Posted - 04 Jul 2012 : 10:29:41 AM This class could be the first major change in many years so I think we should get it right from the start. So what is a Thunderbike? I will give you my opinions to get the class started. A cross period class to accommodate a specific type of bike as follows:- A 4 stroke air cooled bike of 1,2 or 3 cylinders up to 1300cc limited to 2 valves per cylinder. Frame to be of steel tube construction with twin rear shocks. All bikes to comply with current M.A. rules. I invite your comments.
