Universal Vista Cruise Control

Also known as ‘cruise controls’. We sell simpler ones which actuate ‘on-off’ ergonomically and easily, and which separate on-off function from adjusting applied frictional resistance. For less wrist fatigue you want to be able to micro-adjust the precise amount frictional resistance so only just enough is applied to hold engine speed steady, and nothing more.

Easiest types to install simply clamp over the twist grip and rest against the top of the front brake lever. These must be continually reset each time you open the throttle a little father, which is fine for most situations, but better solutions are the permanently installed types.

There are three general styles of this type: ‘Bar-end’ locks, ‘Thumb-lever’ locks and ‘Throttle-housing’ (screw-in) locks. And there are two versions of each style: Types which separate on-off function from frictional force applied, and those which don’t.

INSTALLING AND ADAPTING

Bar-end types are bolt-on replacements for bar-end-weights. A few separate adjusting frictional resistance from on-off function. Those that don’t are less ergonomically convenient because they require multiple rotational motions with the heel of your hand to incrementally screw them on or off.

Screw-in types sometimes require tapping a threaded hole in a throttle housing in exactly the right place, but many older BMWs and Harley Davidsons already have this and all one needs to do is remove a plug and screw in the correct part.

Flip-lever types sometimes bolt-on simply, but many applications require a little improvising and adapting. Thumb lever-actuation is ergonomically easiest for most riders to manipulate. Filing and drilling their plastic parts where needed is usually simple, and is done either to hold one side of the clamp stationary, or to radius the inner frictional surface to exactly match the diameter of the throttle housing.

CAUTION AND WARNING

For safety, throttles must self-return to idle. Throttle locks defeat this important feature. Although we have never learned of anyone who’s experienced safety-related problems with these locks, it’s still possible. If you are not confident about working with and adjusting these kinds of mechanical devices, find someone competent to help you. After the lock has been installed, and before your first ride, be absolutely certain that whenever the lock is disengaged or ‘off,’ your bike's throttle returns to idle the instant you take your hand off the twist grip.
