Nobody buys a SS for the fuel economy. When the second bank of injectors kick in on a Litre bike you won't be thinking about the gas you're using 
Fuel economy :Supersport vs entry level bikes going at 100kmph
- Thread starter sid_for_speed
- Start date
Every sportbike I had owned, ridden under mixed conditions on the street, averaged between 40-45 mpg, regardless of whether they were carbed, fuel injected, 600, 750, or 1000cc. Small cars get better mileage, especially if you consider the number of passengers accomodated per litre of fuel consumed.
2 people on a bike are gonna cost alot more to move than 5 people in a Tercel.
Most of the time, the 1000cc 4 cyl ones were the best on fuel, probably because the engine was working so little to fulfill the riding demands compared to smaller bikes.
Average motorcycles have a much greater aerodynamic inefficincy than an average car, so don't expect great mileage.
The only bike I know of that is currently tunes from the factory to car mileage and reliability standards is the new Honda NC700 lineup. The engine is architecturally half of a Honda car motor from the Fit model, and tuned similarly. This is why at 700cc's, its output is a mere 50 hp, and factory claims put mpg around 70, but owners are reporting real world mileage into the mid 80's.

We are talking about mpg in this thread. Efficiency is the name of the thread here.
Obviously, fuel consumption is relative to the work being done.
Example:
2 CBR 600's will use just as much fuel as my 8500 lb van (with 2 bikes in the back) will while towing a trailer loaded with 3 bikes.
So 5 bikers, and their bikes and luggage can get to Deals Gap cheaper in my van and trailer, than two bikers can ride down alone.
Get my drift?
LOL

While riding around Vermont on my 2006 Yamaha FJR 1300, I managed to squeeze 3.6 L/100 km on a 400 km day trip. Riding was done at 90 - 100 km/h. Pretty astounding!
Slightly off topic - My 2013 Nissan Altima 3.5L V6 got 6.5 L/100 km while cruising down the 407 today (average over about 100 km of driving) - also pretty astounding (for a car with 270 HP!)

Most SS bikes are geared to generate good drag strip numbers, but a 2 tooth drop could make a huge difference on the highway for buzz and fuel economy.
Bikes have had advanced designs for power generation, but lack EFI and GDI which would make them better. This will change as emission rules tighten.
The new Honda 500s have remarkable fuel economy.
The truth is most guys who buy those bikes don't care, all they want to see is speed numbers.

I would think that lower gear with same rpm would be better because higher speeds means more drag and the bike wont have an overdrive final gear like cars but you'd also have to compare the power curve for each gear.
In most cases I think you'd probably get better mileage at higher speed/higher gear, but this scenario is too close to call without testing.
The better thing to do is run in sixth at 80. More speed is always less efficient, the optimal speed for efficiency is 80km/hr, which is why the US had the 55 limit on highways during the gas crisis years.
Uhh nope.

If you run the cbr125 at 80km/h in 6th, the bike would probably be slowing down with full throttle..
Assuming that the numbers below are accurate (which I doubt), you'd be running around 3000rpm. Just so you know the bike can get up to around 13000rpm and the powerband is generally around 8000rpm-10000rpm.

Smaller rear sprocket, lower RPMs in top gear. I've used this on bikes that had an annoying buzz at typical highway speeds.

I think he was taking exception to your statement about most ss bikes being geared for good drag strip numbers. I dont agree with that either.
