I noticed this leak a few weeks ago before i went on a ride, I noticed I was low on oil. The bike at that point only had 2650 miles on it. Last oil change was at 500. So I canceled my. A week later I cleaned everything coated in oil and even the front sprocket area to rule that out. I changed the oil and put a new filter on it. Made sure there were no signs of oil residue and took it for a short 25 -30 mile ride around town. Got back and no signs of oil. Today I took it out for about 75 miles and when I got back noticed the leak was back. Below are pics the best I could get. I can't really tell where the sign of the leak is but there are some places where more is noticeable then others. I know it is not a result of chain oil. I have to say I am very frustrated by this at now a little over 2700 miles on the bike. Anyone else see this so early on a 2012 T100, or have ideas where it is originating from.

Very nice pictures, you have a good camera there. However, the exact location of this leak is a bit ambiguous. Is that the primary cover or the triangular timing cover? Either way, if the dealership isn't too far away, I'd take it there for some warranty work. Since about 1972, new Triumphs aint supposed to leak. Period.

Taken with an iphone.

Here is a parts schematic from Bike Bandit. Cover 21 seems to be where it is centered around, but it is hard to really tell.

Also check the countershaft o-ring (front sprocket), I had mines replaced not too long ago and it dripped around that same area too. Either way should be an easy fix!

i bet its the seal behind the front sprocket .It will fool you .What you need to do is take sprocket cover off clean around Tthe shaft seal real good ,ride the bike get it good and hot.put bike on side stand let it idle and watch shaft seal.Cut it off and watch for oil allso.What hapens about 80% of the time the oil runs out of seal then runs down the shifter cover and you cant see that the seal is leaking.I found this out the hard way lol.

I'm looking behind the front sprocket as I type this and think that may be the problem. How hard of a fix is this. Or how hard is it to get to the o ring?

Well I cleaned everything up and took for a 40 mile trip and it does appear to be weeping from behind the front sprocket and riding the gear box gasket do to underneath the bike. So judging from some searches this is pretty common?

Common fault sometimes caused by filling the engine oil above the top level line....easy job with the seal just pull theold one and drift the new one in with the old seal...
There are plenty of threads on this...

Anyone have any instructions on doing this. I should have the dealer do it but coming into winter and them being a good 45 minutes away, I may do it myself if it is easy enough. It doesn't lose a lot of oil, but I don't want to have to keep worrying about it especially when the bike is this new.
Even if I have them do it, I would really be interested in knowing how to do it myself. I used to tear into my harleys all the time, but for some reason I am timid to do anything to involved just yet on this bike. Probably the newness factor.

it is an easy repair but...
you paid BIG $$$ for a new bike with warranty.
make them earn some of that $$ you spent !!!
