I put Safari's on two new 2015's for my wife and I.
I sure wish the front, lower mounting bracket on the Safari allowed for more room. I had to have my wife fit both bolts and tighten them - my hands just didn't want to fit into the small space.
I found the plastic will / may reshape during shipping - probably from heat. I first put the tank on the first bike and it seemed the mounting hardware didn't want to line up right. I put the tank on the bike and let it sit in the hot sun for an hour - then we could pull and push on the tank to flex somewhat and make it easier to fit the mounting holes in the tank to the fixed mounting positions on the bike.
I also replaced the flimsy vacuum hose supplied with the tank for fuel line with regular reinforced fuel line - not fuel injection line.
Once we got them mounted, I was very happy with the solid feel of the tank on the bike. It has to protect the radiator to a great degree.
I imagine it will take 30-minutes to remove and 30-minutes to replace at valve check times. So far I feel this is a good product and probably worth the high cost of admission!
