For u.s. motorheads, there's not much better than a roller small block revving like a beast. There's something viscerally familiar about this motor because of it's similarity with the greatness of the pushrod v-8. Big cubes gets the torque, electronics deliver the economy, the design allows it to rev well (unlike another american pushrod motorcycle motor) and it should all be bombproof if done well.
I love it and hope they have success.
Supermoto bikes exist so that 40 year old men who know better can act like total assholes.
