Many people think of riding a motorcycle is similar to learning to ride a bicycle: a skill that once it's learned it is automatic and unforgettable. However, this is not necessarily the case with motorcycles. There are a number of reasons for this, but the primary one is that over the years, bikes (and the laws governing them) have changed. Whereas a bicycle applies the same basic principles across the board no matter what year it was manufactured, this may not apply to all motorcycles. So, before you go out and jump on the next bike you see, you might consider taking a refresher course from a motorcycle safety unit to re-learn the mechanisms and the laws concerning motorcycle riders.
Because of the increasing number of people who are returning to leisure motorcycle riding after years away, there are courses that have been developed specifically for people with some skill but who need to work on brushing up on some of their basics. These courses also help them to get acquainted with any new or different motorcycle laws. This way you can be sure that when you get back on the road, you can do so with the full confidence of someone who knows what they are doing.
These kind of courses are also designed to help you get your motorcycle licensed renewed if it has expired. It can be intimidating enough to take a driver's test when you know what you are doing, but you don't want to go in blind. These refresher courses help you to get back on the road safely.
