That Didn't Go As Planned: Can The Honda Navi Beat The Monkey In This Surprising MPG Test?

[@jeanP924]

I am so excited I just bought a red Navi and a green Navi. I can't wait to show all my friends how they can spend quality time with the grandkids! We are the cool grandparents in town!

[@a.foster199]

I don’t think this is very fair situation to test the Navi. It’s not really for someone in Colorado pinning it back trying to beat headwinds on a cross country highway. Let me reassure anyone who has one ordered or wants one. I got mine in the last couple of weeks and have been riding it every day I can. For context I live in hilly Seattle, and I’m 212 lbs. My first tank of gas got me around 60 miles. But each subsequent tank has gotten me more and more. I think I’m up to about 75-80 mpg depending on my route. We have a lot of 35-40 mph two lane highways that are inter-suburban traveling roads. Most people go about 40-45 mph on them, and the Navi stays right with them. The steeper hills keep me topped at about 35, but I just navigate myself to roads that are lightly used so I’m not really bogging anyone down. More often than not, on my routes, someone is holding me up more often than I’m holding up someone else. The important part is just finding routes to your destination that are a good fit for a mini moto. I’ve had an absolute blast on mine, and I just wouldn’t have been able to afford any of the pricier bikes, especially the way they mark these up in the Seattle area.

[@urmomwuzhere]

It's a city bike that can get on the highway briefly in a pinch. This wasn't really an ideal testing ground.

[@reedstemen]

PREACH! I just did 500 mile trip in southern Indiana/Kentucky and this is exactly what I experienced. Navi is perfectly adequate for non-highway less than 55 riding, 60 miles to completely empty, I got 70ish mpg the whole trip. Wish the tank was bigger but me a friend on his navi carry extra fuel just incase.

[@ZantharEos]

I don't think the monkey is a better value at over 2x the cost. And yeah shifting is fun. But you know what's more fun? Buying 2 navis and riding with a friend

[@Handsygrandma]

It just feels like we took a Navi and didn’t break it in. Then we took it on the freeway and pinned the throttle the whole time. So on one hand, we’re putting the bike through a realistic situation it will be put in from time to time. But on the other, it was kind of out of its element into a headwind and without a good broken in engine that uses a carb. So your numbers are real. But not a true representation of the bikes average performance over time. I’ve been going 60 miles on .55 gal consistently. Just to put in my two cents. Following the break in process so far. This video depicts a rare situation and I’m sure I would get 80mpg doing that. But the way I’ve been riding mine around town, it’s been 110mpg. A little less for the first 100 miles. Just about 300 miles on the odometer now. It’s a delightful bike for the environment I have to ride in.

[@ghillysniper45]

Tbh I also don't understand the reason they pinned the throttle, like I understand most roads in the US are above 30mph but the economy band on the Navi is 30-40mph so them having pinned the throttle is a bit defeating of the purpose of the test imo

[@TheAnnoyingBoss]

@@ghillysniper45 bro you have to pin the throttles on all the mini motos. They live their whole lives right at redline. BakerxDerek In Cali has been riding groms for years pinned at redline.

[@andrewgee241]

If they didn't pin the throttle they would have been run over by a 5000 pound vehicle.

[@dylanneal6363]

change the clutch out, there's a KZbin video of a guy changing out the clutch on his and after the clutch swap. his clutch weighed 2.5lbs less. which really helped acceleration and probably mpgs too. I was really impressed.

[@Peter-mcmcmc]

As the owner of a '21 Blue Monkey, I like the videos you've made on this bike. Good stuff; thank you!

[@Prepare2Survive]

That means the Monkey gets 72% better MPG than the Navi. My Honda Ruckus can do 43mph on flat roads and I've been averaging 105mpg with it. I'm guessing you might need to adjust your carburetor for the higher altitude.

[@siddharthkapadia7674]

I had a scooter with same 110cc engine that gave me same mileage around 35kmpl that is around 80mpg. Mine was Honda Activa 2nd Generation. Honda later solved this problem later in 4th Generation models which gave around 50kmpl.

