you nailed it, it is know as the "ELR" (or eddie lawson replica)
retro looks, but it is a throughly modern machine.

a pipe and jets is good for an easy approx 135HP.
good thing the stock brakes are 12 pots on 310mm rotors up front.
twin rear shocks, but completely adjustable at both ends.
torgue monster, something like 80% at 4K on a 12K motor.
