Looking to add some adjustment and comfort to my ST3 Any ideas and thoughts welcome Thanks These look good https://www.probrake.de/Clip-on-handlebars-REVO-Touring-XL-for-Ducati-ST-3-S-06-07-S3 These also look like a viable option https://www.ebay.co.uk/itm/26670233...lN60w--7KYozgZuXUgLrvk6Mr1BWjmWhoC_oAQAvD_BwE
I had Helibars on my ST3 but they weren't comfortable for me. I saw the first ones you refer to on my search, but eventually I ended up buying the ABM Superbike conversion top yoke, I can now fit the riser and handlebar combination that suits my riding position. Or you could buy a second hand Monster top yoke which would fit too.
I went with the ABM top yoke super helpful seller - stopped fiddling now and riding to work meetings as much as possible
