Maxwell,

I am not sure if you want more info about the 650GS or from the originator of this thread; in case of the former, try
BMW F650 (UK)

From that site, some detail of fuel consumption:-

The Statistics Fuel

Other than that, there is no "wrong bike" - just different bikes!
Enjoy your XT660, you are just getting to know it!

Yep just getting used to the bike, my daily commute is about 10miles motorway,5miles grid locked town, then another 5 miles 30-40mph roads. Thats only one way so 40miles in total a day. The first time i checked the mpg i was getting about 50mpg, which i thought ok town works bringing it down. Did the same route but took it easy on the old throttle hand and oh 60mpg, and thats still doing traffic riding. So yea maybe 70mpg is possible but not if im riding the back roads home.He he. But i wonder how this would change when fully loaded with alu panniers, topbox, tank+tailpack??

Any way keep her lite.

Well Mollydog, there is no confusion in the statistics given in those fuel figures. All in MPG, i.e. average = 79, after riding at least half way RTW (over 14000 miles).
I wouldn't think that Nigel, being in NZ, is using that tiny gallon that you have in the US either, but he can answer for himself.

As an update on the UK: we have just got a "reprieve" from the EU (God bless them and all who live there ) after years of argument about Imperial measurements.
So, we will be retaining the pint of and pint of milk but continue to buy fuel in litres.
Similarly, we will be using metric measurements for such things as bolts, science and engineering generally but we will continue to ride/drive miles - as you say, those same miles that you guys are still using. Therefore, all of our road signs, such as speed limits, will remain in miles.
Not a problem when going abroad now that those thoughtful Jap manufacturers have given us digital displays which can be changed between Kilometres per hour and Miles per hour at the push of a button.

You will realise that we continue to use the hour/minute/second system of time measurement (i.e. it is, illogically, non-metric, just as Lats and Longs follow the same basic lack of metrication) and we still have the Prime Meridian that passes through Greenwich, London despite the attempts of the French to have their own mapping Meridian (based on Paris of course) as the map reference of choice.
TG, some things never, ever change!!

Interestingly, the author of the fuel statistics slips quite easily between purchases of fuel in litres in local currency, to converting this into;
A. MPG fuel efficiency figures and,
B. a cost comparison, based on the US$.

Fuel Injection: from Jan 08 this is "compulsory" throughout Europe - I believe that is the current situation with some exceptions made for bike models that sell less than 5000 per annum (and the latter maybe a temporary sop to the manufs). I think that is the situation and someone will correct the detail if I am wrong - don't really care, because it is going to happen sooner or later.

Regards,
