100 kph (62+ mph) = 6000 rpm same as mine. 2013 DT300i.
120 kph (74+ mph) = 7000 rpm seems a bit high but not by much.
My rear tire is overall one inch larger outside diameter than standard so my rpm's will be a little lower...

2019 XTown 300i---I run on highway between 6,000 and 7,000---indicated between 60 and 70 mph----RPM may increase a little as belt wears.

I have no idea what full throttle is in mine. Never been full throttle either riding or testing on the center stand. I don't need to know...

I'm at 6000rpm at 110kph, and just under 6500 at 120kph. Under wide open throttle, which I haven't done much, I've never seen it over 7000. These figures are however with 15gram Dr Pully sliders installed.

It'll take it, but anything on my XT300 over 6,500 rpm starts to feel a bit rough.  This may ease up when fully loosened up (it's only done 1,400 miles), but for the moment I limit myself to only occasional forays over 6.5K rpm!

If it's not infra dig to quote yourself....

I didn't say on the original post, but mine virtually mirrors the mph & rpm all the way from 4,000 (40mph) up to 7,000 & 70mph!  So I was impressed to see the Downtown is only 6,500 rpm for 70mph.  Also, I mentioned the rough patch I had on my XT over 6,500 rpm and, sure enough at 1,800 miles and rising (at last), that rough patch HAS smoothed out.  Not gone completely, but nowhere near as bad as it was.  Need to wait for the mileage to hit about 5K to get the final picture I'm guessing?

  my new downtown 300i in 2012  hade a belt 109/23  30 percent ,  this is new to Canada,  had to wait 6 months for delivery.,  mine was ordered in 2011 ,. rpm at 60 mph  7000 to 7500,  rpm at 70 mph.  over 8 000 rpm,  in Europe people were getting the same as you all,  just the odd one like mine where high rpm.s,.  I started to work on my weights slider rollers,  ended up playing with the variator, carving the slides for the rollers ETC. that improved the rpm a lot, just lately I got a variator for my B V 350  and it looks just like the one I made for my downtown  rpm at 60 mph  5000 to 6000  on a hill,.   70 mph  6000 rpm.   only thing loss of top speed 150 kmph  as it was in to high of a gear so 140 was good for me, it is just to show off anyway very short runs !!!!.,

SPEED first wear a parachute,  to slow you down ,  then get a Malossi variator, and use liter rollers or sliders, to keep RPMs up, I wanted to keep RPMs low for my longer rides ,.
