    Chain vs belt

    Today I was at my local dealership getting a service done and while wandering around looking at bikes I noticed the Ducati Diaval was chain driven while the Xdiaval utilizes a belt. So I'm curious why Ducati went with the belt on one bike and a chain on the other since they are essentially the same motorcycle.

    Chains don't rob as much power as belts do, and belts require relatively large pulleys that don't always fit the bike or the intended design. Sprockets can be easily swapped to change gear ratios.
    Belts do last a lot longer, though, and don't need as much maintenance (no cleaning or lube, they don't rust). They're also lighter than chain, so less unsprung mass.
    Shaft drives last nearly forever and don't require much maintenance either. They are heavy, though, and rob more power than belts do. Good luck changing gear ratios.

    Great information and thanks.

    Marketing - the Xdiavel is marketed to the cruiser community - hence a belt they are familiar with

    And I am shocked at the cost of a old tech bulky Harley ( paying for tradition ) compared to the value and performance of a Diavel

    Another difference, since the belt cannot be broken and put back together like a chain, some bikes - like Harleys - need the entire swingarm removed to replace the belt. Belts do last a long time but can be a real pita to replace depending on the swingarm design.

    I've owned a couple of Buell firebolts in the past with the belt drive. I'm a big fan, no chain lube all over the back of your bike and therefore easy to clean the back wheel etc. I'd like to see more bike manufacturers adopt belts.

    They do...its called Scooters. The rest of your complaint is non sequitur especially when there are shaft drives that are better than both. Of course there is the weight penalty and the rear suspension. Ever launched or ridden a Vmax at full song?? Chassis is going 5 different ways under hard acceleration.
