The bike comes with a host of advanced features such as adjustable suspension, traction control, assist and slipper clutch, and LED headlights.

It is a great choice for new riders and city riders who want a daily rider for work or commuting.

When comparing the two motorcycles, the Z900 stands out as the better bike in many ways. It has more advanced features, better performance, and offers a more refined riding experience.
