250r with a ZX-10r wheels?

So a friend of mine is looking to buy a used 250r as his first bike. He found one that is selling for 3500 and has 1854 miles on it. The thing is the owner claims the bike has zx-10r wheels and a zx-10r rear seat cowl. He told me this and right away I told him not to even look at it because I beleive to fit a rim that is bigger than ours you would need to do some heavy customizing(some work to the swing arm as well as other things) and I couldn't even see how a 10r seat cowl would fit on our bikes...let alone see the purpose of this. He then said that the bike wasn't modified at all to fit these parts! What?! Now that doesn't make sense to me at all! The owner of this bike also has a airbaged 'busa so I feel like this guy cares more about customizing and showing bikes than actually riding them. So my question is...is it even possible to pur zx-10r wheels on our bike with no custimizing of any kind? I couldnt even see why someone would want to do this.

if a 150 tire has a hard time fitting w/o touching the swingarm, I doubt a massive tire would without a major reworking of the swingarm.

take something as simple as the axle... I'm sure the 10r axle is way to big to fit the stock 250 swing arm and I'm sure the stock 250 axle is too skinny to fit the 10r wheel.

pictures would prove how great a bike this is or how much of an abortion.

ask your friend to go get some pics.

Alex should be chiming in soon, as he owns a 10.

I just measured my 10R rear wheel to confirm, and it has a 6" wide rim. I believe the ninjette has a 3.5" wide rear rim. In terms of fitting between the swingarm, it's not just the width of the rim itself; there's the sprocket assembly on the right side and the brake/caliper on the right side. The caliper mount is actually pretty wide on the ninjette, so with a custom caliper mount (or by ditching the rear brake), it may be possible to fit a significantly wider rim in there. Let's see some pics.

EDIT: I didn't check the front of the swiingarm to see whether a 190 would fit there without rubbing. With what Kelly's saying about a 150 rubbing the swingarm, seems to me a tire that's 40 mm even wider would have quite an issue.

so, you're saying the seller is full of crap?

let me amend my 150 statement to say a 150 will barely fit as is. I can't imagine anything wider being able to fit in the stock swingarm. I know Richard uses a 150 racing tire and it works for him.

All bike sellers are full of crap; it's figuring out the level and quantity of the crap that's most important.

haha so basically you all just confirmed what I though...this guy was full of ( no smilie of poop so this is the best I could do). My friend should be coming into work soon(where I am now) so I'll talk to him so atleast we can see some pictures. Either the guys lying to my friend and its just a 250 rim or he's lying about the extreme crazy mods he did to make this happen(which I dunno why someone would go through all the trouble of doing them and then denying it) I'll find out soon

Just measured mine. With a 150 there is still 1/2" on the right side and 3/4" on the left on the swingarm. So to answer the OP's question, at the very most a 170 tire itself could fit in the swingarm depending on the manufacturer and the aspect ratio of the tire. Unfortunately even that would require modifications because you would need a wider rim and everything else that comes along with it. So no, its not possible to fit a 190.

... and I've read where people tried 160s and rubbed. I think tire brand and aspect ratio has a lot to do with how big of a tire will fit in our swingarms.

I agree a 190 will never fit. maybe the seller has 10r rims and smaller tires on them?

pictures!!! we need pictures of this bike for sale!

Right, but that swingarm wasn't modified so much as it was completely replaced with an R1 swingarm.

I thought you could already fit a 150 rear tyre without any modifications.

Yeap, you're right Mike, but according to the writer, "But just put a wider tire on the rear 3.5" mini rim is not a total solution.Accept for the balloon look we gain very little,if any,out of that big tire." Not sure how truth is it but just post them to share.

Why not just get some IRC SP10 150/60R17. They are made for a 3.5" rim and wont ballon. Plus it is almost identical to facroty height. I just used Amazon and found some in a sec. http://www.amazon.com/TIRE-SP10-150-...9339055&sr=1-7

Hahahaha....good one.

I almost bought a bike from a Nigerian prince. It was an amazing deal. But, the prince went broke because he tried to invest with Madoff and..uh...that didn't work out too well. The Nigerian prince then got a bit of fame on MSNBC's "To Catch A Predator."

Last I heard, the Nigerian prince secured at job at AIG.

Haha srry to keep you guys waiting...been pretty busy with school and work. Contacted the guy yesterday about the bike...said I wanted to stop by to take a look at it and was pretty interested...said the 10r wheels were going to be a main selling point. Well somehow the phone convo got cut off. And it seems like hes been busy ever since and hasnt gotten a chance to return my calls

But you do know that if you were to change the tire size, the bike's handling would be totally different, and as many people have said you would lose it's 'flickability'

It's like this. If by stable, you mean less nimble, then sure. Go as wide as feasible, wider and flatter the better. At the extreme there are those who put car tires on the rear of their cruisers, which are so stable that the bike doesn't need a kickstand when you park it, just stop and get off.

Going wider will not make your bike handle better, it will handle worse. Going wider will not make it any more stable if by stable you mean better handling and feel when leaned over. Going wider will convince nobody at Starbucks that your bike is exactly as blingworthy as the chromed R1 parked next to it with the custom swingarm so it can fit a 240mm back tire. There isn't a single female (or male, for that matter) who will think more of you because you have a wider tire on the back of your 249cc motorcycle. And god forbid you actually find such a female (or male), they have immediately demonstrated to you that they are too dense to concern yourself with, even momentarily.

Alex i agree with your view but at the same time i am not trying to have a bigger tire to prove someone anything, if i need to have big tires then i can just ride my CBR but it is just that i dont feel too comfortable with those tires that is all

Many people believe/say that having a wider tire makes your more stable on the road? Any truth to that statement? I wouldn't have a clue
