I'm an experienced rider. I presently own the FZ-07 and have owned a 2013 and a 2014 Ninja 300 among many other bikes. After the wet roads dried up, I took the CB300F for the first ride.


It's a great little bike. Sounds as good if not better than my FZ-07. It's louder for sure and louder than the Ninja 300 which sounds very much like the Ninja 250r. I probably will keep the Honda exhaust stock. I owned a Grom as well a couple of months ago and was expecting the CB300F to vibrate something like that, but it doesn't. In fact, it's almost as smooth as the in-line twin FZ-07. Vibration is slightly more than the Ninja 300 as you would expect with a thumper. Acceleration is hard to compare, but the Honda feels a little faster than the Kawi to me through the first 4-5 gears to about 60 mph. By that I mean it is easier to accelerate faster with the Honda without trying to drag race. Part of that is that 1st gear on the Ninja 300 is almost useless unless you are in bumper to bumper walking speed traffic, then it's good, but the Honda would be just as good. It's just that the Ninja 1st gear is really short. The very tall 6th gear makes up for that on the highway. It's like an overdrive.


Could be the Honda's lighter weight more than makes up for the smaller displacement comparing it to the acceleration of the Ninja 300. At interstate highway speeds, the Ninja 300 is the better of the two. I know top speed will be better on the Ninja. The Honda 300F doesn't hug the road quite as well (maybe the CB300R does though) and seems to be working a bit harder. It's still fine, but I have to give the edge to the Ninja 300 there as you would expect with a larger engine, fairings and a fly screen. In town, the edge goes to the Honda 300. I took the bike briefly up to 85 mph. At 70, rpms were 7200, and at 80 rpms were at 8200 rpms. Roll-on is so-so in 6th gear, again the Ninja 300 roll-on is better there. Certainly if you ride over 75 mph, you would probably do better with the Ninja than the CB300f. No windscreen might be part of that. The little fly screen on the Ninja 300 really works.


The 300F rear brake is so-so as was pointed out. Suspension feels pretty good. Clutch is smooth and quiet. I will need to adjust my kick stand. The bike is almost straight up with the kick stand down.


What I like most about this bike is how easy it is to move around inside the garage and when riding on curves. That 348 lbs. wet is HUGE! The 2014 Ninja 300 I had was 386 lbs with ABS. Without ABS it's 379 which is still 30 lbs. heavier than the CB300f. You don't notice that so much while riding, but you sure notice it moving bikes in and out of the garage.


The Honda CB300f is just a very good all-around bike, but excels in town and roads up to 65 mph or so. I don't do that much freeway riding, but I would not be afraid to ride the CB300f at 75 mph all day long. The engine would be working a little harder than the Ninja 300 at that speed is all. I will be interested to hear someone compare the Ninja 300 to the CB300r for higher speed riding.


I prefer the lighter Honda over the Ninja 300 since I do mostly in-town riding with maybe 10 miles of interstate a week, but I think if I mostly rode interstates, I would go with the Ninja 300. I can't comment on aggressive riding in the twisties yet. Both bikes are going to be very good there.


Seat ht., foot peg position, clutch pull, handlebar position are slightly different on the Ninja 300 and the CB300F, but they are so close that you don't really notice much difference after a couple of minutes in the seat.


All around, I think most people would prefer the Ninja 300 due to better performance at higher speeds and the race bike look. Just not as many people seem to prefer the naked bikes. Whether the Ninja is $1000 better is another question. I actually prefer naked bikes and really prefer light-weight bikes, so provided the Honda 300F was capable of 85 mph safely, accelerated at least as well as the Ninja (the one weakness of the Ninja), and didn't vibrate too much, I was going to be happy with the bike...and I am.

Nice review! Those are all the exact reasons I want the 300f. I want a great commuter bike around town but be able to get out of town if needed without pushing it too hard. 55-65MPH roads is what I will stick to if I do head out of town too. Plus the MPGs and the Price of the 300F are absolute steals. The only thing I may hold out for is a color other than red and possible addition of ABS.

It wouldn't surprise me if Kawasaki came out with a naked 300 bike next year too, so you might have additional choices in the 2016 models. Kind of weird to only have one color. You see 2 colors a lot, but I can't remember a bike being offered in only one color. It is a nice red color though, the Honda red, I guess. Exactly the same shade of red as my FZ-07. Kawasaki always has at least 2 colors...Kawa green plus something else, usually 2 additional colors when they bring out new bikes.


