116 links is correct for that combo. 13/49 is much nicer on trail and 15/49 for open road or open terrain. I've used them all 48, 49, 50 rear with 13/14/15 countershaft. After running the 50 for a while I felt the 49 was better, and that's the leftover one from the 530 that I just put on the 500, along with the same chain. Lots like the 50 rear/14 front combo. I went back to 14/48 before installing the 49 and it was too quick for trail for me, even with the G2 throttle tamer, that's why I installed the 49. I had the stock chain with the 48 and it moved the rear wheel pretty far forward which is probably another reason I didn't like it on trail plus I tore my knee up with that gearing on and just recently smashed my foot right after reinstalling it and going for a trail ride. Maybe it's just a bad luck combo for me.
