My lowest Mileage was about 50mpg, I mostly get above 60.
What are your cruising RPMs and your shift points?
In traffic (at or below 60kph / 40mph) I tend to ride between 5000rpm and 6000rpm. As I accelerate I let it get up to about 6500-7000 and then shift, once I reach my speed I go up until I’m cruising at the above speed.
Going any faster and I find the engine doesn’t like being below 6000rpm, so I cruise at 6000-7000 and accelerate with shifts happening between 7000 and 8000. Of course, if I’m feeling a little quicker I’ll hold off shifting until 9k-11k.
I’ve got a slightly different engine than you (tuned for a bit more top end power at the expense of mid range torque) but I think our shifting should be very similar. The newer 250Rs can probably get away with a bit lower cruising rpms.
