You sir... do some ridingOver 12,000 now and had to replace the shift cable and one exhaust rubber mount. Parts are under $35.00 so far. It looks like the sport models will use a version of this engine package so I expect They will be very reliable too. Like most on the forum I'm getting tired of waiting although I didn't wait. I bought the 2016 Yamaha YXZ even though I knew it had a lot of problems that needed to be fixed. Got over 13,000 on it now.
