I'm from the other side of the globe based in New Zealand and I own a 2016/17 vegas pearl white 1330 RT and whilst fuel economy is not a major concern, it still is a topic that I am interested in. I saw in the sales info that BRP claimed a fuel range of 250miles (400Kms), this was a welcomed feature from my previous RS Spyder, but unfortunately it doesn't seem to pan out that way. The best I have achieved is 200 miles with no bars showing and the fuel light on. I ride with a friend who owns a 2015 F3 which has the same engine and what I believe is the same capacity fuel tank and he consistently obtains 250mile + range, and that's when we are riding and cruising together. Admittedly the RT is pushing a little more surface wind area and possibly carrying more weight, but I thought not at the expense of 50+miles in range. I talked to our local dealer and he said that the fuel mapping maybe different between the bikes with the RT producing torque lower down, I however struggle with this as you would have thought if the torque was being produced at presumably mid range cruising speeds, then it would be more fuel efficient. He then went on to say that maybe we could remap the fuel system accordingly, but when I spoke to the mechanics about this, they were reluctant to consider this. ( I think that this type of work was beyond their capabilities anyway). It would be interesting to talk with the BRP gurus around this subject, whether there is any truth in different torque curves between the RT and F3, but I am having trouble finding the right people and addresses to ask about this. The cost of fuel over here is worth mentioning as we are paying $2:30 per Litre, so I understand that a US gallon is 3.9L, thus a gallon is worth $8:97. Would anybody know of a subject matter expert in this field that I could at least chew the fat with so to speak...…..Morris Jones
