I'm no expert on engines or anything, but I gather that one thing that sets the CTX1300 apart from other motorcycles is its V-Four engine. Most motorcycles run on a V-Twin. I wanted to do some research to figure out what the benefits of a V-Four engine are when compared to the more common V-Twin. Here's what I found, and please let me know if this is correct, or if you think I missed something.



The main draw of a V-engine of any kind is its balance. Pistons trade energy with each other, instead of with the crankshaft. This results in the crank rotation more smoothly, and the rear tire being undisturbed by piston stop-and-start. A 90 degree V-engine requires the crankshaft to be far back in the chassis though, making it hard to get adequate weight on the front wheel. There are 60 degree V-engines that require more balance shafts but that doesn't really have to do with this comparison.

So what is different between a V-4 and a V-Twin engine? On another forum I'm told that V-4 engines offer a smoother ride than V-Twins and can make more power and torque with less displacement. The power delivery makes for more aggressive throttle input out of corners, in a package much smaller than an inline 4. Is this true?

It seems that Honda in the 80s thought that V4's would be the way of the future. These engines were to produce awesome top end power in a narrow platform, and it lent itself well to handling too. It seems the issue was simply the buying public's preference for V-Twins and I4 configurations. This could possibly be due to the fact that V-Four are generally put in bigger and heavier bikes.

So from what I have read it seems that the more pistons you get involved the smoother the ride will be. V-Fours are obviously bigger and more awkward to fit into bikes, but they do generate a lot of power.

What would you say to someone who is trying to figure out what type of engine would be best for them? Do the things I've written about above apply to the CTX1300's V-Four engine?

Boy do I expect this thread to be busy! :) Engine configurations will greatly depend on the intent of the bike and the attitude of the rider. I am on my 3rd V4 engined bike and love the flat torque curve characteristics. For the most part it is the best of all worlds regarding torque, roll on power, forgiving when you've chosen the wrong gear, smoothness... you name it.


My past bikes:
-Parallel twin (1)
-V4 (3)
-V Twin (2)
-Inline 4 (3)
-Single cyl (1)

A couple of points I'd like to throw in here --

First, it was mostly rider preference that led to the majority of bigger bikes -- at least cruisers -- to be V-twins. Harley started it, most cruisers are Harley's, they have a distinctive rumble, and most cruiser riders wanted that same experience. That pretty much led to the demise of the original Valkyrie and last-gen Magna.

But there was/is also cost to consider -- cc for cc, twins are cheaper to produce than 4's. All this contributed to the mass majority of cruisers being twins.

But, all the points you raise are correct -- more cylinders do generally make more power per displacement, to a point. And without question they are smoother. For those reasons, I personally prefer a V-4 over a twin. I have ridden V-4's in three different configurations now, and I have been itching for years for Honda to put one into this exact kind of application.

As for what would be the best for you, only you can make that choice. Large displacement twins will generally give you more off the line, bottom-end pulling torque, at the expense of top-end flat-out horsepower. Hence many are referred to as 'stump-pullers'. Smaller displacement and multiple cylinders tend to be tuned more for higher top-end horsepower at the expense of bottom-end torque. Note that I said 'tend to be', as it appears Honda has tried to break that mold by tuning the CTX1300 for more low-end torque and less top-end hp. We haven't yet seen it run through the wringer, so no one has been able to really give a good real-world comparison of it next to other cruisers, or even the ST1300 from which the motor has been graciously donated.

All I can suggest is to either try to get test rides from a dealer, or find some really good friends with different types of bikes who would let you take them out to see the differences for yourself. That's the only way to know for sure, and even then sometimes you need to ride different styles for a few years before you decide what fits you best.

Good luck in your quest!

Have any of you guys heard of the Motus Motorcycle?? It features a V4, 100 horse motor,similar to Honda's V4,but REALLY SCREAMS.I don't particularly care for the bike itself,but that V4 motor is somethin else!! Check it out and see what you think! Dave!!!

I have heard of the Motus. VERY pricey bike. Other than a longitudinally mounted v4 I really see no resemblance to the CTX in spite of what some others have said about it being the same. It is a different style ride, different bike ergonomics, different intended rider, and MUCH different price! :eek:

Yep, two wheels and the longitudinal V-4 are the only things these two bikes have in common. I don't know why people insist on trying to compare them, because they are totally different classes. The Motus vs. the ST, now that's another story ...

