I'd kill myself with a motorcycle. I'm not being melodramatic, either. I used to own a 2000 Trans Am WS-6 that I turned into a road race car. Stripped, caged, modded engine, suspension, brakes, etc. Built it in my own 2-car garage (usually with a Honda Pilot sitting so close I had to worry about weld spatter!) and eventually won the 2008-9 Louisiana GT2 championship with it. Sold that, and bought a 2-cycle race kart (KT-100). Only put out around 18hp, but would easily top 80mph on longer straights. And, co-drove an ICC shifter kart (125cc motor, 6-speed sequential gearbox, 44hp). Won or podiumed every race I finished over a 2-year period (got knocked off track quite a bit by newer drivers). Got in a big wreck, totaled my kart (broken frame, broken seat, busted clutch, bent axle, etc.). Repaired it and sold it. If I got a crotch rocket, I know I'd be going mach 3 with my hair on fire (to quote Top Gun).
