I have a 2021 M SE. Engine runs strong. Very snappy. 300 + miles. Had re clutched for high elevation.
I do not like the primary clutch. Very weak at engagement. Once it's moving, its lots of fun. I Purchased it for my granddaughter. It has only been used on Togwotee pass, so I can't say how it would do at lower elevations. I'm still waiting for the shock upgrade kit, I ordered in September. Overall its a nice sled.
