Trike MPG - What to expect?

[Strohkr]

Hey all!
Just got back from a 3000+ mile trip out to Red Lodge, MT (over Beartooth) and then down to Golden, CO (Pikes Peak and RMNP). Man, what a trip - Pikes Peak sent shivers up my spine - it was so awesome! Flash Flood watch out when we got to RMNP so never did get into the Park - good excuse to go back next year I guess.

Sorry, got off track a bit. I'm riding a 2013 Tri-Glide with what I would call a Stage 1 kit (Fuel Moto Headers, Jackpot Mufflers, S/E hi-flow air cleaner, TW555 cams, and a SERT). It was not dyno'd prior to the trip. On the Interstate at 75-80 mph I was getting 20mpg. When we reduced the speed to 70 or so I could get (maybe) 25mpg but that was about the best I could do. My 2-wheel buds were getting a bit tired of having to stop every hundred miles just for my trike to fill-up :gah:- and I'm not so sure they will welcome me along next time if that continues.

I did talk to a few other Trikers that I met on the road and most were saying the worst they were getting was 30 and most were in the mid 30's and some even close to 40! Most also said that my cams are killing my mileage (and, yes, I know I need to get it dyno'd but most didn't think that would greatly increase my mileage). I was also told that the new trikes (after 2013) have much better performance and much better gas mileage.

So - now I'm thinking of trading up to a 2016 and just leaving the darn thing alone (no mods) or, at the very least few mods (air-cleaner, slips ons and nothing more). Wouldn't mind trading up to get all of the new goodies but if my gas mileage remains really bad it might not make a lot of sense since I'll still piss off my 2-wheel riding buds. And, yes, I realize that my trike is never going to get the mileage of a 2-wheeler!
Kinda in a quandary here - don't really know what direction go :Shrug: any thoughts you have will be greatly appreciated.ThumbUp
Thanks much!

ECM tuner needd

I installed a Power Vision last winter old shiney runs smoother, cooler, stronger, and mileage is running around 32 MPG. I can't stop cranking the right grip I love the curves and hills in PA. For the price of a tuner I certainly would not trade before I put one in. After all you have done you're just a tune away from an awesome running trike. just sayin!!!:Shrug: ride safely fearless

p.s. doesn't matter to me but get it tuned your ECM does not know what is expected of it now.

Stock Feels Good To Me

Running my 2014 just like it was born ... Bone stock with no engine mods. Feels great to me and averaging a little over 35 MPG riding two up nearly all the time. Mostly twisty mountain roads with just a little bit of I-40 thrown in.

 

[cdculbertson]

I am only on my second tank of gas on our week old 2015 Tri Glide that is completely stock. We seem to be averaging around 31-33 mpg. Mostly two up on two lane country roads, with a little bit of I-10. Of course, here in Florida all roads are flat.

 

[Moe55]

We have a 2014 tow a trailer 2 up 90% of the time we get 35-36 mpg most of the time. Highway 70-75 mph it will drop down to around 34. We have got in the high 30's and low 40's a few times. Trike has slip-ons HD Street Cannons and that is it.

 

[Lizard]

So many variables. Everyone posts these high numbers that seem so out of reach, especially pulling a trailer and getting over 30, I couldn't do that with a 2 wheeler. Every bike and now Trike I have had has historically averaged lower MPG's than people around me. Having said that, Running to Sturgis a few years ago, a buddy of mine riding 2 up with a CVO Roadglide and me with 2 up on an Ultra Limited. Every time we filled I added maybe 1/10 a gallon more than him. He claimed 40+ MPG, I never went over 35. Here's some things I discovered.... 1st, your speedo may or may not be off. If it's 5% off (very common to be that and even more), than your MPG's will read 5% high (speedo's are always low, not high). 2nd, Higher altitudes are typically better MPG's, twisties at 40-50 are better MPG's than the same mileage at 70+. 3rd, how you fill the tank is important. The newer FLH's are hard to fill all the way up, and if you fill 1/2 gallon shy one time and full the next, it will artificially change your mileage for those tanks. MPG's must be taken with a large sampling of tanks, 10+ at least, or it's pissing up a rope. Now Trike specific.....70 on highway in 5th will net you better MPG's than in 6th. I no longer use 6th unless I am cruising well above 75. Riding style has a lot to do with it...twist the wick a lot, lower MPG. Lug the engine, lower MPG. Now for my personal Trike....I have a Stage II in mine, a mild cam, Stage I airbox, CVO mufflers with Fullsac 1.5" cores, and a good tune with a Mastertune. I can get very low 30's if I am easy on it, run 5th on the slab. I can get mid-upper 30's in twisties or backroads.

