I prefer the Shinko 244 to the Kenda 270 on the rear. Take a look at the outermost row of lugs...on the Kenda they're small, on the Shinko they're much more "blocky" and substantial. The Kenda was fine...fine...fine...oh SH*T as you leaned over on pavement. That outer row of lugs is wiggly and scary when you get to it. The Shinko outer row feels like the rest of the tire, no surprises. The Kenda 270 comes in a 3.25x21 whereas pretty much all other decent tires with that kind of tread pattern are only 3.00x21. So, I prefer a Kenda 270 3.25 F, Shinko 5.10 244 rear. By the way, if you're considering a 4.60 for your GFs bike, be aware that the smaller overall diameter of the 4.60 will act pretty much like dropping one countershaft sprocket tooth (which can be helpful or disappointing depending on what you're looking to do). The K270 3.25 w/ 244 5.10 R is my "go to" setup for my '08 KLR650 whenever I want a "I'm not sure what I'm gonna get into, better set up for about anything" tire combo. For my experience with other tires: 1) I currently have Shinko 705s on both ends and they work pretty well for pavement and gravel roads and such. Haven't had them out too much in the dirt (put them on later last fall and I'm in Michigan, so deep into winter right now), but imagine they're not gonna be all that good. But again, for what I've been riding lately (pavement and gravel roads) they're fine. Surprisingly good traction on dirt roads and very nice pavement manners as well. 2) Had D606s on the KLR and they truly are the best full-on offroad tires I've had on it. Noticeably better offroad performance than the K270/S244 combo, but of course you'd expect that of a full knobby. Front in particular felt really well planted. 3) Cheng Shin 858s both ends weren't bad either, but they wore a little too quickly for my taste. But then they're very cheap to buy, so if you like fresh tires often they might be the right choice.
