did you read what I wrote ?
In Quebec, you can't (anymore) have a licence plate (and so, the right to ride on road to catch another trail)for this kind of bike (aka bikes not sold as legal by manufacturer, and KTM didn't do before 2007).
Even if you put signals, mirror...
If you want a LC4, you have to buy a 2007 or earlier, or a 640LC4.
Mine ( I'll see and ride it in two week... while visiting family) was the first 400LC4 in the world... the proto... so, that mean "trouble could happen" and guess what, I only experimented one trouble.
A parts in the head, a kind of big washer (I don't know the US word for it) broke, and one valve felt not completly) in the engine.
Except
the valve, zero dommage was found after taking everythings aparts (and inspection by qualified mechanic).
The only special maintenance thing was flushing the oil (less than 2 Qts) and replace filter each 10 fuelling.
