It's an expensive, high performance bike, so I've got no problem using the oil that KTM recommends. It's a little cheaper if you get it in the four-litre jug. I order the jugs through my dealer and the price works out to $15.75 per litre.
Have you priced out any synthetic, automotive 10W-60 oils? I'm sure they're expensive too, but even if you could save ten bucks a litre, why risk it? The crankcase only holds 1.7 litres, and the oil change interval is 5,000 kms, so your savings would probably amount to twenty bucks a year.
Kind of reminds me of those threads where someone buys a BMW, then asks if they really
need to put premium gas in it.
