Those bikes [Nortons] have a ways to go before they are ready for prime time. And don't hold your breath waiting for them in the U.S. They have significant issues to overcome for EPA/CARB certs.
Don't forget, Kenny Dreer, the Grand Poo-Bah of Nortons here, tried for years to make that motor package work and gave up, leading to the sale of the Co. to the Brit. Agreed that the new owner has more money than Dreer's backers did, but reports from the UK on the pre-production prototypes are not encouraging; the motor still has issues. And the bike's price point is likely to scare you.
