Fatter Tires?

I'm thinking of putting a fatter set of tires on my 250. I'm thinking of putting a 160/60 on the rear but will that fit without any modifications?

Yes and no actually...double-check the rim width specs for the tire you intend to use...if the rim is too narrow it will pinch the tire beads and change the tire's profile, or cause it to wear too fast or even blow out. A 160 will often require modification to the chain guard.

So far my own research says a 150 is the max, but even it suffers a small profile change..but it is within the rim size specs.

Check this thread, see post #13 : https://www.250r.net/forum/showthread.php?t=3737&page=2

I would not run a 160 anyways as it will considerably alter the cornering ability of the bike.

I have come to terms with the possibility of dying while riding, life has a 100% death rate. I would rather live having fun and end up dead in a motorcycle crash than never do anything fun because it's dangerous and I might get killed. No one makes it out alive anyway. - From a friend on another forum, used with his permission.

My rims are 17x2.75 front and 17x3.50 back would a 120/60 front and 160/60 in back fit with no problems?

The 120 front is no problem.

The 160 rear will depend on the particular tire you choose. I believe some 160's will be ok on a 3.50 rim, others will not.

You will need to browse the web or go to a place like Cycle Gear and find out the specs on whatever tire brand/style you want to use.

There are a few 160/60/17 tires that can be installed on a stock rim, however most tires in this size are not designed nor recommended for a rim smaller than a 4.5 inch wide rim by the manufacturer. With certain 160/60 tires there will be minimal clearance and removal of the chain guard may be necessary. It is highly recommended that you mount a 160/60 tire on a 4.5" rim (which are available.)

I would highly recommend no bigger than a 140/70/17 tire on a stock rim. In comparison to the average with of a 160/60/17 tire, there is on avg. 1/2" difference in width. Hardly noticeable in most cases. That's an extra 1/2" of tire that will never get used (not even on the track with a stock rim).

There are also a few 120/60/17 tires that can be installed on a stock rim, however most tires in this size are not designed nor recommended for a rim smaller than a 3.5 inch wide rim. Bridgestone makes a 120/70-17 that is designed for a 2.75 in rim. This IMO is the exception.

I'm looking into Michelin pilot road 3s. Any recommendations? 160 or 150

A Michelin Pilot power in a 150/60/17 has been done before on stock rims with no issues.

Keep your eye out for the new Michelin Pilot Street. Specifically designed for lighter weight bikes (CBR250r, Ninja 250/300 etc).

Here is a pic of a 4.5" rim on a Ninja 250 with a Pirelli Angel St 160/60/17



4.5" rim with 160/60 Pilot Power (note the modified chain guard)



Check out Dennis Kirk for real good tire specs & information.

You may also want to Google 'Ninja 250 tire' information and see what other riders are doing on the other Ninja 250 forums.
