Maybe a good way to get the class moving again.Our son started with a 440 when he was 8 and moved to a 650 after 14 months then kept moving so to speak.The junior class during 2007/10 was quite a large /competitive stand up class at National Level and took a lot of commitment from families to keep together.
Denny is right about costs.However the reality is that once riders start getting good they want to go faster and harder .IMO the big thing is to at least get juniors back out at club meets even as practice events at lunch time.The QLD Junior MSQ approvals and AJSBA junior rules have been there since 2005 .A lot of work went into setting the framework up so it would be great to see it used.
