2007 Suzuki DR-Z 400s Dual sport with 3,500 miles. The bike is very clean and has several performance upgrades including: hotcams stage 1, jet kit, Pro Comp MRD exhaust system, Renthal handlebars and Moose hand guards. Very quick dual sport bike. I've used synthetic oil since I bought the bike a little less than 5 years ago with around 1,000 miles on it.
