I saw one with a Chevy 502, guy had just gotten it came into a parking lot, sounded mean, turned to park it in a parking spot and almost dropped it right there. Didn’t look like they were easy to ride especially at low speeds, I guess on the highway they'd be ok.
I saw 2 Boss Hosses at a bike run..al I can say is they are HUGE!! I couldn't imagine tryin to handle a bike with a 502 w/600hp!!!! Gees who needs nitrous. They are quite expensive to..about $40-50k or more!
