Tuono V4

Aprilia Tuono V4 Motorcycle Stands & Trailer Restraint Systems
The pin sizes are listed because of inconsistencies by Aprilia on the steering tube across the range of RSV4 models. Pit Bull's exact pin specs are proprietary information, but use the guide found in "click here for year model specific info" or our fitting chart to be sure you get the right pin. We do not cover any costs associated with returns/exchanges on Aprilia front pins due to their inconsistencies.
As of August 2025, we have multiple reports of 2026 RSV4 Factory and Tuono V4 models having the smaller steering tube diameter found on the pre-2021 Tuono V4 although that may be an inconsistency rather than a full-on change. The pin size difference is tiny(but critical), but we believe the #31 is most likely to fit. If you have fairing contact when you insert the #31(or any) pin, do not lift your motorcycle. You will likely damage your motorcycle if you do. If the #31 is just barely too small and you have fairing contact, the #47 will likely work - as it did on the '25 models.
