PostSubject: Motodemic Fitment Woes   Motodemic Fitment Woes Icon_minitime1Fri Aug 06, 2021 10:52 am

We recently had a customer call in and they referenced a thread on this forum that mentioned someone having slight fitment issues. After doing some searching on the forum and comparing previous customer interactions, there seem to be mixed experiences using a product we originally made for the V7 family but should fit the GRiSO without issue.

When we developed the kit for the V7, we bought a V7 light and utilized an off-the-shelf housing that was slightly smaller. Then we designed adapters to make it the exact same width and have m8 threads. Couple that with a wiring harness with the same OEM connector and premium LED unit, we have an excellent drop-in replacement for the Guzzi Gang.

Once we finished the product, we did some part number cross-referencing and found that Guzzi used this headlight across many models over the years, which seems to only be on paper. We later found that part number is being listed as a replacement option for part numbers they are no longer make the originals of. Yay, that makes things super straightforward... not.

What we do know is that people have different definitions of "good fitment". To me, good fitment is something that drops in perfectly and does not require extra work. No bending or flexing in order for it to assemble. We also know that when we bought the OEM listed headlight for a GRiSO, the headlight that came was the same size as the V7 unit but in chrome. It also had the same connector and wire locations.

We have been trying to get a GRiSO in front of us on and off over the years but it just hasn't happened. We are hoping to get your feedback if you have purchased our housing (either from us or from JW Speaker Retailer) and make any needed GRiSO specific adjustments.

Our adapted housing measures 186mm across the mounting points. If you've had fitment issues, what is the measurement between the inside of your stock headlight supports? Maybe the stock headlight supports have tolerance and just need to be loosened, adjusted outwards, then tightened. That is the only thing that I can think of as to why some fit fine and some do not.

Are there any GRiSO deep knowledge peeps on here that may know if there was a slight change in the model along the way?

Any help here would be awesome and I will think of something to show my gratitude if we can get to the bottom of it.

- Brad

2014 GRiSO 1200 SE.  Had interference at the mounting points. Would not fit into the frame/basket with any amount of hand-pressure.  I lacked the ingenuity to McGyver a strap or some other contraption to pull it in, but I recall someone on this forum did just that.  Unfortunately, I had to opt for some carefully applied dead blows  [You must be registered and logged in to see this image.] to the mounting points on the bucket.  I can't recall whether the threaded fitting was proud of the bucket surface?  At any rate, with great care and patience I was able to gain sufficient additional clearance without distorting, creasing or otherwise marring the bucket.  
I did not record my measurement and am disinclined to disassemble because there's a fiddly windscreen mount in the way.  If there is variability in the OEM mounting points, I would've preferred to shim @ the mounting points rather than trying to 'create' clearance.

I'll add- I ran into a rats nest of wiring from past ownership attributed to a shop in California, Motodemic was very responsive to my requests for guidance on that front and I appreciated that. [You must be registered and logged in to see this image.]

FWIW, here is another thread on the topic that is current at time of posting: [You must be registered and logged in to see this link.]

I don't believe there have been any changes to the frames that hold the headlight that would affect fitment over the years. I've recently replaced the assemblies, (The frame that holds the lamp bucket is a two part affair.) on the written off shitter I'm resurrecting and because one of the frames was quite bent I purchased a second hand pair from a different year model and they were, as expected, identical dimensionally. I also believe that the part numbers for the frames haven't changed over the years.

I did have to McGyver the instrument mount at the top of the frame but that was due to a stripped thread rather than any physical difference to the parts.

Dropping the headlight bucket, (Which as you will of seen is a truly cheap and horrid piece of shit.) is no big deal so I can easily nip up to the shop over the next couple of days, pull the light out, take a couple of photos and measure the width of the mounts if you would like?

I'm sure we've got some GRiSO owners/ghetto members in the East Bay/Stockton area who cold get a GRiSO over to you for an inspection/fitment test.

Any volunteers giving this thread a look?

@SMTCapeCod - Your post may be the one that the customer was referring to. My thinking is that variance is in where those mounting points attach to your bike. From the parts diagram, they attach at the top and bottom to the triple clamps and almost look as if they can pivot in and out (similar to how the V7's are). Completely agree a shim of some sort would have been easier.

