gmaslin Posted July 30, 2017 Share Posted July 30, 2017 In what year did Yamaha introduce engine (speed) modes to the YZF R1? What is the expected gas mileage in the weakest power mode? Which is the most efficient mode for street riding/highway cruising? 1 Link to comment Share on other sites More sharing options...
slice Posted July 30, 2017 Share Posted July 30, 2017 This is the sort of thing it would be best to ask Yamaha UK about, tech specs like this are rarely easy to find without extensive research and comparisons to different models which could take hours of searching. Good luck in your hunt for info tho. 1 Link to comment Share on other sites More sharing options...
Moderator Cynic Posted July 30, 2017 Moderator Share Posted July 30, 2017 Not sure why your asking. The lowest power mode will be no different to full power cruising. It wont change the mixture. Just how aggresive the fueling is. Part throttle cruise is part throttle cruise. 1 Link to comment Share on other sites More sharing options...
