There are no stupid questions, only stupid people
I can't speak for the 500 efi, but my 450 carby was not super easy to work on. That said, I attempted a valve check on a friends exc 250. What an utter pig to work on. Even after you dis assemble the entire bike to get to the head, it's a total PITA to check the actual valve gap. It took me less time to rebuild my two stroke, than to check the valves on the four stroke.snakebitten said:"not streetable" is one of those terms that aren't really literal. Of course it is literally streetable. It is licensed no differently than a Goldwing.
And actually, the 500exc is now into its 4th or 5th year and is proving to be FAR more reliable than many predicted.
One chap just arrived in Oregon from the bottom of South America. I believe he just hit 500 hours! (He's from New Zealand and has a pretty cool ride-report. New Zealand to Oregon)
I have one myself. It's an outrageously fun bike to ride and very easy to work on, so maintenance isn't a drag. But I'm not fond of the idea of long highway runs on it.
It's a serious dirt bike with a license plate. Skinny, extreeeeemly light, tall. But I have no reservations for jumping on it and ripping a commute, just to charge the battery!
Fair warning though, asphalt will consume the kind of tires that this bike deserves to be shod with. And if you choose to motard one, it'd be wise to put a cush drive rear hub on it.
My Yamaha dealer just picked up Husqvarna. Those new white (orange) bikes look gorgeous on the floor next to the blue-yamis.
That said apparently all newer ktms rarely need valves adjusted. If it starts easily when it's hot, then you're good to go.
I can easily see hitting 500 easy hours (Read: dual purpose, not hard trail riding) and not needing a new top end.
People also freak out about two strokes needing work all the time. My second hand 300 had close to 150 hours when I bought it. I put another 140 hrs on it before pulling the cylinder. The jug needed a light hone. The plating was spotless. After putting a new piston, pin, rings, and gaskets, it's good for another 250 hrs.
The biggest plus about the 2 stroke is maintenance. Change the transmission oil every 10 hrs. Check the air filter, clean when dirty. Ride the piss out of it. My next bike will be a BETA 300rr injection. A bit softer than the xc/husqavarna te, but more suited to the riding I do. Plus oil injection means no more premix. The guys I ride with that own them love them. Great bike for the average guy.
Bikes have come a long way.
