If you have been to an Arenacross lately, you'd also know that a 125 stands absolutely NO CHANCE of making it around the track safely, let alone being competitive. I'm a two-stroke guy to the bone, but there is NO WAY a 125 is:
1. staying on top of those whoops
2. triple-tripling the rhythm straight (double-double-double and you won't make the main)
3. Hitting the finish booter.
It would take a hot-rodded 150cc to make a dent, with a 120lb rider like McDade.
I've said it a million times, the only chance any two-stroke stands at this point, indoors, with the current rules is a 250SX KTM in the 450 class, at Toronto (small shitty track, small rider turn out)
