I too have been riding for over 17yrs and choose to ride a 250cc bike. Why should i be punished for the poor riding skills of learner riders. My bike green slip now costs more than my car green slip and i now i would do a lot more harm in an accident driving my car than i ever could riding my bike. Who is responsible for making this change? Someone needs to step up and explain the changes. Cost should be based on bike size and riding experience not just size!!!
