I would agree. How do you know it has a bent valve? Did the dealer tell you that? If so, have they explained the root cause? Valves don't get bent for "no reason", especially on a machine with 160km (which is about 100 miles I think).
I have over 170 miles on my 2018 (I just got it earlier this year) and so far it's been great. I've only had one issue so far (which I haven't figured out why yet), which was the cooling fan not coming on when I was out riding in the woods one day. Luckily, the dash flashes at you to get your attention, and I noticed right away the coolant temp was high and the fan wasn't running, so I shut 'er down and started checking stuff. I think maybe the fan has a dead spot in the armature or it was just a bad connection at either the fan relay or the fan connector (I unplugged both and plugged them back in), because everything else checked out ok - fuses, relay, etc., and after I checked everything and started it back up, the fan came on. It hasn't happened since. Still though, I may add an auxiliary fan with a manual switch as backup, just in case (since I'm already planning to add a secondary GEP PDM for all my accessories). It'll cost less than $100, so cheap insurance if you ask me.
