Dirt Bike FAQ

Only if you think guys like McGrath, Cooper, Carmichael, Stewart and Gosselaar are still babies!

Tons of adult pros race and ride minis. The minimoto nationals in vegas actually give out a #1 Pro AMA plate to the winner of the pro class. Big money and big fun on little bikes.

The maintenance schedule will not be anywhere near as intense for a 2-stroke when compared to a 4. The top end will probably be the biggest hit on your wallet. Expect to do this every year or two (a lot more if you get into racing with it). People on here will say stuff to the effect like, you have to waste time measuring the oil to mix in with the gas. If you think about it, as much as you're changing the oil on your racing 4 stroke like maintenance requires, you'll be dumping every 2-3 rides almost the equivalent of what I'm mixing in. Use a good synthetic oil for whatever bike you choose (my personal favorite is klotz, but there's a lot of good stuff out there). Of the 3 bikes you listed the YZ is the best bet. Honda's CR250 is no longer in production and had weird jetting issues. The KTM SX is super light but does not have the power spread of the Yamaha or it's spot-on suspension. Is the new bike going to be used for trail or MX track? The KTM 250 XC would be a better bet if you plan on riding woods.

That really isn't the best way to find a dirt bike for sale that you are looking for. The likelyhood that somone would respond with one within your price range and within driving distance and the type you are looking is slim to none.

Your best bet would just be to go on ebay or craigslist. If there aren't any up, you could try looking under ebays completed listings at bikes that didn't sell and ask to see if they still have it and it's still for sale.

And one last thing, 2 stroke vs 4 stroke really does make a difference. the 2 stroke 250 would be more along the lines of a 4 stroke 450 powerwise. I'd reccomend a yz250f.

Ok, most def a 125 is too small for you, 250cc is about what you need, If your looking for speed get a 2 stroke engine with a power band and a jetted carb. If your just looking for something to ride casually and you don't want to show-off on it, get a stock 4 stroke.

Two-stroke engines have the potential for about twice the power in the same size because there are twice as many power strokes per revolution.

I'f your just starting out riding dirtbikes and don't know how very well DO NOT GET A 2 STROKE.
Start out with a 4 stroke or you might kill yourself, fast dirbikes are very dangerous, I know from experience.

other than that a 125 is too small for you, I have a 250 and I'm 5'8'' 155lbs.

Sorry I don't know kilometers (usa) but the max speed would be about 110 mph on dirt, and about 95 mph on the road. 0-60 (mph) in about 3-4 seconds.

As I said in your other question to have a look at the 4 stroke 250cc but you are a good size and height for both the yz125cc and the cr125cc but you would also be fine on a crf250r or a kx250f

I think your friends have it about right. I like 2 strokes but in 2009 every one is going to stop making them and go to 4 strokes. if you wanted a 2 stroke I would go with a 125cc two stroke. if you want a 4 stroke, i would say no smaller then 250cc.

I think you should look for something in the 250cc range, good power, balanced. And you can touch the ground….j/k Try the 250, RM250 from Suzuki is nice

Agree with him, buy a larger one, and maby he will pay for a little of it after he rides it a 125cc-250cc is good nothing more

You are going to grow a little more before you wear out a bike. A 125 might be too small for you. I would look into a 250cc four stroke machine. Or I would look at the new KTM SX144 two stroke
