The 2014 Aprilia Tuono V4 1000 has 2 recalls, both concerning a front brake master cylinder that can allow air into the hydraulic system, extending stopping distances and raising the risk of a crash.
When air enters the brake's hydraulic circuit, the front brake lever can feel spongy or less responsive, meaning the motorcycle may take longer to stop than the rider expects in an emergency.
