So I'm snooping around the Supermoto website for South Africa (www.supermoto.co.za) because I'd like to start racing sometime... and I came across the "Class Rules and Regulations" Everything is fine and dandy until I get to this one... Grand Masters Class - any capacity motorcycle up to 450 cc 4 stroke. Minimum age 45 or older (to be confirmed) or you must have a recognised medical certificate from a reputable and recognised health institution stating that you have to use a zimmer frame or guide dog. Proof of zimmer frame and / or guide dog to be produced at scrutineering. Any rider over the age of 120 will require an ECG report. I would LOVE to see a race with those riders XD what's the weirdest rules/regs/etc you've ever found?
