Aprilia RSV4 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 January 2026, 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), so it appears that the #31 pin is correct for this model but *important* to check for fairing clearance before you lift the bike. The #31 is smaller than the #47 so if this is another inconsistency from Aprilia, you do not want to lift the bike if the #31 pin fits loose in the hole and allows fairing contact.
