I do 60 miles a day up and down the A13 on a CBF125, with the tall screen and have little trouble. 120mpg goodness.  |

Well lets put it like this.
In the last 6 years, I have had a GN 250, a ZZR 250.
I then changed to a XJ600, now have a Versys. All main use is commuting.
MPG has been better on both D6 and V
Ins was cheaper on the D6 when I changed from the 250.
Personally I found that the 250's while Ok for commuting lacked the stability that a larger bike provides. And when you have low set bars, commutting is a real pain on the wrists. ____________________ Just because my bike was A DIVVY, does not mean i am...... |

I commute on a GPz 305, which should have fairly similar performance characteristics to a modern 250. I'm surprised that the GT250R only has 21kW and 5 gears though, I'd have expected it to be knocking on the 25kW limit.
I find the performance sufficient for my needs. It'll keep up with traffic, hold a real 70, and win the traffic light drag race easily enough.
Fuel, eh, I don't really keep track of it, but I think it's in the ballpark with the Hyosung's claimed 80mpg at 55mph-ish. It does want filling more often though when used for fun. Making Progress or motorway speeds require keeping a lot of throttle on, which possibly negates the benefit of a smaller engine.
Have you tried lengthening the gearing on your ER-5? And I'd expect a screen, even a tall one, to offer more streamlined wind resistance than a clothed body. Or you could ride nekkid and oiled up. ____________________ Biking is 1/20th as dangerous as horse riding.

Standard gearing and tyres on my GPZ500 (2002)
in 6th, 50mph is ~4k rpm and 40mph is ~ 3krpm
I vary the speed depending on the road / weather. On hilly roads, I usually hit the hill at 3.5k rpm and lock the throttle in that position. Just as I hit the brow of the hill, the revs have dropped to 3k rpm. Going down the hill they gradually increase to 3.5 again.
If its a windy day, I aim to stay at 3.5k rpm, going up to 4k if I hit a hill and the wind is against me. As before, the revs will gradually drop when going up the hill resulting in 3k at the brow.
On the flat, my revs are around 3.5k rpm.
I try not to go below 3krpm as it can lug the engine.
I keep track of my MPG online here:

If my searches for a 250 are any thing to go by, I say "good luck" for trying to find a decent 250 that`s not at a rip-off price .
I`ve been looking for about two months now, for a 250 and every man and his dog wants stupid money for them?
I`ve even been looking for a tatty but viable "project?" bike and even those are silly money
I could pick up a 400, or a 500 at a better price than the 250`s i`ve been looking at  ____________________ I am the sum total of my own existence, what went before makes me who I am now! |

Not up on the fuel consumption but swapping an ER5 for a Hyosung is a step backwards IMHO.
Commuted on an ER5 for 5 years until some git ran it over. Funnily
enough commuted from Basildon up the A13 to West End in 2009 and 2010 on a bandit though. Although the bandit was fine, not quite as easy to throw around in the traffic as the ER5.

A slight distraction but... when doing my CBT the instructor had a 250, he dropped what I thought was an interesting comment, 'why would want anything bigger', I didn't ask him to justify that but I think if you get anal about speed limits etc, he may have a point?
I commute 110 miles daily return currently by car - 50 motorway, 50 A road and 10 B road and have been asking myself the same question
My problem though is also related to my tender 20 stone weight
ER5 is what I want when I grow up  ____________________ Knowledge is knowing a tomato is a fruit. Wisdom is not putting it in a fruitsalad!

Well lets see..
Your 250 doing is always going to be floged to death on M'way, pretty much the same on the rest as well as you have to work the engine/gearbox a lot harder to keep pace.
Compare that to a 600. Where 70 in top will be 3 to 4 K. Not even taxing the motor at all. Mine would pull from 2K all the way to red line if needed.
Oh and i spent most of my life on 250's as I not that big.
Only after getting a 600 did I realise how less stressed a ride they are. ____________________ Just because my bike was A DIVVY, does not mean i am...... |

This is seriously impressive. I wish my Bros did that kind of economy. It does a max of 65mpg, and I suspect if I sorted out the carbs it would do 70-75. But 90!?

Must admit I've been reading this post with interest, years ago I used to commute into london on a FS1E then 250X7 and XL185 . All by the way doing the job required , and yes theres a change in riding speeds ext ext but on fuel the little 50cc ran on a damp rag but could only poodle along at 30-40mph . Clearly the others could hussle nearer the max limits and the fuel is not going to be quite the same. I think that being in the position that I don't have to commute and the 1200 is purely for pleasure, I would go for a 4-500 and trickle along so keeping the economy where you need it , I've had the pleasure of riding various bikes over the years and have found that it normaly works better when the motors are not strugling . Compromize is where your at and the one thing I would say is, the Chinese bikes are not really well known for there longevity and not that reliable if they don't fall apart so good luck and hope you get it sorted . |
