Questions regarding modifying performance

7904 Views 19 Replies 11 Participants Last post by  Spacep0d
Hello guys, I'm a new owner of a red yamaha r3. Ive had the bike for about three weeks now and have managed to put on 800 miles. Did all the services myself so far (saved about 300 bucks DIY), and now looking to see what the real potential of this bike is. If you installed a new exhaust, performance air filter, and get a power commander chip, how much horsepower could you get out of this puppy? Btw I'm 6ft5 170 lbs and this bike fits me fine!! >:D

Honestly man you should just enjoy the bike for what it is. Super light, super nimble and extremely easy to ride and just enjoy. Spend too much money on mods for minimal HP gains and you might as well have just bought a 650, 600 or other in the next higher cc class. If I were to spend some money on performance parts, I would def do suspension first.

I don't know if I want to spend $9-1100 on an exhaust, PCV and filter for a measly 3-6 HP gain.
What do you do with the bike Joe* Planning on racing or using it as a commuter/fun toy? You would probably spend less on sprockets and chain which would improve acceleration with the reduction of top speed but koji is right. The bike definitely needs suspension upgrades along with tires to see some of that "true potential" IMO.
Throw some radials on,
do a track day with full coaching,
Learn that the potential is 100% up to the nut behind the bars.

Ditto on that
Part of the bike that's weakest is the rider, may not always be the case(if something breaks etc), but most likely you are
get yourself comfy to stay on the bike. Seat/clip on so you are at your best even riding in for a while

My disability insurance from my profession prohibits me doing motor vehicle racing I'm still thinking of a way to go to track or learn more from professional drivers to get coaching on my skills.....
To quote Pirelli, "power is nothing without control". Control being a combination of operator skill (training - you're not remotely as good as you think you are) and suspension. The R3 isn't one of those bikes that has massive fueling issues as delivered.
What amazes me on this forum is the folk that have spent a fortune saying they want more power, or a new shock, or brakes
and they still run the STD Wheelbarrow tyres which tie themselves in knots long before any other limitations.






I question how hard they are really pushing to justify the expense.

While I agree that the stock tires aren't so great, and that I wouldn't try to get too much power out of this bike, I for one would spend more money for better brakes. I so far have bought SS lines which absolutely helped get rid of the spongey feel. I bought some eBay levers, more so for looks but they actually helped since I was able to put them on the furthest setting. For me whether you push the bikes to its limits or not, good braking matters a lot.

I also think whether you push the bike to its limits or not, good suspension is money well spent. Even if you don't race or track, a good suspension greatly improves the quality of your ride.

A track day IS NOT a race day. It's practice for learning how to ride safer (whether for on the track OR street!).

I guess I'll weigh-in here on the mods thing. While I have the Ninja 300, I also am a fan of the R3 and just got to test it. With my Ninja, I really wanted to see what a lightweight sportbike could be with respect to mods, but I think mods for these tiny bikes are kinda all-in or not. I went the full-bore route, in-part to show all of this on YouTube and also to see if I could make a fun sportbike that much more fun. So, I have the full-exhaust, custom tune, quickshifter, shorty levers, Woodcraft clip-ons (The N300 really needed them), EBC HH brake pads, double bubble windscreen and a bunch of other mods. I also have Pirelli Diablo Rosso II tires, 15/43 gearing, new chain, tail tidy, chassis protection, TechSpec tank grips, seat cowl, etc.

The bike is simply a dream in the canyons. I mean, these little bikes can be made so good (and with a boost in power) where you may not want anything 'bigger' or any kind of upgrade. On the freeway I think they're still lacking compared to the supersports. So, you not only make the bike lighter with these mods, but faster too. It really starts to transform how it feels to ride it. Just changing the rear tire from the stock IRC to a Pirelli Diablo Rosso II shaved-off 3.1 lbs. of unsprung mass, which is the best kind of weight you can remove. That weight removal by itself improves braking and acceleration for the same reason that lighter wheels improve it, not to mention better warm-up time and better outright grip.

What I've been doing is letting people try my nicely modded 300 and it's been getting rave reviews...and even vlogger BakerXDerek gave it a '10'. But, the same treatment can be done to the R3 to really push the envelope and make it so your bike is totally running sweet, at its max reasonable HP and catered to you. It's hard to appreciate those differences until you experience a bike that's been fully-modded. ;) It's like night and day. In fact, I probably would have sold my Ninja by now if not for the improvement I got from the clip-ons. Those stock bars were way too high for how I ride in the canyons. And, the Pazzo levers made a huge difference from those stock levers with the clutch bite point super far from the grip.