[@TheAnnoyingBoss]

@@siddharthkapadia7674 pretty weird to me that the 110 smaller navi gets worse mpg than the 125 grom. Maybe it has something to do with efficiency. I had a 2008 Kawasaki Vulcan 1600 and it would get about 35-40mpg how I rode it. My father has the exact same year motorcycle except it was a 2000cc and I would get 45-50 on that driving the same way. Bigger engine but better fuel economy. I think this happens because my 1600 had to work ever so slightly harder to propel me down the road. The 2000 burns more fuel per ignition in the cylinder, but it is a stronger engine and so it would get you up to speed a little faster than the 1600 and it would sit lower in the rpms to propel me at faster speeds. So my speed would go up and my engine rpm on a larger engine would go down, and I'd end up getting better fuel economy on a bike with 400 more ccs worth of displacement. I think it has to do with something like that. The 2000 was heavier than the 1600 too. It got better fuel economy with saddle bags and bigger windshields and accessories too. I think it just has more power and so you get up to speed faster and end up using less fuel eventhough it's a bigger engine with more power. Idk. I could be wrong.

[@TheAnnoyingBoss]

@@MrMoneyHelper interesting that you mention this. I didn't know BMW performed this experiment. Very interesting 🤔 could be that too. Better gear ratios for the speeds in my area could also play a big part

[@jarekmace1536]

I'm seeing comments about break-in and re-jetting, but you also didn't couldn't take into account the fuel wasted playing in the dirt that the Monkey didn't do. That burns A LOT of fuel. Remember, acceleration is where the most fuel is used.

[@gwlane5509]

And the fact that Navi rider was full throttle all the freaking time...on purpose I'd bet....

[@speakingout6345]

I know the Navi is basically a scooter but the price is really impressive. If only they offered the Honda trail for near this price and offered cheaper shipping.

[@andrewsmith9575]

Another great video guys! Re-jetting the Navi would help, but you will shave top end speed off doing that. Because of the thin air we deal with here, sea level tuned bikes loose at least 15% in performance and fuel economy (carbureted). Fuel injection tames that a little, but still will loose performance. Because you two have not lived here long, I would love to show you how to get from the studio in Boulder to the tumble weed ranch on all back roads with posted 45 mph most of the way. It would add maybe ten more miles and 20 min longer, but your reduced heart rate and increased safety make for a really fun ride. Bikes were designed for urban city riding. Ringing the neck of these two mini motos on hwy, the Navi will become a big gulp on the fuel side, with the Monkey not so much.

[@jareddegood8313]

Awesome stuff guys. Would like to see the Navi’s carb set up professionally by a mechanic with optimal air/fuel ratio and run the test a second time. Or maybe see how the Navi compares to a Honda Ruckus for a little more money.

[@vincentvaicunas1458]

Considering your elevation and the difference in price your the Navi did well. At half the price OTD it gets more than half the mpg. Once your Navi gets some miles and warm weather it should do better in the MPG department.

[@anthonyrstrawbridge]

Interesting comments. The valuation comparison makes sense. I was thinking about the break in period too, maybe 500 miles until the engine fully breaks in? Warm temperatures result in less air density though. Generally speaking, a 4 stroke combustion engine loses three percent of its rated power for every 1,000 feet of altitude gained.

[@thatguyjd281]

[@Osprey81]

I would think a carb rejet would be a good idea for the carburetor in the Navi. That thing has to be running super rich at that altitude.

[@ark6959]

I thought that as well. I have a Navi and it came stock with an 85 main jet. Since I live at 6700’ I ordered an 80 main jet for it. Turns out the 80 was a bit lean (in cool weather). I put the 85 back in! Mileage doesn’t really matter to me since my commute is only three miles and the Navi is just so fun for my needs. Also, as it is breaking in, the power is improving and the suspension is too. Still won’t compare with the fuel injected and better suspended Monkey. Apples to oranges, haha!

Yep, I was surprised when my Navi ran down to reserve at only 53 miles the first time. Re-priming the carburetor at 11:35 can be very tricky in busy traffic. Preventing engine flame-out while switching to reserve is tricky, and rolling restarts aren't always possible. 😉👍 --QM

[@56chevyguy]

A rolling restart I dont think is a possibility on the Navi considering you have to have the bake applied to use the starter

[@QuasiMotard]

@Squid Missile It can be done, but the timing is tricky. The brake only needs to be applied enough to engage the brake switch and enable the starter. The problem is that the Navi slows down fast without power, so you could end up sitting still before it fires up again... ask me how I know! 🤣👍 --QM

[@johnbeaudette583]

