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

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

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

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.

@@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.

@@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

@@TheAnnoyingBoss automatic transmision consume more gasoline...not only that the engine is smaller wich means that an adult riding the navi will make the scooter demand more.power.

I've got a Yamaha XF50 C3, 49cc, does 45+, and gets 135 mpg, it's insane, lol.

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

@@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.

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

change the clutch out, there's a RU-vid 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.

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

@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

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.

My Navi got crap mpg the first 400miles like 50 miles a tank(regular tank with out reserve) now it's about 70-85 depending on riding

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

how is it? i weight 190lbs and want to get a navi

@@coralcortez3879 so far I like it more than I thought I would. I have bigger bikes , but the Navi is relaxing to drive around on, just twist & go . Got it for my daughter, but I ride it more than her .

@@coralcortez3879 Like Pete Scaperi, I bought my wife a Kymco S200 (163cc) scooter, I've put 1500 miles on it and she hasn't even rode it yet! My son bought his wife a Navi and same... He rides it all over the place! LOL They get best mpg backed off full throttle. So, this test was misleading.

@@coralcortez3879 I have a 2022 Navi and I am 240 lbs. It will go 45 easily with me on board on level roads. Up hill usually will slow down to 40. Gas mileage is about 55 mpg before reserve switch goes on.

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.

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.

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!

I'd like to see the Navi style conversion on a People 175 or Honda equivalent.

Crazy isn't it! After a mere 38,000 miles you'd have paid the same for the driving the Navi as the the Grom lol

I think 250 is the sweet spot for small motorcycles. With anything smaller you are giving up something.

I have one and it's still lacking on the highway. It will do it but will buzz your hands off. Absolute top speed on mine is 78.

@@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

Gas was $1.20 for around a month in Toledo, OH 2 years ago in 2020 lol

No need to break any brand new engine in tbh.... but yeah go like 700-800 miles and you'll know what's you're getting into

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

@@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 😂

i was considering a bike for local area and youtube has really been getting me with all these bike channels being from around here!

Let me hold 500k 👀

Gimme 1k pls 🥺

Hi, uh, I’m a distant cousin of yours. My name is Greg. Uh, let me know how I can provide value

@@athiftsabit1208 😢😂😂😂😂

It's a good comparison. I was expecting the Navi to have better gas mileage than the monkey because of its smaller engine, but this test was a good indicator that it's not what Honda claimed it to be.

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

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

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

@@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...

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.

Grom

@@MrMoneyHelper thanks man. That's interesting. Sounds like that size motorcycle is the sweet spot for mpg.

$2500 OTD with title and registration fees included. Indianapolis IN. 200 miles in and tons of fun for city riding.

@@_purge9488 I ended up buying a Honda Ct70 clone that’s 125cc delivered for $1600. that looks and works great.

@@imperialrving4435 not my style but looks fun!

1800 where I'm at in texas. They got a crap ton of them 30 miles from where I'm at, at that price.

That's because their are a bunch of low life dealers out there that are just raping the public. Thousand dollar mark up, SMH. I found a dealer here in California that's kinda far from me but no mark up, no prep fees. I have to wait till the next shipment to get mine but I'm saving 1600 bucks. I'll wait.

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

@@MrMoneyHelper Thanks.

@@MrMoneyHelper cool. Thanks.

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