Getting 26mpg

I just bought a Freewheelerand was shocked that I was only getting 26mph on the road doing 75-80 miles an hour. My bikr is completly stock on intake and exhaust. I know that I am not going to get 39 42 mpg like I was getting with my Ultra limited but comon. I met a Triglider pulling a big trailer and he was getting 38 whe pulling that thing All he did was a stage 1 with slipons and air cleaner and tune.

 

[rhino 2]

On my 11 T/G i get 33/34 around town... Highway anywhere from 37/39..
I do have the stage one 6200+ red line, Rush true duals/cat-less, Rush slip-ons [175 with added Thunder torques to the slip-ons] and ride solo. No other work done, like fuel or cams... Sometimes more is less.
Unless done one at a time... So as to know whats is working or not working.. Learned that from drag racing in the early 60's..

Sorry, got off track a bit. I'm riding a 2013 Tri-Glide with what I would call a Stage 1 kit (Fuel Moto Headers, Jackpot Mufflers, S/E hi-flow air cleaner, TW555 cams, and a SERT).

I was also told that the new trikes (after 2013) have much better performance and much better gas mileage.

I had a 2010 Triglide with almost the same combination of parts as you. I switched the transmission sprocket to the 30 tooth. I had TW555 cams, Jackpot head pipe, SE ventilator air cleaner, SE 50 state legal mufflers and tuned with the TTS. Cruising along in 5th gear at 60 mph I'd get anything from 35 - 38 mpg. Running the freeway I would get anything from 33 mph to 25 mpg, all depending on how fast I was going, how many hills and how bad the head wind. A trike is a rolling brick wall, like others said, the faster you go the less the mileage. I see some of these folks posting up numbers I scratch my head over. Its tough to gauge the mileage when you have a tough time consistently filling the tank to the same level, it can cause a fluctuation.

Your tune can be causing you issues, depending who tuned it. Some folks believe in more fuel is better, they make them pig rich and the mileage suffers from it.

Trike MPG

I think FuzzyWazHe is right on with all of the stats that he listed in his reply. I ride a 2011 Tri Glide and have recorded the MPG, weather and riding conditions for the last 2 years with the same results.:GL1800:

As you can see from my signature, I am pretty far from stock - i.e. 120r that I rebuilt to make it more street friendly, and riding with the wife two up, I get between 34 - 37 mpg. However, this is at the speed limit as I ride pretty conservative with her on board. Both of us weigh 295 - 300 lbs total, and when I have checked our weight via roadside truck scales, we are rolling down the road at about 1,500 lbs.

Regarding fill-ups, I stand beside the Trike and "rock-it" with my knee to get every bit of fuel I can at fill-up, this kinda "burps" it and lets you get the max amount in the tank. So I am quite sure I get pretty close to the same level at each fill up. And, I have set my speedo via the PV and my GPS so I know I am right on in that category.

I also think the fact that the larger higher performance engine does not have to work as hard to carry this heavy Trike as the 103's do - my opinion anyway!!!

I also think Fuzzy is spot-on......I have a 2013 with V&H slash exhaust, K&N air cleaner, SE tuner. To be truthful, I didn't buy my Tri-Glide for fuel mileage....bought it to RIDE!! I get around 200-260 miles to a tank of gas....sometimes I run premium and sometimes mid-premium when on a long trip. I don't let the gauge get below 1/4 of tank, sometimes 1/2 if I know there's not going to be a gas station in range.

 

[lah2420]

Here is what I have so far. All stock. Average overall so far is 33.252. Less than I had hoped, but I didn't buy for mileage anyway. I messed up and put 87 octane in at that last tank. I've run mostly non ethanol 91 octane. It's hard to find 93 around here. And don't let that 7+ gallon one throw you. That was a trip I filled twice and just added together.

[lah2420]

I would say most is an average of city and highway. The ones on the same dates were all highway and the one with 7.2 gallons was highway. Most of the others have some amount of city driving. Most of the highway is non interstate two lane. My highway mileage does ok until I hit 70. Then it seems to drop.

I don't know how much better you will do MPG wise on a 2016 over the 2013.

I had a 2011, and now have a 2014. There are a lot of nice things the '14 has that the '11 didn't, but getting better MPG is not one of them.

