Rotax engines…reliability and lifespan?

I am new to Rotax engines and BRP. This is my first atv, but I have had polaris snowmobiles in the past. Just curious what type of mileage and hours owners are seeing on their machines? Can these go 10 or 20 thousand miles and 500 or 1000 hours without any major problems?

I understand every scenario is different and totally dependent on how the machine was ridden and how it was maintained, but just a general consensus?
