Fuelly is a good reference to see what Honda has done with these new affordable world bikes. Obviously the numbers are lower than a hypermiler can get since most people in the USA never touch their bike unless they are going out to burn as much rubber and gas as possible.

Generally true, but a bit overstated.

If what's happening on college campuses is a hint of our future, we'll see a lot more, rather-sophisticated scooters in the next few years. However, it's unlikely we'll see them on I-95. The impressive mpg numbers they rack up is in large part due to the speed regime in which they operate. IIRC, my RD-125 Yamaha got about that same 45 mpg at highway speed as my RD-400, GS1000, and ST2.

What I found impressive about the NC700X is in the comparison to a motorcycle of the same class, it does much better. Take the also 45 mpg SV650S, for example:

My old CG125 clone got 135 uk mpg.... Although it topped out at 34 mph lol

I'm probably gonna flog my xjr come summer and get y dragstar back on the road

I kept thinking about selling it before .... But at 60 it'll do 50mpg.... It'll do about 38 at 90 mph


But more to the point it'll do 0-60 faster then almost anything ..... Such a nice bike

As for my diesel plans.... Soon as I it my house.... With garage ... Might not seem much like a dream to you Americans but I live in London .... I mostly want it cos I enjoy building things.... Sounds like a fun project

If more people were logging the CTX700 it would be even better than the NC being lower and more aero.

nothing on this green earth will get me on a scooter lol... mostly cos you cant grip the bike with your knees... also no scooter is faster then my xjr... its genuinely surprising easy to ride at 4mph and although the bike is wide the handlebars arnt..... its the filtering king..... though a gixer might be quicker..... my bikes like an arm chair..... and although i dont really leave london on it.... i go round the m25... so i need motorway speeds

a cbr 250 i would consider... but to be frank i just dont feel safe on things that slow.... i havent ridden one yet to be fiar

a few times times now some bellends pulled out on me without even looking (there words) and ive avoided hitting anything by blapping my 131bhp 125NM engine and getting the hell out of dodge, its comforting knowing its there

my dragstar with no mods can get 80mpg if your not in a rush on the motorway..... though that drops alot if you go from 55 to 60

plus both of my bikes have road presents ...... people in general seem to see and hear them coming cos there phisically large things.... more then they did on er5..... though i do ride defensive as hell all the time .... but i think the bikes help

Ah yes. Big power to "get out of trouble". I've heard of that.

To be fair, when you "blip the throttle" on anything rear-wheel drive with more than 200 hp / ton, you tend not to hit things head on. More sideways like.

If the dent is on your door, it's not your fault, right?

Also, chuckle at a CBR 250 being "slow"... as it hits 60 faster than 90% of the cars on the road.

also emissions dont even get tested for bikes over here
Keep in mind an engine that seems to be efficient in a car may not translate to higher efficiency in a bike. The reason is all engines are more efficient when loaded, and putting a more powerful engine in a lighter vehicle reduces the load on the engine, so for the same load a smaller engine is generally more efficient.

The great thing about streamlining a bike is that good design offers a great deal of protection with out adding much weight. Smaller bikes with a low Cd can keep up with larger bikes. Any engine with good breathing and a high compression ratio will tend to be more efficient when matched to a chassis that is around 36 lb/hp and a Cd of 0.3 or less. Medium sized frames could handle a small 3 cylinder diesel.
