Dirt Bike FAQ

It needs to be a 4 stroke, not 4 cylinder. The turn signals need to be a certain distance from the centerline of the bike. You probably can not take it on divided highways, I think it's a 250cc minimum. The lighting kits can be quite expensive if it doesn't already have the necessary lights, especially the tail-light and license bracket. If it came with the correct lighting then it is probably already titled as a street legal bike. You will just need a safety inspection and insurance.

Depends if you want to trail ride get a 230 but if you want to race get a 125 2stroke.

If your first qualification is used, that will depend on the bikes available for sale in your area. Couple of general points, though. At 5-11 you will need a bike with a full size frame. Tiny won't cut it, 125-250cc, but check it first, even at those displacements have seen 3/4 size frames .(kind for kids). Have you ever ridden before? If no, lightest bike you can find, you'll be picking it up a lot. Can't even tell you the number of times I've fallen! Check where you will be riding. Some sites have specific equipment rules. Don't spend everything you have, you will need some equipment. Minimum: Helmet, Gloves, Boots. Ever caught a lace in the foot peg in 5th gear so you could not shift? (not a lot of fun) Worry about weight, not displacement. You always have one piece of equipment that will keep you from getting in trouble by going too fast. (Hint, it's the place between your ears.) On Bike condition: does chain shift a lot side to side? Do tires show "age cracks"? Shake steering head, do top of forks rattle back and forth? On rear sprocket, are holes even or"dished" on side? All signs of wear, going to be medium to very expensive. If the bike won't start when you goto look at it, something is very(!) wrong. Get a mechanical friend to go with you to look at bikes to begin with. Ask what he is looking for, so you can do the same later. Best wishes, dirt down and sky up!

Look at a used Kawasaki KDX200. These are great for woods and trail. I am 260lbs and can stand mine up in a wheelie and jump just fine. Just don't do those things until your skills improve. You do not need a large cc bike. KDX's are very forgiving to a new rider as well. This is a 2 stroke. If you are looking at a 4 stroke, I would not suggest anything larger than 400cc. You can go a little larger on a 4 stroke than a 2stroke and be ok. Some of the 250cc size 4 strokes are smaller in size. The 250cc 2 strokes have alot of power, but would also be ok for your size. You would need to sit on them to see how they feel.
Definitely buy a used one for your first. This way when you lay it down, it won't get you as upset.

Headlight, turn signals, brake lights, horn, mirror.

If your vehicle isn't registered, then you need to register it with your DMV and put on the license plate, and pay registration fees every year.

Your off-road tires may or may not be legal. There's probably a "dual sport" tire in the right size that'd be better for street riding.

Based on your size, age, and skill level, I would recommend you start out with either a 100 or 125. These bikes will be shorter and easier for you to ride than the bigger bikes, say 225 or larger. You also don't need that much power for riding in the woods……….save that for a track later when you gain more experience. As far as brands, the kawasaki's and honda's are almost bulletproof reliable. Remember, you can always buy/trade for a bigger bike later. Get the smaller bike and take a dirtbike class, you'll be glad you did! Go to MSF.com (motorcycle safety foundation), they have a listing of a school near you. Good luck!

I am nearly the same size an weight as you, and I ride a Honda cr250. It is a 2 stroke and believe me it is not exactly a beginners bike! I would definitely suggest a 4 stroke Yamaha or Honda bike. You wont do any better as far as reliability and rideability goes. Since you are a beginner I would suggest you go for a 250cc 4 stroke bike since it is the perfect combination of controllable power and still having enough to be fun. As you ride for a while you will probably want the power of a 450cc or a 250cc 2 stroke, but I would not suggest starting out on either of these bikes. Have a good time, and dont be discouraged on your 1st day of attempting to ride!!!!!!! If you have any questions feel free to contact me.

As you have only the experience from riding the crf150f and are only 5ft 5 tall I think you may be better to wait till you are just a little taller before getting a 4 stroke 250cc. You would still be a good size for the crf150r or an 85cc and may be alright on a 2 stroke 125cc but think you should go sit on one at a shop before you thought about one of those. If you go for the smaller bikes you may have to be prepared to upgrade depending upon how tall you are likely to get. You can still race a crf150r and an 85cc for a couple more years. As a beginner at racing any of the known brands would be fine.
