We treat the Piaggio as a motorcycle in the ERC, but use slightly different criteria for the u-turn exercise because of the dual track feature.
I have riddent the Spyder, but only on a limited basis in a parking lot. We coach the 3W BRC in Texas and have a Spyder. It’s completely different than anything I’ve ever ridden! It’s much closer to some sort of “sports car/trike” type machine…a lot like an old Morgan, but with bars instead of a steering wheel. It IS a little weird (like any trike, or hack for that matter) because it leans the wrong way! The front end sticks like no tomorrow. The electronics won’t let things get too out of hand though. No slipping, no sliding..