@Pete Roper - Your info matches what I have found. And I agree on the quality of the stock lamp.

@Steak - That would be amazing and we would make it worth their while as well.

I think a search of this forum and one of the other Guzzi forums would turn up a few different instances of similar concern.  Let me just do a little desktop research/development for you:

I'll post the schematic.  A shim at the mounting points might do it if it doesn't throw other dimensions too far out.

The problem is the bottoms of the frames bolt to the lower yoke and that spacing can't be shimmed sideways. They are fairly substantial chunks of alloy, (Not much on the GRiSO is lightweight! Laughing apart from shit like the headlight bucket!) and won't take kindly to bending.

@SMTCapeCod - Thanks for the help! I've definitely done a lot of digging and read any post on this site that has the word "motodemic" in it. I'm going to try ordering another #1 from that schematic. We ordered it in the past and sent it back when it showed up the same size as the v7 unit we have. If it's only 1mm difference we can just make new adapters for the housing we are using now. Hoping I can get a bike in front of us so we can be 100%.

Where we've gotten conflicting info is direct customers and others that have purchased through the JW Speaker channels and didn't mention having an issue installing. Such as Cantaloop and Lehctim in this thread - [You must be registered and logged in to see this link.]

Both are using our housings/full setup.

@Pete Roper I see exactly what you are talking about.

The width of the mounts is 185mm (V7 must be the same as it's same shell)
& as Pete says the mounting 'brackets' are super rigid & solid bolted to non-adjustable points on bottom on the fork yolks & at top so you can't create any extra gap....as a result it can be hard to squeeze anything that's even slightly bigger (especially if it's rigid as well - OEM shells are easy to deform); they are also shaped so any shell has to be at least similar or smaller profile around the mounting points and to rear.

My GRiSO is a 2011 8V 1200 (A8 engine).
I had ordered the headlight bucket July 23 in Germany via [You must be registered and logged in to see this link.]
Just mounted it without problems - okay it was very tight but it works.
The build quality of the bucket (https://motodemic.com/shop/moto-guzzi-byol-headlight-upgrade/) is very good.
The price in the US is reasonable, for Europe it is expensive (approx. 170 Euro) which might be caused by shipping and customs.

Update:
The bucket fits when headlight is not mounted:
[You must be registered and logged in to see this image.] [You must be registered and logged in to see this image.]
but it is really very tight.

Unfortunately is does not fit anymore when the LED unit is mounted but you can solve this problem by loosening the upper and lower screws of the bracket holders.
[You must be registered and logged in to see this image.] [You must be registered and logged in to see this image.]
and tighten them after you have mounted the complete headlight.

I bought your headlight shell last fall 2020. Its just 1 mm too wide resulting in paint damage on the mounting bracket as I had to force the headlight in. See attached pictures. For the price (EU so also import and shipping) it was honestly a little disappointing.
The distance between the mounting points on my GRiSO is 185mm

I painted the damage and remounted the headlight today the same way you suggested in your video and that worked perfectly  [You must be registered and logged in to see this image.]

So it seems like either using janguzzi's method or a housing that is 1mm smaller in with would solve this fitment discrepancy.

Thanks a ton for the feedback here and I will work on getting the product updated for future GRiSO peeps.

FYI - We do sell this as a complete kit with motorcycle-specific lights. Arrives assembled and ready to install [You must be registered and logged in to see this link.]

Hallo Brad,
glad you came back here.

The headlights options you offer together with the bucket were not the ones I was looking for.
I was looking for a headlight with the best possible visibility and an almost classic look (chrome).
So the the 8700 EVO 2 PRO (Chrome) was the best option for me.
The biggest issue I had was to find the perfect positions for the spring clips.

Is the dipped beam pattern adjustable?  To allow for change to driving on left or right… eg. UK to Europe, or does its dipped beam have a neutral position?

ps. so I can work out import costs, what are your shipping costs to the UK?

We use a motorcycle specific reg113 symmetrical beam pattern so the lights are legal for both directions of travel.

The best way to get a total price is to add your items to the cart and use the shipping calculator to see time vs cost.
