Hey everyone this is my first post, although I've been reading over the past couple of days for hours on end (mainly the CRF250L thread). I haven't found the exact answer I've been looking for though. I am very likely going to buy a 2013 CRF250L from a local dealer on Friday. My question is: How capable is this bike at maintaining highway speeds (68-70mph) at a very comfortable rpm range for an hour or so at a time, without the bike seeming like its really struggling to keep up. A little information about me: I'm about 5'11" 170lb, will be riding mainly on pavement, using this bike as a commuter, and occasionally going on pretty tame dirt roads, nothing too crazy what so ever. If there are any changes I could make to the bike to help it out on the pavement I'll likely make those changes. Planned changes: Some type of luggage rack 80 street / 20 trail tires (maybe something along the lines of Shinko 705) Maybe drill the airbox Some Handguards Change sprockets to get the optimal gearing for my use (I dont mind to lose some low end power to gain some top end speed) I really hope to not have to change the exhaust to get the changes I want but might later down the road if I must Thank you all in advance for taking the time to read and reply to my post. Have fun riding this summer, I cant wait for the weather to break here in southern Ohio for some warm weather riding.
