| Catch can, if you get rigid and ban all catch cans that once used to hold a beverage (AKA only allow AMA approved units that will not crumple/break in a fall) you are just going to drive off some people, and still generally be ineffective for the most part on a track like this. Small oil spills on pavement just aren't that big a deal. Indoors, on concrete, that's a whole other story.
As far as protecting the pavement from crash damage:
All levers should have ball ends
Bars should have round bar ends, Hand Guards that use the bar end for a mount should be inspected on an individual basis to make sure they don't have any protruding edges
Pegs should fold
Folding tip shift levers?
I'd suggest swingarm and fork sliders, along with peg sliders, but 99% of people won't bother. Heck, I still haven't sent my swingarm to the welder so I can mount slider spools to it.
Classes: I wouldn't bother getting hung up on dialing in 'the perfect' class breaks. Trying to sort bikes by displacement will guarantee HUGE discrepancies in power no matter where you draw the lines. Case in point, stock import 125s vs dialed in 124 +R motors, no comparison. So instead, maybe consider 'A' and 'B' groups, and have riders class themselves based on skill and speed on the track? (Riders can be bumped up/down at manager's discretion to keep things even.) That way a skunkworks 86cc rocket from hell can race against comparable lap time racers rather than trashing Moto8 and not being challenged. Conversely, John Q Scaredtotwisttherightgrip with a clapped out stock Lifan 140 can run with others pushing his pace rather than trying to fend off built MotoHP 150 +Rs. |
