Need help deciding - 250 or 450 dirt bike?

Ride around on a buddys 250 for a while. Then buy a 450.

 

So Aaron, what did you decide to get?

 

Place a bad #$@ pipe on it and wake up the whole town..

 

im 6'1, and 220. I race a CRF250, i think the 250 will have plenty of power for you. The only you may have to do if you start doing motorcross is just adjust your suspension. I beat 450's everytime im at the track. Just personally ive havent found a need for a 450f yet.

 

Go here Thumpertalk.com then read, read, read.. Post up a question or two. You will get answers from real riders who love to ride.
BTW current offerings from yamaha (Yzf250 Yzf450, wr250f wr450f) are the same size physically the only difference is engine size, both offerings will scare you pretty easy if your not experienced.
I agree with Woody6047

 

I used to ride / race a 2003 KTM 450 sx and I loved it. After having this bike I would not recommend getting a 250F, as others have said - once you get comfortable with the 250F, you will want something with more power. The 250cc four strokes were meant to replace / race with the 125cc two strokes, which should tell you something about the power output.

My preference on manufactures: 1) KTM 2) Yamaha 3) Honda ... Again, this is a personal preference, but it comes from what I've seen, ridden, and heard from buddies who have ridden their respective bikes. There's been a lot of talk about Hondas, I would stick with the Yamaha, or go for the KTM!

The one thing that I really loved about my bike specifically, was that the 2003 model 450 sx had the same bottom end as the KTM 450 MXC / EXC. Because of this, I was able to grind out a shifting stop on the shifting fork and install a 5th and 6th gear from an EXC (leaving 1-4 untouched). This gave me the best of both worlds (IMO) - I had the MX transmission for the track, and the enduro transmission for the sand and open country. Most MX bikes will top out around 70-75 MPH; my bike would go over 100 MPH (fasted I was ever clocked was 92 MPH) because it is just gearing at that point. The engine in the KTM (specifically, and other 450's) is insanely powerful; it will let you go anywhere you want to go. With your body frame, that is definitely the way to go.

 

Nice picture, my buddy would love that.

 

i am 5'8 and my weight is 158lbs and ive been riding for 5 years and i dont know what size of dirt bike i should get any suggesstion

 

Ktm 350 best of both worlds. Small and light like a250, but a450 engine

 

250f. Step up to a 450 when you win every race.

 

I love my YZ 250. It rips at the track, but sucks when I take it on trails. Gotta mix gas and tune for altitude. I may pick up a CRF450x in the near future for trail riding.

 

450cc is too big and heavy for offroad. Even for a big fella like you, it will wear you out. Ktm makes a sweet 350xcf. Rides like a 250 I've heard. But lots of power. I ride a ktm 250xc and man does it have balls! You've got 55lbs on me though.

 

In my opinion, 450 is easier to ride. Rapid acceleration is less technical, making jumping easier, and the added weight helps me hang on to the bike with my legs when in the air.

 

Considering your height and weight, the 250 is going to be a bit small. Granted at first the 250 may feel like the right amount of power, the 450 will be the better bike for you in the long run. Just because it has tons of power doesn't mean you have to use all that power right when you get the bike! The 450 will be a little bigger size wise and will definitely weigh more. It's a great bike to cruise around on though. Personally though, I'd never get a Yamaha 4 stroke! Honda all the way

 

250 2 stroke carries me just fine. Feels light. 450 4 stroke: heavy! A real beast to push around in the bush.

 

With your height an weight 450 is the way to go.

 

250...2 stroke! Actually for a first timer one of those would probably kill you the first time you touched power band haha. But seriously a 2 stoke would be something to consider. If you put some time in on a beefy 125 you'd straight up rip on a 250f. And they're relatively cheap to own. But for a 4 stroke get a 250 and when you're ready (if ever) trade it off for a 450. If you learn to ride one, a 250f will do just about anything you want it to except maybe dunes, which is something i have no experience with. Because power isnt everything, you can get hurt pretty bad if you have little experience and hop on a 450 thinking throttle is the key to everything. Whatever you decide, good luck! Doesnt matter what size you get, im sure you wont regret it.

 

You're size and weight could handle a 450 fine, but for your prescribed use a 250 would suit you better. I have a CRF230 and it is snotty and moves around fine. I can keep up with my friend who has a KX125 smoker.

 

Shit, this thread is 3 years old, doubt the OP has checked on it in that long, DEERRP on my part! Lulz
