Fuel Consumption

[TeaPig]

Temperature does affect the fuel consumption. My 1150 would routinely do about 30miles fewer per tank in the middle of winter compared to a really hot summer. The 1200s seem less affected though and there's no way the cold alone should drop consumption down to 40 mpg

My 2011 GSA averages 41mpg according to the OBC. I've done a couple of tank-to-tank checks which confirm the OBC is just about on the money.

Very little Motorway or heavy traffic though.

I'm not talking about atmospheric temperature - I'm talking about engine temperature. If the engine control unit thinks the engine is still cold it will try to deliver a richer mixture and that make a huge difference - ever had a sticky choke cable on an 1150 ;-)

Depends on the distance your doing in cold weather. It's well known that trips of under 20 miles in cold weather has a big effective on fuel consumption. The engine takes far longer to heat so it uses more fuel during that time. I would imagine an aircooled bike would show this even more because it doesn't have any real temperature control so will take even longer to heat. I get about 50 mles less range on the bike when it's cold, I loose about 80 miles from the car as well. I tend to do a lot more short trips in the winter as well especially on the bike.

2008 gsa

21000 miles did 370 miles 2 up fully loaded in italy last year all sorts of roads inc passes no fuel warning light, now at home 1 up in very cold weather filling up around 285-300 thats when the orange warning triangle comes on, Computer says its doing between 41-43 mpg not great but better than my car putting between 29-30l in at every fill, even managed 32l once.

Does you can make you feel as alive as your bike?
