My heart breaks everytime I read about a 16 to 18 year old that gets killed on their bike. Mostly because of inexperience or have no fear. My son is 18 years old and he talked about getting a motorcycle. I told him he could, if he took the California Highway Patrol sponsored class first. I truly believe young and inexperienced riders NEED to take some type of hands on class before getting on that bike. Moms would feel much better too!
I agree 100% wth having your son take the course before he hits the road. The problem is motorcycles are actually very easy to ride, especially if you "have no fear". But the fact is being able to "ride" a motorcycle is a lot different then being and to safely go out in traffic.
The course will be a big plus, but nothing can replace experience. Even the simple things like backing off the throttle, pulling in the clutch and shifting gears, need to become second nature and not something you need to think about. As soon as you take your concentration from the road there is going to be trouble.
Hope your sone has a safe and enjoyable experience!!!
