Choose the z-Start if you place a high value on any of the following features:
- "Stock-like" clutch lever feel
- 100% override of clutch engagement at any RPM
- Ease of installation
- Reduced maintenance
- Improved Durability
If the clutch lever feel is not as important to you and you can manage a little more technical installation, the z-Start is a great value and proven performer that has been installed, maintained and used by thousands of riders all over the world.
