Welcome HI!
*I ride with 2 other people (seperate times) with KLR's that do very well. They blow me away going up the pass, but I blow them away on any single track or rocky hill climbing. My riding consists of maybe.....59%pavement, 40%dirt/gravel roads, 1% single track.
Just be truthfull with yourself on what kind of riding you will be doing. If you want to hang out all the time at the ORV parks...maybe the KLR isn't your bike. If you want to put some serious miles on, go further, explore, do some camping, and cost is a factor....go for it.
*There are riding gravel/dirt roads out there, just have to get to them. I haven't explored Granite Falls yet. Index/Jacks pass is on my list. North Bend is fun. Spada Lake is fun. The other places on my list consist of getting a trailer.
Get a bike, I'll show you a few places!!!!!