In MN at 1,100 ish foot elevation. I only weight around 80 ish lbs which helps. My 21' stock monkey started at around 70 mpg and increased everytime I checked it. I have gotten over 170mpg for 4 tests now at normal riding with some fun here and there. 170+ mpg is with a Apache 2800 case on each side of the back rack and a Apache 4800 case on top of the rack. About 5 lbs in each side case. Top case is still empty. The Top case reduced my top speed from 68 to 63 MPH. (Hard to tell it's always windy here) 2 milage tests without and 2 with the top case. I plan on cruising it around the country , hopefully the mileage remains high when I add a trailer behind it. Thanks for the video. Cheers

[@luvnotvideos]

Smaller tires and slower speeds makes for a rougher time on the road. For pure city commuting, or a first bike someone rides to school, the Navi would probably be just fine as long as secondary neighborhood roads are taken. But I wouldn't recommend it for longer commutes, aggressive traffic, or on roads with a lot of potholes.

[@suomenpresidentti]

$ 4.79 per gallon? Crazy cheap. It's $ 10 here In Finland. I can get 190 Mpg with my 2019 monkey when driving gently. Done 20k miles with the thing and loved every one of them.

Two questions. How many miles on the Navi? (broken in?)what is your elevation? It says in the manual to re-jet above 5000 ft. Great video. 🐵🛵🙂

[@J.Young808]

TFL is always talking about how they are a mile above sea level (5,280 ft) in their Car/Truck/SUV reviews. Boulder where their office is sits at 5,318 feet. They said at the start they haven’t re-jetted the carb yet. Not sure why they didn’t remark about that in the ending.

[@bigretardhalo]

Came here looking for a comment about the Navi being carbed and potentially running fat for the elevation… I think it had a lot to do with it… that being said chalk up one more reason to like fuel injection.

[@kf4293]

This was very enlightening. I've been interested in the Navi, but I'm thinking something with the 125 would be better now.

[@xorbe2]

My 2022 Grom dash claimed 165 mpg before I sold it. I said the Navi was going to be an mpg lemon (carb + cvt + less power) but nobody wanted to hear it. Both are too slow though, we need a 200cc Grom, that would sell way way better than the current Grom, it would be 50-state freeway legal and top out at an honest 70 which is usable.

I have that exact monkey, same color. Very dependable and I get a lot of comments when I stop at gas stations to get a coke. The seat is very comfortable. I like to ride mine much slower, maybe 40mph so I stick to the backroads. I bought it to take camping and maybe cruise the strip down at Panama City or Fernandina. Haven't had the chance to do that yet.

[@fly1327]

My experience on my previous 1966 S90. Running around conservatively, really great mileage similar to the Monkey here, but when you're WOT all the time, well WOT is not efficient at all. Tells you there's a sweet spot for non-freeway commuter bikes, me thinking 125-150cc.

[@Kamarov2090]

Given that the navi is basically honda activa with a different body you should get about 45km/l i think the fuel economy took a big hit on the highway section since it really not "geared" for american highway speeds

[@oiulti6900]

Bought the Navi for when I need to ride to the train station, and picking up dinner (or anything around town) when needed. Exactly what it was made for, and does the job stupendously. Glad they made the Navi with it’s storage space (chef’s kiss). Honestly, if you’re not riding on the expressway for more than 30+ miles, there’s no point to buy manual motorcycles anymore. Navi is the best Minimoto for any city riding, it’s no fun to shift gears in a city. Navi like bikes such as EV motorcycles will probably be the hottest thing in the future for vehicles on two wheels.

[@farragonepenthean4713]

I’d like to see this test conducted again once the Navi has had plenty of break-in miles. I’ve noticed that these MiniMotos dont get nearly the mileage they should until they’ve got 400-600 miles on them.

[@TheAnnoyingBoss]

@@travisb9130 I think Honda needs to cram the rebel 300 engine in the Grom, trail 125 and the monkey. Sell it sorta like how they do the rebel 300 and 500 except sell the minis with the 125 and instead of calling the rebel that has 276cc or whatever a "300" like they do now, just call it a 250 so they can say you can get a Grom in a 125 or 250. Plus the rebel 300 engine has a 6 speed. So you could get the 125 in 5 speed or a "250" rebel 300 engine with the 6 speed. Then you could actually take the Grom probably even up above 80mph pretty easy since it's so much lighter than the rebel 300. Maybe even add cruise control as an option to the 300 Grom, a bit like how the rebel 1100 has it from the factory. Then you could actually build a legit touring Grom that can go 80 mph from factory even if you throw on a windshield and saddle bags. Would be so cool. Keep it on scooter tires. I think if they did this with all the minis, if they made the larger engine options belt drive instead of chain, that would cut down on maintenance too. I've never had a bike where I have to clean a chain. I hate cleaning chains

