looking to buy bigger bike.I looked at a 07 RM250 for 4000.But I don't know if 2 stoke is what i want.I got a cr125 right now which is fun but not enough gears.I'm turning 35 and feel that a 250 4 stroke might be the best for my old bones.What do you guys think of this bike?Is it a good deal,Idon't see any others arould here to compare.
