Well, you'd need to bring non-alcoholic beer, because I don't think he drinks alcohol. At least he didn't when he was a bit younger, don't actually know now. But he has said he watches his diet so as to stay in top shape. I also don't think he would ever write a tell all book, he is conservative about revealing dirt, and was always willing to internalize the shortcomings of his race environment. He never threw his employer under the bus, even when they deserved it, so I doubt he'd do it post career.
If you did go out for a visit with him though, you'd discover he has an amazing dedication to the sport, loyal to a fault, and loves to have fun. Speaking of dedication and work ethic. He logged over 680 miles in his last test at Jerez. His best lap on the Wsbk CBR was one tenth slower than his RCV-RS MotoGP Honda qual lap. This was practically his first time on this bike in decent weather (the first test was a wash). Keep in mind the Wsbk CBR is considered by far the worst amongst Kawasaki, Aprilia, Ducati, and frankly I'd even say not even as good as the R1 will be on its return. The lap would have been good enough to put him on pole for the Wsbk round this year. That statistic should also give us pause in analysing his last two years in MotoGP, where the machines and tires are supposed to be superior. It should also indicate what a farce HRC sold to satellite open class teams, RCV-RS, which have switched to Ducati for 2016. Basically Nicky was competing the last two years with a bike probably not as good as a ...... Wsbk CBR if we are to believe the Bridgestone open class super soft tires were at least worth a tenth.
