X-cruise are Throttle locks, sort of a cruise control for mounting on your throttle. Designed to sit on the far left of the handle with built-in anti-blocking of the throttle. X-cruise are made in two variants.
Mounting the X-cruise is very simple and a 2 minute job, almost without tools.
You don’t even have to unmount Handguards or bar end mirrors as you can twist the adapter ring and X-cruise arm round their brackets.
