Wardy need your opinion or anyone else?

every "good" should be a "well". hope your career as an MX'er takes because with communication skills like that you need all the help you can get:p Ride the 4stoke and find out the difference for yourself. If you feel more comfortable on it then race it, if not ditch it.

I would ride

the 250F as much as someone will let you to see if its the bike you wish to ride. In this sport the bike is much less the reason a rider does well (good ;) ).
The racing skills you develop at this stage in your racing will be with you a long time, it mite be better to practice and become as good of a rider as you can, with what ever the bike you ride. Do not worry so much on which bike that is.
Not to mention i think there will be new rules pertaining to some of these bikes in the future. Have to wait and see on that subject.

hey, the boss is right. If you think about it, you might be better off with the 125 in the long run, even though i personally own a 250F. Here's why: since the 125 has such a narrow power band, (and the bike pretty much sucks when it isn't in the 'zone') you are forced to make accurate gear changes and you must develop excellent clutch control in order to be competitive. Since the 250F has the torque, you don't have to be quite so precise.
A truly excellent rider will have developed outstanding clutch control, and this is so important in all aspects of dirtbike riding, regardless of bike type. A MX rider will use the clutch to keep the engine in the 'power band' for maximum accelleration out of corners, while the enduro rider will use his/her clutch to progressively feed power to the back wheel during slippery hill climbs. Using the clutch to control wheel spin is much better than using the throttle, as it keeps the engine in the 'sweet spot'. This is what a 125 MXer will teach.
I have always thought that under some conditions, a powerful bike is a really good substitute for skill (especially something so smooth and easy to ride, like a KTM400/520.) A rider on a 520 can afford to be sloppy around corners, as all they need to do is hold it wide open when the road opens up, and reel in all the small bikes. To keep up with a 520 on your 125, you MUST have a text book riding technique, as corner speed is so important. On the straights, everyone has the gas fully open, so where are you going to make ground? I am assuming you see my point by now. By all means buy a 250F if that is what you want, but im not sure if it is what you need. The extra money you will spend on the 250F will be much better spent on professional riding courses, as this will benifit you for the rest of your riding life (if you take in the infromation. If not, then its a total waste of money).
Oh, and to finnish, there is no better feeling than beating a bigger bike around a track, and if you don't, well you always have the 'ah, it's only a 125...' excuse! (just kidding, no excuses on lack of displacement here)

They are right! If the 250f was that much better, all the pros would have one. You just need to change your gearing on yours. Go to a 50 /51 rear tooth on your yz it makes third gear more useable and second a bit more on the torque side.

actually, i do think that the 250F is that much better. It is a real surprise packet, and no other 250 four stroke comes even close to it, and the 125's aren't that much closer again.
The point i wanted to make was that we should be looking at ourselves as the weak link in our riding package. We all have such huge potential to succeed in any area that we chose to follow, but sadly most are too lazy to try. No Fear put it well in one of their slogans : you will never know if you have what it takes until you have given it everything you've got..... how many people who have failed (such a hard word) in a particular field stand up and say, 'i gave it everything i've got'. I reckon not too many, and those that can probaly don't know what everything they have is.
If Troy didn't have a bike and wanted to race in the 125's, then i would suggest he should buy a 250F. Things are heading towards 4 strokes in all classes, so expect to see big changes in the near future. But, since Troy already has a tricked 125, i don't see any reason to move to the 250F, and my last post explains the reasons why, and why he may even be better off on the 125.
Make no mistake, the 250F is a big step forward in four stroke technology, and a few years ago anyone would be ridiculed for even suggesting a 250 4 stroke MX could be built, let alone successfully. The next few years will be very interesting and exciting for all dirtbike riders, as the manufactures compete to dominate the small and big bore classes. Yamaha brought out the class winning YZF400/426, which was then matched by Hondas CRF450. Suzuki have a RMF on the cards, and Yamaha is soon to release a YZF450. The 250F threw in another variable for which the Euros have hit on quickly. Expect to see 250F's from KTM, Gas Gas, TM and Husky. The rest of the japanese manufactures will naturally release their own versions. Im sitting and waiting.......

was just picking yith ya. But i'll be your personal editor if you wish:)
didn't mean to seem snappy, I really was just poking fun. I should have worded it differently, But I've had a problem with a member here, and have been a little quick with the wording. Good luck on whatever ride you chose, just remember, the more intelligently you present yourself the further you will go in life, and the better you will represent our sport. again didn't plan to offend.

Try starting that thing. It will take a lot of getting used to after a yz125. The 426 is even easier. A lot is two words.

Troy_776
can you ride one for any legnth of time to see if it suits your riding style better? That's what it really boils down to. Does the bike match your style of riding?
About the starting thing-
This past weekend a new track sort of opened ( a free day to get feedback, it will open offically in the spring). There was a guy on a 250f who was very fast. There was a pseudo race. He came in second to last ( even though he was one of the fastest riders there) Because he stalled the bike.

not really. it is jetted wayy too rich from the box, and needs to be jetting correctly before one can judge. When this is done, there isn't much work in starting the bike, when the starting drill is sorted out of course (but thats true with almost all 4 stroke bikes). It's interesting to note that they all have trouble starting when new, but after a few hundred kays (harder to clock up on the YZ) they will start easier, even with the standard jetting if you must use it. Look at www.thumpertalk.com, as this issue has been discussed and the problem has been sorted out, especially in terms of starting technique. There are tips to start a semi- flooded bike also (after a fall), but i must agree that when the bike is flooded well and truly, then the only option is to remove the plug. Can be done with the tank on, but with the 400/426, the tank must come off for spark plug access.

i'm kinda fond of this place too. oh yea, very well ritten:)

Canberra Boozer:

Maybe I am spoiled from my very easy to start CRF 450 . I was just illustrating to the Troy with the YZ125 that there is a "drill" with a YZF250. (I can start it well, but many people can not). with a YZ125 there is no "drill". I actually was very skeptical about even buying a 4 stroke until I started a friends CRF450. Few things are more frustrating than stalling your bike and having to kick it over until you are exhausted while your competition roosts by. I even have a riding buddy that has both a YZF426(his) and a YZF250(his wifes) I have started both and I found the 250 to be the harder of each to start. I do however like the power of the YZF250, and if I was racing 125 class, this would be a good bike for me power and fun wise.

i know, i wasn't attacking your statement. You are right, but i thought i should add a bit of my starting experience onto your statement. :D