Would definitely be interesting to see if the grom gets better fuel economy at speeds below 40. If your cruising around a small town at 30-35 all day just putting around for fun, it would be interesting to see if the Grom starts to fall behind in mpg or not. The navi probably gets better fuel economy the slower you go. Slower you go the less you'll burn so it probably matters less at that point anyway though tbh. Plus how do you get a miles per gallon if it takes you longer to go a mile? Will it burn more or less? Idk tbh

[@WW-wf8tu]

I am not surprised by any of this. They are not designed to do what you just did. While it was not planned to happen that way, it just goes to show, play things like those bikes should stay inside of the school yards. lol I would not buy either bike for anything more than putting around camp grounds or small towns.

It really surprised me how far the Monkey could go on a single tank of fuel being pushed hard. Gas stations in TN/NC mountains were not everywhere and the only time I came very close to running out was Cherohala Skyway (A whole lot of clutch coasting downhill was involved) 😅Now my CRF450RL Hell Nah 80 miles and no fuel gauge, talk about sketch. So if you plan on some long distance hauls on a Monkey it's got enough fuel to go further than you think it would. Just plan out your gas stations ahead of time.

Navi is running rich due to elevation is my guess

[@badass1g]

This!! They need to try 85 or 87 octane and it will run better at this elevation. Running to Rich with 91

[@TheAnnoyingBoss]

@@badass1g I might be dumb, but why would octane have anything to do with if it's running rich? If it's running rich it's going to run rich whether or not you use premium or not, simply because it's got too little oxygen at altitude and thus it has too much fuel to get a full burn without having extra going out the tailpipe wasted. Only issue is, since it's carbed you could just re-jet it, but while that's a solution, if you ever find yourself riding your navi at sea level, then you'll be running too lean, with too much atmosphere and not enough fuel. For a bike like this getting the mpg it does, if it was me I wouldn't even sorry about the hassle of rejeting the carb. 80 mpg not fully broken in is still very good for a 2k bike from the factory. Probably not worth the effort in rejeting unless you're quick with it. The money it would save you might not counterbalance the time it took to re-jet the carb for Denvers high elevation 😂

[@DuggleBogey]

You can't get out the door with a Monkey for less than $5K. Three thousand dollars buys a lot of gas even at 79Mpg. The only reason to buy the Monkey is that it is more fun, not to save money on gas.

[@PhilipStratton]

Agreed, $3k gets you 600 gallons at $5/gallon. Getting 80mpg would mean your break-even point is nearly 47k miles. The Navi is a better value from a strictly financial perspective. Maybe not the better choice depending one’s use case.

[@robertherlick8554]

Was under warranty, so Honda fixed it for free. I used the visit to the dealer to upgrade to a bigger bike.

[@thepab3072]

I think the best one to get is still the Grom, cost less than the Monkey, comes with a better gauge cluster, same everything as the Monkey. The Navi is perfect for what it is, it's a great scooter/bike. I'm sure the carb isn't adjusted to the elevation and it's why it did so terrible in this MPG test. It's not an highway bike, ride slow and relax. I'm actually going to buy one , need a small commuter bike.

I asked the dealer why such a disparity in my fuel economy, versus what was claimed by Honda, and he said that the way Honda gets those fuel economy numbers is they run the bikes at 45 mph on a large oval track, with a light rider.

where I am (Canada) the Navi is $2300~ and the Grom(same engine, same everything but looks are diff) is $3900~ so you could afford the Navi and basing the cost of gas per gallon in Canada as $7.692... roughly 208 gallons of gas before you catch the Grom in price... so you could go roughly 16,000 miles (based on 79 miles to the gallon) before you get to pump 1 gallon into the Grom. Prices vary depending where you are... I could do the same calculation for the US but you know how much it costs near you... blah blah blah... anyway, don't actually care which someone picks because both look like fun little bikes.

