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.

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?

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.
