abdecal Posted April 4, 2012 Report Share Posted April 4, 2012 Does anyone know for sure how wide of a rear tire you can put on a 2012 Ninja 250r? I tried researching this but some are saying they have 170 and some are saying a 150 will not fit. Need some help! (130 is stock) Quote Link to comment Share on other sites More sharing options...
abdecal Posted April 4, 2012 Author Report Share Posted April 4, 2012 Caught this quote from an engineer on a Ninja 250 site... Would you agree? Keep it stock?I'm an engineer and I'll tell you to keep the stock sizes. There are so many things that go into designing the suspension on a motorcycle and the tires are part of it. You change that and everything gets outta wack. When they redesigned the R6 to give it 70 sidewall tires instead of 60 sidewall tires they had to redesign the whole suspension system and geometry just to get it to handle right again. If your not an engineer and plan on re-engineering the whole suspension I wouldn't change the tires. Quote Link to comment Share on other sites More sharing options...
Dying Shadow Posted April 4, 2012 Report Share Posted April 4, 2012 Id stay factory its that size for a reason. Quote Link to comment Share on other sites More sharing options...
imprez55 Posted April 4, 2012 Report Share Posted April 4, 2012 (edited) Why do you want to switch from a 130 to a 250, what is the perceived benefit to you? I don't think I could believe it would fit without pictures either; in fact I doubt you can even get a rim that would fit that tire in the swingarm (250-130 = 120mm == 4.72in)-Edit-I misunderstood the title (250 is a standard rear tire size) but the point still remains; why are you trying to get a bigger rear tire on your 250r? Doing a little guesstimation math, the 150 should work no problem at least but I'm not sure I would recommend it. The wider rear is usually meant to keep the rear planted with more power (which you don't have) and adding more tire will add more rotational mass (thereby decreasing acceleration). As said above, the bike was designed in many aspects with stock parameters. Although it was not designed like a supersport, it was still thoroughly engineered that way for a reason.

drew95gt Posted April 4, 2012 Report Share Posted April 4, 2012 I went with 1 size wider than stock on my 2004 250R that I had and it fit ok. There is no reason to go much wider than that since the tire will be pinched on the rim and wear and handle incorrectly. A 130 to 150 is more than adequate for street riding unless you are just going for looks. If the 130 didn't work well on the bike, the factory would have never put that size on to begin with.

Bad324 Posted April 4, 2012 Report Share Posted April 4, 2012 isn't the tire on it brand new?Personally, I wouldn't spend a whole bunch of money on the 250 because i'm willing to bet next season you'll want to get rid of it Quote Link to comment Share on other sites More sharing options...
magley64 Posted April 4, 2012 Report Share Posted April 4, 2012 stick with stock tire sizes... there is no good reason to change it. Quote Link to comment Share on other sites More sharing options...

I wanted to go with a wider tire for looks mostly. But I think you're right, I will probably be in the market for a new bike next year so no need to drop money on the 250. Don't get me wrong, I love it, but as I get more seat time I will want more power. Quote Link to comment Share on other sites More sharing options...

wht_scorpion Posted April 4, 2012 Report Share Posted April 4, 2012 My girl want to go lower side wall but I would not go wide back tire. Unless you think you are going to need a float in the swimming pool. LOL Quote Link to comment Share on other sites More sharing options...

abdecal Posted April 4, 2012 Author Report Share Posted April 4, 2012 After some research into the subject I found it can inhibit my safety. Safety is more important to me than the bike looking better so I'm not going to do it. It's to bad though, the 250r looks like a bicycle from behind,lol Quote Link to comment Share on other sites More sharing options...
wht_scorpion Posted April 5, 2012 Report Share Posted April 5, 2012 It would look like a big lime all that green. Quote Link to comment Share on other sites More sharing options...
Tigerpaw Posted April 5, 2012 Report Share Posted April 5, 2012 Changing tire sizes will effect your handling/safety. I would NOT recommend.If you are already considering a bigger bike don't put a penny into the 250 beyond maintenance and upkeep. People want to buy stock used bikes!I had fun putting money into my '08 250r. In the end though, it was still a 250. That being said, now that mine is gone, I want another stock one. They are a blast.Not sure what other sites you are on but I liked ninjette.org and kawiforums.com. Quote Link to comment Share on other sites More sharing options...
Bad324 Posted April 5, 2012 Report Share Posted April 5, 2012 People want to buy stock used bikes!depends on the person and mods. I'd much rather buy an already modded bike if they are the mods I want. The seller has already incurred the cost of parts and labor and I don't have to do shit. Also makes it easier to resell in my experience. The longest its taken me to sell a bike was my stock 636 Quote Link to comment Share on other sites More sharing options...
