Post Zuma/BWS 125’s Digital Speedometer Available for Older Model
We’ve all been loving the BWS X speedometer. It’s got a smaller footprint, a nice and simple screen that shows all of the functions that the standard/stock speedometer doesn’t. Koso/PGO even came out with a clone for awhile with some friendlier attachments. However, they also only came out in Kilometers per hour; no MPH.

Starting in 2015, Yamaha came out with the newer Zuma 125s with a digital speedometer that is very similar to the BWS X style speedometer, and this one comes in MPH (and could be altered to km/h for our metric friends). Below is a link to a YouTube video that shows off what that nice digital speedometer looks and acts like.

So my question is; can this part be ordered and installed on the older Zuma/BWS 125s? Has anyone done this? Thanks.

That would be a really cool mod if it could be done simply

I took this question to a local scooter shop here near Portland, the scooter turd shop. One of the guys there was very much interested in the thought of simply buying the part and trading it up. He looked up the speedometer part for a 2016 Yamaha Zuma 125 from the Yamaha Parts House web site.

https://www.yamahapartshouse.com/oemparts/a/yam/56e0907187a8660718f20e4c/meter

Then he looked at the section for the front wheel.

https://www.yamahapartshouse.com/oemparts/a/yam/56e0904c87a8660718f20dc2/front-wheel

He found that the newer Zuma 125s speedometer cable attaches to the sensor on left side of the front wheel, while the older Zumas attach to slightly different sensor located on the right side of the front wheel. He wasn’t sure how that would work.

Since I’m still a new owner, I don’t want to just jump into this expense just yet. Maybe in a few years I’ll check this out. If there’s anybody out there who is braver and richer to try this, I would love to hear from you. Thanks.

Hello NATE6194,

Sorry about the late response. No one else has responded to this, so I’ll need to give you the little that I’ve found. The BWS X speedometer is not made for the US market and only comes in Kilometers per Hour. There used to be a third-party clone that was made that doesn’t have the Yamaha logo on it. I believe that it too didn’t offer MPH.

Zuma Forums own ZUMIKE has a video on YouTube (as Mike’s Bytes) that shows the BWS X speedometer in action.

https://www.youtube.com/watch?v=UV-0SrtnpDY

Starting with the new Zuma 2016s, they have a different speedometer with the lights on the right side versus on the left like the old BWS X speedometers. Look at the videos above. This would be totally cool since it can be shown in MPH. It would be great if it worked.

As far as other digital speedometers, Koso, Polini, Stage6 and Trailtech make various kinds. The local scooter shop that I go to has a bunch of them that you might be able to order from. Here’s a link to their Zuma 125 parts area of their web site.

Best of luck in your search.

Rudge, I can look into trying this swap in a month or two, after I get my motor installed and my mono shock setup fabricated. I currently run the PGO digital cluster from Chris @ Race Concepts. My suggestion until then is to see if Race Cencepts (Chris Cey) on facebook knows if it's compatible or not. I will message him to find out and post a reply here if I get info. If no info is available, then I will see about purchasing and testing compatibility of the part myself... again it might be a few months before I can get to doing that.

According to Chris at Race Concepts... "as for newer zuma gauge to work on older version it needs a adapter cuz even the ecu is different and wire harness totally different the whole fuel injection system and o2 sensor and throttle body sensors is different and not interchangable with older version." Basically, to make it work, you will need to rewire the entire wire harness on the gauge to either your stock gauge's connectors, or wait for some sort of wire harness adapter to make it compatible.

Even still, there may be some unintended side effects... like a fuel level that's not accurate, or a Tach that is not accurate or the reading may fluctuate randomly. It is a difficult troubleshooting task which will require some close review and comparison of wire diagrams for both models.

If there are some sensor signals that are not compatible due to the difference in the ECUs that process and output those signals, there might be a need to adjust or scale the voltages or resistance values by tapping into the affected wires and splicing in an appropriate signal conversion circuit (this is the unknown and difficult aspect of trying this swap). I recommend just waiting for an Aftermarket harness adapter for the new gauge cluster or buying an aftermarket gauge like the PGO.

On a positive note, I found out that my PGO digital gauge may still have a functioning Tach... i also have a Hoedar ECU, which may have caused the Tach issue I have and requires a wire splice and connector pin swap to fix it. The PGO gauge is a good option and offers both KPH and MPH options.

Thank you, JohnnyFYX for your posts and for contacting Chris Cey on this subject. I sort of suspected that this new OEM gauge would be
incompatible with the older Zuma125’s. I knew that there would be some gyrations getting the tachometer hooked up, but didn't count on
the other headaches. Such a nice simple-looking gauge though. What a shame.

Also, it’s a shame that the BWS X style digital gauges and it’s clone can’t be changed to read in MPHs. If someone had made that change,
they would have gotten rich by people here in the States.

DynamoUSA has a YouTube video that shows the PGO digital gauge in action and offers a wiring/installation procedure. It looks kind of complicated.

Thanks again.
