Securing the passenger seat is as easy as placing it so the hooks/tabs are seated in place, and tightening the hex head bolt (will need to remove the rider seat). As for the tail light cover, your ktm dealer should still be able to order the oem part for it. Depends on where you’re located, but here in Australia I was able to source one a few months ago for a 19’ (I believe it’s the same part). Welcome to the RC life!!picking up a 2015 this month, the rear right taillight is missing the clear cover, any ideas where to get one? also are there special instructions how to secure the passenger seat? thank you for your help!
