I didn't like the seat styling (from C-racer) but the rack idea was good. I like the Holeshot style, I'm guessing there would be import duty on top of that price too. I had to pay duty on a new CDI for the H1 from the US.
The Corbin Euro site lists their seat at £655.20 - I'd want someone to measure my bum for that price.
