Tuono V4

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.
