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 Tuono V4 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 May 2025, we have one report of a 2026 Tuono V4 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 would be best to try the larger #47 pin first - and then the #31 if the #47 does not fit. We will update this note if it becomes apparent that this was an intentional(and consistent) change by Aprilia for the '26 models.
