Just want some input from you all on what I can expect power wise from each. I really am a bit hesitant to go with a 450 due to the power. I dont want a bike that will be unpredictable on tight single track trails. Ive ridden motorcycles all my life, but only been dirt bike/trail riding for about a year now. I am currently on a WR250R that has been modded to off road only, basically the EFI version of the F model. I know the WR250F will still have more power than my R, as well as better suspension. So should I consider the 250F or go ahead and step up to a 450F. Who here has both bikes and can compare the two for me? Thanks. BTW...Im 6'3" Tall and 215lbs with gear.
