To get people interested in minimoto in your area.. You have to rely on a hell of alot more than just posting up on a forum..
First things first.. Secure yourself a venue..
Massive advertising is in order to get people turning up to the track.. Then with the continued advertising, 'word of mouth' from those riders will get more numbers showing up at your track..
There is certain people and places that you want to target for the advertising.. You must offer all classes of pocket bikes, from Cag to Euro..
Perseverance is the key..
