Although most electric motorcycles don't travel far or long yet, highway travel is in reach and will be more common soon with better chargers and aerodynamics becoming available. I'm used to using some nice cheap options over the years on my Suzuki V-Strom. After trying what I had lying around and reading reviews, my current choice right now for an electric motorcycle throttle is the Atlas, which I've installed along with a Crampbuster hand rest.
The Atlas is a privateer design that went through a Kickstarter phase successfully and now seems to be a side business for the designer. This ADVRider thread
shows some practical photos and discussion.
The Atlas throttle lock
seems to suit the Magura throttle
on my Zero, though it should fit the Domino throttle as well, particularly because it avoids taking up valuable handgrip space and has a generic fitment. The Magura throttle's space for the Atlas to fit into is extremely narrow, though, so you can only use the thinnest friction pad provided.
Atlas nicely posted a comparison chart
illustrating how different throttle lock mechanism approaches have tradeoffs, to which I'll add my experience:
- Kaoko throttle locks operate as bar ends with a dial and are good if the bike fit is confirmed, which no electric motorcycle model has yet. Operating the dial does feel a little awkward since you have to reach for the bar end, but the build is very solid.
- Go Cruise throttle lock is also generic and easy to use but does take up space on the inside of the throttle grip, which makes the throttle harder to use unless you have small hands. On the other hand, it's cheap and extremely easy to install and remove.
I've documented these findings on the Zero wiki manual
