Whats the best performance mods you can do to the 250r?
Im looking to do some aftermarket mods to my stock 250r.
I read somewhere that yoshimura exhaust, with a power commander v fuel managment chip and a better air filter would gain more HP and Torque for the money and best results. Now i understand that maybe a personal opinion but what is hands down proven performance parts??

It really doesnt matter what you put on the bike as for performance mods, the bike is a single pumper thats almost right at the max of its HP, you can put an aftermarket exhaust and save a few pounds, you can purchase a set of Pirelli Diablo Rosso Corsa tires and ride it until there is no more thread left on the tire, but like a few have said and many will I am sure, get to know you and the bike what you can and cant do with it. Go take an advanced course in motorcycle training, watch the films mentioned above or read the books, get a few track days or get a lot of track days. After a year or 2 and many miles later upgrade to a bigger bike; if you still enjoy riding, and start all over again.

I guess what I am trying to say is its your bike do what you want with it, the mods that you mentioned for the bike would probably be the best, but learning to ride it to the fullest can beat any mods or after market parts you put on the bike. Learn counter steering, roll on the throttle, find the apex in corners, always look where you want to go in a turn. I have a friend that can out run me on a raider 150 in the twisties, not on the straights as I have more power, but he has many years of practice.

While you all have valid points, those are all in place, and of course i know you can always keep improving your riding. What i was asking was what performance parts are the best in terms of the numbers. Horsepower and torque. Increased throttle response and acceleration. All without shortening life of the motor or reliability. I do know that my 250r is running at its peak stock, but would like to increase this as far as i can go with bolt on parts. We all know that manufacturers have a range of legal limits to keep within to sell the bikes. But as an owner you can tweak and enhance this to your liking. Thats my goal. While selling the bike for bigger, this bike in its current form and settings i love, the feel and finish. Im sure after getting a use to her in the coming months i would like to increase the powerband a bit more. Now if i hit the limits of her performance and still want more i will consider a bigger bike. My first choice was a cbr600rr but opted for this because of price and a new over used/dogged bike!! But i feel this will be a bike to keep because of ease of use, gas milage, and fun factor. So if you please. Im asking for answers to that degree, thanks

Honestly, it's pointless.

You could add one of those 300cc kits. Bolt-ons just really aren't going to open anything up for you.

The other option is to buy a bigger bike.

You want to wring the absolute last bit of hp out of her?

Power Commander V from Jet Tuning $380
Full Exhaust $400-600
High Flow air filter $44-80
Professional Tune for the above. $300 ish (?)

And of course all the various weight saving mods.

All of the above, also a 13t front sprocket will help with acceleration .
At the end of the day it will still be a single cylinder 250cc bike that is designed for putting around on, it doesn't matter how much cash you throw at it. So here's some options for you, do the full exhaust, air filter, pcv & sprocket costing maybe $2000 depending on brands, shipping, fitting & tuning or put that money to one side & keep it for a head start on a bigger bike that will make you happy.

@250 Angel

Thats just it your not going to get any head snapping pull the front wheel off the ground 200 MPH out of this bike, its a great commuter/learning bike. It gets great fuel mileage, gives plenty of grins under your helmet. Unfortunately for us modders/customisers Honda did the bike right the first time.

Like grynchmeister pointed out you can spend over $1000 however you might only gain 2 - 3 more HP stock you have maybe 24HP so if you dont mind spending a lot for minimum HP gain then buy what your heart desires. Like I mentioned above your better off getting some GOOD tires, take an MSF course, and going to the track. Learn the bike and your capabilities on it, then when you go ride with your buddies and hit the twisties you can amaze your friends with how you can keep up with and even pass a 600cc bike in the turns.

I know you are wanting more HP Look at my avatar thats my 250 I have put everything on it that you can imagine, spent more money on it then I needed to and it still only does 155 KPH 96 MPH down hill with me and my wife on it. The bike has only been out a few years let the aftermarket guys catch up with the bike.

Ill say it again MSF course and track days will get you more out of the bike then any amount of aftermarket parts you can put on it <----- trust me on this. Not the answer you want but its the best answer there is.

