Installed Pirelli Diablo Rosso II's on my Ninja 300

Alex · October 20th, 2012, 05:26 PM

Here they are!

Here's where I put them!

First ride on them tomorrow. For all those with a wide tire fetish, the 140mm rear on the Pirellis looks somewhat narrower to me than the OEM 140mm IRC's.

(I'll manage.

)

Alex · October 20th, 2012, 05:26 PM

More pics here.

Will take some more of the tires on the bike tomorrow.

menikmati · October 20th, 2012, 05:38 PM

Looks great, Alex.

Alex · October 20th, 2012, 05:49 PM

When I was putting the wheel back on, I realized that it was a bit out of alignment right from the factory. Was able to get it aimed straight by using the tried and true "count the *@#&*(@# threads" method for the chain adjusters. Will see if it makes a difference tomorrow.

Byakkotai · October 20th, 2012, 06:09 PM

That "other" bike seems to be collecting dust?

Looking good!

Alex · October 20th, 2012, 06:15 PM

Funny you should mention that! We're doing some remodeling, and our entire house seemed covered in dust, including the garage. I cleaned off the 300 as I was riding it the next day, but there is still a good layer of dust on the other two bikes.

Surferboy120 · October 20th, 2012, 08:44 PM

Holy smokes the Corsa II's!!! You will be like velcro on the rode congrats! I went with the Roso IIs and so far I am loving them. I agree with you the rear tire does look narrower than the IRCs did on it. I love the profile of the Diablos though and they allow for the bike to fall all so nicely into a corner.

Alex · October 20th, 2012, 08:49 PM

Nah, brainfart on my part. They are the Diablo Rosso II's, not the Corsas. I don't believe the Corsas are available in 140.

Yes your right the Corsa's dont come in a 140....I am bummed about that too because I like the profile of the Roso II's and would hope the Corsa would be about the same for when I get on the track.

I am sure you will love the Roso II's.

You're right they don't. They do come in a 150. I put a set of my race take off Corsa's on my 300. I still don't think I'll be able to us the whole tire even on the track, but I have no question about grip.

Do you have experience in how different the profile on the Rosso IIs and your Race Corsa's are? I would think its a lot since its the difference between a 140 and 150 but I am curious to find out. I would rather keep as close to the same profile of the Roso IIs in the 140 as possible if possible for track tires in the future.

Also being that the rear wheel is also wider in the 300 I hope the profile will be better if forced to go with the 150.

Thank you in advance.

Peanut_EOD · October 21st, 2012, 06:36 PM

I have used both on the 250, but I haven't had the 300 on the track yet. The 150 on the 4" rim looks about the same as the 140 on the 3.5" rim. I was able to use most of the 140 with the 3.5" rim, but we went to the 150 because of the compound available.

Alex · October 21st, 2012, 06:48 PM

Tires felt good today. Under normal riding, the feel is very similar to the stock tires, in terms of ride quality, and even steering feel. No sharper or heavier. But at high speeds and larger lean angles, the Pirellis are noticeably more stable. I took one corner today (high-speed sweeper) at the same speed as I had a few weeks ago on the IRC's, and noticed that the bike stayed in quite a bit better shape. The rear end felt more planted, and the whole suspension felt like it was working that much better, even with the added stickiness.

One tip - when I removed the axles, they were completely bone-dry, with not even the lightest amount of grease. It was quite hard to remove the rear axle, and took a little gentle tapping from a rubber mallet to get it all the way free. Once given a light coating of moly, everything went together much better (and will likely be easy to remove the next time, as well).

I found the exact same thing.

Thank you that gives me high hopes with going to a 150 for track tires.

Dude, english. WTF did that last post mean?

rusninja · November 5th, 2012, 11:05 PM

I was trying to say that my tire wear is more apperent on the right side of my tire, on the chicken strips there is a little pitchfork design and im close/barely scrubing it and on the left i havent leaned in as much. That sounds so boring >.>

choneofakind · November 5th, 2012, 11:07 PM

Don't worry about chicken strips. All that means is you do nothing with your body positioning.

Correct BP = hawt.

Leaning the bike over when you don't need to = not.

areifel · November 29th, 2012, 12:16 PM

I would never go back to the rock solid IRCs after putting on the DRIIs. Night and day difference!

kooshbox · November 29th, 2012, 11:28 PM

How many miles are these supposed to last under normal riding use? I hate the slip I get with these OEM's with wet conditions and too much lean.

Hey @Alex, what psi are you running?

Alex · March 10th, 2013, 08:28 PM

28f/32r seems to be working fine. Would be interested if people have found what pirelli says directly about these tires. Somewhere someone found what they recommended for the Sport Demons, which I think was 32/36 or something like that.

Got this email reply from Pirelli in May 2012

Hello

Please note one should always inflate tires to the correct tire pressure as indicated in the ownerâ€™s manual. However Pirelli North America has found the air pressure suggestions listed in our brochures will improve mileage and customer satisfaction. Check cold inflation pressure frequently. Correct tire pressure is crucial for safe handling. Over inflation may impair ride comfort and reduce the contact patch between the tire and the driving surface of the tires. Insufficient air pressure will result in poor handling and cause a tendency for the motorcycle to "wander". In addition, improper and insufficient tire pressure will cause accelerated tire wear, increased fuel consumption, less control and the possibilities for tire failure due to an overloaded/under inflated operating situation.

Hyper Sport, Supersport, Extended Mileage Sport radial tires, Bias-ply Sport Touring tires
Front
Solo / Riding with 2 / Riding 2 with extra load
32-34 / 34-36 / 36-42

Rear
Solo / Riding with 2 / Riding 2 with extra load
36-38 / 38-40 / 40-42

In closing Pirelli finds that running higher pressures (up to the max as stated on the sidewall) will increase the life of the tire with no adverse effects. Thanks for the question and have a great day.

Their guidance is better than nothing, but it's still pretty vague. Use from from 32 - 42, and rear from 36 - 42, no matter which of their tires you're using, and no matter which bike they are on.

I don't think I'd want to run them even at 32/36 on such a light bike.

I think their tire pressure recommendations have more to do with overall weight thresholds than individual bike weight.

Dunlop also recommends the following guidelines:

For touring motorcycle loading
A. Light loads-single rider with some luggage (up to 200 lbs total) - minimum tire pressure of 32 psi front and 36 psi rear must be maintained.

B. Heavier loads-dual riding and/or luggage (from 200lb. Total up to maximum motorcycle capacity stated in the owner's manual - pressure of 36 psi front and 40 psi rear must be maintained.

For any dual riding or fully loaded use, 40 psi must be maintained in all Dunlop rear tires fitted to touring motorcycles.

Continental Tires recommends 2.3 bar (33 psi) for their 110/70/17 tires.

I guess it comes down to what works best for your bike, tires, rider and riding style. My 375 lbs bike can turn into 629 lbs with me fully geared full tank bag and a small luggage bag. To me, that's a little more weight than normal for 28 psi.
