286cc single with a bore of 76mm and a 63mm stroke. The engine in CBR300R has definitely been lifted from the 250 and bored, CBR250R had the same bore and a 55mm stroke..

The procedure has graced the CBR300R with 30.4 ponies and 19.9 ft-lbs of twist, coming on strong between 7K and 9K rpm. Weight has been scaled at 362 pounds which is lighter than the CBR250R by 4 pounds, however that is without the optional ABS.

CBR300R does fall short of the Ninjette 300's 296cc displacement and 39 hp/20 ft-lbs but the Ninja is a whole 21 pounds heavier so that should even things out fairly. No word on if it will be jumping the pond but Honda America never even got around to announcing the 250 so its more likely were going to go straight to 300...

Not true.

Curb weight for the CBR250R is 357 lbs. The CBR250RA (ABS) curb weight is 366 lbs.

So, the non-ABS 300R is actually 5 pounds heavier than the CBR250R.

780 = seat height in mm
164 = weight in kg
286 = CC
76x63 = bore and stroke of the engine
22.7 = KW which is just over 30HP
110 = front tire size
140 = rear tire size

I guess nothing in the leaked document mentions pricing? Does anyone know approximately when we can expect more specifications and information to release?

That isn't a "leaked" document... it was posted in plain view at the China motorcycle show.

For those in the U.S., it's when American Honda Motor Co. decides to make their official announcement, releasing the MSRP and other info about the bike. I'd say expect AHM to make an announcement sometime around the end of the year, perhaps sooner.

Your best bet is to go the Honda Powersports website and sign up for their e-mail notifications... you'll then be among the first to know.

The CBR 300 R is a bigger CBR 250 R. The length of the CBR 300 R is 2035 mm, width is 720mm and height is 1120mm. When we compare it to the CBR 250 R, the length is increased by 3 mm, width is same and height decreased by 7mm. Honda has made the CBR 300 R lighter than the CBR 250 R. Honda CBR 300 R weights 164 Kgm which is 6 kgm lighter than the CBR 250 R. Honda has increased the wheelbase of CBR 300 by 13mm. The wheelbase of CBR 300 R is 1380mm. The ground clearance of both CBR 300 R and CBR 250 R is the same which is 145mm. Honda has given same wheels for the CBR 300 R from the CBR 250 R. 110/70-17M/C for the front and 140/70-17M/C at the rear.
Now the big part of the story which is the engine. The Honda CBR 300 R is powered by a 286 cc DOHC 4 valve single cylinder fuel injected engine which makes 30.4 BHP of power at 8500 RPM and torque of 27 NM at 7250 RPM. From CBR 250 R, Honda has increased the power by 5.4 BHP and torque by 4 NM. This engine is mated to 6 speed gear transmission. Honda has given disc brakes at front and rear. Honda is giving the ABS as an option.
In design Honda has completely changed the front of the CBR 300 R. The front headlamps and visor design is inspired from higher CBR models. Compared to CBR 250 R this is far more aggressive and edgy. The rest of the panels have given a minor tweak. The instrument cluster and the handlebar are also same from the CBR 250 R. Overall, the CBR 300 R is a tweaked version of the CBR 250 R. We can expect the Honda CBR 300 R next year in India.

Hate to burst your bubble, but the 300R is not "bigger" than the 250R... as far as Overall Length, Width, and Height specs between the two bikes, only the height is different, length and width are identical. The 250R is actually 5mm taller (this is per the 250R O/M & S/M specs) than the 300R, likely due to the mirror placement on the redesigned upper cowl of the 300r. Honda lists the wheelbase on the 300R as 10mm longer than the 250R, but in reality that measurement can and will vary depending on how tight or loose the drive chain tension is set.

The bottom line is that the rolling chassis of the two bikes are identical in every way. Ergonomics are the same. Which translates to the handling of the two bikes being the same. Which is a good thing, as the CBR250R is counted among the very best handling motorcycles on the market today.

However, one thing that remains to be seen is whether the Indian built CBR300R will achieve the same build quality as the bikes built in Thailand. Honda India needs to step up their game... it's no secret that the Thai manufactured CBR250R's were built to a higher overall quality level compared to that of the Indian CBR250R's, with better brakes, higher quality welding on the frames, etc.

This is why i've always been loving the stuff coming out of thailand...QUALITY bikes. The Grom's are built their and no one is having complaints about them

I would trust the ones built in Thailand also. They have been building bikes there for a while now. My friend that live abroad has a couple bikes over ther and mentioned that the quality is pretty high. Not sure if its because the main source of transportation is by motorcycles.

The Grom guys are LOVING their groms, I have yet to hear about an issue with them, and they're built in Thailand. IMO, Japan first, Thailand second....when it comes to build quality.

Honda keeps the quality control up there so its not a huge issue. Would be nice if the motorcycles were made stateside but thats only going to raise the price.
