A kx 110, not to powerful, umm a good beginner bike

Wanna buy a crf150f?

We need more info. Do you have past experience? Your riding style? Height? All these are deciding factors we would like to know. If this is your first bike ever, your best bet would be a mellow trail bike, like the CRF150F or the KLX140. These bikes are great for beginners, but you will get bored of the power quickly. If you race, these are totally out of the question. If you decide to get one of these, don't make the mistake I did. I got an XR100 for my first ever dirt bike, and I got bored of the power output in a matter of days. I wish I had bought a slightly more powerful bike. If you do have past experience, or don't but feel brave, get an 85 or CRF150R. It will still scare the crap out of you at first, but you will thank yourself later for getting it. Out of the two, I would pick the KX85. It is lighter, less maintenance, and more fun. If you race, the CRF150R would be the better choice. You have a picture of a KX85 as your display pic. Is it yours? Assuming that it is, it would probably be best to keep riding it until you are absolutely sure you are ready for a 125 or 250F.

well i always go with kawasaki because i think they are the best bikes,, u should look into either a kx 85, or a klx 140
