Anyone ever heard or used these tires on a ninja 250 before ? ; IRC Road Winner RX-01R tires.

I've never heard of a company called IRC.

I ended up getting my rear tire replaced with one of these for a 100 bux . (rear tired hadn't been replaced in 9100km's and there were some nasty cracks developing on the side wall of the tire, pretty deep).

Can't find any "substantial" info on these tires.
 
The IRC Road Winner's come stock on the newer Ninja 250s.

Most seem to dislike the Road Winner's and find whatever tire they get after stock to be marginally better.

Some say they have/had no problems with them.

Depends on how fast you go I guess. If you just commute to/from work/school/etc any tire will be fine. I haven't used those tires so I can't comment on how good they are turning.

Someone on this forum should have some good information about the tires/etc.
 
Thanks for the reply Sabex,

The IRC tire replaced the rear Dunlop GT501 on my ninja 250. I'll check out that link/forum you supplied.
(On a side note, I didn't notice any difference with the new tire , well just ridden it once , from the shop to the house and gonna park it for a few days, looks like its going to be raining for a bit).
 
When I had my 250r , it came stock with the IRC tire. I replaced them at around 12,000 km's. I probably had another 3,000 km's of life left on the rear. The front still looked new. The back was starting to sqare off and I noticed the tire loosing traction on hard braking some times. I hardly rode in the wet with them so I can't give you any feedback there. But for everyday riding and some twisties. They were an ok tire. I replaced them with the Dunlop GT 501. Which came stock on the 2008 model. I only put 500 km 's on them before I sold the bike. But what I did notice in that short time is that they seem to provide better braking and better feedback on the twisties. There is tire review and comparison for the stock sizes for the 250r. The Dunlops came out highly recommended. As far as IRC goes they are fine for everyday type riding.

Pirelli has just released some new sizes of Diablo Rosso II, including little tiny H-rated radials - perfect for Ninja 250!
110/70 R 17 front - Parts Canada # 320105
140/70 R 17 rear - Parts Canada # 320104
Guys have been putting supersport radials on the littlest Ninja already, but I think the 150 rears and especially the 120 fronts are just too big.
These radials however are a good size, much better. A 250 Ninja might actually get a little heat into them!
Also, the Diablo Rosso II uses a dual-compound rear tire. Supposed to work good in the wet.
They sound too perfect; must be expensive...?
 
The IRC Roadwinners also come standard on the Honda CBR250R and the new CBR125R, and I have one of those. I really have no complaints about them for normal street use. They last a long, long time. I have almost 12,000 km on the rear, and it's still good for more.
 
Yes, the Inoue's come standard on both Honda models, and the Ninja 250.
The old Inoue's used to be considered cheap & dirty, but these days IRC as they call themselves make okay rubber.
Have to, to be OEM on Honda!
The little Ninja, the CBR 250 and the new CBR125 are in pretty good shape with a number of tires to choose from.
For the earlier CBR125 there's really only one tire choice - the OEM IRC sold under a Honda part number. Very modestly priced.
Although the bigger IRC tires sold under Honda part numbers are remarkably affordable too, they are no match for Sport Demons, Avon Roadrider etc. in performance.
And certainly the Diablo Rosso II radials would be a cut above all else.
 
I would be cautious aboit using the Diablo Rosso II . Those are radial type tires. The Ninja 250r is setup for byias ply tires. The Pirelli Sport Demons may be a better option if you wanted to go Pirelli.
 
I ran 2 sets of BT-016s in 110/70-17 front and 150/60-17 rear on my Ninja after wearing out the ircs. Never had any problems with them being a radial tire. Just make sure if you're going to go 150 on the rear, you should stick to a 60 series sidewall to prevent really mucking up the profile of the tire. 70 series sidewalls pinch and make the tire a little taller in the center.
 
The IRC Road winners are great commuting tires. I had them in my 2011 Ninja 250R for 17,000km before I sold the bike. The rear started to square off slightly but the front still looked new and both tires were able to pass safety with thousands of kilometres left in them as per the mechanic.

I commuted to and from work everyday in all weather conditions and they performed well as long as you didn't attempt to push the bike in bad weather. If you intend on riding aggressively these tires aren't for you either. They're definitely more of a touring tire than a sport tire because they're quite stiff, which helps with the durability. That's not to say the occasional spirited ride with friends is unsafe, just make sure it's not raining and you're not running cold.


The Pirellis, I have heard, are far superior in every aspect except durability, which terrible in comparison. You can't have everything though, so pick what type of rider you are and go from there.


I hope this helps.
