Wow Matt, you really are a Steely-Eyed Motojourno! I'll have to get you to autograph my gas tank when you visit FL this Fall.

Guess you were right in all those rants on the 4 stroke dirt bikes:

maintenance will come sooner than with the previous design. I’d say 16-18 hours

Sheese, is that...ok???

C'mon, Matt. Now that you're a published motojournalist, let's keep an eye on the facts. Yamaha says the wet weight for an aluminum-framed new YZ250 is said to be 229 lbs wet. YZ450F: 238 lbs. Also, I don't think any stock 250cc 2-stroke made over 50 hp.

Well, a 2000 CR250 Honda put out 45 horsepower, stock. Not too shabby. Wet weight was 223 lbs stock. A little porting, a new pipe, carb and 50 hp was no sweat. Add an aluminum sidewinder sprocket set, some ti bits here and there, 210 lbs. was easy to achieve.

And a 2008 YZ250 put out 47 hp. Last I checked Yamaha has quit making a two stroke 125 and 250 for 2010. Too bad.

Thanks for keeping me honest there KD...

Lucky for 2-smoke fans, KTM is still keeping the hazy dream alive!

Good write-up, Matt. I guess the days of restoring a 10 year bike for trail riding are long gone.

That being said, I couldn't be happier with my KTM525EXC.

Yeah my regular dirt riding buddy went from a KX500 to a KTM EXC525, loves it. Fast bike too. When he was in the groove I couldn't keep him in sight. We got on El Mirage dry lake, for a drag race. I had a GPS in my pocket, I pulled the KTM by about 20 bike lengths. The GPS said I was doing 97 MPH. His 525 topped out at 92 mph. Maybe gearing or something, as I though for sure the 525 would have my CR on top, but no.

Nice bike. However I think the four strokes have come along way. The 2strokes will be dearly missed. Hopefully Yamaha will continue producing their 250. But I doubt it.

2009 was the last year for the yz125 & 250 two stroke models from Yamaha. The end of an era.

I'm sure 2 strokes will be back in a cleaner form, with sealed 4 stroke type lower ends, and no pre-mix for the green crowd. They make too much power, and are too reliable to go away completley.

Also that's why the vintage/classic/bomber classes have taken off lately. And why I got $1,200.00 for a 22 year old CR500.

Shoot, I sold my old '97 CR500 for $1700.

Then turned around and bought a pristine 2001 CR500 for $2500. Worth every penny!

I know in 2006 we could still order Cr5's or Kx500 new. Figured Yamaha wouldnt make the 2strokes anymore after this year, but I can dream.
