What is engine lugging?

Question about lugging the engine! When I ride normally I usually shift between 4.5k-6k rpm(unless the engine is cold then I do it around 4k-4.5k).

However if I'm cruising around 50-55km/h or so I do it I third gear which will usually be around 3.5k-4k rpm.

Is that lugging the engine? Or would lugging it be riding like 2.5k rpm and trying to accelerate out of the low rpms?

The second one - loping along @ little more than an idle, then trying to accelerate quickly, without a downshift - or attempting a long, steep grade, without a downshift, is lugging.
Different power bands and torque ratings can make a difference. When I switched from a flat six cylinder Gold Wing, to v-twins (with a lower power band), I noticed I was spoiled to throttling up (w/o an upshift) out of a cruise, or up a steep grade. I noticed the V-twin (Harleys and big twin Vulcans) needed a downshift to accelerate similarly, out of the same low rpm cruise. I adjusted my riding style, but only slightly. I had to downshift a Gold Wing, occasionally - just not as much as I do on my big twins. In past, I did have higher reving v-twins (Virago, C-50, & Vrod) that didn't have that same degree of lugging, but you rode at a higher engine speed, so it is relative to the power band.
I doesn't sound like you are lugging, though. I admit that I tend to just lope along these days!

Oh yeah, gear ratios make a difference, too. A guy I know says his Indian Chief needs downshifts less than I do on my Voyager. I'm thinking his top gear may be different than my Vulcan's. Either that - or I just like downshifting and revving too much!

Thanks for your post! Definitely makes more sense to me now. I guess an indicator of it lugging would also be the bike feeling like it's stalling hey?

But yeah lots of down shifting is definitely one of the most fun ways of riding! What kind of Vulcan do you have, one of the 900s?

I currently ride a Voyager 1700ABS. It's a nice 2-up tourer, but heavy (895 lb.s). Smooth ride for those highway cruises with Wifey.

I have owned several Vulcans over the years, along with other makes and sizes. We have talked about trying a 900 for awhile (I had a couple of Suzuki C-50's before, and always was curious about the Vulcan 900). For now though, we run the Voyager and an '08 Harley Heritage Softail. Wife wants to keep that-it is a nice cruiser.

One indicator of lugging would be low engine speed with lots of throttle input and little acceleration. This can of course vary wildly from different bike with different engines. A crotch rocket in 6th gear at 50mph might be lugging it if you give it a lot of throttle. Conversely, I have a V2K and while the engine is basically impossible to lug, the transmission can chatter a bit if you open it up at 35-40mph in 5th gear. That being said, it still goes and fairly quickly, I don't have tach on it so I'm not sure exactly what it's spinning at those road speeds but it's certainly under 2000rpm.

Light93, what are you riding? The pic looks like it might be a VN900, but too small to be sure. Anyway, I rode a 900 Custom for ten years and that bike would run in 5th gear from 35 to 105 mph. I would need to downshift to accelerate (from 35-40), or climb a hill so if I was riding around town I would stay in 4th and downshift as necessary. But I never felt that engine lug in those ranges.

EDIT: after posting I realized I was in the 650S forum so none of that applies. Happy Riding!
