I bought my 250r back in September and and after 10,000 miles I am ready to replace my IRC tires. The rear is pretty square and almost out of tread. The front still looks like its in good shape but is starting to get tiny heat cracks where the tread meets the tire and with summer coming i decided to try something new. I did some research and found only a few companies produce tires in the 140/70/17 size. I may not have them all but the ones I did find were Bridgstone, Michelin, and of course IRC. I was wondering if anyone has tried any of these tires on their 250r or perhaps other bikes and if so how they liked the wet/dry grip, performance, and handling of the tire.

I changed to Pirelli Sport Demon (stock size) at 18,000km. I also changed the front brake pad at this time.

The difference is un-describable.

Could go through bends 20% faster. Stop on a dime. They inspire lots and lots of confidence.

Probably the best mod for this bike.

No worries.

I'm just short of 30,000km so I've 12,000km on them and there's still no need to think about replacing them.

And I'm not one of the 'going above 8000rpm is bad for your bike' kinda riders.

It appears that the Bridgestone BT-003 sport radial is also available in 110/70 and 140/70, at Bridgestone BT003

If tire lifespan is important, I doubt you'll get 10,000 miles out of those.

You wont even get 1000 miles out off 003's
specialist track tyre only.

There are far more suitable Bridgestone options for road use.

I didn't think Sport Demons would last that long..

hmm..maybe I will add that to the list of possibilities for my next tires.

I am definitely not keeping the IRCs. I changed them out on my Ninja to BT45s and they made a world of difference.

Michelin Pilot Activ's

Anyone ever try Michelin Pilot Activs before?

Just curious. How long are they supposed to last?
I ended up going with the Michelin, $200 to my door. In about 6 months I'll have put 12k more miles on the bike and will be able to report life expectancy on an aggressively ridden bike; very hot/dry summers, lots of stop and go, and always hard in the turns, braking and accelerating. I'm very interested in trying the Demons next time around just to try a nice range of tires before I settle on something. I also had a hard time finding Metzeler Lazertec tires here in US but didn't look too adamantly. I didn't look into Avon tires either, as I do not hear a lot of people raving about how awesome they are.

I'm quite surprised myself. My Michelin Pilot Sporty on another bike were done in under 10k km. I was expecting these to do about 12k km. I've that on them now and expect to change them at 18k km without worry.


Good tyres are like a Full HD LED TV, you don't know how good watching TV can be until you get it. Then you can never go back. :)
