The minimum height required to comfortably ride super bikes like the Ducati Panigale V4 and BMW S1000 RR can vary depending on several factors, including the individual's body proportions, leg length, and riding preferences. However, as a general guideline, most riders find it more comfortable to handle these powerful bikes if they have a minimum height of around 5 feet 7 inches (170 cm) or taller.
Super bikes typically have higher seat heights, aggressive riding positions, and narrower profiles, which can make it challenging for shorter riders to reach the ground with both feet while seated. However, modifications such as lowering kits or adjusting the suspension can help to accommodate shorter riders. Additionally, some manufacturers offer optional low seat options or adjustable seat heights to cater to a wider range of rider sizes.
If you're considering purchasing a super bike, I highly recommend visiting a dealership or motorcycle showroom to physically sit on the bikes you're interested in. This will give you a better sense of how well you can reach the ground and handle the bike comfortably. Conducting a test ride, if possible, will provide the best opportunity to evaluate the fit and ergonomics of the bike based on your height and riding style.
