I looked into fitting an RS tank on a 2014 DLX and was told the tank will fit; however, the filer cap is different and requires a second key.

And yes, that gold RS is hot!!! Very congruent look with the forks and shocks!

i want a 2017 gas tank real bad too...
just so I can paint it -exactly LIKE THIS~!

That gold color really shows off the curves around the knee area.

That bike is gorgeous Heart Smile Cool

It's worse than that Sad

Unlike an automobile which is these days carefully designed for aerodynamic performance, a motorcycle uses most of its generated power to overcome the resistance of the fluid that we travel in. (Car drivers generally have no idea that they actually travel though a fluid Smile

The fluid resistance (and the amount of fuel we need to burn to overcome it) is not proportional to the velocity we travel at, it is proportional to the square of the velocity.

Which is why when we are afraid to run out of juice in a car, we drive in as low revolutions as the highest gear will let us do, while on a motorcycle we travel as slow as we can without being a danger to ourselves and those we share the road with.

True. And with their smaller fuel tanks the aerodynamic drag penalties can make themselves quite a bit more noticeable on a bike. Particularly out here in the west, where there can be long distances between gas stations.

Although my CB1100 routinely delivers about 45 mpg at 75 mph Interstate speeds, riding into a 25 mile headwind can drop the fuel consumption close to 35 mpg. As far as the bike is concerned, it thinks you're riding at a steady 100 mph and burns fuel accordingly. All that extra fuel is going towards overcoming the increased wind resistance.

I first learned this years ago on the first leg of a long trip on my old KZ. My first stop was 135 miles away in Flagstaff, which was easily within range of the bike. I rode blissfully ignorant into a 25-30 mph gusty headwind. About 30 miles from my destination, I surprisingly had to switch to reserve. As the reason for the increased fuel burn became evident, I ended up riding along the shoulder at 30 mph in order to make it on the 1/2 gallon I had left in reserve.

The fluid resistance (and the amount of fuel we need to burn to overcome it) is not proportional to the velocity we travel at, it is proportional to the square of the velocity.

It's even worse than that!

The *force* to overcome drag is proportional to the square of the veolocity. That's right. The *power* required (or energy per second, or fuel burnt per second) is the force times the veolocity, which means the fuel burnt (per second) is proportional to the cube of the velocity.

But then again, if you go faster, you spend less time... so fuel burnt per second is proportional to the cube of speed, but fuel burnt per mile is proportional to the square of speed.

Most people plan their stops in terms of range ("I shall stop every 200 miles"), but some do in terms of time ("I shall stop every two hours"), so these should consider the cube proportion.

Hi Peter,

have you noticed any difference in fuel consumption after changing front sprocket to one tooth bigger one (especially at speeds 130+ km/h)? Any difference in acceleration? Steep hill climbing? High elevation operation (2000m and more above sea level)?

I'll appreciate anyone other's experience as well.
Thanks in advance.

G’day Jurlie and welcome to the forum. Let the search tool be your friend. Others have changed sprockets and there’s plenty of discussion about it.
