I have a phantom black 2007 model. I had the S4 alarm fitted and, to date, I can't fault it. The engine is the perfect blend of low down lazy torque and rev it hard power, whilst the agility is only let down by me. That said, it's the most stable bike in adverse conditions I've ridden in the decade I've been riding. For example, imagine this scenario: heavy rain, down hill, off camber corners, huge diesel spill. Despite all that, it still didn't fall over - all it needed to remain upright was the dab of a toe. Very confidence inspiring.
Looking to take it to Spain in the summer so I'll let you know if any niggles crop up.