I just don't get it. Every time a newcomer ask for tips on modifications there are a team of folks saying stuff like: it's only a 250, don't waste your money, buy a second hand SS bike and so on but the truth is MOST of us have made performance modifications on our bikes.
I don't like a heavy and bulky SS bike to go through heavy traffic, I just love to hang around on my little CBR and I just wanted a little more pick up for my weekend rides. Is that a sin??

Its your bike your money spend and install what ever you want. You NEWCOMERS are asking us OLDTIMERS whats the best way to get more out of the bike. I have already been there and done that. I have spent enough on my 250 to buy a new SS bike, and its still not an SS its a 250 and thats all it will ever be no matter how much cash you throw at it.

If your asking for someones opinion and dont get the answer you want to hear thats not our fault. Most of us have been there and done that with the 250 we know what you can get out of the bike in terms of HP. Its a great bike for learning and commuting on. MSF course and track days is money spent more wisely. Thats my opinion.

I think it really centers on the individuals expectations. I for one wanted a bike to learn on, and to commute with. I knew going in that I wasnt getting a "fast" bike. Right when it came time to purchase the Ninja 300 was released, so I hemmed and hawed some more. Ultimately I chose the Honda. Its light, fun, easy to learn (hard to master! lol), and, its a Honda!
Im not staying stock (obviously if you have read my jbp thread), but its more for the fact that I like to tinker with stuff than anything. The hand grips were too small and I felt more vibration than I cared for, so I added foam grip covers.
I dont really care for the stock exhaust note, and managed to find a used akrapovic for about half of what it retails for.
I used the difference to pick up the lowest cost dfc I could find.
From my experience with cars, piggy back units/tuning typically smooth out power delivery (mostly by way of adding fuel), while decreasing fuel economy. But at least on the 250, the mpg loss is negligible for me. 60-65 mpg is still well above my FR-S at 22-26 mpg. And the jbp did indeed smooth out the power delivery.

Above and beyond that, any mods will be just because. I will more than likely end up with a pcV & tune since I am not that far from Jetttuning. I realize its financial folly, but thats ok for me and my budget. I will do it for the tinkerer I am.

By far the best thing I did was the MSF basic rider course. And even though the sport bike course is mandatory for me (military), I am looking forward to it. When I can get more professional training, I will.

So I guess the real question is 250 Angel, what do you expect to get out of the bike by modifying it?

This happens on the car forums I'm a part of too, and for good reason.

Yes, you could throw money at a 250 and make a little bit of power, but honestly it's stupid. There are minimal (almost unnoticable) gains to be had without major changes to the engine, at which point the bike WILL get worse to ride on the street. It will still be slow, and it will be worse to ride. And you'll have a lot less money. Net loss.

There just isn't a little more pickup to be had.


And honestly, the days of the "easy gains" like an intake and exhaust are long gone. There's a lot of money behind making an engine run at it's peak right from the factory. There's nothing there to get.


Basically, by the time you made a 250 remotely fast you'd have spent enough to buy a 250 and a supersport. Then you get the best of both worlds, rather than a single awful bike.

It's because most of us have gone down this road, I've spent over $2000 on the bike since October , I've had a friend from Honda spend lots of hours to squeeze more out of it & to be honest it was a waste of money as my cbr250rr still flogs it.
If people want to ask questions & don't like the answers then don't ask, as for the 600rr it only weighs 25-30kg more than the 250 & less than the 500r.
At the end of the day spend your money how you want to but were just letting newcomers know it's a lot of cash for very little in performance.

All the replies in this thread have offered sound, honest answers to your questions: There is very little return on your money when it comes to bolt on parts and the quest for increased performance... now if you want an aftermarket exhaust because you like the way it looks, sounds, and will drop 13 to 15 lbs over the stock muffler... go for it. Most of us have replaced the muffler for those same reasons.



... We all know that manufacturers have a range of legal limits to keep within to sell the bikes...
That's not true... if it were true (at least in the U.S.) an 18 year old squidly noob would not be able to walk into a dealership, throw down for, and ride away on a liter bike (or a 600 Sport Bike for that matter).


... Im sure after getting a use to her in the coming months i would like to increase the powerband a bit more...
It's not an old school, two stroke Yamaha RZ350N... you're not going to be able to do anything to the power band of this bike. Unless you pull the motor and ship it off to HRC. That doesn't seem likely.


