The seat height varies according to the rider’s weight, the suspension and its settings. In addition, the seat height will depend on the type of motorcycle; trail bikes are generally higher than scooters or custom bikes.
Seat types change depending on the type of bike and the use for which they are designed.
Thus, the HARLEY type custom bikes have lower seat heights because the motorcycle is intended to have a low center of gravity to facilitate handling, given its high weight.
Naked bikes, such as the
or the YAMAHA MT-07, usually have seats that are well cushioned but with widths that may require more leg curl and make it difficult to reach the ground comfortably. The greater the width, the greater the curve that our legs must make to reach the ground and therefore, we will lose height and we will arrive worse.
Touring motorcycles, such as the
BMW R 1200 RT
or the Yamaha FJR 1300, are designed to offer great riding comfort for both rider and passenger. The seats are generous and comfortable and being wider can complicate access to the ground depending on our height. For this reason, they are not particularly high so as not to complicate maneuverability, as these are generally heavy motorcycles.
Trail bikes, such as the BMW 1250 GS, the KTM 1290 Adventure, the YAMAHA Superteneré and the
Honda Africa Twin
are those with very high seats. As motorcycles intended to provide good performance both on and off-road, they require high ground clearance. Therefore, its seats are high, over 820 mm, with the confidence problems that this entails for all types of bikers, whether short or tall.
The offroad motorcycles or off-road motorcycles, such as the
or the HONDA CFR 250R or the
like the enduro or motocross bikes, as well as the supermotards, are bikes with very long suspensions, high ground clearance and, therefore, high seat heights. They are designed to ride almost always standing up and the seat should not be far away, but as their suspensions are soft, even if the height is even more than 900 mm, it lowers a lot when the rider sits down.
The height and width of the seat determine the comfort and safety of the driver as they influence the ease with which we reach the ground and can have a stable and safe position.
Putting both feet on the ground is not the same as reaching the ground with only one foot, and if we also consider the weight of the bike, these are factors that usually influence the choice of the bike. However, with
these factors are no longer such a serious problem, since the length of the rider’s legs is increased by up to 4 cm, reaching the ground better, which improves safety and comfort.
avoids having to apply the traditional solutions of modifying the seats, the height of the bike or the suspension settings, solutions that can all lead to safety and comfort problems for the rider.
