Beginner Motocross Bike ?

I would go for a cr125 as a beginner race bike as you don't want a too big of a bike to scare you off such a fun sport.

Your size and weight puts you right for a 250 or even an open class bike. I would suggest a 250 4-stroke until you get some skill, then move up to a 250 2-stroke. Since you are just starting out, I would suggest to look for a good used bike. You can save thousands and use that money for tools, riding gear, gas and oil. Look on Ebay, Craigslist and Bikefinds for a used bike in your area. Good luck, have fun and welcome to the sport.

Im a 5' 5" girl & everybody said I couldnt ride a 250 & people still cant believe I can.. Im perfectly fine on it .. Just take it slow till you get used to it... Then shred it =D

Do not get a 125. That is too small of a bike. If you weigh 200 pounds, you can easily handle a 250. Besides, if you plan on racing a 125, it will be too slow. Do not listen to your friends you will not kill yourself. Just don't pop the clutch or jam on the throttle. Take it slow. I think a 250 is the way to go for sure. If I were you I would probably get a KTM 350. That is a nice in between bike. I hope I helped. If you need more information just email me.

I normally would recommend a 125 2-stroke or a 150 to 200cc 4-stroke but given your weight you may need a 250 but ride it slowly till you are really comfortable and confident with the power. Welcome to the sport.....and good luck....

Well,if you want a 250,I would recommend getting the honda 250,because it is the same speed as the 85 cc 2strock honda,that they don't make those anymore. Becareful!
