Exhaust Upgrade

[Dazalenco]

Hi,

I own a 2020 crf250f.

Very new to the dirt bike scene

want some help for some upgrades. especially exhaust,

Any help is appreciated

Sorry, but this sounds ridiculous to me.  If you're new do the dirt bike scene why would you think your exhaust system is holding you back?  In general Yosh makes great systems for Honda, but so does Honda.  In general, to go faster on a dirt bike the necessary tools are seat time, tires, suspension, brakes, and then maybe exhaust.

100% agree

Save your money for buying safety gear, a spare air filter and oil changes.

 

The stock exhaust is not holding you or that bike back,

once your riding skills allow you to push it to it's limits, it's probably time to upgrade to a more performance oriented bike rather than mod it.

Even before modding the engine, you'll soon reach the suspension's limitations if pushing that bike too hard.

You got some solid advice from our members, I hope that you listen to them and save your money rather than make noise that just irritates your neighbors.

Hey, check this site out.  TONS of stuff about your bike and some info on what you could do with your stock exhaust if you decide to keep it for a while longer (not sure if there is anything there on aftermarket exhausts?).  Either way its worth checking out.  Good luck and congrats on the new bike.

Also, I agree that the exhaust probably isn't holding him back performance-wise.  He never said it was.  But if the guy wants to buy a shiny new pipe for his bike what's the big deal?  Sometimes we just want some bling for our bikes.  We cant all be supercross champs and master mechanics.

Straight up 100%....

Stock exhaust systems on anything other than a genuine competition machine like an MX bike ... Are beyond boring and lame... And not everyone is into boring and lame.... 

[mixxer]

Pro-Circuit... Excellent exhaust systems....

If they made one for the 250, that's the one....

Learn how to ride your bike. Once you have mastered your Honda you can purchase a real dirt bike. Your CRF is a toy. Putting performance parts on your bike will not make you a better rider. Most entry level riders believe aftermarket racer parts make their bike better and as a result make them a better rider. Not so. 

Too many riders waste money and ruin their motorcycles and make aftermarket parts suppliers rich by subscribing to this foolishness. Save your money for important stuff like riding and safety gear and gas for your bike so you can get out and ride it more and become a better rider. 

Once your riding skills develop beyond the ability of your entry level bike you can trade or sell your unmolested un modified Honda and move forward to the purchase of a real dirt bike that suits your ability. 

Trying to modify your CRF to the level of a proper dirt bike is possible, but would cost more to equip and develop than the cost of a real dirt bike and would likely be overstressed beyond its limitations and perhaps have reliability problems. 

Why not enjoy your play bike until you reach the next level instead of trying to rework it into something it's really incapable of.  Just my experience for you to consider. Best of luck to you

Awwwwww Man....

C'mon Everlast.....

Personal stats for me:

Age = 59¾...

Years riding = 46....

Bikes owned= Dozens upon Dozens

Number with OEM exhaust = ZERO

Your advice is solid.... But my God man, a man can only go so low...lol... 

A nice exhaust system is one of the biggest joys one can purchase for his beloved machine... If not THE biggest... 

I could (maybe) see going stock when it's a system that comes on a 450f bike... Or a KTM 2 stroke ... Because they are real Performance systems... (even then, nope) But a "muffler" ?!?! ... Gross!! 

I know they can and do have some design to them... And they are better than a potato stuffed in a pipe...

But it would kill at least half my joy... If not damn near all of it... To run a muffler instead of a performance exhaust system....

I'm also not a fan of excessive noise... Everybody knows that... Growl, not Bark is my sound preference...  Turbo muffler style in hot rod terms...

But good lord man... Stock exhaust when it's a muffler?? No thanks ??

I kinda agree with learning to ride stock and kinda not after hearing everyones explanation. IMO if it was me I would ride the bike stock for about 10 hours or so get the feel of the bike and see what I like and what I dislike about the bike. In some cases you might not even like how the bike handles which was a problem with me as I had a kx250f 2019. I rode it a couple of times and something about the geometry of the bike wasnt giving me confidence so I was able to sell the bike and get something else. So ya experimenting is the key

[GavMac78]

Please correct me if I'm wrong.  I'm running a carb on the 230F.  You can uncork the stock, add an exhaust/muffler or a full exhaust, and it will make little to no difference to the bike.  To get added benefits from the exhaust, you will also want to open/uncork the airbox, via snorkel removal and high flow airfilter.  However, when you increase the inflow and outflow of the bike, you need more fuel.  So for the 230 this means bigger main and pilot jets.  The 250F is Fuel Injected.  So to get the most benefit out of an exhaust and opening the airbox.  You will need an FI programmer.  Otherwise you will be running the bike way too lean, which can cause damage to the engine.  Last I knew, there was only one programmer on the market that was $225.

