lots of good ones,few really, really bad ones-people are getting scared and getting rid of them.the 2016's seem to be much better.there is an aftermarket fix if the head gasket goes that seems to work.mine is used for track mainly-i did the suspension,brakes,did some preventative stuff to make it run cooler, and had it tuned.handles better than any bike iv'e ever had and is a lot of fun on the track.on the track its a slow bike that handles great,and is a lot of work because of relatively narrow powerband,you have to shift a lot,it seems like the gearing is always wrong.on the street it's not just one of the faster bikes of the class,it's legit kind of fast.tank is odd shaped and hard to move around on the bike,stock riding position is all day comfortable.seat looks like a plank,but works for me.i did a couple of 300 mile days breaking it in and felt pretty good.bike is light!!-even for the street you will need a rear shock-with a good rear shock front feels much better,but i did andreanis because of track duty.a galfer 320mm rotor and pads improve the braking.finish is pretty rough.fairings split at bolts and paint is coming off foot controls.both are being handled by dealer.i put in engine ice,a better radiator cap,pcv and had it dynoed and it runs much cooler.you have to watch out for fan failure and there is a upgraded spal fan that works well.usual ktm pita maintenance,but for the performance it's worth it.besides the cosmetic stuff i have had no issues with this bike-if i had only one bike would this be it-hell no!!if you are into small bikes and want some performance,this is pretty much it.with a airbox mod,k&n,pcv and stock pipe i'm getting almost 43 hp at the rear wheel.if you like riding twisty backroads you end up going effortlessly faster than usual.i guess to wrap it up,bike is a blast,but iv'e always got one eye glued to the temp guage,and i'm always listening for the fan to come on.

oh yeah,forgot-lots of vibes down low- smooths out very nicely over 4-5000 rpm.also-doesn't have a slipper clutch,but sure feels like it.
