Hi, I'd like to buy KTM RC 390 as my next bike and I'd like to ask some questions about it. 1.) What about durability of the bike? I'm driving a lot (Alomst 20.000km on 125cm3 in 1 year and 2 months) and I require from bike good durability. I have bought Yamaha YZF R-125 and paid almost half of...

So just got my RC390 this morning. I'm a new rider and have only putzed around with a buddies R6 for a few minutes. So when I say I was jacked to get this, I mean I could have wet myself with excitement. Onto to my problem. I drove it around the neighborhood after trailering in it home (100...
