Title: Throttle Lock
Post by: BrianTRice on September 13, 2016, 08:58:33 AM

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 (http://advrider.com/index.php?threads/atlas-throttle-lock-a-universal-motorcycle-cruise-control.1014518/) shows some practical photos and discussion.

The Atlas throttle lock (http://www.atlasthrottlelock.com/) seems to suit the Magura throttle (http://www.evdrives.com/product_p/thr-magura-assy.htm) 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 (http://www.atlasthrottlelock.com/pages/throttle-lock-comparison-chart) illustrating how different throttle lock mechanism approaches have tradeoffs, to which I'll add my experience:
I've documented these findings on the Zero wiki manual (http://zeromanual.com/index.php/Common_Modifications#Throttle_Lock).

Many motorcycle owners have used a rubber O-ring installed between the end of the throttle and the bar end weight to provide tension on the throttle so as to act as a sort of throttle "locker". 

Many years ago I used an old piece of wire coat hanger, wrapped around the throttle grip in a loop, open to the front with the ends of the wire extending above and below the brake lever.  Tension on the wire loop was provided by a rubber band, which could be adjusted by bending the ends of the wire and/or increasing the rubber band tension.   ;)

Those are good cheap solutions. Of course, a Zero needs a bar end in the first place...

I've been trying this in my 85 mile per day commute, and I have to say this performs really well, and more or less solves touring ergonomics for the throttle. It's basically the game-changer for the throttle.

Side effects / issues:
I'll take photos once I've figured out the ergonomics for sure, to illustrate a good angle I found and why, and show how I use a Crampbuster in concert with it. Right now, it's pretty close but I'm trying to decide whether another tweak would make a significant difference.

I wish I'd figured this out earlier this year - I would have ordered one of these to deliver to Ben to help him out with his trip, but at least we found a Crampbuster for him to have/use.

Okay, here are photos now that I'm basically satisfied:

This continues to be really great for highway cruising. A little practice makes it very easy to lock and unlock the throttle quickly. I even adjust the crampbuster so that my hand can rest with my thumb on the button easily.

I'll state the obvious advice: only use this on boring highway stretches with good visibility and no traffic crowding.