I think the R3 is more refined right out of the box...and some choice mods would have it singing in no time if it's a project you want to tackle. ;)

SpacePoD from riderforums? We meet again lol. Are you contemplating on selling the N300? I sold my ZX6R for the R3. Was going to go with a N300 (would have been my 5th Ninja lol) but it was really lacking for me. I like how the R3 has a better dash, slightly ( you actually feel it though) better power, and is lighter than the N300. I dont think I will go crazy with mods on this R3, I did enough of that on the 650, and in the end ended up with a real ZX6R lol. I ride the R3 for what it is, a fun little bike out of the box.

Riderforums...is there someone using my vlogger name somewhere? ;) I don't think I am on Riderforums. I'm on the Ninja 300 forums though and on YouTube. I can't sell the N300 yet, but if I do I plan to get a 2015+ Triumph Daytona 675R.

I can understand keeping a smaller bike stock...and the R3 is pretty good out of the box. I didn't find fault with the levers (unlike the 300) and the dash is really nice. I waited so long for the small bike market to light up that I wanted to be one of the first to fully-mod a Ninja 300 on YouTube. :)

You know now that I think about it, not sure if it was riderforum or the 300 forums. I am a member of both, but not active in the 300 forums. I joined that one thinking I would buy a 300, but never did.

Ah, yeah I'm a super mod over on the Ninja 300 forum. ;) Been there since 2013 when I bought the 300. These forums are run by VerticalScope, so it feels like part of the family. I'm also on the Daytona 675R forum (my next bike) but I don't really post there.
I have a full exhaust and a custom tune...


I use my bike mostly for commuting to work and the occasional canyon cruises. I used to race motocross and had a cruiser in the past, but this is my first time on a sport bike. I feel like the bike came from the factory as a pretty well rounded awesome package. The suspension and tires could be better, but they are good enough for what I'm using the bike for. I wanted to get some growl from the engine so I dived into the full exhaust. I wasn't really looking for a big push in power. The bike frankly came from the factory with more than enough power for me. I surprised to feel such an increase in power though when I put on the custom map. The tuner claims a 12% increase in power with his map. The power band is completely different now and the bike pulls. The bike is just so much fun to ride and I have even more power to spare. I occasionally get on it. I don't track the bike, but if I did I would have gone a completely different route. The brake lines, suspension and tires would have been first on my list. As a commuter with a small boost of power for some fun..... I'm very happy with the route I chose with my setup.

I wouldnt go as far as saying the suspension is good enough for me, because it isnt. In the end it had to be good enough for the pricepoint the manufacturer set. You cant add cartridge forks, and an adjustable shock while still being within the target price point. Besides minor things like a brake line or pads (which are really just consumable items to me anyways), my first mods to a bike that I plan on keeping will always be suspension first. If you ever have a chance to sit on, and ride someone's bike who is tuned to his weight, and that rider is roughly your weight, take it. Suspension, when done right, is awesome and will probably change your mind in your future bikes on what you want to prioritize your spending on first. My last bike had a good set up from the factory (Showa BPF), besides the springs being a tad bit too heavy for my weight. My bike before that had an Ohlins shock, and transplanted ZX6R forks. Both those set ups put my stock 650 to shame in the suspension catagory.

Even as just a commuter/canyon bike, for me suspension is the best money spent because you can turn it down for every day commuting for more compliance and an overall better feeling ride, then give it a couple of turns for your canyon fix.

My approach was a bit different than yours. I was ok with the power of the R3 for 80-85 mph commuting here in SoCal, with a bit left to just make passes if I need to. Thats coming from a guy whos previous was a bike with 3 times its HP. The brakes however, left me thinking "WTF did I buy?" lol.

I hear you on the suspension.... I've had about 4 125cc dirt bikes back in the day. I ended up buying a YZ 125 from a professional racer. I had the MCR suspension set up specifically for my weight and riding style and holy crap..... my skills on pretty much every part of track were night and day.


My previous road bike was a 2003 Yamaha V-Star 650. EVERYTHING on the R3 is far superior to anything on the V-Star when it comes to performance and that really helps me appreciate my R3 lol

If my memory serves me right, you're the guy with the custom astro full suit right?

Yeah, designed by me (based on the NASA EVA suits) and made by Z-Custom Leathers.
