That doesn't sound too far off for gentle riding. But the speedo indicates you can take it all the way to 40 in 2nd and 55 in 3rd if you want to push it some more. That assumes no one has changed the sprockets to different gearing.

That's why I was wondering about this as a cruiser. The speedo gear "graph" and my actual gear selection are way off.

If I'm not accelerating, I'm in fifth at 35. Manual says not to go below that in fifth though.

The handlebars are rubber mounted to reduce vibration and should be loose enough that they can be flexed up or down slightly with effort. A lot of owners assume they are loose and tighten them up, which increases vibration to the rider's hands. The bar end weights also serve to absorb vibration, if they haven't been removed.

To see if it's the headlight buzzing, place your hand on it at speed. If the buzzing changes or stops, the noise is coming from the headlight.

Interesting. Except for it's mention of the indicators on the speedometer, my 2016 manual is completely silent on the subject of upshifting and downshifting speeds, or max/min cruising speeds in a given gear.

I'm beginning to think the 2016 owners manual is a "cliff notes" version of earlier years.

I'm repeating what another member of the forum posted some time back. Not sure what year his manual was from.

Harmful lugging of an engine can occur before it is perceptable. Whatever gear the bike is in, if it won't accelerate smoothly when given throttle, the speed is too low for that gear.

Buzzing - Mine was making a buzzing noise at lower rpm / lower speeds. So in my neighborhood, I would turn my head and it sounded like the license plate. I took some rubbery / foamy strips that I just happened to have and cut them to size and placed them on the back side of the plate where it would first touch the humps on the license plate holder. It stopped that rattle noise. But now there's another. Sounds like it is up front and not nearly as loud and annoying.


Speedo Marks - The gear marks on the speedo are suggested max speed per gear, with the stock gearing. It appears Honda made an effort to put those marks at such spots to yield the best possible acceleration of the bike. For example, it could rev on past those marks in each gear, but the hp / tq is dropping off past those spots and eventually the valves would float and lose a lot of power. Based on the hp/tq curve I saw on a youtube video of a Rebel on a dyno, it appears to stay in an rpm zone that has the most "area under the curve," the best place to shift is at those marks. Kudos to Honda for giving us those marks.


Sound of the Bike - Last thing, last night I was driving mine. And exactly at 60 mph (~7,000 rpm), the sound of the engine and exhaust sounded almost identical to something else I've heard. So as I was riding, I was thinking, "what is it, it sounds like?" Was it my lawnmower? No. Weedeater? No. My 3rd Gen RX-7? No. My truck? No. I couldn't figure out what it sounded like so I decided to just forget about it. Right after I decided to forget about it, a bell went off in my head, DING! It sounds almost exactly identical to my leaf blower! Other speeds it doesn't. But at 60 mph, it was uncanny how it sounded just like the leaf blower! I chuckled and enjoyed the rest of the ride.

I have to disagree with the statement that "the best place to shift is at those marks." Those are maximum shift speeds. Shifting strictly by the marks, the bike would be in fourth gear from 55 to 70 mph, and fifth wouldn't be needed until above 70 mph.

I agree completely... I would NEVER consider following those gear suggestions on the speedo. After riding a couple more hours today, I have found that I need to shift to third at 30,4th at 40 and 5th at 50 to get the best results. It WILL cruise along at 55 up to 65 with no problem in top gear, although I certainly wouldn't want to listen to that for a long cruise! 😀

I will say one other thing related to this bike being a real Cruiser. Besides deciding I do actually have enough power to suit the riding I will actually be doing in the real world, I am AMAZED at the difference installing my floorboards to replace the pegs has made... WOW! Like a totally different riding experience! Now at least I have more security in my decision on possibly keeping the Rebel and selling my 85 Shadow...

I've mentioned it many times on this board and the other (former) board: top gear works just fine at 31-35mph

"Ride Safe, Chop Safer" Motorcycles are not unsafe. However; they are extremely unforgiving of inattention, incompetence, ignorance, and stupidity.
Dismantling, sawzalling, and rattle canning does not make a bobber.
Those are STEPS toward customizing, not customizing unto itself.
