Default fuel costs

I've been looking about at bikes between a 250 up to 600cc I'd be mostly useing it for work about 25 miles each way and then a few spins from Dublin to Carlow about 50 miles ones way would a 250 make that handy or would I need more power to make it comfy spin and fuel cost is their a huge difference between 250 or a 400

Motorbike: 2017 s1000rr
Modifications: brakes, pipes
Default Re: fuel costs

My s1000rr does 55 mpg anywhere from 40-90mph

But no there shouldn't be a massive difference

Fuel consumption isn't always proportional to engine capacity.
Some of the more efficient bikes like the Honda NC750 will
be as good as or better than a typical 250-400cc bike.

Some real world examples here:

The default setting is for US units.

Beat me to it - the Honda NC / NX bikes seem to have more of a cage engine (lower rpm) and excellent MPG figures.

Default Re: fuel costs

best mpg i ever got was a zzr1100, worst fuel economy was my hornet 250.... hornet was high up in the rpm most of the time commuting around the zzr was at 4k when i was commuting, not all about engine size as said before. if you find something that does a steady speed that you like at a low rpm you'll get good mpg.

It's far more proportional to power output than engine capacity. Except in the case of Harleys, which have an uncanny ability to convert fuel and air into noise, without the added side-effect of power.

My Pan European uses about the same amount of fuel as my CD200 benly. There's a lot more to it than engine size.

Motorbike: Yamaha XSR 700, Yamaha R1
Default Re: fuel costs

Best to look at the data for the bike.

My old bike was a Ducati S2R 800
My current bike is a Yamaha XSR700

Both have basically the same power output (about 75-80 bhp)

The XSR gets way better mileage.

Ducati gets 130km to a tank
Yamaha gets 200km to a tank

Same size tank.

Even my R1 gets better mileage to the Monster.

As people have said, the Honda NC700/750 is designed for fuel economy so it has great figures. I just refuse to drive a bike with that little bhp :)

corrected

Best MPG I got was from the most powerful bike I have
my FJR1300 around 48-50 MPG
ZRX1200 around 45 MPG
KTM 990 around 35MPG and that's using premium

Combination of aerodynamics and torque/RPM is a big factor

I have an FJR 1300. It has approximately the same power as a wet fart

The long-term average for my ZZR1100 is just under 49 MPG.

Generally in the 40s around town and 50s on longer runs.
I have seen 60+ MPG on longer non-motorway runs.

Details on Fuelly. Default unit is US gallons.
