I will tell you from personal experience on our 2024 Polaris 650 XCR that we took to Longlac a couple of years ago, It is 150 miles/240 kms that the 850 sled made to 130 miles when all the 850's and Doo 900 turbo ran out and we kept riding it to see how much was left in the tank, got to Longlac and it still had about 13 litres of gas left in the tank so would have easily gone about 200 miles/320 kms before it ran out, So yes that puts it in right in the range of the 900 Ace non turbo for Range. Bear in mind we all kept our speeds down in trying to be mindful of getting there.
We are heading that way next week and will be seeing how the new 2026 650 does vs the 2024
I'm a Polaris guy riding a Cat.....,
But, this motor and chassis set-up is great and quite honestly second to none.
Decent deal too here:
