Petrol consumption? 2004 GSX, 2007 GPX, GT250R, Ninja 08

[glice]

btw, I'm doing a hot trip to welly this weekend. I'm gunna bash this piss outa it and see how BAD I can get the fuel economy, without killing myself in the process. Uh, yeah, itsa 650, and this is a 250 thread, my bad.

get on a track, thats how I got my worst fuel economy.

But those economy figures from those modern bikes is probably starting to really kill the value of bikes such as mine

maby you could do with a tune, my almost 20yr old cbr gets almost the same as totos hyobang

Interesting thread.
Funny that fuel consumption if never specified in the spec's sheets...

anyways...

My 99' bandit 250vvt gets 200-240k's out of a tank. (about 11-11.5 liters)
so about 5-5.5 l/100k or circa 70 mpg (US).

here's a good calculator:
http://www.minirepository.com/fuel-consumption/

can we please agree on common fuel consumption/economy unit ?
mpg (US or UK), l/100k (european standard) or even km/l, but please NO 'kiwi standard' xx km for $yy....

So anywas... fuel consumption (esp with relation to bikes) is greatly affected by:
-type of engine (4 pot or 2 pot)
-gearing (engine rpm @ cruise speeds)
-how fast you accelerate, often reffered to 'style of riding'
-your FE (fuel efficiency) skills
-how and where you often ride (long/short trips, mainly motorways or mainly 50kph zone, flat or hilly terrain)

if you think 70mpg for a bike is good... I regularly get better than 60mpg in my 20 year old station wagon corolla...

thing is that bike engines are not made for efficiency... while car engines are. small cars are more fuel efficient than large bikes. typical z1000 kawa will get 40 mpg. generally speaking 4 pot bikes will be tragic in terms of fuel efficiency. even small 250cc 4 pots.... because those engines are high strung, wild cams, short stroke, insane gearing... v-twins are better. Carbs are bad too, esp on bikes where cardb's are pretty crude and not designed for emisions/fuel economy. most of them just have idle jet and main jet that just dumps fuel down the intake runners.

but generally speaking all those 'fast' 1000cc 4 pots will get around 40mpg ~7l/100km, injected or carbed... V's will get slightly less. smaller 2 pots esp injected are more efficient like that bmw 650 or hyosung or vtr250 or sv650. that bmw 650 is twin spark i believe (bonus for fuel economy).

I have been monitoring my fuel consumption since day one as this has been one of the main reasons for getting two wheels ... the Hyo is a huge improvement on my twin turbo gas guzzling cage.

On average, I fill up with 13.5L of fuel and can travel an average of 386kms before I am back to 'one red brick' on the fuel gauge. This equates to an average of 28.9km/L or 3.66L/100km.

I am very impressed and will keep monitoring to see if this changes over time.

Cheers DJ

3.66L/100km is pretty damn good... there is no production vehicles (2 or 4 wheels) that get much better than that. ok, modern well built 50cc scooter will get less than 3L/100km, but that's hardly any improvement over hyo...

i'll be interested to know how much vtr250 gets...

v8 driven 'with spirit' will take 15-20 L/100km and those large SUV's get similar or more...

Getting roughly 23km/L on my GPX, (mostly commuting as of late)

I did try to find out the other day, how much I could get to a tank if I was being really conservate with my riding.... lasted about 10km before I was bored as hell, though "screw this I ride for the love and freedom of it, not fuel consumption" back to riding her like a dirty whore *hard'n'fast*

Ha, funny I was going to do that last week as well on my gpx and lasted about the same. Think it is to do with the lack of wind at low speeds as on a longer ride as I find anything over 110km/hr makes the bike more comfortable (I can stay on it for 300km without getting off at that speed but sit on 100 and the body aches a bit.)

I get 300-320 km out of the 15L which is full to reserve (18L tank). That is full throttle acceleration most of the time and sitting around the 115 km/hr mark on the open road.

Have got 350km from 15L when I did a slower group ride a while back but killed my butt and back.

this is for a hyosung gt250r....am i geeky for doing this??

I'm only getting 18km/L on my GPX, or 5.6 L/100km. In other words I do 270km to the 15L tank. Sounds like I need a tune up or something! Once again, I mostly commute at the moment, but I'm not gentle with the twist of the wrist when I get the chance!

[CB ARGH]

Though with the weight of the fuel (okay I'm being picky), if you're able to go such a distance with a 17L talk on the Hyo, why not just give it a half tank to reduce the weight of the ride? It's just another eftpos transaction, plus you could do with a visit to the sh*tter every so often

I'm looking into buying one of these Hyo's, they look really nice, and after a few month's saving, I reckon I could be riding one of these beasts

Yes you are

My dad was an accountant and he does it for his car

[portokiwi]

I just ride and fill up at the end of each week. Crap now with another fuel rise might have to switch of the motor going down hill to save fuel.
My fuel gauge is crazy it has a mind of its own. most of the time says it on empty lol. go to refuel and only put in $5.00 to fill it.

[Roki_nz]

Got about 330-350 from and 02 gsx

[mnkyboy]

On my 250 I get 185kms before reserve (11l) and if i really stretch it out 235kms before I'm almost out.

Saying that I give it death most of the time, and me and my bike are large and heavy

[waitoa485]

i'd be interested to know what speeds you do to get that sort of milelage. I have a hyo comet gt250 naked. I ride 120km a day mon-fri to get to work and back. I cruise at 100km/h on the open road from hamilton to waitoa and get about 450 km from a full tank (17 liters). When I see the trip meter getting around the 400km plus mark I know it's time to start thinking about filling up. Already ran out of gas once! won't be making that mistake again. Mind you the trip meter was reading 470 km then. Great bike although now i wish i had bought the sports version with the fairings! I'm seriouly contemplating moving up to the ninja 650r.

Mate if you only cruise at 100km/hr and use the bike mostly for commuting (would think weekend rides wouldn't be a priority with the 600km a week you do already) then I would say what you have is probably one of the best bikes you could have for the job.

You can get Givi screens for those bike that would help heaps for winter commuting and look ok. The faired hyo has the lower handle bars like a sports bike so not sure if its as comfortable as your model.

650 ninja will get about 375 from 17 litres and does have your bikes riding position with its more upright bars.
