When i had my Hayabusa, i used this company called Tobin Seats in York, Pa... that was my first thought but didnt see any BMW work done there. they lowered my seat and added cool embroidery.
Ill keep looking.
Ok .... found it, pinterest shows the uploader to be "Tapiceria de la moto de Marquez", which means Motorcycle Upholsterer of Marquez, im assuming Marquez is in Spain or its his last name, it does mention Sevilla, and that is in Spain. Many other models too, including Gel seats.
