Honda CBR300R: Acceleration and Top Speed

Honda CBR300R Acceleration and Top Speed


If you are looking for Honda CBR300R Acceleration and Top Speed. Then here you can find all the details.

Honda CBR300R 0-60 mph in 6.36 Seconds

The Honda CBR300R is an entry-level sport bike that serves as the direct successor to the CBR250R, a model that was produced from 2011 to 2013. 

The CBR250R and Ninja 250R were direct rivals, and both enjoyed strong sales and widespread popularity. In recent years, there has been an increase in the engine size and power of entry level, lower CC motorcycles.

 This trend started when Kawasaki introduced the Ninja 300 to the market in 2012, replacing the Ninja 250R.

It's highly likely that Honda increased the single cylinder engine of the CBR250R from 249 to 286 cc by adding a longer stroke in response to Kawasaki's Ninja 300 and in anticipation of other rivals possibly releasing larger engine models.

The CBR300R once more took second place to the Kawasaki Ninja 300, much like the CBR250R and its single-cylinder engine did when compared to the Ninja 250R.

Both engines were roughly the same size, but the Ninja 300 had an extra cylinder, which allowed it to rev higher than the CBR300R and it did, which resulted in more power being produced—35 claimed horsepower as opposed to 30 for the CBR300R.

Those who preferred commuting in comfort and with a little less frantic engine due to the typically torquey single cylinder engine character tended to favour Honda's CBR300R more.

Although it is arguably less thrilling than other options in its class, it was thought to be the more sensible choice and had better "Honda" build quality.

CBR300R Dyno – Power and Torque

The Honda CBR300R generates 27 horsepower at 8500 revolutions per minute, or about 3 horsepower less than the stated crank output.

Given that you typically lose between 10 and 12 percent of your power during transmission, that is about right.

The power and torque curve is almost identical to that of the CBR250R, with the addition of 36 cc expected to result in a slightly higher peak and more power and torque throughout the entire rev range.

The CBR300R's delivery is typical of a single-cylinder engine, which rapidly increases its power and torque with a typically significant drop-off after reaching peak power, in this case at around 8500 rpm.

While the CBR300R's 10500 rpm maximum is not particularly high for a motorcycle with a small capacity, it is quite high for an engine with only one cylinder.

The engine shares some characteristics with its smaller CBR250R sibling, but it is undoubtedly not a screamer and does not react as well when pushed to its rev limiter as some of its competitors.

The engine is most comfortable for optimum acceleration in its mid and upper midrange, which is between 6000 and 8500 rpm, but is still manageable from 3000 rpm around town.

The CBR300R appears to be a very poor alternative to KTM's single cylinder model, despite having a larger capacity.

Speed       Time
0-10 mph 0.64
0-20 mph 1.37
0-30 mph 2.00
0-40 mph 3.07
0-50 mph 4.58
0-60 mph 6.39
0-70 mph 8.90
0-80 mph 12.41
0-90 mph 18.07
SS/QM         15.14/85.8 mph
SS/KM         29.608/96 mph
SS/Mile         43.46/97.3mph
Top Speed 97.85 mph

The CBR300R is one of the slower motorcycles in the 300 cc class because it lacks the higher peak horsepower at higher rpm of competitors like the Ninja 300 or Yamaha YZF-R3.

The CBR300R's performance is more comparable to the Ninja 250R's, though it does have a slight advantage under pressure and more power in the low and midrange.

Even so, the CBR300R has respectable performance as evidenced by its impressively quick 0-100 km/h time of 6.77 seconds and respectable 0-60 mph time of just 6.36 seconds. 

In order to achieve the best results, you must briefly release the clutch at about 6500 rpm, then shift into first gear and accelerate to the redline before hooking second.

The CBR300R accelerates from 0 to 70 mph on a highway in 8.82 seconds and completes the quarter mile at 85 mph in 15.14 seconds, which is respectable.

Like all smaller capacity motorcycles under 50 hp, the CBR300R's top speed is highly dependent on your size and how favourable or unfavourable the wind is.

In neutral conditions, you can anticipate to see 97.85 mph, which is just shy of the magic "tonne" speed. On a good day, however, you might be able to reach a genuine 100 mph, which is definitely possible on a decline or with a tailwind.

Speaking of highways, if you reside in a nation where cars consistently exceed the posted speed limit, and you do as well, it leaves little room for acceleration for overtaking. There is enough speed between 70 and 80 odd mph to pass slowly moving traffic, but for the best results, you should shift down to fifth.

Only top gear and a rapidly declining power curve are left for the CBR300R to overtake other vehicles on many European highways where traffic can frequently sit at 80 mph or faster.

There is sufficient engine performance to keep up with traffic and offer nice but constrained thrills if you do not exceed 80 mph.

Final Word

If I had to keep the CBR300R for a while, I would think about getting an exhaust, an air filter, and having it tuned because its CBR250R little sister responds well to bolt-on modifications.

If you must have a Honda entry-level model other than the 300, the CBR500R might be a better alternative.

 It shares a lot of similarities with the CBR300R in terms of platform but has an additional cylinder and more power and acceleration.
