    New variator for Vespas

    We have had Malossi and Polini variators around for years, and Dr.Pulley sliders as a much cheaper alternative. Now Dr.Pulley has come out with a variator specially designed for their sliders. This is what they posted on Modernvespa forum -

     V201503 is Dr.Pulley's new variator specially for Piaggio 4t 125 to 300 scooters.
    This new V201503 can be installed with SR2015 or SR2115 for 125/200 and 250/300 differently.
    Here's one video about V201503,HiT211701 in LX150.

    Please contact Dr.Pulley's agents for detailed.

    It seems the sliders can move further in to the centre, giving a lower "low gear" for take-off, while also adding a bit at the other end for top speed.

    Here is a link to the article and discussion.

    I have great expectations for this variator, and in conjunction with their HiT clutch should do everything you want for your transmission.

    I have the Polini six roller now, and I know I could get a bit more by fitting sliders to it, but then I have to fiddle with slider weights and fuzzy washers again to tune it correctly. Sliders in a Piaggio variator give you almost as much as the Polini at a fraction of the cost, so I expect a variator designed for the sliders would do even better.

    My Polini variator rollers rattle a bit at idling and take-off. I know sliders would eliminate that. And I believe the Polini nine-roller is smoother than the six-roller. So there are many options for improvement over ther six-roller, good as it is.

    it would be intersting to try. i wonder if it keeps the belt from hitting the oil sump gasket like it does with dr pulley sliders in a malossi variator.

     I'm curious about how it copes in the other direction. It has a lower "low gear", meaning the belt rides lower in the variator at idling and take-off. This in turn means it rides higher in the driven pulley, and the belt could rub on a stancion just behind the clutch/pulley, resulting in a loud squeal. Done that in my expeiments with Polini variator, sliders and fuzzy washers.

    The Malossi belt is higher, and more prone to these problems. I stick to standard Piaggio belts.

    the malossi is crap

     

    i have the malossi, with the lighter weights it revved like crazy, the heavier weights and its not much different to stock i believe

     

    and mine rattles like a tractor, i hope its the crap malossi variator

     

    what about J Costa, is that sorted for the 300 yet?

     

    they any good?

     

    ive just put on a 140 rear tyre and have lost a tiny bit off the line, wheelies arent easy like before, maybe this dr pulley seems the go

     

    local suppliers? or online link?
