I just bought my Ninja 400r last thursday, heres a pic. Kevin Chmil's Photos | Facebook

I'd like to mod my bike, weight reduction(If possible. I'm a bike noob), get a little more power out of her and some new exhaust. Only problem is, Ninja 400s obviously aren't made in the states so aftermarket parts for them seem non existent.

I've heard 650 parts will fit the 400s, is this true? And if they do, is it good for performance of the bike?

Sports bars
Frame sliders

There are some simple ones zandit put sports bars on his 650 and he said it like the turns slot more

Hey KChmil!
Basically anything sold for the 650R will fit the 400R, so have at it, and you will have a ball!
Weight reduction can be had from lighter wheels, but they cost the earth, changing over the exhaust will save you about 10kgs, and then you could also replace the swing arm from a Kawasaki Versys which is aluminium. Takes a bit of work, but it is do-able.
Check out my thread which shows all of the jobs I have done to mine.

Good luck, and keep us updated.

I'm only 5'7, so dropping the handlebars might make it uncomfortable for me, but those frame sliders might be a good idea. I'm mainly looking into a new exhaust, but I have no clue what I want.

Dude, I'm only 5'6", and I do not have a long reach, but I grew up on 10-speed push bikes, so I was always used to the slightly extended reach, so much so, that when I first got the 650R, my back would ache from being too upright.
Unfortunately when it comes to exhausts there is no right or wrong answer, go with what you like, not what everyone else says is the best. One word of advise though, do not buy the 2Bros Carbon fibre exhaust. The vibration generated by our engine absolutley destroys them, and 2Bros will not honour warranty on them. I chose the Yoshi because it was different in style, and it sounds great. I wanted the Carbon model, but that was too expensive to justify to myself.
As for the sliders, here is the brand I am using, not badly priced, and pretty easy to install.
No Cut Frame Slider for Kawasaki Ninja 650R ER6f Motorcycle 2009-2011 BLACK New | eBay
Check out his other items on ebay, he has a fair bit to offer, and if you damage something on the bike, he buys direct from the Kawasaki factory, and you are not paying the kings ransom from the local dealers. Make sure you tell him I sent you!

Zandit, you've been a huge help, and thankyou for that.

I still have a few questions though. I asked my dad and asked some guy at the kawasaki dealer in my city about a new exhaust (Both really don't know much) They both said something along the lines of, "It might not be good for the motor because the motor needs certain back pressure. That might void the warranty." Whats your opinion on that?

 

[Zandit]

Unfortunately, You could use the same argument for any modification to any vehicle.
Most exhaust systems are designed to bring the bike into line with Emission regulations which are getting stricter each year. They feature catalytic convertors, and are very restrictive.
Many people have told me, if you buy an exhaust, fit it yourself, and keep your stock can on hand in case something goes wrong, then change it back over before taking it in for warranty issues!!

Having said that, We have many dealers here that fit after market exhausts to their bikes on display, so go figure!!

 

[KChmil]

Once again, thanks. But now I have I bigger problem, deciding what colour/finish of exhaust to get. LOL

 

[Zandit]

Mate, I'm not gonna help you there, cause it took me forever to pick one out.
I was bouncing around the Laser, Yoshi Carbon, V&H, Arrow, etc etc etc!!! In the end I love the Yoshi, and while I would have liked to keep the under body look, I couldn't be happier!
Like I said, buy the one you will be happy with, they all claim to bring out the best performance, but they are all very similar, it is just the look, quality, sound and price that differs..........which doesn't make it sound like they have anything in common!!!

dude ive been reading posts about 650r parts for my 400r, i was just wondering if you (or anybody) put an aftermarket exhaust yet, i wanna get the carbon fiber yoshimura. and i live in winnipeg too.

 

[Zandit]

There are a number of guys over on Kawiforums who have put exhausts on their 400R, and they are all from the 650R. As mentioned,these bikes are identical in everyway, except the engine is sleeved to bring it down to 400cc's. Obviously there are some ECU differences, but nothing else.

I'm actually looking at that exact one too. I haven't installed one, but I can almost assure you they work. Like everyone else is saying, the 400s are exactly the same as the 650s.

There's only one thing that might be annoying (to me anyway) I read something on youtube about a chip, something about an O2 sensor that plugs into the muffler that after market mufflers don't have. Apparently bikes in the states don't have these chips so the majority aftermarket ones don't bother to put them on. So the f1 light -- that american bikes don't have-- stays on ( I think its the f1 light? )

You are referring to FI (Fuel Injection) light. The Canadian and Euro/Jap bikes have more sophisticated fuel injection system with 02 sensor than the American bikes. We in Canada have the 02 sensor that screws into a flange before the muffler. I installed the European Arrow exhaust on my 2011 400R and it's wicked!

Have a look:

Can anyone recommend any good websites for buying the mods?
