SE down shift RPMs

[RAL]

At what RPM does the SE generally auto down shift. Trying to see what the Rotax people think is acceptable for the lower rpm range. See many cautions about running the engine at lower RPMs but shes has a lot of ump in the low end. Some on here seem to think running below 5000 will hurt the engine, with many pushes of red line needed regularly. On the flat in 5th gear at 55 yeilds great milage and shows no sign of distress, so whats the true skinny?

Mine normally downshifts at 2500 RPM, except for going from 2nd into 1st then it happens at 1800 RPM.

55 mph in 5th gear you should be running about 4400 RPM. Most on here say to keep the RPMs above 4000 at all times, with over 5000 being even better.

I think the manual says 2600 rpm for the downshifts. I usually shift before that except from 2nd to 1st where the auto shift seems a little smoother. No doubt that the motor is happier above 4000. Will you damage it below that??? I doubt it, but the motor certainly prefers more RPM for decent acceleration. No different than starting a manual car in third. You can, but it sure doesn't feel right!

I'll run as low as 3000 rpm if I'm just cruising around town at steady speeds.

Just got back from a rydem so I can confirm a couple of things.

55 mph in 5th gear is 4400 RPM.

65 mph in 4th gear is 5550 RPM.

I did not get over 4th gear on the ryde today, except for the one time I wanted to let it breathe and ran it up to 100 again.
