Title: Mpg?
Post by: McCrae72 on April 16, 2018, 03:07:02 PM
Interested in what mpg others are getting from their gen2’s.
I’ve just completed an 837 mile trip to the lakes and my mpg average went up to 49 but is now back to 48.8.
That doesn’t seem overly good to me?

That seems pretty good MPG. My Gen 1 only gets just over 40mpg

Don't forget that the UK gallon is larger than the US gallon.

Good point ijinak:

40 miles/ US gallon = 48 miles / UK gallon.

Yeah I just found that out too, ok maybe I’m off with my expectations, just thought that I’d get more mpg especially on motorway cruising.

I know that my gen1 gets down into the mid 30's when riding in town.

The mpg control is in your right hand   :008:
I have seen over 50mpg average.....but don't dare check it if I'm pressing on a bit  :164:

Post by: McCrae72 on April 16, 2018, 07:58:21 PM
So I’m getting pretty good mpg and I need to ride my bike harder is the general consensus  :152:

Doesn't sound great. I usually get 51-54mpg Imperial on my Mk 1, including motorway work. On Sunday I did about 230 miles with top box and panniers cruising at 80 indicated and got 54mpg. I've got that down to about 48mpg when cruising at 90 (indicated). I have a Madstad screen and winglets, and I think those cost me about 3mpg relative to the original screen, but that was too noisy to use at speed.

What speed are you cruising at, and do you have luggage? What screen are you running?

Post by: McCrae72 on April 16, 2018, 09:24:17 PM
I have the ali panniers and top box, not fully loaded as I was only away for a weekend, motorway work was conservative so 80 to 85 but mostly 80. Standard screen and winglets, scorpion exhaust. While on the motorway homeward the mpg dropped from 49 to 48.7, I do have the occasional burst of speed but mostly cruising. To be fair I was expecting to see 50+ mpg but I really don’t know how I could achieve that without changing my riding dramatically it seems.

Have you done the 12-minute tune up since installing the Scorpion exhaust? My mileage actually improved by 0.6 ltr / 100 kms after I installed the Arrow exhaust and performed the 12-minute tune up.

Riding one-up I usually get around 52-53 mpg, I don't think I've ever got it down to 50 no matter how I ride. The average stays pretty much constant riding local with a topbox or touring europe with heavy panniers and the topbox. I have fun but don't scream the engine everywhere.

No I haven’t, but the fueling doesn’t seem off. Maybe I’ll give it a shot and see if it helps.
The bike has only done 2k miles so probably will loosen up a bit more as yet.

It's an easy fix. I highly recommend it.  :002:

On my Gen 3 with spirited riding commuting from Essex into London every day, I get about 43mpg. On longer trips on the Motorway, I get anywhere between 50-60mpg depending on traffic and speed. If I was to stay in the slow lane I reckon I could get 80mpg easy.

Lets be right here, if you're worried about 2-3 mile per gallon, it's maybe time to give up biking.

My gen 3 I get about 45mpg (US) commuting and I think 55mph for a long trip I could get into the 60s for mileage.  If I hit the interstate and do 80 mph (the speed limit here) I am down around 30-35 mpg.  I have a top box but no side cases.

Well, it is not just the cost, that is a concern for some, it is also the range, given the smallish fuel capacity of the TEX. Not everyone rides in places where there is a gas station every 10 blocks.  :038:

Well said.
It’s not about costs and I’m not likely to stop riding after 30+ years because of the mpg, I was interested to see how my bike faired compared to others as a sub 200 mile tank range is new to me and I wanted to make sure it was normal.
Title: Re: Mpg?
Post by: unsubtle on April 17, 2018, 07:24:58 PM
The fuel gauge is not as good as it might be. I run down to zero miles remaining at about 190-205 miles from full. I've run it 20 miles at 60mph past that point, but I think most people would be nervous about burning that last reserve. Pushing the old beast would be a bit of a challenge.
Title: Re: Mpg?
Post by: McCrae72 on April 17, 2018, 07:32:44 PM
Now that’s a problem, I was told when I picked up my bike that I should believe the fuel gauge and if it said I was empty I would be. I really should take a can of fuel with me and run it dry and see how accurate it really is.

Post by: markis42 on April 17, 2018, 08:00:46 PM
Always get 200 plus miles from a tank where ever I go. Mostly two up with top box and Batzen screen set at middle height.
Its all about the right hand at the end of the day and I probably ride steadily compared to some others. Having said that that's possibly why I am still riding after 40 years.
Title: Re: Mpg?
Post by: vsteel on April 17, 2018, 10:19:39 PM
I seem to be filling up around the 190 mile mark and it is taking roughly 4.2 gallons (US).  There should be almost a gallon left in the tank if the specs are correct.