The CB300F is going to be popular with female riders I think due to the light weight and lower seat ht. There is even a lower seat option.


You know the Grom is a fun little (225 lbs. wet) bike. It won't go 65 mph, but it will do 60 mph. Very easy to work on too. Comes in red and black for 2014, but new colors for 2015 coming out soon. 110 mpg. If fuel economy is your thing, this is THE bike. Loads of fun. It has the exact same dashboard display as the CB300F. The slower speed, very hard seat, and vibration are about the only distractions from the otherwise brilliant bike. People notice you on a Grom and want to ask about it.

Thanks for the tips. Had the Grom already and loved it but it didn't do it for me. I need to get up to speed to be able to get out of town at times. That seat sucked after about 45 minutes too. If I could afford it I would have kept it for around town only.

Thanks for your great post AJ Nin. I really enjoyed reading it. I'm sold on the Honda CB300F. Almost all my riding is done on secondary roads. It's no fun for me to ride 75 MPH. My wife loves riding with me but she does not enjoy going at high speeds. We can ride 50MPH to 60MPH all day and it would not bother us. I don't even take my car on the freeways anymore. Just to many crazy drivers. You said the CB300F gets 110MPG? You sure about that? With that milage I can afford to get motel rooms for my wife and I. hehe I hope I can find a dealer that will let me take one for a ride before I but it. Ride safe my friend. If you can figure out some way to get rid of this snow in Michigan please let me know.

I have the 300r, broken in by now with 1500miles. I always calculate my MPG just as a game to try and beat it next time. I do however run it pretty fast. Fast accelerations, I look for nice curvey roads. The best MPG I have gotten was 95mpg. About 15-20 more than what Honda states. I have done a lot of mods also tho. Lightened it up quite a bit and a nice flowing exhaust, air filter, synthetic oil filter and Amsoil synthetic oil. I think that's a pretty darn good MPG for the R.

You could get more by changing your sprockets to the max the CB300 can take (15/34t).
Though I can't speak for a CB300F yet, my Honda Rebel normally takes 10W40 oil, but I found it works better in Hot South Florida, with a few oz of 5W30 in it. It runs smoother, and MPG goes up. So does top speed.

I recently changed that 5W30 to 5W30 Dexos oil, and it's a huge improvement over synthetic or regular motor oil!
It seems 5W30 Dexos oil gives me less clutch slip, yet runs the engine smoother than any other oil!

Right now I do between 2 to 3k miles on my oil, whereas before I did half of the miles on it before I needed an oil change.
The Rebel doesn't have an oil filter.


I'm still in test phase, running 2 stroke oil in my fuel, at a ratio of between 100:1 to 200:1 (160:1 being the sweet spot), and it seems to work great on a 4 stroke!
No plug fouling whatsoever yet, and I've logged over 4k miles on the bike doing that (9k before I started testing with fuel oils)!
I might later on change to cheaper oils, and see how they run.
Better mpg's at lower speed, better top speed; I'm also running the engine quite a lot at 4-6k rpm.
I know my lawnmower (aka test subject) didn't like engine oil in the fuel as much, as it was running less good than with regular fuel (as opposed to it running better when adding 2 stroke fuel); so I'm not even going to try running my bike with engine oil in the fuel; however I did find that the bike also runs better with octane booster; an oil based lubricant, that seems to me overpriced 2 stroke oil without as many chemicals in it.
But also running with engine oil there was very little, to no plug fouling going on.

So far, I can recommend adding 2 stroke oil to a 4 stroker's fuel tank, at 160:1 ratio; if your aim is either improving performance, or improving MPG. Also, supposedly, improving lifetime of the engine.
You're not particularly improving your wallet doing this, as at a 160:1 ratio of oil in the fuel, you're paying about 20% more on fuel, but it should be offset by paying 2oz less fuel per tank, and by having about a 5-10% better MPG, meaning you'll go 5-10% further on a tank.
Financially, you should lose about 5% on the whole, but it does give you the benefit of adding top speed performance and potentially engine life!

Thanks for the review. At the same time I'm not sure it's comparing apples to apples. They serve different styles/needs, IMO.
When I visited a Kawi dealership, I checked the clutch on a Ninja 300 and couldn't believe how light it was - quite lighter than on the CB300FA.

