This bike has been treated with love. I have always used full-synthetic oil. I have the red key and black keys. and the original documentation and manuals. A full list of customizations and add-ons is below. A few things to note are custom-fabricated bracket to hold the aftermarket smoked LED lighting and turn signals. Tail was chopped. plugged and simplified with a smoked/ integrated brake/blinker/license plate LED. Copper accents throughout the bike including triple trees. mirror ends. extended reach foot pegs. levers. and old-school 'Ducati' logo. The ugly side panels that covered wiring below the seat were removed and wiring was relocated under seat and hidden. I added a lower profile Renthal handlebar. matching grips. and bar-end cafe-style mirrors (they can be flipped up if you prefer). I also plugged the original mirror holes. The motor. trans and belt covers have been coated black and I added front and rear axle covers/crash guards and a carbon-fiber seat pillion. Brand new tires (less than 50 miles on them). The 620 Dark Monster gets even better with customization. A responsive and uncluttered fuel injected* 360 lbs. A simple torquey motor without the mess of water cooling hoses or an oil cooler and you never hear about these overheating.
