Title: Throttle replacement for SR
Post by: Kill3rT0fu on October 10, 2021, 03:17:43 AM
So I took a spill and the throttle and grip got a little messed up. yadda yadda yadda, it needs replaced. Is this something the dealer has to replace or can I do it?
I already have the parts I need in my cart on AF1 racing, but before I pull the trigger on a $200 part I'd like to know if i'm wasting my time. I don't know if it's plug and play, or if the dealer will need to do any weird calibrations with the controller.

It may seem like a simple question, but I'm learing there's a lot to these bikes that aren't end-user friendly (Like the New Zeroland channel has discussed)

Well, what harm is there n getting the parts?

There's no note of such a problem in the unofficial manual.

I just dont want to be "that guy" who rolls into a dealership with my own parts and say "put them on". I know mechanics usually hate that. Like walking into a restaraunt with my own food saying "cook this".

Also, does zero use a custom throtttle now? Or are they stil magura?

That's silly.  You didn't buy the bike from them.  You're paying for the time to fix something.  You'r not asking them to use parts that are abnormal or out of their ability.

I believe the Zero SR throttle replacement is plug and play.    There is a gray plug behind the headlight that the throttle plugs into.   You do need to remove the dash, electronic display and headlight to get proper access.   There is no mention in the parts lists of any programming necessary.  All 2015 and up Zeros seem to use the same part too; 45-08039.

A word of warning if you are going to do the swap yourself.  Today I swapped the handlebars on my SR to those found on the DS/FX model.   When I removed the throttle, I unscrewed the Torx Security screws (T25 with the hole in the center) completely.   This was a mistake on my part.   It allowed the throttle to "disassemble" itself.   The inner spring unwound.  And the entire throttle came apart.  I even dropped a part of the position sensor on the floor and didn't notice it missing.  So my throttle didn't work until I found the part and reassembled it properly.   So if you do the swap, only unscrew the Torx Security screws enough to allow the positioning pin to come out of the hole in the handlebar.  Otherwise you will have to learn how to assemble an electronic throttle.

^^ 100% on only backing the T25 bolts off enough to give clearance for the locating pin.

Made a video a while ago showing the process of putting everything back together.

Think the torque call out for the T25 bolts is 5Nm, if you over torque them the housing may crack.

LOL.  Where were you yesterday?   Great video.   Glad I don't have heated grips so I don't have to deal with one more cable.

Aw crap really? This bike is getting stripped naked then. Might take this opportunity to swap headlight assemblies with a KTM or something of similar shape.

Do you happen to know what sockets and tools are required?

If you don't have a windscreen like I do on my SR, then you probably only need a set of metric allen wrenches.   I think there are 6 of the small black ones around the plastic trim and 2 large ones that actually hold the headlight in place.   The only thing that I don't know is how the stock signals attach to the bike.   My SR has a set of aftermarket LED turn signals.

And as I mentioned earlier, you need a T25 Torx security bit.

Does the throttle come with the grip? If not, are there any tricks you used to get it on? I remember having to get one off a 1998 CBR and it was almost impossibly tight. I don't wish to do this on my zero

I would imagine grips are sold separately.  At least you can buy them that way.   The new grips that I've purchased from AF1 don't say ZERO on them either.    So you might want to buy both sides you can't remove the old one or if it was damaged in your fall.  They are $10 each I believe.

Is the bar for the throttle slightly shorter?  I had to cut a bit off the grip I put on mine.

What part did you cut? Do you have any pictures? Why woulda replacement be different than what shipped from the factory?
Here's a pic I found on a domino thread:

Top is magura, bottom is domino

are the zero magura throttles the same as the plain ones you get from EVdrives.com or electricmotorsport? They're twice the price.

I cut off the flange so it wouldn't rub the housing.  I could have cut off the end instead, I suppose.  The Atlas throttle lock I got was upside down compared to the phlange on the throttle, too.  So I couldn't use it.

Ok so I'm starting to put the parts on the bike and I'm a little freaked out. I cut the wires that were coming from the throttle and there's like 8 different wires in there. Yellow, black, white, blue, green, etc....

what are all these? Did I cut the wrong bundle of wires?

-edit-
Apparently it's a Bitron throttle? https://zeromanual.com/wiki/Bitron_Throttle
And I guess you're not able to swap throttles because of the hall efect thingies? Unless you guys know of a way to connect everything.

A replacement throttle should be plug and play using the supplied connector.
I take it your SR was built before 2015 and uses the old style 3 wire throttle?

:( sorry

opposite. It's a 2021 model and has 8 wire connectors. The domino throttle is the part with 3 wires I'm trying to connect, but I guess they're not compatible. So I just ordered an OEm throttle

Does the handlebar need greased for the OEm throttle? I'm putting the new parts on the bike and I noticed the throttle area has a white grease. I'm not sure if that leaked from another part in the accident, or seeped out of the throttle housing,

When I replaced the handlebars on my 2018 SR, I don't recall there being any grease between the throttle and bar.   Seems to me putting grease there would only act to attract and retain dust and dirt.

There's a thin layer on mine. Not a ton. I wonder if it leaked out from somewhere. But thanks for the feedback. Almost done buttoning it up now, this one question was holding me up


HOLY FREAKIN COW THAT SPRING IS A PAIN TO GET BACK IN!!!!!!!!!!!!!!!!!!!!!!!!

Yeah this thread was mostly started out of a lack of information and ignorance on my part, the main fact being the domino throttle (which a few people claimed it works) DOESN'T work on NEWER models of the S platform. Just stick with OEM. Prepare for battle with the spring. And everything should work out.

A bit late but, that white grease.  Lithium grease? or if there are any electronic parts in that thingie, some heat sink / heat transfer paste?  Sometimes it can be applied like that, under stuff to help keep water out, humidity hanging out etc type application, which could eventually cause issues.
