They stopped making the Banshee due to political reasons, not engineering ones. Still the scariest, fastest, most viscerally appealing quad ever made.
Mine is terrifying. Tuned to the hilt and rolling on race suspension, its probably the most intense thing in my fleet. The CBR is probably right up there, as I have not really capped it or this Banshee out on top speed yet. Not sure I can. The lowest-performance part on my machines is always me.
