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 !!!!.,