Dang it! I was going to post my prediction before watching the video, but the last commenter already told me everything! I predicted the bigger-engined Monkey would win, based on #1 being fuel injected, #2 having to use less throttle so poor soul on Navi can keep up, and #3 potentially gearing. CVTs are not as efficient as they're cracked up to be. Among Honda's minis, I prefer the most modern Grom because of slightly less weight and better aero (big deal with less than 10 li'l ponies), more modern Gauge cluster, lowest price among all the 125cc's. As a result of being less 'nostalgic', it gets better mpg and higher top speed as the others with the same engine. Better mpg than the slower Navi with smaller engine! Now I'll enjoy the video!

Yall should go to denver and set up a loop and drive till the tank is dry.

Probably more like a little city block hopper for some one who lives in a Denver highrise with limited space for parking and a minimal commute to work or chores. Also probably the highest speed limit these people would be seeing would be 35 or 40 mph. Just an observation. Sweet video though, I miss Colorado big time.

Honestly you’d be better off with Honda Metro or a Ruckus instead of a Navi.

[@badass1g]

At your high elevation you could and should def experiment with running 85 or 89 octane because you’re running to rich on the navi at high altitude. It would run better with lower octane in that situation.

[@alexp6409]

Did you fill both with premium at the beginning like you did at the end? That could have had an adverse effect on both power and MPG since both are designed to run on regular (87 in the US)...

[@frostedjedi]

That's not how octane works. That wouldn't affect the outcome.

[@alexp6409]

@@frostedjedi Either way, it's a waste of money to put premium in a vehicle designed to run on regular.

[@frostedjedi]

@@alexp6409 very true. Although at .5 gallons, a negligible cost.

[@johnw65]

@@frostedjedi A carb bike not rejetted for high alt. will run better on lower octane fuel. 85 octane would be way better for the Navi than 91...

My first tank of fuel on the Navi, I got 101 MPG at sea level. I was going up steep hills half the time (full throttle) and then back down them for the rest of the time (no throttle). The second tank, I drove on mostly flat terrain, most of the time spent driving full throttle at 40-52 MPH, and got 75 MPG at sea level. I definitely don’t think their claimed 110 MPG has anything to do with highway speeds, but rather driving at 25-35 MPH. I’ll find out soon enough. I appreciate your comparison to the 125cc engine. I think for people who have the money, you’ve proven how beneficial of an upgrade those extra 15cc’s are-and then you’ve got disc brakes, better wheels, fuel injection, and real gears.

[@lisamcdonald1697]

Did you get rid of the govern bolt on the carb?

[@izaacmp]

@@lisamcdonald1697 No, what does that do?

[@johnw65]

Carb vs Fuel Injection.... Not surprising. Also, How did rider weights and apparel compare? I noticed the Navi rider wearing a baggy coat which itself is not good for fuel economy.

[@johnw65]

This guy needs more experience. Carbed scooters do best between 1/2 and 3/4 throttle. Full crank wastes a lot of fuel.

[@supersteve8305]

This is a great example of carburetor versus fuel injection. Honda needs to upgrade the Navi to fuel injection IMO.

[@venza907]

Navi is more of a city bike, not for hwy.

[@Surestick88]

Belt style CVTs have their advantages but efficiency isn't one of them. On something underpowered like one of these the difference in efficiency vs. a traditional transmission is going to be a huge factor in fuel efficiency and top speed.

[@milo8425]

"we didn't tune it for altitude even though it's not fuel injected." Also "Let's test its performance!"

[@jonnyboy1561]

You'd probably get better mpg if you didn't run "premium" its not higher quality, just higher octane. No added benefit and sometimes it causes poorer fuel economy.

[@AhmadAlAjeel]

Is that the 5speed monkey or 4speed? I have the 2019 4 speed, is there any major differences in mpg? Im sure 5 speed will be better on gas mileage but by how much?

[@garybrown9062]

Monkey is nice but the Grom has better instrumentation now and is a better value than the Monkey. That being said the Monkey and Grom get even better fuel mileage with the new more efficient motor and 5 speed transmission.

[@ppipowerclass]

The navi would be best for people just starting, due to no clutch and the much lower price point.

[@JesseVad]

$4.79 per gallon? I'm paying $6 😳 That was a nerve wracking ride but thanks for doing this test!

[@ivanlucian2005]

In eastern Europe we pay almost 9$/gallon. That's some cheap gas

[@cerealtiller]

Was the Navi's Choke partially Closed?

[@isrealhopkins]

Did y’all hit the Reserve tank on the Navi ?

[@tommays56]

The EFI motor is ALWAYS going to be better Having ridden my carburetor Suzuki GS850 through the West several times it always barely ran at high elevations

[@MrCatalina31768]

I love my monkey. I wish I had more time to ride it!

