Fuel economy - bikes

Something crossed my mind this morning as I rode to work.

Back when it was dark and cold, the Diavel was getting 6.5l/100, and spend most of it's time in 4th-6th with minimal throttle openings.

Now it's warm and dry (apart from the easter weekend, of course ), I'm riding in a somewhat more 'committed' fashion; this means 3rd & 4th gear on the same route as above, and - ahem - wider throttle openings and more rpm. Yet I'm still getting 7.0l/100.

How so? Given my increased pace, I should be getting a lot worse surely? (eg: last trackday was 10.5l/100).

Re: Fuel economy - bikes

You are running the throttle and RPMs in the right gears to get the best fuel economy. Letting the thing run at 1000rpm in a 30 is not the most efficient for the bike....

Oh and it's warmer outside so the temperatures allow the bike to run more efficiently.

Sorry "double O" - although I agree with the first para., the opposite is actually true of the last bit.

Petrol engines prefer colder weather.

I tend to agree with this - mine runs 'stronger' in cold air. And it's a modern bike too, so shows it works for fuel injection as well as carbs.
