I recently did the XRL tank on DR350S. I did not follow the same exact method as the others, although looking at their posts is why I knew it would fit in the first place. I : did not cut the stock tank rear mount fabricated rear bracket adapter from included hardware and a small additional section of ~1/8" flat steel did not cut the nub off the frame put a little grease on the rubber pucks and slid the tank on over them bolted tank to frame/engine mount on left side only using bracket fabricated from ~1/8" flat steel removed rubber spacer between seat and tank for very tight fit ziptied included rubber frame spacer on top of factory metal heat shield (good idea to use both because inframe oil tank can get HOT) So this 5.8 gal XRL tank is 100% reversible to stock DR350S tank. I have not yet tried crashing with it, but I have jumped it and hammered it over potholed gravel roads and such and it has been fine. Front bracket v2 (v1 is behind it) Front bracket installed With Wolfman Enduro tank bag (can be located behind fuel cap covering part of the seat, or on top of fuel cap and completely off the seat) : I am aware that I'm lacking photos. I think the other two guys have it pretty well covered (see below), but I may add more photos later.
