Cosmetic: I've added 3m paint protector on the gas tank (so it'll look brand new forever);fork gaiters; renthal superlow bars; shorty levers; folding bar end mirrors; small windscreen (comes off in 2 seconds); vinyl wrapped the side covers in flat black (looks factory); brake light flasher/modulator. Performance: PCV with custom dyno tune and map; Full 1-piece flat black exhaust (saved a bunch of weight and picked up some HP); K&N air filter; Hi Flow airbox; Brand new Pirelli tires put on about 200 miles ago. Bike has 8xxx miles; just had the oil changed and valves checked (they are spot on). The brake & clutch fluid is changed annually; the K&N was just serviced. Bike runs 100% perfect, and its still under warranty until July '18!
