I was travelling yesterday for many hours on a very hot day and noticed this for the first time since I ride this bike...

...when I switched to SPORT MODE at about 100-110 km/h it went into strange high turns for 1-2 seconds, it sounded like you would shift it from 5th to 2nd gear instead into 4th... this happened fast and than it shifted back to normal sound again.

Has anyone experienced this before? Is my transmission still working OK? I have not noticed this before...

PS: I recently had all oils changed...
 
When you shifted to Sport mode, were you in Manual mode or Drive Mode?

I get the 'hiccyup' in Drive mode when the lock-up feature drops out, but this is going from about 85kph to 80kph in Drive mode.
Sometimes switching Modes results in anomalies in RPM that is the ECM software corrects (my theory at least)

Ah yes, I forgot to say... I only use automatic mode... I noticed today it happens only if I am speeding and then shift to S mode, not if throttle is on zero while changing to S mode.

Mine has a noticeable downshift at around 115 km/h and at around 85 km/h. Seems like this is normal for this bike. We are not the only ones...

We (my daughter and I) have two DN-01 made in 2009. It is quite NORMAL when the HFT downshift at about 84 km/h, both of our motorcycles do it since we bought them (NEW) , no need to worry, mate ! Greetings from Québec, Canada.

Father and Daugter DN-01s, that's pretty Cool. Who else on the Planet has that? Are both bikes the same color?
