Are we talking of 'limiting age for National races' or 'National competitors must have ridden State events to be eligible'?
You can't restrict on age for many good reasons given above, where would you draw the line, 28, 34, 38? Next you'll want to restrict based on how many joint replacements you've had. It's hard when I (54) have to run against a 22 year old, it's going to be even harder when I'm 70 !!! But that's life, I wouldn't have it any other way, big boost for my ego when I beat them (helps me keep my young girlfriend too).
You can't have age races if you don't have the numbers, it sickens me at Vic roadracing at the moment where 'trophy hunters' get a second place award with only two in the race, back in the day my trophies were won with 60 bikes in the race! All racing must abide by the rule 'minimum 10 competitors or no race'.
I think it would be great if riders had to qualify for National Championships at State Champs, but getting the state bodies to regulate & participate in that would be difficult.
Absolutely LOVE the idea of having a bike show combined with an event, if I couldn't ride anymore I'd love to show my bikes off, I know there are many ex riders out there that feel the same.
Maybe there's a reason to have 'demonstrtion races'? Only need a recreation licence, no sheep stations on the line.
Funny that I don't agree with limiting ages in vmx races but I want to get modern mx age racing off the ground (as per REM in SoCal). Maybe because vmx has smaller fields and modern mx (the future of our sport) is fading-away because many older guys don't want to take the risks to save-face on the track? I am also pushing for riders over 50 in modern mx to be able to run with the 'M' prefix on the their race number denoting 'Master', relieving the pressure to have to make that monster double.
