    More than the local rider of one sports bike at the IoM hill climb in 96
    did at any rate. We tried to tell him. You could still see the outline
    of the maker's label on the brand new back tyre as it glinted in the sun
    on the start line ready for the first practice run. The scrutineer had
    warned him, but he was adamant that the dealer that fitted the tyre had
    told him that these new fangled [insert latest fashion tyres in 96]
    gripped like **** from the word go.

    Start line light goes green. Took off in a reasonably straight line
    without much wheel spin but then came an almighty ball of chalk at
    Stella Maris.

    I haven't changed my tyres, I don't know what they are....and on I'll pop
    into my little garage......190/55's. The tyres seem quite good to me, they
    are sticky when warm and informative when wet. They are looking a bit worn
    though.

    Dual compound rocks. At least from the perspective of aesthetics it
    does, whether they are any good as a tyre is dependant on how they are
    ridden really and if the riding don't match the rubber they are going to
    be shite even if there is a Z in the name.

    I have always hated having the middle of the tyres wear out and there is
    still trace of the hero blobs left on the edges. Pisses me right off it
    does. I feel cheated. Either I have not used them to the full or the
    cunts have sold me something I don't need and as I am a riding demi god
    I can only assume that rip off Britain has scored again.

    It is inevitable really, I do most of my riding in an urbane environment
    and spend much more time speeding up and slowing down than ever I do
    going round corners so all the wear is going to be in the middle.
    Stands to reason dunnit.

    Imagine my joy then when quite a few years ago now that they started
    making them in a size that fitted my bike, at a price I was prepared to
    pay and I was up for a new set. A win win situation for me really. We
    are well into the era of modern rubber and I couldn't remember having an
    issue with grip that wasn't my fault since the last time I was silly
    enough to give it full beans leaving the left side of the Southbound
    Dartford toll booths and wanting to be across 7 or 8 lanes of traffic as
    best I could so that I could get on with the somewhat less stressful
    matter of making progress.

    As to the edges, I don't spend enough time leaned over with anywhere
    near the enthusiasm that I do upright so my experience in that area is
    much more limited, nor do I particularly want to. I am a lazy rider,
    the saddle is put there to sit on not to hang off so I do, so I don't
    corner as fast as others might because of geometry. Although while
    Newton is still on my side I will do what I can, which is why I travel
    closer to the edges than I should considering the speeds I do it at.

    My nervousness about getting into a grip deficient situation is
    addressed when they announce two tone rubber designed with the commuter
    in mind. So I figured that with what I feel is adequate modern rubber
    laid in a strip down the middle and something akin to black Bostik
    around the edges can really only be an improvement and had them fitted.

    Transformed the bike it did but then it always does. The only reason I
    change tyres in the first place is usually prompted by threats of legal
    action if they are ever seen in that condition upon the Queens highway
    *ever* again, so I am not all surprised that there is a huge improvement
    in the handling. Especial the bit where you transit from upright to
    over and back which, regardless of the quality of rubber in contact with
    the ground, is so much improved by a tyre without a flat bit right
    across the middle.

    Having put them on and waxed lyrical about the improvements in the
    handling thousands of miles begin to pass and I notice a different
    pattern to the wear, yes they are going flat in the middle but so are
    some of the sides so it doesn't look as flat as it could and cunts don't
    take the piss about it.

    So there you have it, if you are unsure about anything, be assured; as
    they wear dual compound tyres do not tell the world as much about your
    riding style as do single compound and from what I know of yours, you
    are going to need all the help you can get to keep criticism levels down
    to acceptable levels.

    I considered buying Bridgestones but mine seemed to handle quite well
    on the previous Michelin rear and I already had the front one so it
    was no contest.

    I wanted to try out the dual compound idea as well. I know it's been
    around for ages nut nobody has really tried it with a sticky tyre
    suitable for trackdays.

    Doesn't help - the smell stays in till the waterproofs come off.

    I think the tyres are very sticky, I've cranked it right over on both sides
    and there's tons of grip. However, I don't think they will last much longer.
    1600 miles on a tyre is not good for my finances.

    I've got to admit I love the handling, it's *exactly* what I want a
    sportsbike to handle like... maybe it helps that I weigh exactly 68Kg at
    the moment, so the factory suspension settings are spot on for my
    weight.

    Tyres are going to be a bit of an adventure I think, it's going to be
    guess work until a few brands offer choices in the new size[1]. I've a
    feeling the dual compound michelins[2] will do everything I need though,
    so that's my current idea, probably for when I get back from pound
    island.

    [1] A size that's also used that size on the new Ducati 1098, where they
    fit Pirelli Dragon Super Corsas... so I guess that's another choice, but
    they probably wear just as fast.

    That's interesting. I'm carrying 30 kilos over you, not including
    kit, and I'm finding it ok on standard settings! If anything a little
    on the hard side particularly on bumpy roads.

    They seem to suit the 'Tart'. Mr Auvache has the nub of it though. They
    keep their profile even on a lardy tourer. TBF though, they have done
    three track days in hot weather. They also seem quite good stone cold
    from a standing start. That's partly why I didn't go for a Pilot sport
    even on the front, because my emporium muttered darkly about grip when
    cold.

    Isn't that just the compression damping? I may be wrong but doesn't it
    increase the resistance the harder you compress it?.

    I'm surprised you're getting such crap mileage from tyres on your 10R.
    My original rear Dunlop did 3k miles, the replacement Michelin did
    about 2.8k miles and the front Dunlop did 5.8k miles.

    Those miles included a trackday at Silverstone and quite a few runs
    over the mountain on the IoM where I don't usually take it easy. None
    of the tyres were illegal when changed but were starting to affect the
    handling to a degree where the make felt unstable.

    The only way I'd have minced the tyres in a low number of miles would
    be if I insisted on ragging it away from a standstill and if I was
    going to do that I'd put harder tyres on.

    Reading a couple of the ZX10 boards the consensus seems to be the
    factory fit qualifier hasn't got as deep a tread as the OEM versions.
    Several people have dumped them and gone for Pilot Power 2CTs in 190/50
    (until the 190/55's are out.)

    That said, Molly's probably wasted 1/3 ot the tyre on dyno runs..

    Dyno runs don't **** tyres that much. I had the Michelin on mine when
    it was on the dyno.

    I coulkdn't understand it either, I showed Loz my tyres and he said
    something about them being rather soft. The edges look like I've been on the
    track. The right hand side is noticeably chamferred, probably due to me
    playing a bit on a roundabout.
    I don't take it easy from standstill but I don't hammer it too much either.
    It's not squared off at all, in fact the outer parts of the tyre is more
    worn than the centre. I do love the grip of the tyres but it will become far
    too expensive if I changed them frequently. I got almost 3K out of the
    BT010's on my old gixxer.

  20. IIRC the only trouble with dual compound is that they lay the harder
    stuff over the softer compound. When you think you have 500+ miles left
    on the tyre the hard compound disappears leaving the soft underneath.
    Then you only half what you thought was the remaining mileage.
