bike or

im 15 i have my permit and my mom has given me the very reluctant "ok" on me getting a motorcycle(shes not irresponsible for doing so she just understands y i want it) so what is a good starter bike for me? i like the yamaha R1 an the suzuki k8 gsxr but im not sure if those r too good...i dont...

so I'm 15 and i want to put an engine on my bike. i think that you don't need a license or anything if it is under 50cc and it is not capable of going over 30 MPH. so anything else i need to know like requirements for over 50cc and other stuff like where i can ride it and stuff.

Does anyone know where I can get a pink pit bike/dirt bike has to be at least 100cc.

I have recently bought a a Roger Black Exercise bike and cross trainer. The screen on it stays at zero and dosen't show numbers. What shall i do to fix this.
