My S1000RR, Grom, and R NineT. The S1000RR has a full Akrapovic exhaust. The Grom has a Toce exhaust, sprocket/chain upgrade, rear sets, Kitaco clutch cover, bars, shorty levers, and TST LEDs.
The R NineT is a 2015 and I went mad with that bike. Alpina tubeless wheels, full Ohlins suspension, Rizoma rear sets, Rizoma Clip-ons, Remus Headers, ACS silencer, ACS, levers, Rizoma turn signals, Rizoma swingarm plate bracket, reupholstered the seat in alcantara, and powder coated several pieces from silver to black. It's the forever bike. Even if it is less than comfortable. Worth it.