  I consistently can go 200 miles on a tank and have fuel left over.  Last tank on my Gen 3 I went something like 15 miles past "0" miles remaining and put in 4.7 gal.  This is consistent with my Gen 2 and also my 1050.  Basically, when it gets to one bar remaining, you've got one gallon left, ride/plan accordingly.

And yet, there have been a couple of postings over the years from people who have said that 0 miles displayed was literally the end of the road for them. In some ways, I wish that the miles to zero countdown could be turned off. I just find it misleading and stress-inducing.

Just select one of the other possible variables (odo, ave speed, inst fuel cons etc) when the display changes automatically to ‘range’. No-one forces you to watch it counting down to zero.

  I get that.  I'm the same way when I see that orange fuel light come on way too early.  Once it's on, my discomfort level goes up.  It's there for a reason, but it sure comes on early.

On my bike, the initial mileage remaining number always seems to be optimistic. Then, as the remaining mileage ticks down, it appears to be at a rate that is about double the actual mileage traveled. Next time it happens, I will take the initial countdown number and compare it against my average fuel consumption on the basis of 1 gallon remaining, and see how close it is.
Title: Re: Mpg?
Post by: CaptainTrips on April 20, 2018, 09:50:17 PM
Here is a followup to the miles remaining question. Today, I went out for a ride and planned a fuel stop halfway through. About 10 kms (6 miles) from the fuel stop, the warning came on and the displayed showed 65 kms (39 miles) remaining. I rode the 10 kms (6 miles) to the fuel stop, but the display still showed 61 kms (36.5 miles) remaining instead of  55 kms (33 miles) remaining.

So what does this mean? Well, on my bike, after the countdown to empty starts, the calculated mileage remaining isn't linear. It starts off over-estimating the mileage remaining and then as it gets closer to empty, it compensates by under-estimating mileage remaining, which means that miles to zero drop faster than actual miles traveled.

When I stopped for fuel, I put 15.65 ltr (4.13 US gallons) in the tank (20 ltr = US 5.28 gallons). That seems about right -- about 39 miles to the US gallon (combined city and hwy riding) which is typical for me in town.

Or the miles remaining value is responding to people changing their riding style 😊 once the light comes on how many people back off and start eking out the fuel left ?

Well, not me.  I ride conservatively 95% of the time and even more so when I am down to two bars on the fuel gauge.

Mine's similar to that. I've found that if I ride 'steady' after filling it right up the 'range to empty' will often show 260-270 miles, which I know I never get and it does seem to drop quicker once the tank is showing half.

That said, I usually fill up when the light comes on anyway (or soon after) but I've found that this means I'm usually putting about 15 litres in, so there's clearly plenty left. I also find it easy to average 50-55mpg (according to the bike) on long runs, sometimes it goes up around 60mpg but equally, if I'm out for a blast with friends it can drop to low 40's...

On a recent run down to Hereford (250 mile scenic version) I managed 49.5 UK mpg, 207miles on the trip meter and filled up with just shy of 19.5litres, not hanging about on the open road, but a fair bit of pootling around towns and villages, no motorways.

I usually get between 46-48 UK mpg, but a lot of that is shorter 20mile commuting to work  :028:

Post by: McCrae72 on May 06, 2018, 05:24:05 PM
Well I did the 12 min tune up, and I’ve also put the puig touring screen (which I hate) and I got 203 miles with 16.5 miles still showing on the fuel range. I think the bike is still loosening up as it’s still only done 2500 miles so I’m pretty confident that 200+ miles from a tank will be the norm, happy with that.

My 2016 XRX now has 14,000 miles on the clock and;

All with no aluminium Triumph panniers;

All solo or two up, does not seem to make a difference;


Average cross country bimbling 52-56mpg
Motorway work at 75mph, light winds 50-52mpg

With aluminium Triumph panniers fitted;
Average cross country bimbling 49-52mpg
Motorway work at 75mph, light winds 48-52mpg
European Motorway work at 85mph, strong winds 42-46mpg

I trust the miles left readout without question and the most miles per tank was 221 with it showing 0 left in the tank when I pulled into the petrol station close to my home.

I am getting 37.8 MPG on my 2017 TEX XRT.

Mileage seems to go up until I get on the freeway.  Freeway speeds of 80+ MPH really suck down the fuel.

On a recent trip home from the Moonshine Lunch Run, the weather turned cold (34 F) and I ran into stiff headwinds and crosswinds north of Indianapolis.  The mileage for that tank of fuel dropped to about 26.5 MPG.  I had to keep hauling a$$ to beat the sub-freezing temps and predicted snow/freezing rain.  In April.

Gen 1 - 60 mile a day commute, between 55 and 60mpg, I usually set cruise control at an indicated 70 on motorway, full use of the throttle when accelerating  :305:..... Well it is good fun...
