I was thinking about some improvements I could share with you that had really enhanced my riding experience. One that came to mind was replacing the thumb throttle. While my wife and oldest son prefer to utilize a twist. Not one of my favorites. My youngest son and myself use a trigger off a jet ski. It was an improvement that allowed me an extra couple of hours ride time because my thumb wasnt cramping or just wore out. My youngest had trouble completing races until we installed one on his bike. Some do not like it. I personally feel more in control being able to actually lock both thumbs around my grips. It also gives the option of using different fingers or all your fingers without the danger of whiskey throttle. Hope this is helpful.