Most people put exhaust on their bike to make is sound meaner ?

On the 250f stock engine last worry is stock muffler. Get that suspension fixed before it hurts you

Ha. Good old mixxer. You youngsters are full of piss and sass. 59 1/2. Shit! I got aches what's older n you. In all seriousness this is a good thread for all of us to learn together. I have ridden several CRFs as described here and offered my advice as a general guideline for some, but not all riders. Without my experience and resume it may not carry much weight here in forum but suffice it to say I have a bit of experience to share. One experience is a recent one with a young man freshly graduated from college and starting a career and purchased a new DRZ400 and helmet, accessories and riding gear and started his journey into off road riding. $6600 for bike and $2200 for accessories and stuff and he is having a great time. Bike is financed and accessories are on Visa card. I enjoy sharing my motorcycle passion with everyone and when this nice young fellow asked for assistance/mentorship, i gladly brought him along on trail rides and got his dirt bike addiction started. Things were great for him....until he started reading forum posts like some posted here and started believing his bike was crap without an exhaust and all the other go fast goodies that some foolish forum fodder would claim. Fast forward to the poor kid disassembles his bike in his unheated small apartment garage stuck between his parked car and has another $1800 worth of go fast parts for his new bike and has no idea how to install them. The kid could barely remove air filter from a DRZ and had a big bore kit on garage floor in a puddle of coolant. After a few months of struggle he asked for help assembling his bike. Several visits later I was able to help him reassemble his bike and get it running. The irony of this story is twofold. First off he continues to ride his modified DRZ as before. He is a novice and seldom rides above 2nd gear at more than 15 mph. But quick study of his expenses(I do not charge for my help) and his cost for his loud pig of a DRZ would have purchased a KTM or Beta or other quality off road motorcycle. Instead my young friend has probably voided his warranty and is no better a rider than previously but now proudly displays stickers and decals and loud exhaust. The purpose of my suggestion is to caution new riders to study the information and results of these suggestions posted here as the modifications suggested may be a huge waste of money and effort. Just ask the DRZ rider that spent KTM money on a Suzuki and still can't run with the KTM riders. Just some advice to consider

Spot on on all counts.... No argument for that logic....

 

Problem is that new riders don't even know enough to know what they want... Or what change would make anything better for them...even tire choice is so far out of their wheelhouse ...

 

Now see if he had just wanted a nice exhaust system alone.........

Ha. That will happen when you dont hide my soapbox on me. I climb up there and start a friggin sermon?

I'm always happy to hear different points of view but never afraid to share my own views with a passion. Thanks to all for listening.

It will feel as if it’s got way more HP when it’s so noisy, it pisses every one off around you, it won’t make any more power of course, but the bike “will be”a little bit lighter at least. Especially if you carry your wallet when riding...?

You old curmudgeon you....!!

It's like listening to your favorite rock band out of your phone speaker.... You can hear it, sure, but it sucks... Which is fine if you are into suck... hahaha

Monotonous droning electric soulless bikes will be here soon enough...  

Gotta tell you though....

Honda provided a kick ass HRC power up kit for the 06 and up TRX450R ....  Bigger headpipe and different end for the stainless exhaust cannister (not a muffler

Honda said the exhaust was the same design format as their superbikes and the big headpipe and end cap from HRC would be able to make big power....

The kit was actually excellent....

And to its credit the pipe did make the same peak power as any pure performance straight through exhaust....

But it was notably down about 10% through the, to me, all important mid-range.... 

Same peak... Great stealth system.... But soft soft soft in the mid-range and peak torque areas....

The same is true for all non straight through systems compared to straight through on all my testing...

Assuming everything is tuned right for both systems.... You lose midrange no matter how well designed the silencing section is...
