Crankshaft position sensor
« on: July 23, 2026, 06:26:25 PM »
My first post so here goes. I am trying to install a digital gear indicator on my 2008 Griso, one of the wires has to be spliced into the crankshaft position sensor also known as the pick-up coil, problem is I haven't been able to locate the sensor. the other wire has to be spliced into the speed sensor which I have located at the rear wheel and has a connector behind the right-hand side cover. Ideally, I would like to connect these two wires up closer to the instrument cluster. I am hoping somebody on this forum can help me locate the crankshaft position sensor, and also which wires at the rear of the instrument panel relate to the tacho signal from the CPS and speed signal from the speed sensor. Thanks in advance  :smiley:

The ignition runs off a cam sensor, no crank sensor. Cam sensor is on L/H side on front cover in front of L/H cylinder and to the left of oil pressure sender. Good Luck

Thanks for your response, now I am confused I have enclosed pictures of what I think you are referring to, the one on the right (circled in red) has 3 wires going into it and I have traced them back to a connector up under the head stem area (second photo). However, the one on the left with Moto Guzzi stamped on it has no wires going to it. If the one on the right is the cam sensor and not the one on the left which has no wires connected to it, does that send a pulse signal to the tachometer?  :grin:

Please don’t blow something up fitting something to tell you what gear you’re in.
I know it’s your choice, but…..Honestly ?
But yes, good first post and welcome.

Top picture is the cam sensor. I don't know what wire. The tach is independant & works off ECU pulse

The Suzuki V-strom I recently rode across country and back with had a digital gear indicator. I loved it. Super useful. If you haven't ridden with one you'd be surprised.

BMW K100RS I owned had one. It was cute.
No other bike I owned was so equipped.
If you ride regularly you know what gear you are in by engine sounds.
First was always at the bottom.
That was enough information.
Given the choice I'd opt for fuel gage over gear position indicator.
But trip meter (or a good reserve) eliminates need for that.
So simplest is best.
Ural has speedo & trip meter.
It's gotten me from Canada to Florida with no more.
Simple is good.

The '26 V7's come with a gear indicator. It works even with the clutch lever pulled. I like knowing which gear I am in, not a necessity but nice and handy at times.

I have the Gear indicator on the V85 and on the V7 Stornello running the MGMP module and app. It's nice,  but on a machine as pure as the GRiSO, with no traction control, no ABS, no throttle body wire, no cruise and no other electronic gizmos, it just seems out of place. I don't have a GPS or RAM mount for devices or even run TPMS on it. Is the most pure modern motorcycle I own, and I love it that way.

It would be fine on the Norge though. Look forward to seeing your outcome. Great First post and welcome!

I have 5 bikes with 4 totally different feels when riding. The only time I know what gear I'm in is on the highway in 5th or 6th.Some times I'm not sure then. I've found my self shifting down looking for the big green N so I can go to the gear I want.  If I don't have time< I gently let the clutch out and shift up or down according to what the engine does. It would be a hell of a lot easier with a gear indicator light. It's technology from before 1980 as I had a gear indicator on my 1980 GS850 (plus self cancelling turn signals, plus a gas gauge, plus a fuel reservoir valve). Those Suzuki guys were on top of things. Very easy to do from the factory. I'd rather have a gear indicator than 5-6 plus a custom made ride moods.

I don't think the original poster ask who all would like one but ask a simple tech question. There isn't a tech section here, so everybody was asked.

Maybe you should just spend some time getting to know your new Griso before making any mods.. I get where you’re coming from tho. I like modding my things.

If you don't know what gear you are in, maybe you are paying too much time on the wrong things while riding.

Yes and the instrument cluster was the same one as on the 1000 and you could see the "6" that never actually illuminated on the 850.  It was kind of mean.

Anyway I am in the camp that appreciates a GPI, and the real one on my V85 is a LOT nicer than the "I will try to calculate it when conditions permit" version on my V7.  I also love the real fuel gauge, even if it is far too pessimistic.  Now if only the speedometer didn't read 7% over, with no way to correct it. 

Riding shouldn't be about making best guesses and constant mental calculations, when the correct info can easily just be provided.

You can get the speedo to read accurately if you go into the map & change a number. I did this on a few CARC bikes to read dead-on.

My '68 Triumph 500 had a mechanical pointer on top of the gearbox.  Only 4 speeds though, so ya really didn't have to look down at it very often!  :shocked:

More thread drift.

The self cancelling turn signals worked both when moving and stayed on while setting at a light (not on a timer). I didn't appreciate that feature back then. As the saying goes, more information wasted on the youth.

I hadn't heard that for the V85TT. I wonder if that's true on it.
