Thanks for the news flash KTM033!;)
Any of todays 4strokes would work, there will be those that say it is a motox bike only and others will tell you to run it in the woods if you like! As far as the comment regarding one boiling over after idling for 5minutes..jeez, so would every other water cooled 4stroke on the market. My 426 will get warm in tight, tight stuff but won't boil over. Run the coolant about an inch below the cap and ride. If you like the bike enought to buy it, transform it into whatever makes you happy.
