I have a YoYo slipper clutch for my RC390. I’m selling the complete unit including the OEM outer clutch basket and a set of steel plates. It’s literally plug and play. All you need are a set of frictions for a 2015 or 2016 390. This will bolt up to any of the 390 Duke or RC390, although I’m not sure if it works with the 2022 and newer RC. These are $900 new. Mine has one season on it and I pulled it out of the bike as I’m selling the bike but pulling a few parts off it to sell separate. This is one of those items. If you want a slipper then here it is. I’m asking $650 for this. That’s a hell of a deal. You can reach me at 317.513.4358 or at shamrockcycles @ yahoo dot com.
