Modern Vespa

I am wanting to adjust the rear shocks on my 2020 MP3 500 HPE. They are the ones with the red springs. The manual only shows how to adjust the older 4-level shocks, but these are different - they have two adjustable rings.

Help?

Adjust (turn) the upper ring to where you want it to sit, then turn the lower until it touches the upper ring and snug it up. The lower ring is there to keep the upper from turning on its own.

Duplicate for the other side.

Maybe the page 49 in the Workshop Manal help you. I attach a image

Excellent. Thank you both.

I had figured out the two-ring procedure, but there wasn't any indication of appropriate settings.

You have to do the math on this one based on your weight, heighth, vehicle sag (with and without load including driver, pillion), etc.

I would be interested in what formula you use.

Otherwise I'll just try different setting until it feels right.

I simply use the Bitubo guide as was supplied with my Piaggio accessorized shock set. See link, pages 73-75

This gets you in the ballpark. After that, it is a matter of fine tuning for your specific needs

Interesting just measured mine 2020 model stock from factory previous owner never changed anything, rear shocks are at 100mm setting so basically if my calculations are about right good for a 70 to 80 kg rider only, looks like me is going to 119mm as I ride often 2 up and a tad far from the featherweight category.

So shocks set at 115mm tried 119mm was ok but left myself a bit of room, like night and day, thanks for the info guys
