KTM Quick-Lock Tank Bag 390/790/890 Duke

I've never owned a tank bag before, but rented an 890 Duke R that had this bag on it. When I bought my own, it was one of the first accessories I picked up. It's one of the few tank bags that looks like it was designed for the unusual tank shape. Good quality, snapping securely in place and easily coming off with a pull of the cable to gas up or take with you. It's small, but enough to put miscellaneous stuff in for a day ride without either stuffing your jacket or putting a larger bag in back. It's a bit pricey, but worth it for the convenience. Install of the tank ring only took about 2 minutes. Attaching the mounting plate to the bag was a little finicky because you need to drill holes (using a template) in the bottom of the bag, but still only took about 10 minutes.
