i honestly reckon you're gunna need a bike with more torque than the cbr300r.

Stunting
So, after 10 years of riding I finally want to start stunting. The CBR300r has been a loyal companion for the past year, but it seems very incapable of doing any type of major stunts at decent speeds. EX: I can only pop a wheelie (not power style) in first gear. Second gear seems somewhat impossible but I have only been trying for 2 days. I can, however, constantly pop one in first gear. The issue here is that I sit at around 9000rpm until I reach break point. At break point I can keep the RPM's reasonable but the bike is going at a top speed of 10mph....
Not sure if anybody else here is stunting, but I figured I would try.

I am aware that I need a bike with more torque for "easy" wheelies, that said, thats not the question. I know some people stunt 250's with less torque. If this is the case what things are they doing to get the bike up past first gear? At some point I would like to try and do it in third so I could be going 40mph or so. Anything past that would be rather stupid and I think near impossible.
I have watched the video of myself doing it to understand the bike and how it works. At 7500+ rpm the bike picks up fairly well and just needs a bit more to get to balance point. When I land the wheelie I am roughly going 20mph. I have read that some people shift while in the wheelie to get to 2nd... if this is the case I could try that once I am more comfortable. I have attempted to use the same technique as first gear but it doesnt seem to be working for 2nd. That said, I am normally at a 20mph start when in second gear. I could attempt to go from 13 or 14mph and rev the handle to 9000rpm and drop the clutch, this might pick the bike up in second. Thoughts are welcome, as long as they are not "get another bike" cause thats not what I want to do, otherwise I wouldt be posting this here.

you could try dropping number of teeth on the rear sprocket...14 teeth is stock.
Hm... I had heard that some gear modifications could fix this. I wanted to try it stock, but I might have to move to that direction. I also thought about adjusting the clutch so that it would slip faster... but honestly if I can grab the bar in enough time I dont see the real perk doing that. I will check out the teeth option. Thanks
So, after a bit more playing, I feel it is 100% impossible without messing with gears/torque to do in second gear. From first gear I cant even do it when the bike is rolling past 15mph. I can get it up everytime as long as the bike is in 1st gear at 5000rpm w/ burst to 9k. Drop the clutch at around 9k and bike comes up nice and smooth.
In case you guys are wondering, the reason I want to avoid doing this in 1st gear is the bike is very unstable. If you pop a wheelie and you are at the wrong angle you dont have speed to keep you moving forward, and in some cases can land sideways. I have noticed this several times and have to ensure the bike is perfectly straight and coasting at around 5 - 10mph.

1:1 ratio ;-)you could try dropping number of teeth on the rear sprocket...14 teeth is stock.
what do you mean 1:1 ratio? im not familiar with the concept just yet. Never had to modify the gears to get it to do anything.1:1 ratio ;-)
maryk...
If you wish to stunt that 's cool....myself I think this would be way more fun....just saying..

Honestly this is one of my favorite 300 R video's. The music/the way the video is presented to me is awesome.

That is just racing... I have already gone to track days. I want to learn a skill i dont know

should have read
you could try dropping number of teeth on the front sprocket...14 teeth is stock.
for you, going to 13 or even 12 teeth on the front sprocket will give you a lot better acceleration and make up for the lack of torque you need to mono in 2nd.
very cheap mod too
1:1 ratio means that your front sprocket (under the cover) AND the rear sprocket each have the same number of teeth. So the front sprocket had 14 teeth then for a 1:1 ratio the rear sprocket would have 14 teeth.what do you mean 1:1 ratio? im not familiar with the concept just yet.

Yup Treve82.....

I screwed it up you are correct. Above /\ is what I meant to say..

all good, just taking the piss mate . . . . don't worry i expect it to come back in spades haha
No worries.. I'm an easy going person..
People who are stunting these bikes (including the CBR250R) are using sprockets to get a much lower final drive ratio... 13T up front*, and a rear sprocket of at least 42 to 45 teeth (or more).
* A 12T sprocket is just too small of a diameter for the chain to efficiently rotate around.
* A 12T sprocket is just too small of a diameter for the chain to efficiently rotate around.
With these modifications, will it effect how I drive normally? I assume it increases low end torque, but does it **** with the overall ride?>
well with mods as Mike mentioned ...you gas mileage will drop some..because the engine is revving higher at any speed. Acceleration will be quicker with lower maximum all out top speed.
Would it be less than 80 or 70? Right now I normally go around 60 - 70mph depending on the day. A quicker start would be nicer, but if i lose 20mph from topspeed I dont know.
if you go to the gear ratio mentioned (13:43 ish) then i'd suggest also buying a 15t fron sprocket for daily use and swapping to the 13t for fun. only an hour job to change front sprocket, you'll get very quick at it.
