High revs on MXU450i LE
« on: July 04, 2021, 09:35:51 PM »
Just curious, I just got a 2021 MXU 450i LE and took it out on it's maiden voyage (Badlands Off-Road Park Attica, IN) and it seemed to me that the machine reved very high.  As an example, I noticed that getting the ATV to 10mph the tach was at at ~4K RPM and the engine seemed to whine to me.  As I said this is a new machine and am just looking to see if this is normal or do I need to adjust something?

I have a UXV500i which is a slightly different machine but the drive design philosophy is the same. Mine just about makes 40 mph since after break-in at about 7000 rpm. 10 mph @4000 rpm sounds about right for a Kymco sxs.

Really nothing to adjust unless you want to dribble around with roller weights and springs in the CVT. Kymco sxs machines are utility work rigs like tractors. Most other brands seem faster...

This is a quad, not a SxS. If it is supposed to rev high like that, it's fine. It's just that the other ATVs I ride with don't seem to do that.

What was your dealer's response to your concern with the revs?
Did you get a test ride before buying?

And, I'm feeling a little peculiar.
