2015 Honda CB300F

Honda CB300F

The Honda CB300F is the newest 300cc model to be released for the US market featuring higher handlebars, upright riding position and a naked faring design. The Honda CB300F has no side fairings which results in a light weight and peppy handling single cylinder motorcycle. For a more relaxed ride the Honda CB300F has higher bars than its sportbike counterpart and features the same 300cc (actually 286cc) single cylinder counterbalanced engine, fuel injection, dual overhead cams and 6 speed gearbox.

The Honda CB300F has been announced in the US.

The Honda CB300F has a thin, agile profile and can be easily flung around and is actually lighter than it's sportbike counterpart because of it's fairingless naked design.

With a low seat height the Honda CB300F is accomodating to a wide variety of riders giving it a low center of gravity for great handling on city streets and curvy mountainous roads.

The Honda CB300F 's fuel tank is slim and provides great ergonomics and a very lightweight feel to the overall handling of the bike. While the CB300F 's engine delivers loads of low end torque and a smooth top end offering the rider flexibility for commutes or weekend rampages in the twisty stuff. The Honda CB300F has a very tame and easily controlled powerband, but can also be pushed for faster speeds while feeling confident in the corners.

Honda CB300F vs CBR 250 Top Speed Test

So how does the Honda CB300F top speed compare to the earlier released CBR 250 top speed you may ask? Well the Honda CB300F has the same engine as the CBR300 which has a higher top speed of 169kph sitting upright (175ish kph crouched) and offers 31 horsepower. Thats up from the CBR 250's 155kph upright top speed (165kph crouched) with 26 horsepower. But since the Honda CB300F has no windshield, you can expect the Honda CB300F to have a top speed of around 165kph for both sitting upright and crouched, it wont make much difference since there is no windshield or fairings to divert the wind around you.The Honda CB300F is more city commuter friendly because it has higher handle bars.

Honda CB300F Dyno

The dyno chart below is a comparison between the engines that are in both the CB300F and CBR300 compared to the CBR250, the Honda CB300F has the same engine as the Honda CBR300R, so its safe to say the power output should be smiliar. The dyno readings are straight from Honda Thailand.

Honda CB300F vs Ninja 300 Top Speed Test

In the Honda CB300F vs Ninja 300 acceleration and top speed test video below, the Honda CB300F is about 10kph slower than the Ninja 300. This really isn't too bad. The Ninja 300 has a claimed 39 hp vs the 31 hp for the Honda CB300F, in a real world situation the Honda CB300F rider simply has to crouch down too keep toe to toe with the Ninja 300 (but what if the Ninja 300 rider crouches down too). But since the Honda CB300F has no windshield, it loses on aerodynamics and will have more drag. On the low end however the CB300F should leap ahead. With minor modifications like freer flowing exhaust, air filter, roller chain and lighter tires the Honda CB300F should be able to keep the same pace with the Ninja 300, also when you remove the rear fender of the Honda CB300F acceleration is greatly increased, the rear fender is like an airscoop. With these observations, the Honda CB300F is indeed a serious threat to the Ninja 300 with the revised engine modifications.

If you observe the video of the Honda rider around 145kph, the ninja starts to climb away, but then the Honda starts to regain speed, where the Ninja 300 starts to fall off around 165kph, this is absolutely a partial fault of the rear fender adding wind resistance (tail tidy!). The test rider on the Honda also appears to be holding the RPM's too long in fifth gear when he shouldve shifted up. The Honda CBR300R rider also appears to be fully geared up, there is no indication whether the Ninja 300 rider is geared up. On the track though, the Honda CB300F should be able to out manuever the Ninja 300, like its older 250 sibling...

In the real world if a Honda CB300F came flying past a Ninja 300 in a crouched position running at top speed, the Ninja 300 would take miles to catch up and would probably give up before catching the Honda CB300F.

Honda CB300F Performance

No doubt Honda has reengineered the Honda CB300F to compete with its main competitor the Ninja 300 and in markets abroad there exist the Z250 which is essentially a Ninja 250 but naked. In comparisons between the old CBR 250 and Ninja 250 the difference between the two in absolute performance was so little it boiled down to rider preference. The new Honda CB300F, however is a pretty big upgrade although it may not seem like it by merely looking at the upgrade in displacement, with its lighter weight while retaining the same on track flickability of the CBR 250. The Honda CB300F is a contender not to be taken lightly with the extra torque and horsepower.

There are many ways to improve the performance of the Honda CB300F. From exhaust for the Honda CB300F, specially designed air filters that flow more air that utilize different filter designs from cotton gauze to foam and oiled paper. A fuel controller is also recommended to adjust fuel in accordance with higher intake airflow and higher exhaust velocities. But probably one of the best performance options for the Honda CB300F is to get better tires. Honda has chosen time and time again to use the IRC Road Winners, these tires are ok for slow riding, but they have a tendency to just let loose all of a sudden with no warning when they reach their limits.
