I dislike standard KTM switches ADR & start/stop switches, they require pedantic maintenance to retain function after every ride and aren't waterproof. airbox drowning jetting from new 2011 went to a six speed box The 2010 model has a slightly different frame, welded a few mm lower at the headstem which allowed them to rotate the engine forward a tad to improve handling and lower the center of gravity. The 2010 also came with lighter rims than 09, and a slightly different airbox - said to give better spread of dust over the filter and help keep water off it. Extend and re-route the gearbox breather to a better place to avoid getting water in the oil, water gets in there easily with the stock breather (unless they've fixed this for 2013).
