This is the Discontinued Ninja 500 (1987-2009) and it had some pretty good Specs for its production time and performance. It is Interesting too because the New Ninja 400 has around 45+ horsepower and with a few Mods it should surpass the Ninja 500 in all around handling and performance. It seems that all that Bikes that are made now have around the same power as the ones that are about 100ccs bigger in the not so distant past. It makes me feel really good to see the NEW WAVE Technology is making even a smaller Motorcycle like the Ninja 400 to have even better or the same as performance as the Ninja 500. The Insurance and fuel Mileage is much better and made in a very neat and good looking package. Like I shared in my last post. I almost bought a Ninja 500 about 2 years ago and really glad that I did not do it and held out to buy a much more High Tech smaller Bike that does better at the same job performance wise. But I will say that the Ninja 500 was no slouch and could hold its one with what it was!.

kw per ton using my weight =

ninja 400 : 148
ninja 500 : 138

In comparison of the Ninja 400 vs the Ninja 500, the forks for the 400 are larger, has fuel injection, led headlights, but in fairness the 500 can be purchased used locally for $1995 and up to $2700 (which is half the price of the 400)lain:

Just wanted to be fair and also post the current Data on the New Ninja EX400 HJ. Really the far better Technology and my current choice for sure..But I would give each Bike 5 Stars in Quality and Reliability. We yet to see the long term Track Record
of the New Ninja 400. Maybe a year or so from now we can give a more accurate assessment...

I was impressed with that clip of the 500 going through the gears! Sounded pretty good too.

I have a friend who has 4 ninja 250's as myself (Miguel from Ninjette.org and presently customizing a red frame 250, pic included), and may be visiting this site from time to time to review everyone's comments. He has been talking about getting a more dependable bike and even mentioned the Ninja 500 upgrade when I upgrade to the 400, (as I am to be able to go to local dealer this week when the 400 arrives in stock finally). If he doesn't want to make the jump to a 2018 400 bike with newer technology, the 500 would be a comparable option for him.
There is a group of racers around New Hampshire that race the ex500's I am told. I read an article detailing how dependable they were for racing and what a dedicated following it has there, though I wouldn't know myself as I have not ever rode the Ninja 500, nor watched them race.
There was another friend who owned a yellow ex500, which he was not that aggressive of a rider and was like riding with grandma when we rode together. So I never really knew the capabilities of the ex500 from watching him. It was a nice bike though and a solid ride.

I thought I read that parts for the classic 250 and 500 Ninjas were starting to get harder to find.

You are correct Sir

I thought I read that parts for the classic 250 and 500 Ninjas were starting to get harder to find.

I can only agree as I have been trying to purchase a rear wave rotor for an ex250 and had to succumb to purchasing a close fit and then I will need to machine it to install. I tried various other routes, even S3 performance out of Australia advertises one, but cannot deliver as their manufacturer has stopped production (they tried very hard though).
The ex 250's can be picked up for a song though. I saw one on craigslist yesterday with 179 miles (total actual miles) for $1200 usd.
I purchased a 1000 mile bike in December for $500 usd. Hence I have too many 250's, but I get some kicks out of customizing my green one (see attached pics)

I went from 89kgs since 2017 june to 69kgs today. And i gotta say that ninja 400 acceleration is bs. today is the first day i really hit the throttle "couldn't wait for engine break in any longer" and I can say now im sure this bike can hit under 4 seconds. the pull at 7500rpm is really awesome for a smaller bike really a lot more than I first thought, on the gps i was hitting 4.3 seconds 0-100kph im thinking with some practice, some weight drop and maybe in the near future a quick shifter i can get it under 4 seconds, either way I have also noticed that the engine feels smoother the more I ride her, after the first 400km she feels more powerful idk if thats in my head or what but its feeling really nice, ill try and do a 0-100kph video within a couple weeks just need a little more engine break in time. bike is now my favourite commute bike due to the power band, very smooth down bottom though does vibrate after 6krpm but when you are in 6k you are already going to fast for basic commuting

emud, Thanks for the info, I would imagine the engine is loosening up a little during the breakin period and you are correct, running smoother. The acceleration sounds great for a 400.
I saw where steelhand in a post was looking forward to the video to be able to hear the sound of your slip on addition, as well as myself.
Safe riding and I hope you don't mind the additional nudge to post a video!
