OK don't learn to drive a motorcycle and a manual at the same time. Makes it much harder to get started.
Also for your first motorcycle/learning bike don't use anything nice. You are going to lay it over, scratch, dent, and ding it no matter how hard you try. I do not think your dad will want his motorcycle banged up unless it's a old bike.
Our state doesn't requires a class, but if you have $100 to blow, goto the local Harley Davidson shop and sign up for their class. Good training program there and people who have no issue telling you everything in black and white.
Dirt bikes are good starters bikes, if you can't handle a dirt bike you really can't handle a motorcycle. Also dirt bikes are more rugged and laying one over wont damage it as bad.
My instructor told me this when picking a bike.
Take your weight and double it Thats the amount of CC's should be about what your looking for in your first bike.
so 190lbs = 380cc's.
you need a bike you can easily handle the weight of. If it's to heavy that bike will kill you. here's some help.
1. One that is short enough you can easily touch the ground
2. Light enough that you can lean on one foot and support it with little effort.
3. Bugshield/helmet with faceshield (getting hit in the face by a hard shelled beatle sucks to no end and can cause you to react badly running off the road.
4. Go moderate- you need a starter bike not a 170mph racing bike, or that brand new 1100cc harley.
5. Get a leather pants/jacket to wear. Don't be a idiot and wears bluejeans and a tshirt. You may think it looks cool and feels better during the summer, but those items will save your life (and your spine).
6. Learn to drive in a dry parking lot - Loose gravel/dirt/mud/pot holes/rain are very dangerous when your first starting out.
7. Sign the back of your donor card : )
8. Have fun! if you stop having fun then stop riding : ) i'ts not for everyone. Personally I've had my license for 3 yrs after my second year i sold my bike and bought a sports car.
