What motorcycle or scooter gets the best gas mileage that will go at least 75mph?

I am looking at getting something that gets good gas mileage.... I just don't know what. Any suggestions? Will a Madass go 75mph?|||A 125cc 2 stroke or 250cc 4 stroke will go 75 mph, but it's not really designed to cruise at that speed. The engine is beating its little heart out, plus the suspensions of these bikes are not designed for high-speed cruising so they are not comfortable or safe.





To cruise at 75 mph for any period of time you need at least a 500. A 650 would be better. All bikes like this get about 45-50 mpg. Motorcycles don't get as good mileage as they should because they are not very aerodynamic.





While a 125 or 250 will get much better mileage at 35 mph (maybe 60 or 70) they won't get any better mileage at 75 than a bigger bike.|||Definitely no 75mph on a Madass! It's a fun/cool bike but not very practical and, stock, not very fast.





To do a sustained 75mph, you're going to need something around 250cc or larger. For current, new bikes and scooters, this means a four stroke. Those getting the best gas mileage are going to be single cylinder; fuel-injected engines generally get better MPGs for their displacement. From there, your selection will depend on budget, personal preferences, and how much the gas mileage means to you in exchange for displacement.





For example, a SYM Citicom 300i scooter ($4699 MSRP, but you can probably find a new one much cheaper right now) is well made and reliable and gets 94MPG. A Honda CRF230M ($5399) has been rated at close to that, around 93MPG (in tests; I can't find an EPA rating). The CBR250R ($3999) reportedly gets over 100MPG. If your preference is scooters, the Taiwanese brands (SYM, Kymco, Genuine) offer the best fuel economy and price per displacement. Generally speaking, the cost of scooters/cc is higher than most Japanese motorcycles.





Keep in mind that these all get very good fuel economy now, and when we're talking about anything in this fuel economy range, your cost savings in gas decreases the higher in MPGs you go. So the fuel cost savings between 70MPG and 80MPG are more than between 90MPG and 100MPG. Point being, there's not much use in equivocating over a 5-10MPG difference when it's this high.





Also, these vehicles, have very different types riding and handling. The larger scooters all have automatic CVT transmissions and most have a more relaxed, upright seating position. The motorcycles will be more demanding on a rider but better overall performance.|||Like Smartypants says, some 125cc bikes will "go" 75mph, but not sustain that speed.





If you're wanting something that will cruise down the highway at 75, you have to think not only of the engine but the chassis. Tiny little scooter tires are too small to sustain speeds like that safely. Same with the little chassis and wimpy suspension.





My BMW F650GS single cylinder four stroke is about the smallest bike I've ever owned that is relatively comfortable at 75. Our Suzuki DRZ400 (also a single cylinder four stroke) is horribly buzzy and not at all fun to ride at 75 for more than a few minutes.





I'm not even sure it'll do 75 sustained, but probably the smallest bike that will cruise comfortably at highway speeds would be the Kawasaki Ninja 250 or the Honda 250 Rebel. Our friend has a Rebel and it's top sustained speed is around 65 unless there's a tailwind, or you really want to wind it up.|||Most motorcycles and scooters substitute power for mpg 鈥?a Royal Enfield efi will give you excellent mpg but poor performance, it will reach 75 after a while and is sort of charming in an olde worlde sort of way. But even then poor riding will reduce the mpg 鈥?continual heavy acceleration followed by heavy braking, riding in too low a gear will substantially alter it.





Even the best 2 stroke bikes are guzzlers compared to 4 strokes (because there is little development work going into them).|||i got a 75 honda cl360 goes 110 mph and gets about 60 mpg. and also have a 78 suzuki gs550. it do 140mph...but i aint sure what the gas milegae is..like 40 to 50 mpg maybe|||motorcycle honda nsr 125 2 stroke. 90mph.
