For those of you who don't know me, I'm all about the environmental and social benefits of motorcycles. This attitude speaks to my general disdain and- let's face it- subtle aggression towards street-clogging cars, overly smug Prius drivers, and bloated "crossover" SUVs.

In addition to being cheaper, faster, sexier, and (I am wholly and utterly convinced) safer than 4-wheeled "cages", motorcycles are genuinely greener than conventional cars, requiring fewer materials to make, ship, and maintain than most (all?) cars- even green ones! In addition, they're almost always a more fuel-efficient way to shuttle environmentally conscious commuters who aren't afraid to get a little wet every now and again to and from work, school, and- with the right luggage and smart shopping- even the grocery store.

For 2015, we've been cursed with goodness on all sides when it comes to fuel-efficient motorcycles. There are slick scooters, outrageous cruisers, and even a few surprise appearances by companies that, frankly, we didn't think would still be around the last time we put together a "best bikes" list. That said, this list of is sort of informally divided up into categories, so there's no "winner" here- they're all winners! Shall we get started, then? Here is Gas 2's semi-official list of the 11 best fuel-efficient motorcycles you'll be able to buy in 2015. Enjoy!

2015 Honda Grom 125 | 103.5 MPG

City Bike

Remember that part where I said there was no winner? The Honda Grom 125 comes real close to making me ignore that nonsense- and why shouldn't it? Honda's best-selling, 50 MPH new-age monkey bike is utter bats*** insanity wrapped around a solid, reliable 125cc Honda dirt bike engine that won't leave you stranded. It's lightweight, small enough to sneak onto the bike lane without attracting too much negative attention, and good for 103.5 MPG in real-world conditions, according to MPG crowd-sourcing site, Fuelly.

2015 Motoped Pro | 100 "ish" MPG

Moped

If there's a better bike to blast across the bumper-to-bumper, rush-hour grind of major cities than a Honda Grom, it might be the Motoped Pro. Built and spec'ed by you, the Motoped client, you can go for the BMX-inspired "pro" shown, above, or the more outdoorsy "survival" model meant to whisk you away from the city and deep into the forest primeval, where you'll be forced to face down hordes of flesh-eating zombies or, you know, glampers. Either way, you can't go wrong with the ultra-lightweight, full-size banzai experience the 100-ish MPG Motoped offers … and it, too, is powered by Honda.

2015 Yamaha SR400 | 66 MPG

Standard

Few bikes on the market today capture the idea of the Universal Japanese Motorcycle (UJM) better than the Yamaha SR400. Launched earlier this year, the SR400 evokes classic Yamahas of the 1970s and early 80s in terms of look and feel, but modern brakes, suspension bits, and tires mean the new version is worlds ahead of the 1975-81 SR.

2015 Yamaha Star Bolt | 51.6 MPG

Cruiser

When considering a middleweight cruiser for this "best fuel-efficient motorcycles" list, Chris and I almost chose the new-for-2015 Indian Scout for this list. In the end, however, it wasn't the Indian or even the newest Harley-Davidson Street model that best captured what I think of as "a modern American motorcycle". It was this, the 51.6 MPG Yamaha Star Bolt.

The Yamaha's 942cc air-cooled V-Twin sounds like 'Murica, and the fit, finish, and look of the Bolt is absolutely pitch-perfect as a bobber. And, if Harley had smart product-planners working for them in Milwaukee, they'd shelve the shoddy-looking, wires-everywhere, Made in India "Street" lineup and license Bolts from Yamaha. The fact that the Bolt is about $2000 less than a comparable Harley, too, would mean Harley dealers would have plenty of "H-D mark-up" room.

2015 Honda GoldWing Valkyrie | 35 MPG

Touring / Big Cruiser

The 35 MPG fuel economy rating on the 2015 Honda Valkyrie may not seem impressive at first glance, but I can't think of anything faster that gets better mileage. When Honda announced the GoldWing-based Valkyrie last year, it was unlike anything else on the road. It's still unlike anything else on the road- and it's still got a better power-to-weight ratio than Nissan
