I don't think R3 was planned as a mpg effecient commuter.The r3 can overtake in 6th gear means it's hopelessly undergeared for day to day use.
It's geared lower than most 250cc bikes, acceleration at cost of mpg.
I've been looking at that, and for me to get normal acceleration out of the R3 will be very hard.
Upgear by 50% seems necessary, which is quite a lot.
The cbr can have acceleration in top gear, when you'd downgear it.
But then you won't have the top speed, because of its lower rev limit, nor the mpg.
I realize that.I don't think R3 was planned as a mpg effecient commuter.
Suzuki GW250, on the hand, is exactly that - fuel saving, somewhat boring dynamics bike.