... But i feel this will be a bike to keep because of ease of use, gas milage, and fun factor. So if you please. Im asking for answers to that degree, thanks
1) Install a 13T front sprocket, SpeedoDRD, sticky tires, and the exhaust of your choice.

2) With out doing anything else to the bike, it is fully capable of providing startling amounts of sphincter pucker... go out and play.

3) Keep your expectations realistic. :)

Thanks guys for all the posts and comments. To the question from grynchmeister, I guess what i hope to Gain from modifying it was to get more of a grin factor by feeling more power out of a smaller bike. While a 600rr does this well for a slightly heavier bike. I guess ive always had an appeal or obsession with making little things go faster or perform better than stock. Kind of like that feel of achievement, or pride in knowing you did the impossible or could do more with less to prove everyone wrong. Like rooting for the underdog because no one else believes in him. So to say the least, the bike has already passed my expectations of how it would perform. I havent even given her all that shes got, being that shes new with 10 miles on her now. Just wanting to break her in easy til the 600 mile service. After that im sure i will really give her a run for the money. And yes i would like to drop the weight and look with the stock exhaust. Just would like to get the best while im doing it. As for the long term goal of the bike. Yes shes a commuter bike and a breeze to ride. But i never intended to use this bike to race or do wild tricks on. But if i could i would like to achieve making her one of the top bikes in the class of 250r. Kinda one of the elite. While i may stand with all others that have modded their bike to that max, that is a circle im willing to work toward. For all other that think that a 250s a 250 who cares, well i guess the numbers show. Anyone who loves theyre bike for what she is and enjoys the challenge of tricking a small bike for the pleasure of doing it. While no offense intended to the veterans of the sport or guys that have rode for years and look down on others cause of how big they go. Thats entirely up to the owners, it easy for anyone to say get a bigger bike, or thats a piece of ******************** bike. the real Enthusiasts enjoy the fun of making something theyre own and standing out not because of how powerful you are but because you do something others didnt care to or could do. Thats the honor in owning a bike that your proud of. Thats what i want!! To know i built a bike(so to speak) that i can call my own and stand by saying "Yep, thats my baby, no matter how little she be, i love her for what she is" isnt that what all bikers and car enthuseists are about. Feeling good about what you have, not what others say or can do to try to make yours inferior. I guess for me its not about having the biggest gun to blow people away, its having this little dinky gun that barely fits in the palm of your hand do the most damage than that big one did. Grins :) like will smith in men in black with the little gun. Classic!! So yes thats my intention. And hey if she only wrings out a few more lbs of torque and a few more #s on the HP. Then thats cool, as long as she looks good doin it and is fun as hell to ride im a happy man in heaven. To all the 250r owners out there. Keep the little beast alive. And may she live long and adventurous. Hope to see and hear of her doing things and being places noone ever thought could be possible. Thankyou all for your posts and happy modding and safe riding.

good attitude! between all the members on this forum, nearly everything has been done, or is currently in the works, to improve on this great bike. just take some time and use the search to find them. you will probably find there is more to be gained by weight savings than adding HP's. every 15 -16 lbs lost will roughly equate to 1 HP gained (aftermarket exhaust, fender eliminators, rear sets). there are areas to gain a few HP's (aftermarket exhaust, piggyback modules, overbore kits), some suspension mods that will make the bike handle way better (aftermarket springs, emulators, shocks, rear sets, clipons, sag adjustments and tires), lighting mods for visibility (HID projectors and LED kits) and gear. most of these topics have a DIY write up here on this forum and there are many here who can answer any question you could have regarding these areas. welcome to the forum.

If I really wanted to get some more fun out of the 250, I'd drill it out for safety wiring, mount up some sticky rubber, flush the coolant for Engine Ice, blow $1000 on one-piece leathers, and ride it to the track.

You get to ride it at 10/10ths pretty much out of the gate. Can't say that for the 600s.

You'll be lucky if you get 10% increase with all the mods mentioned. I know. I made 3/4 of them. Not for increased hp but for fun. I sacrificed power at the top end for increase on the bottom to midrange. 250 is still an awesome bike but it is still a single thumper that now sounds like a lawn mower.
