Re: Mpg

I felt like proving a point, whether or not the guy is full of it. I know the best way I can get the best mileage is do the regular maintenance on time, ride efficient, and lose weight, and just ride.

Previous owner told me he got 70-75mpg on my bike and he was probably around 180-195 pounds. I weigh 240 and my commute is more on the 45-55mph end than his was. I have been riding as low as 35mph but mainly 40-45mph in 5th gear at around 4,000-4,500 rpms steady.

Re: Mpg

Yeah, that guy was just a straight up:


You might actually be not in the most efficient drive mode if you're cruising around at 45 in 5th at your weight.
Toy with it and see which one is better. If you're having to roll on in 5th from lower speeds, you're just wasting fuel trying to get back up to cruising speed.

70-75 mpg is a big claim. I'm a slender dude and I was getting 63-68 like clockwork - new bike and wrenched by my own hand - and I would even down engine off coasting (EOC) and shut down the bike at train crossings or longer red lights.

Re: Mpg

I'm trying consistant riding each week. Though its getting too cold for me now at night 60F windchill. I wear long sleeve shirt, hoodie and jacket to keep warm.

Lucky for me on my route there is very little traffic, so its not a problem to maintain speed in 5th. I'm watching my rpms and throttle and gears I do.

I hyper mile too, just not too often just at that pesky railroad crossing that gets me. Once someone is behind me I turn it off and lights off too to keep battery up. I try to get behind a truck or van and get a boost, but not tail gating.
There is no point for the engine to be on if you are just coming to a stop. Other than keeping the headlight on and battery charged.
By next riding season I'll be trying hypermiling techniques to get the best mileage. But for now I'm experimenting to see what just changing riding styles.

Re: Mpg

To stay warm you need something that's wind proof. Hoodie's, shirts, and most jackets just aren't going to do it.
At the very least you need an underlayer that is breathable and then top that with something wind proof if you don't want to splurge on a weather proof outer layer. (The good ones are expensive.)

Another option would be a pull over top layer that is windproof - they're basically big rain jackets but they cinch at the waist, neck, and wrists.

Re: Mpg

I've been shifting around 4,600-5,200 rpms and tend to cruise around 4,000rpms in most gears. I ride at constant speeds for miles all along the 20+ miles to commute to work.

Highest I go is 55-60mph on the 55mph highway at 5,200-5,500 or so rpms.
But usually I hang 5,200 rpms on 55mph roads.
On 45mph roads I stay in 5th around 4,000-4,500 rpms
35mph roads I'm in 4th gear around 4,000-4,500
Lowest I've noticed the rpms where the gear struggles is around 3,500 or less.
I filled up and got 65mpg for the 2nd tank in a row! So this is pretty damn good as it is but I like to know if I decide to ride more aggressive and riding faster.
I have the 16t sprocket.


Just wondering what others rpms were usually? I use a digital tachometer/hour meter

Re: Mpg

My second tank I got 65mpg again.
After that I did a couple days accelerating quick and revving 6000 rpms in a gear to feel more pull of the gears. 3rd gear before 50mpg at 8000rpms now its closer to 60mph.
4th is the gear to be in on the highway to maintain 65-70mph easy.
Instead of riding in 5th at 40-45mph I was in 4th.
Main difference was cruising in the 5 or 6 thousands instead of 4 to 4,500rpms
That all got me 56mpg
Did that for 90 miles. Not doing that anymore, if I wanted quick and fast I would have gotten an uncomfortable Ninja. Back to casual riding 65mpg is better. No need to be in a hurry.

Re: Mpg

I'm getting about 84 mpg using midgrade octane and always use Strar Brite fuel conditioner. I do baby it and don't rev too high during shfting. As of late, I've startedreving out longer.

Re: Mpg

Sounds as though you've got a really weak mixture. I ride like a little old lady (most of the speed limits are 30 MPH, here) and I get about 65 miles to the American gallon, with the bike set up, from the factory, in European mode, ie richer mixture.

Re: Mpg

what is it to the (guessing) imperial gallon. that would be more of a brittish unit for gallons. I don't think there are Spanish gallons.

When you go to the gas pump, or petrol pump, are the units in liters?

I wish sometimes in America we all just used metric, in science measurements are in metric. It's a lot easier going by multiples of tens and using root words. At my job when I took my wastewater class 4 and class 3 licenses, I had to do lots of conversions on the exams to find "how many pounds of ____ are dissolved in a 24 mg/L of the sample came from a 10,000 gallon tank".

Stuff like that where it would just be easier just to say mg/L in the sample and you need to find out kilograms of substance from the 380,000 liter tank. I might have something wrong but its just to give you an idea of how more complicated things get because of different measurements.

Instead of what we grow up with mainly learning 12inches = 1 foot 5,280 feet = 1 mile
Then learning conversions about 2.2 pounds is = 1 kilogram
I use metric much more than "standard" that when I work on US stuff I kind of dread figuring out the right sockets to use ( oh 5/16" is too big gotta try the 1/4" ) Rather than oh the 8mm is too big I need a 7mm
Now I still prefer mph to kph I guess that's what I grew up being used to.
But I like mm sockets in whole numbers than inches in fractions.
kpl or kilometers per liter would have to be much larger numbers as compared to mpg's

What I'm getting back to, is what do Spanish or other countries people go by?
Obviously I know America uses standard mainly and everywhere else uses metric mainly
