My absolute best fuel figures were 392k's on 18.34 litres

, or 89k's on reserve fuel

Mind you i was specifically riding for economy :thumbup:
On what bike? Surely not the FZ6?
I've taken 'er to 344kms (just shy of 214mi) and put 18.23L (4.815 US gal) (5.3L/100kms, 18.9km/L or 44.5MPG))
Now, I'm probably heavier than you, but yours seems like incredible economy!
Makes me sorta miss the TDM! (24k/L riding two up over the Cardwell range!)
Now, when I fill up, I take the level in the tank to higher than the bottom of the filler hole (takes a while as it levels out)
So, I don't know how much capacity is left - I think Yamaha rate the tank as holding 19.4 filled to the bottom of the filler neck, so potentially, I could have another 500ml or so!
Any thoughts?
Cheers,
Rick
EDIT: As for the topic of 'how many kms can you go on reserve', I've not tried it past 40kms - so based on a 3.5L reserve, and my mileage of roughtly 18.9km/L means I
could potentially get 66kms - but I don't know if the fuel pump can scavenge every last drop, nor do I want to get off and push, so err on the side of caution.
