for a short distance. Rocks larger than normal, steps and ledges, seem to pop up out of nowhere, and slowing down with clutch out is really beneficial. I prefer to go up on the rear rather than down on the front to take it easy on the chain. A new chain will be needed, but I think that up three on the back is in the cards, soon. Going to do the Heart of the West again, this time on the Africa Twin. That route good for big bikes and will be a perfect test for the new gearing.

    I rode one for the first time today. My impression was also that 1st gear could be a bit lower, and I really doubt it would hurt highway performance. I had the same feeling on the Tiger. My Wee might benefit as well, but a bit easier off the line. Nice bike though. I really liked it. Haven't been on the DCT one yet.

    I order a 44T rear yesterday for my DCT. I'll give it a try see how it goes. Will definitely help on steep off road sections and I rarely go over 140kph on the tarmac so don't expect to feel it at the other end too much.

    I rode a 15 tooth front sprocket for a few weeks but ended up going back to stock. To me the bike feels happiest running the gearing that Honda intended. There was a little extra torque at the low end but the speedo became really inaccurate and cruising wasn't as relaxed. I've since fitted a more free flowing exhaust which gives improved torque at lower revs. Between this and better clutch modulation, 1st gear crawling is great for me now.

    I ride some pretty rough stuff in SA and Lesotho.. I find that the best approach with the big bike is to look ahead and hit things at pace... trust the suspension (that you've spent hours working on) to soak up the hits... momentum is your best friend with the bigger bikes, so the stock gearing is great on the AT..

    They (Honda Service) does not recommend changing gearing on the DCT . . . It may confuse the computer . . .

    Hopefully, it will not cause any issues . . . since bigger knobby tires are similar to higher gearing . . .

    Interesting, I had not thought about that. Good point on buying that bike.

    A thought on the smaller primary sprocket. If you have DCT why would you need lower gears? Wouldn't the "automatic" and slippage of that take care of you where you might want lower gears with the MT?

    For what it's worth I went 15 / 44 on a DCT. The bike will no longer shift under throttle at high RPM in 3rd, 4th, 5th, 6th You can throttle back and change up or down like a normal bike but auto wont work. Manual only and coming off the throttle to shift. Annoying as the bike felt great at low speed off road. Will take the 44t rear off, leaving the 15t front and see if it works again. If not i'll put it back to stock.
