What was posted here before was completely incorrect Beathalor is saying that you need to learn on a 250cc bike. I being an average sized guy started riding sport bikes on a 600cc R6 which is a good starter bike for a average sized person. Most women I have seen riding prefer the seat height and feel of either a 600cc GSXR or the 636 Ninja which has an even lower seat height. I advise against a inexperienced rider going out and buying a 1000cc liter bike that is just stupid, about as stupid as a 250 pound man buying a 250cc Ninja as some on here seem to think. Remember a bike is only as fast or powerful as you make it they don't go unless you twist the throttle. As long as your comfortable, can touch the ground flat footed and are physically able to hold up the bike you will be happy having a 600cc bike to grow into.
I think that the best pocket bike for a beginner might be the baja doodlebug. It goes a good speed for a beginner and it can also help teach them about engines and upkeep of a bike. Baja is a very good brand too.
a good cheap beginner bike is Orion 125cc
a 120cc dirt bike is suitable for a 17 year old
having been a beginner my self a couplke of years ago I would recommend you get your cycling legs with hybrid bike and once comfortble then get a racing bike a hybrid has a more up right stance and will hurt your bum less but is a good investment if you go for a Specialized FX series or Trek after you can do some distances regularly you will knoe what you want out of a bike
Any exercise bike that offers variable resistance should be suitable for a beginner. It is also worth noting that advanced features such as heart rate monitors are not needed.
your best bet would be a 250CC or 500CC sport bike
An older Honda XL100, XR100.
rockey mountain flow 1.0 is the way to go
Kawasaki Kx500, any year will do, but the best bike for a beginner is a Yamaha yz490
Yamaha TTR125 is the best dirt bike. I think itβs a good idea for a beginner to use a dirt bike with low engine power. Yamaha TTR is a perfect mid-size beginner bike; it has a 124 CC engine with four strokes.
I asked my buddy the same question. He said that a Yamaha CRF125 is a good beginner trail bike for someone that's about 5'8.
Sapient bikes are a wonderful beginner bike for young BMXers.....much better than mongoose but not as good as Sunday
