Having serious problems finding a Mito 125 speedo drive for my LC. I have Aprilia RS125 clocks (also cable driven). Is it possible to make this digital in some way?

you can fit a GPS speedo, or a cheap bicycle digital, but converting your original isnt possible I fear, if you do find a way, let me know I need to do that on my XT500.

Kinda what I feared Jon. I can get a speedo drive from Germany but the prices and postage are truly insane. The hunt continues but if I find a solution I'll let you know matey.

You can run and R1 speed sensor of the front sprocket on the bike, you need to make a bracket to hold it in place and I beleive you need a speedo healer to make it all work. Ill look for the info on how to make it work,

Yep you can do that, but not with the RS clock the OP wants to use.
I have a full R1 setup I was going to sell as Ive never used it. Its a nice setup, but its a convoluted setup by the time you found and fitted the tacho and speedo 'healing' units and got working dash, sensors and wiring etc These days R1 parts for the 98-01 bikes are expensive as the bikes themselves are now worth good money as Classics, the R1 dash thing is a slice of the past really, kinda like RGV suspension on our bikes, its just too much money to source now. :/
Donkey, you could drive the speedo off the rear wheel of course.... some bikes do that. Else is there another unit, like say a KTM, that might fit. I doubt the Ape unit is a dedicated part, they didnt sell that many units so surely its shared?

I spoke to digital speedos at the kit car show regarding a bike Speedo assy.
He showed me an electronic adaptor that screws into the Speedo drive and outputs pulses. Nice and neat, but if you don't use programmable clocks, you may need a Speedo healer.

Yep Ive looked at those as well, often theyre too bulky for our use, its a nice system to avoid the pickup off the sprocket or gearbox teeth, and sadly the ones Ive seen are not cheap either. this is my GPS unit:   my write up on fitting it is here: (bottom of the page) www.2smoked.com/Yamaha_RD350_LC_421cc_Athena_Frame.htmlThere are a nice set of GPS units now with needles if you dont like digital, have a check on ebay. |

Alex I have an rs125 front end in the garage, pretty sure it'll have the speedo drive on it, I'll root it out this week if you still want it? wang |

Not sure this is relevant to anybody but I will share anyway
I have a fazer 600 front end for a build I'm gathering parts for and the front wheel looks like it uses a traditional Speedo drive as I have used an rd400/sr500 drive to cable drive a standard Speedo.
The fazer 600 uses an electronically driven Speedo but appears to use a standard Speedo drive but has a cable with what is surely a pulse signal
Should be possible then to drive an electronic Speedo off a traditional style drive

If you have one Wang that would be brilliant. I'm using Mito forks but I think they are the same as on the RS.

I might be able to use something like that... I only realised it was different when I was searching for a "drive" on eBay and none came up Changed it to sensor and things like this came up www.ebay.co.uk/itm/1998-2004-Yamaha-FZS-600-FAZER-speedo-drive-sensor/113754836093?hash=item1a7c510c7d:g:nR4AAOSwKHtc4Wq3Steve |

Thanks Steve, it'f be interesting to see what pulses those produce, but i suspect one pulse per revolution. That would work fine on the original series of clocks, but not for the gearbox sensor driven units like the R1 cluster which demand a lot more pulses. Also worth noting that not all Speedo Healers are created equal; some can only multiply the pulse so much, so if they can only say do 10x the pulses of a single wheel turn then the R1 clock would never register much speed as the clock is used to getting a feed from a many toothed (60T?) gear.
What it does mean is that something like using the whole dash might be a goer, you'd only need the OEM temo sender and a rev counter healer (perhaps just a simple 'doubler'). Of course you might well blow up the tacho working out if the ypvs voltage can drive it etc. The downside is that splitting the Fazer clocks isnt really possible as while they look seperate they are a single circuit board, perhaps yam fitted the same speedo drive to other bikes... I might well do some research on this, could be interesting, cheers for the heads up!
EDITIED: Been looking and that speedo drive seems only to have been fitted to the Fazer6, nothing else. not saying there isnt another bike that has something similar but that part number is that bike only. I also dont know if the clocks are stand alone like the early R1s, ie you can isolate it from the CDI or if the info going to the tacho/speedo comes thru some kind of black box like the later R6/R1 etc.
Sorry Donkey for taking this a bit OT mate... good info tho I hope for others.
