450's are a lot heavier, you don't really need a 450 unless your a big guy. There's plenty of power in the 250's. And you won't really get a foot on the ground on a 450

Get a yzf250 or a crf250, just a stocka, maybe get a good pipe on it in the future if need be. It makes a bit of a difference. You'll never get bored of it. You'll get bored of a 100 or 150 pretty quick, you'd probly have more fun on the 80.. I've got an 01 yzf426 and a 2010 fuel injected crf250 with a pro circuit pipe. The 250 is so comfortable to ride and the power is just perfect!! The 426 has an aftermarket pipe and a couple of little things done to the motor and it gets pretty bloody scary to ride. I'm only around 70kgs though haha.. I used to have a cr125 when I was younger and that was a lot of fun to ride. But I've found the 4 strokes are a lot more comfortable and just as powerful to ride. There a lot better for general trail riding and what not as well. Go a four stroke 250!!!

I've never owned a KTM but all my mates have had problems with there's, the two strokes any way, they often rattle apart like mad. Honda and yamaha is the way to go!

Even 12/52??

I bought it with 14/45 and it's a bit of struggle threw trails, hill climbs and any tight tracks really. Just gotta use a lot of clutch or just pump it up the hill climbs which gets a bit full on haha.. My little brothers crf250 revs out in 5th when I'm just going from 1st to 2nd. I was gonna go 13/52 if that would make a bit better for that sort of riding??
