150mm rear tire on 2008 Ninja 250r : Kawasaki ZX Forums: Kawasaki Ninja Forum

BST001 · 05-18-2008, 09:05 PM

Hey guys,
A friend of mine stuck a 150mm tire on his 2008ninja 250. Looks a ton better than the stock 10speed bike looking one that came on it. I was wondering how wide can you go without needing to mod the bike? Thanks!

Scabbs · 05-18-2008, 11:04 PM

dang, thats a ton bigger.

im not sure you can go much bigger.
doesnt it have a 120 for the rear?
surprised you fit that on it.

post a pic man

the widest you can put on there is a 150 according to the Perelli guys at the track. Putting anything bigger on it would be over kill.

I think stock rear is 130. My *guess* is that a 150 is the widest you could put on the stock rim with the stock swingarm.

Doing so will make a noticeable change as to how the bike handles (in terms of flickability).

Ive heard some mixed things about putting the 150mm on the bike. My buddy says he doesnt notice a difference in handling or acceleration, but then I read on other forums that you can notice a difference. (maybe hes just saying he doesnt notice it i don't know) Anyway, before I do it to mine, do you think it will be an unsafe and/or bad modification to do?

My old GS500 had a 140 on it (130 is stock). The only reason to go to a thicker tire on a 250r on the street is for looks.... i.e. to make it look more like a 600/1000 supersport.

As long as nothing is touching/rubbing the tire, chain, or swingarm then it is 'safe'... but I can't think of it offering any advantages to the bike. There will (in theory) be more contact patch available, but the profile of the tire will have to be fairly tall (since you will be using the same stock rim).

150mm is still a long ways off from 180mm (which is what the SS bikes rock). I would go to 140mm to play it safe. If the skinny tire really bugs you that much then get a more powerful bike like the 650R

I ran a 150 on the 08. It is safe and handles just fine. I didn't notice much of a difference other than the tread compound. You will have a better tire selection with a 150 as far as "sticky's" go. Otherwise, there's no point.

yeah I guess my main reason for going with a 150mm would be for looks. What do you think about the Michelin Pilot Activ 150/70-17 for a 250r? Think itll be ok?

the stock is a 130/70-17. If you go with a wider tire, you need to go down in profile. you would have to go with a 150/60-17 or even a 50 series.

Gotchya, is that what you ran? 150/60-17?
Thanks for all your help

SLIDER · 07-25-2008, 01:38 PM

I think so. I had the perelli guys put on the stickiest tire they had that would fit. I know it was a 150 and I'm pretty sure it was a 60 series...it would fit a lot better than a 70 series

IVANRULES · 07-27-2008, 05:19 PM

here's mine!

150/70/17

BST001 · 07-29-2008, 07:48 AM

Thats sick dude! Is that the Bridgestone Battlax BT021? looks great. Also did you have your dealer put it on for ya? And how does it ride?

The tire is A Bridgestone 150 / 70ZR / 17MC

as far as installation, i went to a local motorcycle shop and had them install it for me. At first they told me that it wouldn't fit, but i insisted that they install it anyway, because it knew it would fit. Anyway this mod is VERY COOL but, The guy that installed this tire for me brought up a good point, i am not a very big guy, 5,5 135lbs the tire clearance is not much at all and if you are a bigger guy the tire will flex while cornering, causing it to rub on the swing-arm. in my case because I'm so small it is no problem at all. The ride is sweet! much better balance. If you are looking to go bigger on the tire and still want a good tire clearance it would suggest a 140 tire. The 150 tire fits with no modification at all just in case your wondering.

apeman · 09-06-2008, 06:06 PM

hey just wondering did u change the front tyre too or is it still the stock 110?

is there a need to balance the tires out more in terms of size?

e.g 110, 150 120, 150 etc...

IVANRULES · 09-19-2008, 09:59 PM

i kept he same tire in the front..but i should change it to a bigger size...as far as balancing ....i don't know much..
