Are 300cc bikes good enough for highway driving nowadays? If not, help me choose a bike!

So let's keep it short. ALL I care about is reliability, longevity, and fuel economy. I'm sticking with Honda for that reason, I know they tend to be extremely reliable.

So, I have it narrowed down to a few bikes.

A new Honda CBR300R
A new Honda CB300R

A low mileage used Honda nc700 or nc750 if I can find one cheap enough.
A low-mileage Honda CB500X

or a low-mileage Honda CB500f

remember I only care about reliability, longevity, and fuel economy. I do not care if the engine size is small and I will not "outgrow" the bike. I'm an experienced rider of street bikes and have owned bigger bikes in the past. I no longer have a need for performance and just want a bike capable of adventure and getting me a really good MPG. This is why I'm going as low as 300cc. If modern 300cc bikes are capable of a lot of highway driving and long-distance I'll totally get a 300c because they would probably have the best mpg. My concern with a 300cc is a lot of highway mileage killing the bike in the long run. I could be totally wrong on that though. I'll also have paniers/luggage on the bike as well, probably nothing super heavy though.


Thoughts?

No, a 300 is not good for the highway. Honestly, motorcycles haven't gained any grunt as technology has advanced. The horsepower goes up as the RPM limits go up, but torque output stays the same for a certain displacement and engine configuration. Like a 30+ year old carbed 600 with a low redline has 45lb-ft of torque and a new fuel injected 600 with a 15,000+ RPM redline is still just 45lb-ft of torque.

Honestly, I don't know how much power you actually need to be totally safe and capable on the highway. I'm sure you could do it on the 300, but it wouldn't be comfortable or safe. I have a CB450 and even that kinda struggles to cruise at 80mph.

If you are doing highway riding and using panniers, I would personally go the 750. The 300 might struggle and not be able to give you the overtaking power that you might need in some situations.

Regarding "getting me a really good MPG" then go for a 100cc motorcycle. Point being, that everything is a trade off. You want something that gives you great MPG but that you can cruise at highways speeds comfortably with panniers - probably doesn't exist. But that also depends on what you call really good MPG.

I rode a 2017 NINJA 300 from the Missouri Ozarks to Tail of the Dragon. It's certainly doable, but I did have issues when I encountered any serious hills and/or head or crosswinds; the best I could get WOT was 75mph. Sure, that's enough to keep up most places, but I had nothing left to get away from an idiot. Bear in mind that I'm only 5'2" and probably 155-160lbs ATGATT. The other issue I had is that I couldn't get hard sidebags for it, just "semi-hard" . They came with a rain cover that you absolutely had to mess with if there was any more than a sprinkle.

On the upside, it was light and flickable and IRRC, I got around 58mpg around home, but managed 60+mpg in the higher elevations during my trip. I traded it for a 2018 NINJA 650 which gives me MORE than enough power for what I need and I was able to get real sidebags for it. I get around 53-55mpg.

But given that you're a Honda fan--and with good reason!!!--, you might see if you can score a nice low mileage NT700V. It's the little brother to the ST1100 and 1300. Integrated sidebags (bigger clamshell lids are out there; I bought mine new from the UK back in the day, as well as a lower fairing). The topcase was optional. Great sport tourer, more tourer than sport. It begs for a sixth gear, but other than that it performs well, plenty of power. My biggest issue was that it was always a little tall, wide, and top heavy for me (and it didn't come in green:giggle:). But I put around 35,000 miles on it before I sold it. I think I got in the low 50's mpg.

I'd be more inclined towards the CB300F or CB500F over the CB300R for the more upright ergonomics, which tends to be more comfortable over the long haul. A 300cc will get you on the freeway and will happily hum along, but it's nearing capacity of its performance, so you can't as easily flick the throttle to get around someone or out of trouble. Slowly passing a semi on a light weight motorcycle is not particularly fun. If you buy a lighter motorcycle it'll be great around town, but less so on the freeway. A more capable bike will be better on the freeway, but more ponderous a slower speeds. I guess it's all about what you're willing to accept.

