This is a gadget to hold your motorcycle front brake lever from the throttle handle bar to make sure the bike doesn't roll away while parking on a hill. This size is specific to my 2016 Zero DSR electric motorcycle and brake settings, so please measure the throttle diameter and the distance between the far side of the throttle to the brake lever to ensure proper function on your bike before printing. The latter measurement was about 80 mm for my bike.

There are two versions: one with a helmet strap hook to hang your helmet and one without. The ring is intended as a handle so you can flex it over the brake lever, pull it back and then flex it over the throttle.

The usual caveats apply: Use at your own risk. Make sure to only use this when the motorcycle is off or the kill switch is enabled to avoid the motorcycle taking off. Remember this only locks your front brake.

I found 30% infill was sufficiently strong and still flexible enough to bend over the throttle.
