I guess I'm gonna have to take to working out and weight loss. Seems the newer dirt toys are too good to keep over-looking.

Ok,.. you know the first person over at Yamaha was drunk when they thought this up, right. Cant wait to ride it,...

Now I'm all in with the "form follows function" dictum in design, but that is one goofy looking dirtbike.

I'd much rather have a '73 400 CZ (blue coffin tank). Not only did it haul ass, it did it without looking like a thalilomide expresso machine.

Just another nail in the box. How many hours on the motor before this one grenades?

Feh Fie and Pox.

I think it's cool, and it looks cool, IMO. At least it's not another copy-cat design in a different color.

So..........was Cannondale right all along? :D

Well, after years of development, huge expense and all that we have a 450 that might almost be as good as a 250 2-popper.... at least until it throws a rod, eggs the lower end bearing seats or sucks a valve. Or all three. At once.

40 hours between $2000 rebuilds?

You guys ridden a modern 450?

Unless you're Bubba or RC, you're not beating one on a 250 2 stroke.

Just about eveyone rides 4 strokes these days. They're not that bad, and they don't blow up all that often. That's the 450s anyway.

The 250s blow up a lot more often.

I've been riding my 520 EXC for 5 years now, with no wear or maintenance issues. I check the valves every year, and it only needed adjustment once. Changing the oil is a bit more painful than a 2 stoke, but I can live with it.

Try one, you'll like it.

BTW, I also have a couple of 2 strokes in the garage to keep me honest.

I've got both in my garage as well. But your KTM is not one of these works-type wunderbikes. From the riders I know and the feedback I've seen on the dirt blogs I wouldn't touch any of the fancy shmancy works-type MXers with YOUR 10 foot pole. Naw, I'll stick with the DR400 style powerplants and give up a few HP for a lot more durability.

Beat me to it. Cannondale was before their time apparently. Love my Cannondale Mountain bike.
