2017 Harley-Davidson 1200 Custom There s a comfortable seat. A ground-devouring suspension. Putting 1200cc of H-D low-end torque to the pavement never felt better. We named it Custom for a reason. The heritage of the Sportster runs strong in the 1200 Custom. The 1200cc Evolution engine pounds out the low-end torque that made the Sportster famous. Pull back buckhorn bars; steel laced wheels and a fat front tire add to the classic look. And features like an adjustable rear suspension; powerful brakes and a comfortable seat bring it all into the modern day.
