GMP I thought I would throw in my 2 cents on the bike debate as I have recently rode my first Late model WR 250F. It was an 05 still with the cromoly frame. The bike was basically stock besides being uncorked ( CRD exhaust) grey wire and air box mods and minor suspension mods based on someone a bit lighter than me.This bike is Paul Neffs sisters bike.
Scott Neff, Paul's dad, also swears by the reliability of these small bore 4 stokes, and this is also his weapon of choice,although his is an 04 model. He also states the valves don't need adjustment all the time like other makes, they stay put. The bike was offered to me for a day, since my Gas Gas was torn apart down to the frame in Les's shop.They wanted to go out the next day after Paul's 6 days party, to Capitol Forest to do some trail clearing and riding. We had a real bad wind storm here and many trees went down.
So anyways, I must say I'm not a 4 stroke guy. Actually pretty much anti 4 stroke. Well this ride opened my eyes to how technology has improved the 4 stroke. Probably my biggest problem with 4 stroke motors is engine braking.I hate engine braking. This bike had virtually none. This was a very welcomed surprise! The motor had all kinds of torque power but being in the right gear was much more important than on my Ec 300, which is a lazy man's machine.The bike made me feel fast. I must have liked it cause at one point of the day Paul said to me " you ride that bike good" That made me really think, this coming from a 6 days gold medalists. He also let me ride his new YZ 450F stock, geared up with a fly wheel weight, but thats a whole other story.
If you rode the 250F in the higher rpm range it rewarded you, but still didn't tire you like some larger bores will do to you. A much more smooth delivery, which was very evident on the sloppy slick red clay of Capitol Forest.This bike felt light and flickable and went where you wanted it to.Handling wise, It felt about like my Gas Gas but didn't quite have the same ability on super tight turns like my Gas Gas, but what does! That could be due to the suspension set up of that particular WR.
The magic start button was pretty cool for the off and on sections where we had to remove trees. Fit felt comfortable for my 6 foot 200 pound frame.And even with the aftermarket exhaust, the exhaust note wasn't to loud. It passes NMA race sound tests here regularly.
After a full day of riding this bike I have a new appreciation for 4 strokes. The WR in particular. I would buy definitely buy one after talking with Scott about reliability issues, which he says as long as you do the regular oil changes and filter changes they are very, very reliable, unlike some of the horror stories we all hear about other brands of small bore 4 strokes.
I totally understand why your thinking about making the switch. I could race one of these and be very competitive on it in the woods and tight stuff. Which here in Washington is the majority of our races. Only about 5 out of 20 being super fast races in the desert or dry lake bed. I'm thinking about getting my wife a new bike. I'm sure it will probably be a WR. That will be a win win for me. I can ride the WR more, And test to see if my times are quicker on the small bore 4 and she gets a new bike and spoils me for a season! Good luck on your decision I hope what ever you chose is the right bike for you. Bikes these days are so darned expensive making the right choice is important. To have to turn around and sell it cause its just not the one, hurts the pocket book.
So there you have it my 2 cents. Later, Roscoe