Fuzzy pretty well covered the variables in his post. I would add 2 more important variables-

1. Heat, if the front cylinder head temp goes over 270* you will see a drop in MPG, so keeping it under that temp is important for optimum MPG. And don't think that the Twin Cool ('14 & up) will run cooler (all else being equal), they don't, or if they do, it is not by much...they will easily go over 270*, just like the 13 & earlier models.

2. Exhaust. Almost every aftermarket slip-on for the TG's are inefficient. Yep, they sound better than stock, but they are not good for MPG. There are things you can do to compensate for that.

On my 2011, on our trip to the Arctic Circle, we averaged almost 34 for the entire ride, and there was a lot of hard riding in that trip.

Since that trip I have learned even more about how to get better MPG, and if I were to do that trip now, I think my average for the 13,000 miles would be closer to 37, or maybe a bit higher. (whether I was on the '11, a '13 or a '14-up)

If you want a 2016, I am sure you will like it. But whatever you have to do to the 2013 to get your MPG into the mid 30's, for your riding style, you are going to need to do the same for the 2016.

btw, the trip you just got back from sounds like a blast! ThumbUp

:Agree: My 06 Ultra with the 120 I built will get 41 mpg when I ride it sane.

 

[KJB]

Wait a minute. Are you saying if I rev my engine at a light I can attract a girl? I'm going to give that a try today. Do you think I would have better luck if I leave my wife at home?

Sorry, on a more serious note stating your mileage on any one or two trips is anecdotal and could make you feel good or bad. My ongoing overall average from day one is 33 something. I'm not home now to look at my spreadsheet but my overall average includes a variety of riding conditions.

 

[screwball]

On our stock '09 and '11 Tri-glides riding from Southern California through Oregon, Idaho, Montana, Wyoming, Colorado, Utah, Nevada, and Arizona we averaged 34 mpg on the '09 and 36 mpg on the 11. Last trip through California, Arizona, and Nevada on the '14 Tri-Glide and '15 Freewheeler we averaged 32 mpg on the Freewheeler and 34 mpg on the Tri. All trikes are mechanically stock, cats in. I changed the mufflers, but not the air cleaners. Usually right about 70 mph in straight roads. Wife weighs about 130# I'm 230#

I doubt if the pipes or air cleaner will affect your mileage that much, the tuner CAN. Good Luck.

 

[Condor]

One of the things that no one has mentioned yet is the gear ratio in the rear end. If everyone was running the same rear end it might be a better comparison.... Also each motor has a sweet spot, and if the bike is running above or below that RPM gas mileage will suffer...

 

[Strohkr]

Now Trike specific.....70 on highway in 5th will net you better MPG's than in 6th. I no longer use 6th unless I am cruising well above 75. Riding style has a lot to do with it...twist the wick a lot, lower MPG. Lug the engine, lower MPG. Now for my personal Trike....I have a Stage II in mine, a mild cam, Stage I airbox, CVO mufflers with Fullsac 1.5" cores, and a good tune with a Mastertune. I can get very low 30's if I am easy on it, run 5th on the slab. I can get mid-upper 30's in twisties or backroads.

Thanks to all for your replies - looks like I need to take it in and get a damn good tune. Guess I'll do that for sure if I decide not to trade it on a 2016 - will probably make that decision in the next month or so.

Yes, the trip was absolutely incredible! If you haven't been to Pikes Peak put it in your bucket list - it's a must ride!! I was awe struck to say the least. Been to the top of Beartooth 14 times - but Pikes Peak was something else.

Lizard - Question: Why 5th gear at 70 and not 6th?

I thought running lower RPM's would give you better mileage? I realize you never want to "lug" the trike but is 70 in 6th lugging it? Hope this isn't a stupid question!:laugh:

Guess my 2-wheel bros are going to have to get use to riding a bit slower and stopping every 100-130 miles or I'll just hafta find different bros!

Thanks again.

I just realized another big variable in MPG is the gas being run.

Not just summer blend vs. winter blend (that makes a big difference), but also the octane, whether it has ethanol, and general quality of the gas can make several MPG difference.

Greg...if you "take it in" to get a good tune, I would take it to someone that, you can verify, has tuned a Tri-Glide that is getting good power and MPG.

It is far easier (and more common) to get a "good tune" that is really not so good, than to actually get a good tune.

The other thing that might be less expensive, and more reliably get you a good tune, is to get a TTS or a Power Vision, and get a good "map" from someone here on the forum.
