Okay, let’s talk about this Honda XR150L and its fuel mileage, the MPG. I’d been hearing things, seeing numbers, but I always like to figure stuff out for myself, you know? Real-world use, not just what the brochures say.

My Process: Finding the Real MPG
So, the first thing I did after getting my hands on this XR150L was run it down near empty, just riding it normally for a bit. Then, headed straight to the gas station. I wanted a proper baseline.
Filled that tank right up. It’s not huge, maybe around 2.8 gallons, give or take a smidge. I made sure to fill it consistently each time later, stopping at the same point in the neck.
Right after filling up, I did the crucial step: reset the trip meter. Gotta know how far you actually go on that tank, right? Simple stuff.
Riding It Like I Own It
Then came the fun part – just riding the thing. I didn’t baby it, but I didn’t thrash it either. My riding was a mix of things:
- Commuting around town, lots of stop-and-go.
- Some cruising on back roads, keeping a steady speed.
- A little bit of light trail stuff, dirt roads mostly, nothing too crazy.
Basically, how I’d normally use a bike like this. It felt solid, reliable, typical Honda feel. That electric start is pretty convenient too, gotta say.

Tracking and Calculating
I ran through a few tanks this way. Each time it got low, I’d head back to the pump.
Here’s what I recorded each time:
- The miles shown on the trip meter just before refueling.
- The exact amount of gas I put in to fill it back up.
The math is dead simple: Miles driven / Gallons used = MPG.
I did this several times to get a decent average, smoothing out any single weird tank.
What I Found Out
So, after all that riding and tracking, where did I land?

Consistently, I was getting somewhere between 85 and 95 MPG. Sometimes a little lower if I was heavy on the throttle in town, sometimes a bit higher on steady cruises.
Is it the crazy high numbers some people throw around? Maybe not exactly, but hitting close to 90 MPG in mixed, real-world riding is pretty darn good in my book. It’s definitely efficient. You can ride quite a long way on that small tank.
Bottom line: It sips fuel. For a bike that’s easy to handle, reliable, and can take you pretty much anywhere sensible, getting that kind of mileage makes it incredibly cheap to run day-to-day. It just works, and it doesn’t cost much at the pump. That’s been my experience.
