Best fuel consumption 125cc

[larks]

Looking for a 125 that I don't have to fill up too often. Scooter or bike, but probably bike. Any advice welcome.

[Polarbear]

I would guess the 4 strokes 125'sare all as frugal as the resultant offspring of a Jock and a Yorkie. Not much in it whichever you go for.

How often you have to fill rather than how much it costs to fill? The one with the biggest tank size!

Oh, you are going to get Teffed so hard.

As above, any 4 stroke 125. You'll see 100mpg from even the crustiest carbed hack, up to 130mpg from something like an MSX 125.

Pick anything in your budget with the biggest tank, leaning towards Japanese branded if possible, enjoy. Don't over think it, there's no perfect bike.

I guess I was hoping on advice on the biggest tank size without having to trawl through every potential model and find out the tank size...

Most 125 bikes are about 13 litres. Most 125 scooters are about half of that. How far you'll actually get will depend more on the usable rather than notional fuel in the tank, your right wrist, and your tolerance for risk / willingness to push it to a petrol station. Figure about 200 miles for a bike, 100 for a scooter, which is pretty good going compared to bigger engine bikes.

The Varadero 125 has 17.5 litres, and is generally recommended if you can find a good one. The youngest one out there is 9 years old by now though, so it's becoming less likely.

100mpg is a starting point. My (Moto GP) 125 scooter just seems to sip fuel.

My little CG uses so little fuel and I use it for such short journeys that i keep forgetting that I have to put some in occasionally. I've run out about 4 times in the last year. It has no gauge or resettable milage display. Thanks k fuck for the reserve option.

The modern injected bikes are even better.

I noticed that as well. I saw 2 in Edinburgh brand new but they were expensive.

My fuel injected YBR125 averaged a genuine 110mpg without any effort, and that's commuting in central London.

If highest mpg is the most important criteria then forget bikes and buy a Honda PCX 125 with stop start system as std. These always seem to do over 120mpg, but can do 130mpg in some conditions.

I don't know much about high mpg 125's these days, but I'm happy to recommend several 125's in the 35-40mpg area.

[Rogerborg]

OP seems to want tank range, which is something that I agree with. It was a hassle filling my 11L Burgman 400 so often, especially with the location of the filler.

Why is tank range so important?
I mean.. it's usually my numb arse telling me I have gone too-far on the 125 long-long-before I'm starting to fret that petrol stations seem to be a bit thin on the ground...

I once put my R125 to the test.

Rode very gently and kept the revs low after filling it up.

Can't remember the exact milage I got from the tank but, it was between 280-300 miles before I bottled it and filled up at the next garage.

Tbh, the one thing that pi$$es me off about riding a big boys bike, is the amount of times I have to refuel. Last time I checked, I was getting around 34.5 mpg from the er6f.

I've done probably almost 45miles running in on 4.7L of fuel on a 125, but it could hold almost 9L if I could work out how many Slippery synthetic Esters that would need?

I do have a vague recollection of beating the hell out of a CG125 decades ago, and it doing over 200miles and still not touching reserve. What were they a 14L tank?

Shaft won't like this, but out of everything I've owned capacity for capacity, scooters were the worst on fuel, not just tank range. Those expanding belts absorb an awful lot of power that the rear wheel never sees, as does running constant rpm on acceleration.

Book says my 125 augt return something like 100mph. Same book, says my 750, should only return 50.
750's tank, is relatively large, holds 4.2 imperial galleons.
125's is also relatively large, for a tiddler; holds a claimed 3.7 Imperial sloops....
In theory, the 750 should give a range of about 200 miles, the 125 a range of almost 400 miles....
In PRACTICE... means squat!
Round town, neither return anywhere close to what the book says they should... depends on right wrist, frustration, trappic light GP's and road-works.....
Out of town...... it STILL depends on the right wrist, T-Junction GP's and road-works! Oh... and what mood I am in! Which is probably the more pertinant.
The 125 gets thrashed mercilessly.... that's why I keep one about! Ride the 750 like I hooligan... and I probably wouldn't end up dead... just give myself a hernia trying! 125, begs to be caned to get anything out of it, and conveniently can deliver almost all it has without breaking too many speed limits along the way.... or my small intestine!
Consequently, I tend to get worse than book from the 125, and better than book from the 750... and they BOTH average out at around 70mpg... the 125 being thrashed, the 750 tending to be used on longer runs, in rather more laid-back manner......

MEANS.... err, well there's half a clipper difference between the quoted tank size of either.... and both will be running onto reserve at around 200-250 miles.....

For where you are quibbling... well, AFAIR the MT07 has a peculiarly small tank to begin with 14liters.. what's that in English,. err... 4.5 Napoleons to a galleon... err... 2 and a half gallons, ish? Fuel winjected, it probably dont have a reserve, just an anoying lamp that blinks on the fuel guage when it gets 'low' set to come on rather concervatively not a lot beneath half full...... assuming you dont ride for best mpg, and you stuffer the sitty-snarl, what, 50ish mpg? You probably have that lamp pigging you off in around 60-70 miles from jazza... slopping over the filler cap on the fore-court..... sort of suggests a longer commute, if you have to fill every day.... b-u-t....

The issue of tank-size, probably ISN'T that much of a big deal in the greater scheme of stuff..... neither is book quoted MPG... it comes down to how you use it, and whether you get even anywhere close to that book quoted MPG, and the range of the quoted tank-size down to your tolerence for blinking lamps, and natural parania levels..... A-N-D you will probably not find a different bike, inherently solves the problem.....

For every-day commuter.... the apparently high MPG of a 125 does look good... but I rarely get it..... and get as good from a big bike I dont feel compelled to thrash as hard.... larger tank-size, for greater range, then becomes a little less critical, and how often you have to fill up... the 'REAL' issue here, it seems.... is something you either live with.... or not. Move closer to work, get a job closer to where you live, let a bus-driver worry about the fill-ups at the depot, sort of thing.

How long does it take to fill up?

Maybe 10 minutes a day, it could rather dent the time savings you expect and probably dont see taking the bike, wheretogging up either end, eats another chunk of unpaid life.... B-U-T is that less than an hour a week, more of less wasted filling a bike with fuel, than waiting for the wrong bus to turn up, or the boss to moan about your helmet hair or the puddles under your wet-weathers on the back of the door?!?!? And how much time 'really' is that compared to other 'routine maintenance' like checking the oil level, and the other stuff you probably dont, but probably should, do, like cleaning the lamps and number-plate, or de-icing the speedo on a frosty morning?

All needs putting into context, not looking at under the microscope..

THEN, is a smaller bike, with a notional and oft only presumed bigger tank and tank range, really a solution to much if anything, or just a different mix to the compromise?