The thing that jumped out at me regarding the Motus V4 motor is,it makes something like 125HP,but uses the old school push rod/rocker valve train system,verses the shim over bucket systems used on most of the machines built today.

And again,I am NOT comparing motorcycles.I was only tryin to point out another V4 motor,which has big HP,yet uses old technology,nothing more,and nothing less. Dave!!

Well, remember, this same motor in the CTX cranks out 125 hp in the ST. All a matter of how it's set up for specific applications. The Motus is almost all sport bike, with some touring capabilities thrown on. The CTX is, well, we know what the CTX is already.

One of the real appeals of the CTX1300, to me anyway, is that there really isn't anything else out there you can directly compare it to. Honda really has blurred the lines this time.

I agree with you Ed.;)What I'm gettin at is how Motus has achieved this big HP in their V4 motor using old school valve train technology.[push rods :eek:] If ya know motors [I've tinkered with one or two in my time:rolleyes:] ,and with the exception of the HD,everyone else uses the shim over bucket system in their motors.[overhead cam,less moving parts,equals increased HP] :)Dave!!!

I agree completely. In the Motorcycle.com video, the reporter was having a hard time trying to describe what the CTX1300 was, what category it fit into. That makes me think that Honda's description of this bike as "an entirely new motorcycle species" isn't just a clever marketing phrase. I think of it as a mini Gold Wing in some ways, since it has a lot of the characteristics of that bike, but it is also quite sporty and has some cruiser qualities as well. I like it because it's NOT just a copy of something else from another manufacturer.

All reasons I like it too. When I sold my GW I wanted some just like it but smaller and easier to manage in tight places like parking lots and city streets since that was where most of my daily riding happened. I tried the Burgman 650 (1/3 GoldWing) and that was great at close quarters riding but not as good as I wanted at LD riding. It did do ok at it, just as good as I wanted. Then I found the ST1100 (2/3 GoldWing). Nothing else was available at the time that was quite like it. Sure there were other ST style bikes but all the others leaned to sport and the ST1100 leaned to touring... where I want to be. There is still something missing with the ST1100. Foot position is ok but just a bit back from where I prefer. I looked at the ST1300, but that was more sport than I could handle for very long so that was out. Then Honda brings this CTX1300 (still 2/3 GoldWing). There is nothing like it available yet. It's a class by itself. I just gotta go ride one when it's available locally.

The reason I came here was to learn as much as I could about the CTX as it is a new model.I have been considering another machine similar to the CTX,but had a bad experience road testing the first one I drove due to dealer incompetence.[it was NOT prepped correctly] So I decided to also consider other makes/models and the CTX happened to be one of em,especially,since it's brand new.But since I still haven't physically shaken hands with one yet,let alone drive one,I have been tryin to form an opinion based on what I read here from the membership's experiences which are FINALLY coming to lite as more and more CTX's are being delivered.So far,I hear some good things about this machine,and I hear some not so good things about this machine.But it's still early yet and all the votes aren't in.So keep up the good work,especially,the reports on your likes and dislikes. And I thank you for puttin up with me! Dave!!!

I have another question for you ladies and gentlemen who now have this machine.Would it be possible to keep track of your fuel mileage and post your results here?? It's nice to know just how good or bad a new machine is on fuel.Thank you. Dave!!!

Hey Dave, also check out fuelly, they have a moto section as well. Here is a link to all the Honda motos on there, no CTX1300 yet however...

Thank you sir.I checked out the ST1300 [like you said,no CTX1300 yet] to kinda get an idea and after reading how much the mileage varied,I'd say it all depends on how ya drive it.So I'm guessin 50mpg would not be out of the question if ya drive it easy.Thank you again. Dave!!!

No worries Dave!

Agreed, I'm anxious to hear back from anyone who does a long distance cruise with relatively steady state speeds. However I do wonder what the dimished HP numbers vs the ST will do to econ especially when you consider CTX1300 tips the scales at 734 lbs (750 Del.) and ST is at 730 lbs...

I really don't think the weight difference between the two machines will make that much difference.Good fuel mileage depends on your right wrist action.Twist it hard,poor mileage.Twist it easy,good mileage.Dave!!!
