 Posted: 16:04 - 03 Dec 2014 Post subject: Riding super economically. |
 |
|
So perhaps it's a little bit "closing the stable door after the horse has bolted", but in an attempt to save what's left of my licence (after I no doubt get raped for my little kitten killing rampage the other month), I've been trying my best to follow the posted speed limits.
As a side effect, and with little conscious effort, my MPG has gone from ~40 up to 48 measured by litres in vs miles done rather than any fancy onboard wizardry. This has given me a new high number to aim for, since high MPH's are so frowned upon. Can I break that 50mpg barrier? How about 60? My commute is fairly consistent, It's basically filtering for about 70% of the 22.5 mile journey. It's pretty identical in both directions.
So far I've been trying to change gear at 3krpm, and keep my top speed to 50mph. I'm not really sure that this is the best way to ride economically though?
So. What are your top tips for bringing my MPG up? What sort of gains can I expect to see? If I was to hit 60MPG I'd need to crack an extra 55 miles out of a tank (bringing it up to 257 miles from 19.5 litres), is this even possible without doing a whole tank on the motorway? ____________________ I am a bellend, I am a man of constant sorrow, I am a gummy bear, I am a rock. |

Make sure your tyre pressures are sorted first of all. Apparently new engine oil and a serviced bike can add up to 5% towards MPG, this could of course be manufacturer's BS but likely some truth in it.
Then when it comes to riding, just try to predict everything.
I generally always try to never come to a complete stop, in slow moving traffic I move slow, (car) off the throttle as opposed to accelerate > brake > accelerate > brake like most of the mongrels on the M25.
As you said, just nice smooth changes relatively low down in the RPM's. Smoothness is the key IMO, and keeping moving, starting from a stop soon adds up moving all that weight.
Also on a bike aerodynamics can play a big part I seem to remember. Get your chin on that bar!
The only other thing I can think of is going downhill for long sections, apparently putting the bike in neutral can use more fuel than putting it in the highest gear and just not touching the throttle, so just do what works for you. Sometimes I like the speed increase from neutral..

74mpg from my NTV600 over a 200mile journey on A roads and Dual carriageways. That was fully fuelled up and with full luggage. Not bad for a 300quid shed with pod filters, larger carbs and a bodged up exhaust system!
I just keep the revs below 4000 on that bike.
My ZRX11 can manage 50mpg when revs are kept below 4000 also. But its boring as hell and I might aswell just ride the NTV.
Just dont let the engine labour/struggle and be smooth on the controls. ____________________ Suzuki GT250 x7------- Fazer 600------CB250RS------Aprilia Rally 70----- Bandit 600

Buy a Honda C90... Even ragging the tits off it everywhere sees 100 miles to a tank. That tank only holda bout 3.8 litres
Limited speed though haha! Your never gunna lose your license on one! And they are rather easy to wheelie (Unintentionally!) ____________________ A2 Passed 18/6/10 |

Maybe change the sprockets? I can't remember which way you go but it means higher speed for lower RPM at the cost of bad acceleration. ____________________ Spain 2008France 2007Big one 2009 We all die.

Clutch in as much as possible. Roll without power at every opportunity. I've had some really good MPG figures.
66 out of a Bandit 1200 (with 91,000 on the motor). 127mpg out of my RXS (average is about 75, maybe 80). 164mpg out of a CBF125 recently. But these were under perfect conditions. Remember getting over 90 out of a GPZ500 a few years back too, but again, in perfect conditions.

Sign up with Fuelly or at least have a look at the results other people are getting with the same bike as you.
I love this sort of thing because I can really get my nerd on. I wrote myself an app so I can keep track of it all without relying on fuelly (although I post there also automatically from the app as a backup).
I need to tweak my graph code a little bit, not quite right but if gives the general idea. I also keep track of miles/ per fill up and the price of petrol.
Best I've had so far is 77.7mpg, that was on bikesafe
66.7 was when I was on the A14 for what felt like forever....
I'm fairly consistently using 11 litres for 200 miles, about 3 left in tank. I could push it a little more but there's a petrol station at either end of my commute and sometimes it's just easier to fill up when the last bar starts flashing.

When the engine is idling (clutch in), it's still using fuel in order to not stall. If you have zero throttle applied, and are still in gear, then the engine is using ZERO fuel. So, lift off early and use engine braking before corners/traffic lights etc. If it's good enough for F1 drivers to save fuel, then it'll work for you too.
Acceleration is the real killer of MPG - going 50mph instead of 60mph won't make much difference, but braking means you then have to use extra energy to get back up to speed. If you can maintain a constant speed you'll get better mpg, so plan far, far ahead, choose routes with no traffic lights, and so on. ____________________ 00 Honda VFR800 | 09 Aprilia Tuono Factory

Gains might not be as much as you'd think. Ok, if you are coasting down a long hill that you have to stop at the bottom then having a system where fuel is shut off at closed throttle you save every bit of fuel that isn't injected but if you have are driving along and want to keep an average speed then shutting the throttle will save you fuel but the rate of decline is greater because you're dragging the engine along so you'll need to get on the power sooner to maintain a decent speed. In this case, you might find a better saving having a bike that you can hit the kill switch AND pull in the clutch so you're using no fuel and not dragging the engine along. I sometimes do it. I know I can get 4 days of commuting out of a tankful but if I have to make a detour it gets a bit dicey. If I go on to reserve before the end of my 3rd day's commute I'll save a bit of fuel on the last day by coasting on stretches where I need no power. Can save probably 20% of my fuel if I'm careful/can be bothered. ____________________ a.k.a 'Geri'
