Useful but be careful.
I fitted the Crampbuster CB4 to my Kawasaki VN1600 as I have arthritis and carpal tunnel in both hands. It is easy to fit and works well. I has certainly reduced the amount of grip I apply to the throttle and reduced pain in my joints. One word of warning, on my third ride with it on I needed to quickly reach for my brake and caught it with my wrist. This caused the engine to rev unexpectedly as I encountered a hazard. I am finding the Crampbuster to be useful but remember you have it on the bike at all times.

Hatte schon mal vor 10 Jahren einen 'Crampbuster' als manuellen Tempomat und nutze diesen nun wieder auf meiner Vespa. Da dieser mit einer Kombination aus Reibung/Klemmung am Griff und den Handdruck funktioniert, muss man sich zwar daran gewöhnen, dann funktioniert es aber super und man kann elegant und exakt die Gasöffnung halten. So machen lange Fahrten mit dem Roller noch mehr Spaß
