The Sachs XTC S with a seat height of 800 mm may be too tall for a rider with a height of 165 cm. Generally, a seat height that is too tall for a rider's height can make it difficult to reach the ground with both feet, which can affect stability and confidence while riding. It's important for a rider to be able to comfortably reach the ground with both feet while sitting on the motorcycle, so a lower seat height may be more suitable for someone with a height of 165 cm. **

A loud shock wave can be generated by a sudden release of energy, such as an explosion or a supersonic object breaking the sound barrier. Explosions create shock waves by rapidly releasing a large amount of energy in a confined space, causing a rapid increase in pressure and temperature that propagates as a wave. Similarly, when an object travels faster than the speed of sound, it creates a shock wave as it pushes through the air, resulting in a sudden and intense pressure wave. Both of these methods result in the generation of a loud shock wave that can be felt and heard. **

It is not recommended to mix different sizes of tires on the same axle. The 165/60R15 and 165/65R15 tires have different overall diameters and rolling circumferences, which can affect the handling, stability, and traction of the vehicle. It is best to use tires of the same size and type on all four wheels to ensure optimal performance and safety. **

Shock wave therapy is used for patellar tendinopathy by delivering high-energy acoustic waves to the affected area. These waves help to stimulate the body's natural healing process and promote the growth of new blood vessels, which can improve blood flow and promote tissue regeneration. This can help to reduce pain and inflammation associated with patellar tendinopathy and promote the healing of the damaged tendon. Shock wave therapy is often used in combination with other treatments such as physical therapy and rest to effectively manage patellar tendinopathy. **
