  1. Hi
    I recently purchased a 500 SD but it is black and white. Do you know if any came out as black and white. Great site guys.

    • Hi John,
      As far as we know black and white was not a standard colour scheme for the PT’s. Black + white was used on a bevel 750S prototype, and black + gold, like the 900SS bevel, was a colour option for the (350) GTV model.

      Perhaps its a custom paint job.
      Is the bike running?


  2. Hi Andre(and other Panigale Twin enthusiasts)
    I am putting back together a 500SD that someone took apart many years ago. In the process they lost all the rocker arms and the cam chain tensioner assembly !!
    I have been able to locate a second hand tensioner and some NOS opening rockers but in looking at the workshop manual I am at a loss to understand how the tensioner is held in place in the cylinder casting. What holds it in place ??I can’t see any pins in the parts diagrams.

    • Hi Mark,
      The cam tensioner should have a hollow dowel with the upper top edges chipped off. In these edges comes a rubber part which has a flat part on the top and round section on the bottom.
      In the cases at the back, when put together, you should see just in front of the 2 M8 threaded holes, 2 notches. the tensioner (with the hollow dowel and rubber edges) sits in the 2 notches and is held there by the cylinder block when tightened down.

      next to sourcing the missing rockers, these rubbers are a challenge to find. I have had to make them from old shoe soles!
      Hopefully this helps!

      let us know if you need more information.

    • Hoi Dolf,
      Zag hem staan op de website, als het de GTL in Meerlo is.

      Moch je deze aanschaffen en een krukas nodig hebt, heb ik er een liggen.
      Laat maar horen via email als wij wat voor jullie kunnen betekenen.

  3. Hi André, I haven’t seen you since the Multistrada meeting at Bulingen a couple of years ago but I found a load of parallel twin stuff on ebay and thought of you.

    None of it may be any good but it’s worth a look,


  4. Hello André,
    Thanks for a great website and all your efforts. I live in the UK and last year I bought a Mototrans 1976 500 GT(L) from a guy who imports ‘barn find’ lambretta scooters from Spain. He found the 500 GT in one such barn and I bought it from him for small money. The engine works fine and even in its sad original state, I rode it down the road and back! it had only done 10k km and then was clearly locked away! I am slowly cleaning, replacing and restoring it, and am happy to send some pictures.
    My questions is – do you know what other fuel tanks could fit on it? The original Mototrans tank (as was their tradition) is butt-ugly and plastic so it has to be replaced. Everything else apart from the equally ugly exhaust silencers, is fine and looks brilliant after a bit of work.
    Many thanks, Steve
