Knee down?

[Dead Eye]

The justification is very sensible. Testing your abilities in a (mostly) controlled situation that you are prepared for so that its possible if the need arises. Obviously public roads and carparks aren't exactly the best definition of "controlled environment" but with a lack of money its the best alternative.

Teaching yourself how to ride and use more "advanced" manoeuvres just seems like a very sensible idea. With that in mind, good luck and don't wreck your bike ^^