I believe Yamaha is regularly cited as the top brand in terms of reliability. All Japanese brands are near the top, so perhaps widening your pool will open up more options. Something the Yamaha MT-03/MT-07 or Kawasaki Ninja400/Z400 might be worth a look too. Having more choices is a good thing these days when buying a motorcycle these days as there's little downward pressure on prices.

So I found a 2014 Honda Nc700 for a good price and it has 6k miles. He says the bike runs great and is in clean condition. I'm going to go check it out later

I think the nc700 is the best fit for what I need. I've read it's literally half of a honda fit car engine that's inside the bike. It's a low reving gas sipper that is big enough to get me where I need to go. I also love the styling.

Would you guys agree this is a good fit? I genuinelly might buy it. Do you think buying a 2014 is too old? It only has 6k miles and I can get it for 4500.00

I wanted a newer bike but 2014 isn't that old right? I've heard these bikes are very reliable and can last a really long time. being a 2014 scares me a little bit though.
6k isn't even broken in yet if the bike was cared for.

I'm pretty sure, based on the reviews I've read, that Honda had you in mind when they designed the NC700.
If you're looking for a comfortable mile eater, I think the NC700 is a good fit. 6,000 miles on a nine year old bike, less than 1,000 miles a year, would indicate to me that it sat for a while at some point or another. Rather than the age of it, I would be more concerned about how well it's been maintained. Having a bike sit can be good for the cosmetic condition, but bike that sit tend to rot. Tires crack, gas gets gunked up, seals go brittle, etc. The seller may have a bushel of records indicating they've cared for it well, but may just have pulled it out of the garage after an extended siesta. It's hard to tell by looking at it. This seemed like a good starting point for what to inspect when you go look at it.

This article on the bike you're considering is very favorable it says it's got plenty of torque great acceleration as long as you mind the red line which is less than half of what you find on the tach of a sport bike.

And it gets 64 miles to the gallon --at least that's what Honda claimed when they released this model in 2014.


The NC700 is about 5 inches shorter in wheelbase than my Honda Shadow, and weighs 120 pounds less than my bike,
so I would think it is a lot more maneuverable in the city or in other tight turning environments.

I ended up getting the nc700 however I just noticed on the way home the break and tail lights are out :(

the bike runs great however the engine sounds very strange.. almost tick/knock like. It scares me but after looking around people seem to say these bikes just sound weird at idle and I've found videos where it sounds pretty much the same as mine. Idk if to worry or not. The bike does look like it may have sat for some time outside. there are some rust spots down by the shifter and some of the bolts have a bit of rust. but I got the bike pretty cheap. Keep in mind I live in Florida right by the ocean as well. Rust is on everything.

Ok , now , down to the cleaning , polishing , tweaking , and adjusting .. Make it yours , and ,,,,
Send pics ... congrats .....
Brake light is a few cents. I would be giving it a thorough service. Replace all fluids (brakes/coolant/forks), lube cables, check valves, replace sparkplugs, change oil, replace air and oil filter, and check the age of the tyres. Sounds like a lot, but it can all be done in less than a day, and once done gives you peace of mind until the next service interval.
Congrats, post pics! Could it be a fuse? :unsure: I lost the brake light and blinikers on my Shadow once (can't remember if the taillight was out or not) that turned out to be a fuse.
so my break light/tail light was NOT working last night.

I was driving today and they were working? So it's clearly not a fuse issue? Why would they not work and then suddenly work? What would be causing this issue?
Also question on painting motorcycle fairings.

I want to change the color of my plastics on this bike. They are in good condition and the paint is not chipped. They are curretly red and I want to change them to a super dark purple or black. Could I do this with some kind of simple spray paint?
Probably a loose wire , bad connection , loose bulb , dirty contacts ... Krylon has paint for plastic , can't confirm if it's any good .....
