LighTech's dynamic bar end caps are more than just protectors, but weight-calibrated bar end balancers that increase the anti-vibration function as well as protect the ends of those expensive clip-ons. The weight is up to 100 percent heavier than the less sturdy aluminum equivalents used as standard by most motorcycle manufacturers. With reduced vibrations comes improved handling, especially in corners, improved suspension response and reduced fatigue, as well as improved riding enjoyment. Sold as a pair.
