Fuel economy - Single vs Twin

**aldebaran** · #1 3 Sep 2005

Me again. Was wondering what the difference in fuel economy between the F650 and Trans Alp 600 for instance would be? Would the twin be a lot thirstier?

On tarmac, my F650GS will do more then 25 km on a liter with a peak of 29 km. Pretty good I think.

my 650 transalp does 190 miles on 19 litre tank, would probably do another 10/15 miles before stop, city/motorway

Twin is not that much "thirsdier", just a bit, but also the power difference is big and less vibrations.

For R1150GS the BMW states:

constant 90kph = 4.6 litres per 100 kilometres
constant 120kph = 5.7 litres per 100 kms

my f650 will do up to 200 miles steady riding on the motorway before the warning light comes on. That's 12 litres down and 5 in reserve. Most I've done on reserve is 40 miles before chickening out and filling up - even then I've never got more that 15 litres in - total tank is 17litres and a bit

Thanks guys, you've been an incredible help. Keep up the travelling, we're hoping to do South Africa to France next year, I'll keep in touch.

hi,
i got a 32000km used HeroHonda Karizma (i am in India)
its a 223cc 17bhp single four stroke..
i have toured a lot on it (mostly in himalayas)

at a cruising speed of 85-90kph : 2.6 liters@100kms
at a cruising speed of 95-100kph : 2.9 liters@100kms

the max i have gone on has been a shade under 140kph (speedo)

i am very much in the initial stages of planning a big trip (inter-continent one).. the bike has a 15liters tank (takes in around 16.5liters)

so it should give me a min range of around 585kms/365miles!!
