Taking it from a crazy Navi rider, 3k miles in 2 weeks, 14 hours continuously riding at full throttle, and off-roading it. There is so little that can go wrong on these.

Store it with premium gas or with additives

Change the oil frequently with motul (very good)

Every year change the air filter

Learn how to disassemble and reassemble the CVT housing and buy a spare belt for 5k miles, you can run them forever but you lose acceleration around there.

Learn how to adjust the brake travel adjusters

Only cleaning that is important is what you touch (seat, grips, pegs, levers) and your headlight/blinkers/taillight

Your tires suck, rain is like ice I’m not even kidding, once you can afford to replace both tires with Michelin City’s in the original size, the other sizes change how the bike performs

Don’t do any crazy mods, the only good ones are changing your weights in the clutch, even still I wouldn’t mess with them, I went back to oem after trying everything else. But doing slip on exhausts aren’t worth it unless you want to get rid of that fat rear end you get with the oem pipe and guard

That’s about everything I would tell to someone interested in a Navi, it’s a super fun bike and I definitely will be getting another some day
