4900 miles on my 2016. I bought it in March of 2017 new. My only disappointment is the oil consumption issue that is going to get fixed this winter, weather Yamaha takes responsibility for it or not.
It has never missed a lick and still feels as tight as it did day one. I’ve had various rattles along the way that I’ve found and fixed. The tie rod ends have been changed as they were loose and rattling, the knuckle bushings were changed as they were getting play in them. These were done at around 4500 miles. I started leaking fluid out my rear dust seal around 300 miles ago as my drive shaft coupling nut has become loose. When I’m done using it for hunting I’ll take care of that. All parts are ready and waiting.
I’ve changed 2 axle boots and had one axle start popping and installed a heavy duty one. It began making noise after 750 miles so I dissembled the original and put it back together and re-installed it and it’s still going, so all original axles at this point.
Given the fact that I mostly bounce around in boulders I think it truly has been a durable machine and even though it’s an oil consumer it runs fantastic!
Edit: Also replaced rear brakes once!
