I think there's already a taiwanese or chinese copy available. They're pretty quick to spot the trendsetters.
I like this thing:
CPI GTR 50. Also comes in a 4T 150 version.
From what I understand, they had to go to Triumph engineers to get the exhaust can made since they kept melting their prototypes. The 50 will do 60mph out of the box, derestricted.
