    Just a bit of useless info, but wheels having spokes does not by itself indicate a tubed tyre. My old Honda SL230 (grey import) had a spoked, but tubeless rear wheel/tyre as standard. Don't know how they did it, but there you go.

    Hmmmm the plot thickens !

    Did the spokes go through the rim or through a lug on the rim ??

    BMW and I think the Aprilia Campernord have spoked wheels with tubless tyres. I think they achive this by the spokes exiting the rim on its edge.

    Doesn't it say on the sidewall of the tyre whether it's either way?

    Most of the tubeless tires can ran with a tube in them.
    as writen above by keithc there is spoked wheels with tubelees tires.

    I've run tubes in tubeless tyres as a temporary puncture repair, but there can apparently be problems with running a tube in a tubeless tyres down to the tyree construction and heat build up.

    Works good in the Pegaso factory, i do not belive they (Aprilia) will
    put a tube in a tubeless tire if it was unsafe.

    I read some where that as long as you change the tube every time you change the tire all will work fine.

    Regarding my post on "spoked and tubeless", I looked at some pics of my old Honda SL230 and the alloy rim had cast lugs that held the spokes, so that explains how they did that. Just for interest, my SL230 was not a half bad bike. Enduro style, not a million miles away from my Peg Tail in some respects (!?!) Very unique (never saw another on the road), and in 3 years and 20k miles it never once missed a beat.

    I wanted to replace because of the mileage and impending work looming-up to maintain it (clutch, brakes, tyres). I liked the "sit up" style of the 230, but it is a physically small bike, was under-powered (lucky to see over 70mph), had a tiny tank and fairly thin seat. The Peg seemed to answer all these things even though I would still like an even bigger tank range (we all hate having to fill-up, I'm sure). Its a damn site more fun as well!!

    I hope the Peg proves as reliable as the Honda.

    Some tubless tyres are unsuitable for running with tubes in. Normally it will be found in the catalouges, that they do a tubless and a tubed version of the same tyre.
    I was told some time ago that this is in the main due to the moulding in the inside of the tyre. A rough finnish can chaf the tube and eventually cause tube failure.
    Could be wrong of course.

    My mate had an SL230 at the time I had my Vigor SL650, we took them both to Belgium to a see a bike show, I can verify that 70mph is about flat out.On returning home it was geared down a tooth at the front and it was transformed. On the subject of wheels, Beta trials bikes have used the flanged rim idea since about 1992ish to allow tubeless rear tyres, It's still used today by Honda/Montesa

    Back to the thread. I done 130 miles today all of them on twisty b roads. These Continental Sport Attacks are something else. I just cannot get over how much grip the bike has. Even when getting too excited and running it in a bit hot and trailing a bit of front brake it was perfect. No movement at all. I was even trying stupid things like on a 180 deg 2nd gear right, bike banked right over i just cracked it open. The Diablo's would move around a bit, these just gripped and launched the bike forward. It was like hitting a berm on a motocross bike and getting ejected out the turn.

    Will someone else please buy these tyres to see how great the are.

    OK, so far the only candidate seems to be the Conti Sport Attacks. Anything else out there someone tried?
