Pirelli Diablo Rosso II - the worst tyres I ever had
« on: 16 June 2014, 10:20:53 am »
I've done over 35k miles with my Fazer and changed a lot of different tyres, including Bridgestone, Metzeler, Michelin, etc.
The last ones I had were Michelin Pilot Road 3 (I think it was 3). They were great.
I usually do 70% city and 30% open road driving, they were good because they lasted long and actually handled very well.
I ran them at 2.5bar front and 2.8 rear.


Then I had to change them. Visited a local bike tyre shop (guy specializes for bike tyres). After talking to him, describing my driving habits, etc. he recommended me Diablo Rosso II.
He said they were good all-around tyres and that they will last long.
On the first ride they handled like garbage, slippery, unpredictable. Very unreliable.
I thought it was because it's still new. Gave them a couple of hundred kilometers to "break in".
Nope, still garbage.
I've done ~1500miles on them by now, and they still suck.
They're good when driving straight, but once you start leaning through corners they start slipping unpredictably. They're very strange, in a bad way. It's like that they slip a bit each time you change tilt quickly.
They're also not very good for going fast through long corners while leaning. They constantly slip-hold-slip-hold-slip-hold.


Now, I read reviews on the internet and people seem to be really pleased with them, so I wonder who's crazy here?
I run them at the same pressure as I did Michelins. I found it provides for faster leaning.
They were new when I bought them, I checked the date.


I had to write this because I still can't believe how bad they are, and now I'm stuck with them, which pi**es me off.
They're so bad, that my friend told me he saw them bobbing (letting go) while he was riding behind me last weekend.
Sorry for funny words, but English is not my primary language  :rolleyes

Current tyres from reputable manufacturers certainly ought to give a better result than that.
I wonder if the problem is that the wrong size has been fitted on one or other wheel, or maybe fitted backwards?

Well ive heard mixed reviews but none so bad as that.




I had them on my bike last time & they handled really well, they get really chewed up but are very grippy & i could push them in the dry a little bit further than my current tyres.


My current tyres are pilot 3 and they are also very good...main reason i chose pilots was that they would last longer & are much better in the wet (shame really as with no more than 500 miles on them im now stripping the bike :rolleyes )[size=78%]........but for corners in the dry it is defo  the rosso for me.[/size]

They're not old stock and they're fitted properly.
Dimension is correct too.
Well, that's my experience with them.
I know one thing for sure, never again.
Next tyre is Pilot Road 4.

I get on with them.  Sometimes tyres don't work for people.  Some folk used to rave about some Avons for the Fazer.  I heated them, in the wet I thought they were always going to slip out.  Made for a harrible wet decent of the Col Du Galibier!

Have you tried different pressures? I had Avon Storms which felt dodgy at standard 32psi/36psi I had used with other tyres but once the rear was pumped up to 42psi they were great. Avon Storm 2 when I got them I used 42psi in the back but felt horrible until I dropped it to 36 and they improved.  Most modern tyres have far lighter and more flexible construction compared to when Fazer was designed and seem to prefer running higher pressures

I haven't.
I'm running them at 36 front, 40 rear, which is not little.
Maybe I should deflate them, if so, to what extent ?

Check with the tyre manufacturer as to what pressure they should be run at with your bike :)

I got D.Rosso II recommended for my bike on their website. Weird.
Anyway:



The exact same pressure I use.

Maybe they need tyre warmers ?

They're not delaminating, it's just that they suck.
Too bad there's no return policy for tyres if you're not satisfied...

Not a tyre I liked either, but did not find them as bad as you say. :eek

I found the recommended pressure way to high and dropped them to to 2.2bar front and 2.5 bar rear as a start point to see if they improve if they do drop them to 2.1.and 2.4. Would not go lower than that.

Also found they took ages to heat up. :rolleyes

Finally dumped them and now use either Michelin Pilot Road 3 or Metzeler Interact Z8 with a slight preference for the Metzeler.

Crossans in Norther Ireland are the cheapest I have found for tyres delivered to your door. All you need is for someone to fit and balance them.

How old are they? Have a look for the date code on them (a 4 digit number somewhere on the sidewalls).


As said above, I'd try dropping the tyre pressures too....if nothing else it'll help them heat up more quickly....do it a little bit at a time and ride the same bit of road to see if you get any improvement.

I'll try running at lower pressure and report back eventually.
I'll have to look up the code when I get back home.

Are you sure your rear shock isn't the problem? I also recommend the Metzeler Z8 interact, excellent tyres. My dad has Avon Storm 2's on his SV 650 and loves them, they are a bit cheaper but still perform great and have lasted ages.

It's not the rear shock, although he might have become a bit softer than he was when he was new.
But imagine this, last time we went on a 180-mile trip (open road) and at the end, we were going through some village (higher amount of traffic, a bit worn out road) and they started slipping to the point I could do "S" drifts with my bike.

I've been numerous times on that particular road before, even with former Michelin Pilot 3 tyres, and they would never do that, especially after the long open road trip when tyre is hot and grease-free.

I'll take a look at those Metzelers once I decide to get rid of these, but are they really suitable for my style of driving? I'm pretty heavy on throttle and leaning. Actually, extremely heavy (my footpegs are long gone) and most tyres don't see 9000 miles.
The shortest living tyres I ever had were Metzelers M1 (I think). They lasted 2100 miles, on longer trips they'd grind along edges.

I think the next tyres I get will be the softest grippy-est I can get, not bothered about getting miles out of them or how good they are in the wet, -----which-el-it-be ?
I don't do rain or threat there of. dry rider only with no shame.

I was wondering if the rear shock might be the problem as well, when mine unknowingly leaked a little while back it certainly gave the impression that the rear end was slipping on cornering, as i was literally riding on the spring only, instead of the damper.
I've never known a tyre to be as bad as you say, especially in dry weather.
