Rode my friends RC8R a few weeks ago.
Loved the engine. Pulls like a tractor in every gear.
The engine is very smooth and the bike handles very well.
Two of the worst items on the bike are the mirror placement, and the instrument panel.
The mirrors are placed very low on the upper cowl to where you constantly hit them with each hand. Not very good ergonomic design at all.
The instrument panel has all sorts of readouts and such.
Unfortunately all the whiz-bang info takes up display real estate, so the numbers and characters are small and hard to read.
It's made even worse due to insufficient reflective backing on the panel.
So even in broad daylight, it's hard to read the panel.
I was shifting gears and often had no idea what RPM I was turning.
Maybe it's better at night.
