Hi all,new member here.
I just picked up my brand new cb300f in red last Friday, love the bike so far apart from a little lacking in power, but that is because I'm used to motorcross bikes I guess. I'm new to riding street but have been on dirt bikes for 20 plus years and still love it. I'm from brisbane, Australia

Congrats...I have had my CB300F for about 3 weeks now and after 250 miles on the odometer it does behave differently - I have better throttle response and it just feels more powerful than when I first picked it up from the dealer. May be it is a result of being broken in or more of me getting used to it :confused:

Thanks guys. I'm most defiantly getting a full exhaust as the bike is so quite it's crazy. But also wondering is there retunes or flash tunes available to try and squeeze a little more power out of her maybe paired with a aftermarket filter like a k&n that's is if the stock filter is very restrictive? . Any advice in that department.?

G'day mate,

I put a K & N filter in mine plus a Delkevic slip on muffler for better performance, sound and less weight (sheds 4kg).

You get the Delkevics off ebay, the seller lives just south of Brisbane actually.

Another good weight shedding trick to improve the power to weight ratio is to take out the lead acid battery and put in a Shorai lithium ion instead. 2kg lighter.
Ive knocked over 10 kg off my bike by doing this and fitting aluminium bars and a tail tidy etc etc.

Anyways, enjoy the bike.

Thanks for the tips mate. I looked on eBay for the Delkevics I can't find it any chance u can send a link also how much was it?
Also looked on the net for k&n for the cb300f with no luck were did you get urs from and for what price?
The tidy tails do look sweet

Sorry bout slow reply, forgot to subscribe to this thread.

I'm **** on computers but i think if you copy and paste this into your URL it should bring up the delkevic. $319 AUD, free postage within Oz. You will see its for a CBR250, You just have to cut 100mm off the end of your header pipe and it fits on sweet as. They do a tri-oval one as well which looks pretty cool.

You get the K&N filters direct from K & N in the states as they have free postage world wide (good on them eh!) works out cheapest. $82.84USD They didnt change the air filter box on the 300, slots straight in.

Heres the link for the 250 tail tidy, see my earlier thread on fitting one to a 300, its not that tricky.

Hope this helps.

Mike: I did pipe and filter as one so cant offer opinion on performance advantage of just doing filter if thats what you were after? I haven't had any running issues at all, the fuel management system seems to compensate perfectly for the lesser back pressure of the freer flowing pipe and filter. I'm sure you would see further gains with a power commander as well, but my budget doesn't extend that far!

Bike handles very well is light and nimble. Very easy to ride.
Depending on wether you have had fast bikes before you may be disapointed by lack of power.
The bike I find at speeds of around 90km/h and over or on very windy days feels very unstable at times due to no windshield.
Over all tho great little bike and I say little as it is rather small but fits me like a glove as I'm only rather short at 165 cms tall.
Oh and the thing that I like the best it looks great I love naked sports bike and this is the best small cc naked sports bike by far

Ordered my k&n air filter and also my youshimura r77 exhaust in carbon they are both coming from over seas so it's gonna be a long wait. In the mean time I'm thinking about replacing the clutch and brake lever as I think they are very cheap looking.

yeah they look like they plucked them outta the spare parts bin eh!
I painted the ones on my 250 black which helped, but I'm keen to get something with more of a dog leg in it like my XR ones.
As you've probably noticed there's a whole raft of expensive fully adjustables out there.

I no right they are shocking.
Looking on eBay they is a large range on good looking levers from between 50 and 120, even some as low as 35 that look much better then the standard ones. I'm thinking ether red or black and probs change the bar ends to red also . And the eBay ones are all adjustable to . As for quality or function I'll just have to give a pair a try and hope for the best..

At least if this was an area they intended to cut back on that it was this and not something else more vital to our bikes.

Keep us posted on what pair you end up getting.

I got a pair of cheap ones from ebay
They are slightly shorter at 14.6cm long
I try'ed uploading a photo don't think it worked tho I'm on my iphone and I can't find anything to add attachments
Anyway they were only 26 bucks delivered and look like they will be decent. But at that price it dosnt worry me if they are crap I'll try another pair. Ether way they will look better then the stock ones.

When u put on the [email protected] and exhaust did your computer have any trouble calibrating the new air/fuel ratio and supplying more fuel or is the bike
Running lean?
Are you getting any backfiring?
Or the bike running seeming to run extra hot?
Just trying to figure out if I should wait till I get a power commander or Jucie box and custom tune before installing [email protected] if it's gonna lean the motor right out

Absolutely no issues at all, the sensors in the fuel management system seem to detect the changes and the ECU compensates. I'm skeptical of some of the posts Ive seen about re-setting the ECU (by a variety of methods!) as it dosent appear to be necessary. But hey, I'm an engineer, not an engine tuner!
I can only speak from my experiences of fitting a Leo Vince Slip on muffler + K&N to a CBR250 and a Delkevic slip on + K&N to my 300. I just started up and rode away with no detectable issues.
Just go for it!
