I get right around 55mpg

 

About 49 mpg consistently. So, three gallons gets me a little under 150 miles. I find I need to stop that often anyway on a long trip, to take a brief rest, use the restroom, get a drink, etc. So I don't feel constrained by the tank.

 

I know it all depends on how heavy the right hand is, and the type of topography that you're riding, both are some pretty good mpg's. Thanks for the replies.

 

I used to get around 155 miles to the tankful and the low fuel light came on with around 35 miles left to go.

I'm with you though. All my other bikes, including the T120 had bigger tanks. That being said, don't let the smaller tank be a deal breaker. The new Speedmaster is a great bike.

 

Blusideupp is on the money - getting about 120 miles in the seat before light comes on and squeezing 2.2 gallons back into the tank. Put 1700 miles on the bike now and I have to say the tank size is about right for what the Speedmaster is. I use mine for mixed commute/pleasure riding and love it for that but can’t see wanting to do more than 2hrs at interstate speeds without a wind screen.

 

According to the meter, I have averaged 61mpg (Imperial) over c4,000 miles. I am getting a range of c160-180 miles per tank,

 

After a 2800 mile trip I averaged 52.7 MPG total for the overall trip. 80% on secondary roads, 20% on Highways.I did carry a 1500 Liter bottle with me just in case but never used it.

I have a 2018 Speedmaster.

Over the last 1,000 or so miles I have averaged 68mpg on my 2018 Speedmaster.

Different bits and pieces on the speedmaster is a nod from the company to past models I reckon,
The head light shell resembles a 50's model nacelle(?) the battery cover nods back,the fuel tank I think is the same size as the US version 750 bonneville of the 70's......the more you look the more you see.
I'm coming off a harley with a 6 gallon tank with some decent fuel range,but I always stopped around every 170 kilometers (100 miles) to stretch my back,so the SM fuel range suits me....The speedmaster is a ripper of a bike

 

I am averaging over 60 MPG with 3000 miles on the odometer.

 

I have about 12,500 miles on my speedmaster and wish I had a bigger tank for sure. I would purchase one if triumph sold one. It is not just stopping every 150 miles but sometimes I am in areas that don't have many gas stations. See attached for fuel study.

 

I do find it slightly annoying having such a relatively small tank. I don't ever remember thinking about gas as much as I do now. But dang, I do love the bike!

 

I get about 40 mpg on my 2022 and that's being generous if I don't run the tank bone dry. And if I fill too close to the inner bracket, it overflows onto my tank. Almost got gas whipping into my eye. I can't get 100 miles out of a tank.

 

Depends on my right wrist. If I'm into the thrill of speed, then I'm getting about 50-54mpg. But if I'm showing restraint and have it on cruise at 65-70 for a long trip, I'll get slightly over 58mpg. So basically, over 4000 miles and a year with the 2021 bike, I consistently see 150-165 miles a tank before filling up.

It's right on time for when I'm ready to get off the bike and stretch for a bit. DBrian

 

My 2022 Speedmaster (9000 miles) is about the same. 53\54 in town & 58\59 road cruising. That's with being easy on the throttle + FL. straight & flat roads.

 

Yeah, that was a concern of mine as well, coming from a bmw 1200gs. But 1k miles into it and I’m getting about 56mpg. By switching ride modes you can get another 10miles per tank or so I’ve found. Also, when the light comes on and I go to fill up im only putting in about 2-2.4 gallons on average I think one time I put in 2.8 gal. I’m going to carry some fuel next time I’m close to filling up and see how many miles I can actually go, to get a base.

 

If you take some extra fuel, let us know how far you can go after that fuel light goes on before the gas is bone dry.

The fuel lamp goes on in my bike exactly whenI my readout shows 30 miles of range remaining. But I think it's actually more, like maybe 45 miles? That's because when I've filled up shortly after the light goes on, I put about 2 gallons in the tank. That means there's still 1.1 gallon left in the tank... which should get me over 40 miles easily. Looking forward to your findings! Thanks, DBrianb

 

I've made over 12K miles with my speedy these last months. Driving 60-70% highways (mostly 65-75 mph speed) /30-40% suburban/low speed roads.

I get an average of 50-51 MPG.

 

A bit late to this but I was also concerned about the tank size. Cruising between 60-70 the computer reckons on 170-180 miles from a tank. That suits me as I'll want to stop after a couple of hours anyway. What is worrying is the consumption at town speeds. The computer is then showing maybe 110 miles and that's not good.

It's a brilliant bike though but as someone said earlier, I'd buy a bigger tank if they made one.

110 miles all at town speeds. Poor you!

 

Dickenbacker, if you're in town at slow speeds, I've heard that switching to rain mode can up the mileage. You should still get close to 50 mpg even in town. At least that's been my experience.

 

Thanks, I'll give that a go (when the ice and snow have gone )

 

I dont understand Triumph going with smaller and smaller fuel tanks over the last few years. I like to keep going, not stopping every 100 miles to fill up, especially if I'm doing a trip.

 

I agree... even a 3.5 gallon (13 1/4 liters) would be nice, and I doubt it would change the slimness of the tank profile by much.

That said, I haven't had a problem, even on a highway trip out to eastern Oregon where gas stations are not that common. However, I did look on the map beforehand so I could manage my fill-ups. I figured 150 miles a tank. But facing a fierce headwind, the "miles to empty number" indicator dropped precipitously to single digits-- at which point I found a gas station a little earlier than planned.

Maybe Triumph thought no one would tour on the Speedmaster?

Here's my idea.. With everything getting more and more customized, why can't Triumph offer a choice of two tanks-- the standard 3 gallon or a larger 4 gallon when you purchase the bike? Besides, back in the '60s, Triumph had different sized tanks for the Euro and the US markets. (US tanks were slimmer). Happy Trails, DBrian

I bought a 1976 T140V Bonneville new, it had the English/Euro tank that was 4 Imperial gallons, I think the US version was 3 or 3.2 gallons at the time.

 

Jesus, I agree... it seems because they designed the Speedmaster off the Bobber that some of the more minimal features were kept. That Wunderkind tank would look good on the Speedmaster, not to mention the improvement in functionality! But I believe it's rather expensive. If a painted larger version came from the factory--with a refund for exchanging it with the existing smaller tank--that would be ideal. But I wouldn't hold my breath on that. We're just lucky they didn't keep that tiny tank that was on the original Bobber

 

Triumph was doing 2 different versions of the fuel tanks for the 750 Bonneville in 1976, as I said the bike I bought had the larger tank that held 4 UK gallons , the US import Bonneville had the smaller US 3.2 gallon tank, that is very similar style to the 2018 plus Speedmaster tank....Apologies, I didn't intend to hijack this thread

 

Hi Jeff, your point is well taken. Back in the 60s, US and Euro Bonnevilles had different sized tanks. But depending on the market where you lived, you didn't have a choice. There were times when the American dealers had input on the design, but not too much. Basically, you had to take the bike for that marketplace.

Nowadays, however, with so much customization on the Bonnevilles, I don't see why Triumph couldn't offer the bike with a choice of a large or slim tank. Even if it cost a little more, I think many would choose the larger tank. Or, it could be offered as an aftermarket accessory. Triumph are you listening
