LaHaDuc – a Laverda Harley Ducati Bitsa Bike

By Paul Crowe

You may remember the Vincati, a Ducati 750 GT frame with a Vincent V-Twin installed in place of the original engine. Pieter van den Breevaart of the Netherlands liked it a lot, but spare Vincent engines aren’t easy to come by at an affordable price, nor are Ducati 750s, for that matter, so he decided to pursue his goal in his own way and the LaHaDuc, a Laverda Harley Ducati bitsa bike project was under way.

The build began with a 1976 Ducati 860 GT frame, minus the engine, which the owner had used in a sidecar racer. Pieter found his Sportster engine when the owner removed it after ordering one from an XR1200. He found a set of wheels from a Laverda 750 SF, a tank from a Ducati SD500, a seat from a Triumph, and on and on through the endless process of finding and fitting the necessary pieces to make the project complete. He’s been a pretty careful shopper, because the price tag, as of this month, is only 4650 euros or $6144.

Ducati purists can rest easy because no pristine vintage Ducatis were harmed in the making of this project and otherwise unused parts have come together to make a very cool bike Pieter is unlikely to see anywhere else. I like it.

    Nice – maybe it should have LaHaTriDuc on the tank but who cares about that!

    Boranni rims are class.

    Wonder what it’s like to ride?

    Duchaverda would have been a cooler name 😉

    Nice looking bike.. a good mixture of parts
    A high mounted 2 into 1 pipe would look better rather than the drag ones…

    @ Paul Crowe Kneeslider…I think you may have given this build a short shrift. That frame might have started out as an 860 GT, but I don’t recall from memory the front tubes being bent in that fashion or the trailing brake link structure being just so. Correct me if I’m wrong.

    And it is a nice conglomeration befitting a title of Bits of Pieces…perhaps the builder’s munificent multi syllabic name lent an existential influence to the creation?

    I’d suggest, however, from looking at the pipes that either the rider should back of the throttle every so often or do a serious carb re calibration.

    Nice work!

      Those front tubes are new, after the originals were removed, a necessary step to fit the Sportster engine. He details the work on his site. I agree, there’s a lot of work here and nicely done, and within a budget, too.

    Likely those are single wall pipes, no way for them NOT to discolor if you actually ride the beast. I’ve tried all manner interior and exterior treatments….have yet to find one that works well. But really, the colored pipes lend it a little something. Life….
    Great bike and very cleanly executed, well done to the builder.

    I almost missed this. But I got the tip via ‘www.motorfietsweb.nl’Ask the Web. It is that my back is preventing me for riding in such a sporty style. Otherwise I should kill for such a bike! Lovely!
