No not on a 2 stroke 250SX, however the 4 stroke 250 SXF does.

A single cylinder 2 stroke 249cc engine with a Keihin PWK36 carb.
The engine that is supplied stoke standard with every 2013 KTM 250 SX sold is a 2-stroke engine which is really reliable to use. These are fitted to many motor bikes now days.
40:1, I run Maxima 2-stroke oil and that works awesome
If its a two stroke then it just needs some 2 cycle engine oil
You can but it is not very good for the bike, its defiantly better if you put a motorbike two stroke oil in it as KTM's don't like other types of oil cheers
it was a 4 stroke
the ratio is 50:1 on my ktm 125sx, for every gallon of gas you have, you need to use 2.56 oz of oil. i use Amsoil, its expensive, but its the best synthetic two stroke racing oil there is. the gas should be light pink if you mixed it correctly. hope this helps
yes sir it is
KTM recommends Motorex Top Speed 4T 15W50 - 0.7 L It is a 2 stroke motor however. So I run the 80W-85W Honda Red, or typical 2 stroke oil such as Maxima, BelRay 80W or 85W I abuse my motor at tracks and may need the extra weighted oils for extra safety
