Im looking to move up full time after this season form a kx 100. Im debating what i should get a 2 stroke or four. I can fit the big bikes easy enough to kick a 2 stroke but never even rode a 250f. I want the repair bills to be cheaper so im thinking 2 stroke but dont want to sink big bucks into aftermarket parts so there im thinking 4 stroke. Ive owned a cr 125 but never really rode the bike because of head shake. I loved this guys Husky 144 and it was real easy to ride but he sunk alot of money into the motor. So im really torn over this and my dad told me he will get me a 2010 kx 125 or 250f. Tell me what you think i dont know if it helps but i have 11 years riding and 10 years racing and id like to say im fast. Im both bike. (PS: I allready asked the guy to sell me his 144)
