Hey guys I am new to the site and dirt bikes in general. I am switching over to dirt from racing sport bikes. I am comfortable on 2 wheels and am contemplating a 450. How much of a weight and power difference is there between a 250 and 450? I think I should probably start on a 250, but don't want to rule out the bigger bike. I am 6' 160-170lbs if it makes any difference. As far as the 250's go, what is the best all around 250? Pros and cons of each bike? I have always rode Yamaha, but I was reading through another thread that broke down the 450's and noticed Honda seemed to be the favorite. I am looking at newer (not new) bikes. My price range after buying gear is going to be around 4-5k.

Your weight is perfect for either a 250F, 250T, or 450F. I would read various tests in magazines. All of these bikes are good with some pro and cons. Yamaha 4 strokes seem to be the most reliable.

4 to 5K? Puts you in the market 2009 or 2010. Also, contact dealerships with left overs from prior years. I recommend buying a NEW fourstroke if you can afford it. There hasnt been radical changes in the last two years.

Heads up... you can buy a 2006 to 2007 YZ 250 two Stroke from 3 to 3.5K. Puts some cash into it (new top end) and will be ready to rock.

Haha I almost half expected it asking the questions that I did. It is the internet and opinions are like assholes.....everyone has one. I am just looking for a little info along the way to help me get into a new sport.

Aren't 250's being faded out? All the big manufacturers seem to be pushing the 4 stroke thing

Here is a link to the 2011 Racer X 250 shootout. What kind of riding do you plan on doing? Track,trail,hills? I say go with a 250 as a noob, but that's your personal choice.
Thank you for the link. Have there been many changes from 08-11? I plan to do mostly track with a bit of trail riding.

I've seen quite a few times how road racers are surprised with the power of dirtbikes. A 450 is alot of power for newbie to motocross imo.

I'd go for a yam 250f or a 125.

How much of a learning curve is there? What major differences besides power is there? I feel confident enough with my ability on 2 wheels to be able to control the bigger bike if I went that route. Throttle control won't be an issue.

Besides the obvious, what are the differences between a 4 and 2 stroke. I know how the power is different, but is a 2 stroke competitive nowadays? There obviously is different riding techniques due to the higher power band. Is there any difference in weight? 2 stroke 250's race 4 stroke 450's and 2 stroke 125's race 4 stroke 250's correct?

I have been riding on and off for 20 years or so and have had 125, 250t,250f,450f, and prefer the 250f over all. I loved the 450 on forest roads and wide open trails but I found it to be too much on the track, too tiring and a hanfull when you do get tired and arm pump. 250f I feel very comfortable on even when I tired a bit I can back it down for a couple of laps then go again.

Manhandling a 450 around a rutty,bumpy track, full of jumps can be huge difference.

Learning to jump a bike can also be taunting. Atleast with a 250f you know your not going to the moon ,if your arms lock.

Do you have any mates with bikes you can try?

I wish I did, but am new to New England.....hence why I am making the switch over to dirt. Always wanted to ride dirt, but there was nothing going on where I used to live. I think I have ruled out the 450 as of right now. I am not a very big person and would rather be able to toss the bike around than have to manhandle it.


Thanks for the input pacetruckdrvr

As far as racing goes...what races what and where are the advantages.

Welcome to Vital. As far as your question for 250f's I would say the best all around 250 is the Yamaha. Best stock suspension, decent handling, best reliability, good resale value and smooth power. If you get into racing seriously, you will need to upgrade the motor. Just look at shootouts by magazines and you can get an idea of what you will like about all the bikes.

Why 250t and not a 450f? Don't they race in the same class?

Depends on what you can afford. If you can get brand new, get a new 450. They are all good.

If you can only afford a new 250F, they are all good too but I would get the one with the most power (whichever one that is).

If you can't buy new and have to buy a slightly used but newer bike, go with 450s only. Look for low hours. Take someone that knows what to look for. Never shop for used bikes at night.

If you can only afford an old bike (like 10 years old), it starts to become a gamble on any bike but 2 strokes are sure easier and cheaper to repair. I, personally, will never go back to 2 strokes unless they somehow make them drastically better (like traction control or something). I prefer the torque and broad power of a 450 over all else (regardless of type of riding....hills, dunes, tracks, desert).

I can afford a fairly new (possibly year old new leftover) bike. Why do you say go 450 only when buying a slightly used bike?

Word of advice, don't mention that. Ever. You will make Vital meltdown with 2 vs 4 stroke threads.

Another question.....with street bikes for track use we switch to GP shift (reverse shift pattern making it 1 up 5 down). Do you do this with MX?

I would not buy a used 250F. Too unreliable with a limited lifespan. When things go wrong at 13,500 rpm's, they go really wrong. Buy a new leftover cheap, there are plenty out there. Yamaha still has a carb, so fewer things to go wrong and the engine hasn't really change since it was introduced so there are plenty of parts sources. Good power, but not too much.

A honda or yamaha is great for the casual guy, really reliable and typically good bikes. Buying used I would also take the 450 for lifespan issues as mentioned already. Hondas typically look the least clapped out over time in my opinion. I personally have kawis but they tend to get clapped out fast, even though they are great bikes.

I don't think you will find a 450 as hard to ride as people make it out to be. Good body position and being smooth, and you can have perfect amounts of fun. It can also be nice to be lazy out of the corners and just blip over the jumps at the end of the day. I have both a 250 and 450, I would say they are about the same amount of fun to ride. The 250 is fun if you want to attack the track, scrub, etc. The 450 is fun if you want to destroy buddies with roost or just ride casually.

Why is a 450f more reliable than a 250f?

no reverse shifting. I never switched my road race bikes to reverse shift either. It's all automatic for me; I didn't want to have to think about it. I never was bummed for having standard shifting. You could make the same arguments for doing it on a dirt bike as roadracers do; however, there is no quick and easy way to reverse them on dirt bikes (like there is on street bikes).

Since I was never 100% street, I was always riding/racing a mix of dirt bikes and street bikes, keeping them all shifting the same way just meant an easier transition for me to jump on different kinds of bikes.
