I wonder about that new Honda parallel 1000cc twin in the African Twin.
Maximum power: 70 kW (93.9hp) @ 7500 rpm
Maximum torque: 98 N.m (72.3 lb-ft.) @ 6000 rpm
The whole motorcycle is just over 500 pounds, probably a light motor. I think just keeping it single RWD and mounting the motor behind the seat and cabin would be the way to go.
Something like this