Very nice to hear your positive comments on the F. I am waffling with my 300F purchase before year-end and that is 1) possibility of a price-right FZ-03 and 2) local sell-out of '15 300F's (although a few 'like new' used are cropping up). Your comments about acceleration up to speed-limit makes my happiness with the Honda more the first place choice. I totally regret the situation here in Phoenix where one must purchase without having ridden. Test rides are unheard of and I do not know a friend that rides 300-class bikes. Yes, I have seat-of-pants experience with 100+ machines of all sizes and vintage, and would be fine with even a 250, but this next choice must be from analytic selection and less from the heart. If it must be ride-unexperienced, then this forum is most helpful so thank you.

nice weather for us now, average weather for every other state. but in the summer..definitely a 10w-40
Depends,
The rebel is aircooled, and for such small engines you can go lighter.
I think vibration should be the indicator. More vibration means lighter oils.
There's a sweet spot. Too light engine oils, and vibrations increase again.
Especially when the bike is still new, lighter oils are better.
I never ran into problems with 5w30 and 10w40 mixed to a 1/3 ratio on my Rebel.
The f and r are liquid cooled, I believe?

I wonder what would happen if you change the radiator coolant with oil?
Better for the pump, and I'm expecting the bike to run fine even without coolant (although with slightly hotter temperatures, probably on premium fuels).
Not saying I recommend riding it without cooling, but saying that replacing radiator coolant woth low viscosity oil might be better for the bike.
Lighter in weight, better for the pump, and the engine would probably rise in temp by only a few degrees.
The Suzuki S40, Yamaha SR400, Honda Rebel 250 all run aircooled, though on lower compression ratios.

While radiator fluid may be heavier than oil, it's less viscous than motor oil especially at lower temps and that might more than make up for any ease of pumping, but I don't know for sure. I know several bikes like Harley Davidson have oil as a coolant, but those bikes seem to overheat and run pretty hot. My neighbor just idling and talking with me on his Harley after a couple minutes started to run hot and sounded kind of funny too. I much prefer radiators to air-cooled engines.

I love my 300F! I had a grom which was a fun bike to ride, but after awhile needed more so moved up to a 2016 300F. Its a awesome bike. And I have the lower seat option, which allows me to almost touch flat footed, which is perfect. The lower seat also has a carbon fiber wrap which looks much sportier than the original seat! I couldn't say enough great things about this bike. I love the way it handles and it being a lighter bike is a must for me, and there is absolutely no vibration, extremely comfortable and has the sportbike feel to it. Definitely has the power and torque when needed. I went for a 100 mile ride the other day and it was very comfortable! :)

Yes, too many people have bikes that are too tall for them especially with sport bikes. I see lots of people who can only touch the ground with the tips of their toes which can be dangerous. People think it will be OK, then they have to stop on a hill or even a little dip in the road or a shoulder and suddenly the toe doesn't touch. Just backing up is much harder if your feet barely touch. Or they stop and lean the bike to the side which is unstable if you happen to stop on loose gravel, etc, you can drop the bike. It's amazing when you look at all the Asian people who are short and the fact most of the bikes come from Asia. You would think they'd have more bikes with low seats. Even scooters often have tall seats, but you can usually hop forward off the seat to touch the ground if need be. Honda was smart to offer the lower seat option for the CB300F. I hope they sell a lot of CB300Fs so the model will be around a long time in case I want to trade for a new one.

I notice the new Kawasaki Z125, that looks like the Grom has a seat ht. of 31.7 in. compared to the Grom seat ht. of 29.7 in. 32" is my cutoff, but I much prefer shorter seats. The CB300F standard seat ht. feels like it was designed with me in mind. I'm 5'7". Seat ht. and curb weight are the first two specs I look for. Even 20 lbs. weight is very noticeable in the handling and moving the bike around by hand.

Seat height specs can be misleading. FZ6R is 30.9" and R3 is 30.7", but I assure you the R3 is worlds easier to get feet down. Seat width, foam depth, suspension squat, peg location.

As a kid, I couldn't get my feet on the ground of my bicycle.
Then again, we learned to come to a stop, and fall to one side.
never had a problem with it.
Even on a bike, it's not that hard, to have 1 or 2 inches shorter legs than the seat height.

That's great to see you are so happy and excited with it. It is a good bike all around.
