New KLR Squishymonster
Enjoy your KLR, I have an '09. There seems to be a good ADV representation in the Champaign area, should get a lot of support. KLR's are great and there is a ton of after-market farkles available.
If you want to learn good D/S skills, keep the 15t countershaft sprocket on it, it allows the bike to be ridden slower in the dirt with good torque. Ride the multiple gravel roads out in the country, it's not far away. Most KLR owners switch out to a 16t for increased speeds, me included, do it later.
The stock tires are ok in the dirt but you may need to drop the pressure if you're doing a lot of D/S stuff. Sand will kill a KLR, stock tires will not do. You will need more aggressive tires and honestly, they don't perform badly for all-around riding. My current tire trial is a Kenda270 on the back and a Shinko 244 on the front, works fine but took a little getting used to in the twisties.
