DYNO TEST: Honda CB300F With Yoshimura R-77 Exhaust On the Dyno (SOUND CLIP) | MC GARAGE

Whether it’s your first bike or your new track bike, replacing the factory exhaust on your Honda CB300F will be high on your list of things to do to trim a substantial amount of weight as well as improve the sound and appearance of an already good-looking motorcycle. The new Yoshimura system for the CB300F reduces weight by almost 10 pounds. Shedding weight, of course, equates to better performance but the dyno shows that the R77 system also increases power across the rev range, which makes this a very good investment for anyone looking for a performance improvement. Watch the video and see for yourself.

That yoshi exhaust sounds amazing, love it.

This bike sounds real nice even stock

honestly tho I dont understand why it isnt street legal. The power gain is very subtle

[@bangyahead1]

Very cool!! I have to wonder how this exhaust system would effect a Yamaha YZF-R3 and what performance gains there would be. Similar results I suppose, but it would be nice to know exactly.

[@motomunky2731]

Wouldn't you need to do a ECU flash or Power Commander to get the full benefits of a full exhaust?

[@DearMajesty]

wondering the same. i wonder how much more power it'd make with a tune or ECU flash

[@joedoole3527]

On engines this small fuel tuning isn't necessary, but will indeed yield slightly more gains. We've tuned stock 300's, 250s and even stock Grom/Z125s and seen 1-3 HP increase across the rev range over the stock tune. Add a free flowing exhaust and air filter setup to this and you can easily see 3-5 HP gain over a stock bike. This doesn't sound like much but when your talking about an engine that makes less than 30 HP anyway that 3-5HP equates to gains of 10% or more, which in realistic terms IS a big gain from a simple mod. Add to that the fact that these bikes only weigh a few hundred pounds and you really can feel a 3-5 HP difference.

[@prayanjaltomar752]

@@joedoole3527 i have cbr250 ,if i remove its exhaust completely without reflashing ecu or any other tuning will it harm the engine ?

[@Pinprix]

Ari, I remember you guys fielded a 250 on the track against a bunch of kawi 300's in one of your video's and you seemed to be faster everywhere but the straights. It seems you guys like to be the underdogs, but why go with the lesser powered Honda 300 versus the Kawi? I imagine you are going to race this bike also.... Are you guys just Honda fans, or is there something about the Honda that you like better then the Ninja. Just curious!

[@julienfoss1392]

they were ninja 250 yo

[@GT6SuzukaTimeTrials]

2:02 horsepower gain of 1.40 and torque gain of 0.38

[@katana258]

+GT6SuzukaTimeTrials 1.5 hp worth all that $$$$$ .. NOT .....christ you want more power buy a fz 07 / 09 ...really anything else...you buy that bike to put put around , get good milage ,and easy ride , with honda build ...fit and finish and enjoy the ride

[@GT6SuzukaTimeTrials]

Roy Rodriguez I agree. FZ-07 is pretty much the best street bike ever made.

[@katana258]

+GT6SuzukaTimeTrials heck if you want more power just about anything is better then this ... but it is a nice bike in its own rights

[@MJT-DA]

+GT6SuzukaTimeTrials Hey! What about the r3 LOL?!

[@GT6SuzukaTimeTrials]

R3 is good but I prefer Honda.

[@MB3Drift]

You don't say that the torque was way too low compare to the stock exhaust. On this kind of bike, torque is the thing that make pilots happy, not a poor alone horsepower

[@SickMy_Duck]

The torque was increased wasn’t it?

[@athaothao2880]

nice dyno tuned tuning honda cb300f yoshimura r-77 exhausts

[@Frejborg]

Yeah would have been good to know if the ecu and tune were there to make gains, or if they would increase the gains. Also the torque increase would have been nice not just he HP. I'm considering getting a full system on my 300.. or at least a slip on.

[@sterlingroberts6240]

They literally showed you the overlapped dyno charts. Torque is what a dyno measures. Hp is then calculated from that. This is literally everything you could want, but instead you want the peak increase in torque?

[@Cramec]

thanks for that one

[@Siper2]

Since you guys are doing a lot of new rider videos, how about a comprehensive list of hand signals for street and off-road riders? That would help folks out! :)

[@pritamghosh4643]

Make a slip on vs stock comparison.

[@DearMajesty]

I just picked up one of these fire-breathing beasts! If you a chance to respond Ari, what oil did you use in this bike? I have some worries about using the suspiciously thin 10W30 oil, which is the only one that Honda recommends.

[@benl7070]

I know im not the reply u wanted but id say use 10/40 semi synthetic

[@TheZom1965]

Cool. Thanks.

[@chernorizetzhrabar1313]

How much $$$ for Yoshimura just for an extra 1.5 hp?

[@silentxsails4098]

What would you say the top speed of the cb300f is with the r77 installed. Also is there a map of what states allow race exhaust. I see yoshimura and other aftermarket exhaust in my city all of the time.

[@throttlelock2354]

can the Yoshimura go on the cb300r?

[@entitykeeper8869]

You should've dynoed with the baffle in. Most smaller cc bikes make better horsepower with back pressure.

[@JediRhymeTrix]

+Sean Wallace Race exhaust systems don't come with baffles.

[@ProDigit80]

+Vedant Vohra (VDizzL3) It has to have back pressure if you want it to be street legal. Without back pressure, a fuel controller will correct the A/F ratios.

[@entitykeeper8869]

All my Yosh pipes had removable db killers.

[@joshcowley586]

Spend 300 dollars for 1 horsepower. Makes sense.

[@manuelfriend4060]

Wait this isn't street legal? why? It's barely any louder.

[@trucker2b]

no air filter

[@GT6SuzukaTimeTrials]

This bike is too small for me. I'm 6'0 210 lbs with a 34" inseam. I'm thinking of starting on either a Yamaha WR250R or the FZ-07. I considered a CB500F but for just another $1,000 the FZ-07 destroys it in every area, and the CB650F is way too expensive while also not being better overall than the FZ...

[@julienfoss1392]

you could still ride this bike pretty easily im 6" 4 and 220lbs with a 36" inseam and I can fit on basically any bike
