Need answers for beginner biker!?

the bigger the motor the the more power and speed so a 250 cruiser will take you up to around 70mph were as a 600 cc sport bike will take you to 150 mph real quick, and sport bikes for a beginner the best one out is the Kawasaki Ninja 250cc plenty of power to have fun on, as for cruisers the Honda Rebel 250cc is a good one for someone starting out as well get a used bike if you can and don't get anything over a 600cc in cruisers as most of the modern sport bikes in this range are not for a beginner ,and I don't know if any company's lease motorcycles ,as far as insurance goes I have Foremost and pay $321.00 a yr ,insurance it goes up quite a bit if the bike is a sport bike another thing to keep in mind when your looking at bikes