[@richardwilliams6982]

Is there a way you can upgrade the tank on it to a bigger tank I like to upgrade mine to 1 2 gallon tank or 1.5 gallons is it possible to see a video on that

[@arcris1]

You do get what you pay for. The Navi Was designed for Intown commuting not Highway riding. Fuel injection versus carburetor? What would you expect?

[@jaredschultz7358]

Fuel injected engines automatically just for elevation to the O2 sensor carbureted engines do not

[@timothymidkiff2894]

That's odd my 05 honda rebel 250 that I commute on gets equal gas mileage as the navi. But I stick to 35 to 50mph backroads for work. I don't get that on 60 to 70mph interstate traveling mine mpg's will drop 69 to 74 mpg's real quick.

[@joecamel6835]

There's no way unless the Monkey wasn't broken in yet.

[@johncollins5552]

Are there standard road tires on both bikes or is there an off road/dirt hybrid tire. The sizes are different too, the navis smaller diameter wheel has to turn a lot more revs per mile perhaps?

[@GrotrianSeiler]

Have you guys done a Monkey vs Grom comparison?

[@spacemonkey4916]

This video made me make up my mind in regards of purchasing or not purchasing the navi. Don't get me wrong, I'm sure it'll be great in the city or around town. But driving long distance, whether it's 50 to 100 miles just doesn't seem promising. Especially in higher speed zones. I've been wanting to purchase the honda monkey for a while, just wish I did before they raised the price. So I'll be purchasing the honda monkey in the near future.

[@moctarjohnson8887]

Exactly the reason I don't buy carburetors on bikes anymore, I'd rather just replace the pump on an injected bike than pay more money for fuel on an incorrectly tuned carb. Some people like it, I say its obscelete technology

[@MrCODEmaster00]

What about Honda Grom vs. Monkey? I like look of Grom, and practical design, more than Monkey, but like the Monkey's MPG.

[@tackcoma5280]

Did you guy run that back up fuel tank on the Navi? It should give you another 10 to 20 mile

[@Clearanceman2]

Those bikes, especially the scooter are for urban commuting.

[@petethegrip4556]

I have the trail 125- automatic, 4 speed- Not sure why Honda didn’t give it the 5 speed? Screaming on a flat highway hitting 55-60 would love to shift to 5th gear :( The groms go right by me with that 5th gear

[@spymaine89]

IF YOU ARE afraid the semi has an insane driver and will crush ,you, pull off road and wait for it to pass. you may be insane

[@royromero8496]

You can ride the shoulder lane it is considered the slow vehicle lane it is done all the time for farm 🚜 equipment

[@richardwilliams6982]

And it’s possible to upgrade the engine to a 150 cc would like to see that too like I said I have one and so far just makes it seem it’s not a good travel bike for long distance it’s good for around town on 300+ might get even shitty mileage for distance at top speed but mine does seem to get up to 50 but that’s like peg to the floorboard

[@suomenpresidentti]

Why do you not evade to the shoulder for the semi?

[@todd2000gcinet]

Would you be able to take it back to the dealer and tell them the mpg and have them go over the Navy and see if something might be technically wrong? I still think the Navi would be a good bike for some people.

[@bigretardhalo]

Could be running fat.. carburetor at altitude if it’s jetted for sea level it isn’t running optimal, of course that’s one more thing to like about fuel injection.

[@Clearanceman2]

I feel like it's a tough day when a monkey has more power than what you are riding.

[@jeladsnikpoh1289]

My Ninja 300 has gotten better mpg than that Navi! There was an MPG test with a Corvette and Prius @ 80 MPH. The Corvette got better fuel economy. I've owned several vehicles where the more powerful one got better mpg than the little weezing ones. Has to do with not revving the snot out of them. I had 2 big ol' Pontiac Bonnevilles with 3.8l V6s that would get better highway mpg than my gutless 2007 Hyundai Accent (1.6l). My LS1 5.7 Corvette can also easily match it on the highway MPG! Sorry to say, but the Navi has no use in America, except city commuting. I live in rural country and have no choice but highways, so I would need a souped-up Grom at minimum! And it certainly wouldn't be an 'only' bike.

[@KungFuChess]

Navi is meant for city commuting. For that it's the best.

[@reneantunez1998]

In cali the Navi would be perfect.
