Another vote for 13 + xm sleds, my 16 hasn’t skipped a beat in 4K miles now it’s the girlfriend’s ride. Only things I’ve done is rebuilt both clutches around 3k and had to replace the y pipe bolts. I’ve had multiple friends ride these things up to around 5-5.5k before doing a top end. These are 800’s with all mountain miles, look at the rental sleds around most xm‘s have a pile of miles. one of the local rentals sold 3 last year one had 9k another with 7k and the newer of the bunch had 5k, not easy miles I assume.
