I really like the idea of having a tow vehicle thematically complementary to the motorcycle that it's hauling to a weekend trackday. A vintage air cooled road race moto needs a vintage air cooled tow car! Buggies are short wheelbase vehicles; even those built on full length pans are still pretty short. And of course having engines at the rear of the vehicle also means huge weight bias toward the back. Yet clearly these buggies are towing some serious weight behind them. How are they able to do this without flipping over backward?
