Demetrios, do you have a link to the spacer?


October - I didn't use the T tab plate, just the Honda plate with the stuff ground off. But as I said this is a CNC'd basket so probably doesn't flex as much as the pressed ones.

Demitrios. That's the whole idea of the BGM modified plates.

They fit like standard clutch plates according to your specific clutch basket.

Fit and forget

Thanks Ginch...

You always hear people saying you need a banded clutch etc...

So of course I get worried.
But the last time I redid my clutch, it was pretty beat, and I had to replace the basket because it was spread... I almost think if it didn't have those T tabs it might have been able to release the clip

But that could be me being paranoid

This is the link.i have an issue with these plates.i use them on a sip cosa sport banded clutch basket,and need a bit more modifiyng compare to other baskets.anyways thats not the issue!the link says that the spacer is 1mm,and we measured the plates and is 1mm thinner compare to the piaggio ones,metal plates included.when i kickstart after a long period of sitting ,the clutch drags,i unscrew a bit the cable adjuster and it starts ok..but on the street it kicks when you release the clutch lever and its not so smooth.so it needs tightenning again!maybe this spacer would solve this problem?anyone used it?

Interesting... the spacer actually reduces the height of the basket? It must also compress the springs slightly more as well. I'd never seen that.

Hi All,
Very glad to have found this amazing post. So my two questions. .....

1. For those of you that have fitted the CR80 clutch rings to a 7 spring clutch, did fit springs that are 50% stiffer as mentioned by freakmoped? or did you run the standard springs?

2. What do you think the max bhp one will be good for using the standard 7 springs? And max bhp with the 50% stiffer springs? Any ideas?

I just used the old stock springs, but on a completely stock P200 motor. I don't know about max HP but reading back in the thread should give you some idea. One thing to note: I found the clutch doesn't lock up as quickly as stock, it slips more for me when starting out. But that's OK, it's easier to ride and doesn't slip at all once it does lock up. This is with only two CR80 corks and the stock T-slotted top plate.

I just used the stock springs. No idea what the plates will handle sorry.

Anyone using the CR80 plates in a SIP Sport clutch or a banded stock Cosa clutch? The SIP Sport basket is not CNC'd but it does have a band welded on and it can accommodate up to 16 springs.

I have the BGM plates that are good for a stock Cosa clutch, so the tabs are the correct width. However they stick out too much to fit within the band. Looks I will need to grind them back. Has anyone done this successfully? I've only seen references to grinding the width of the tabs.

The Sip style Cr80 plates will work in a banded basket, they don't protrude as far out of the basket as the BGM style

I just grind them. I've done many on banded baskets. They work just fine. Just 12EUR for a Honda set. All my friends are happy with the CR plates...

I like that you get the advantage of the thicker cr80 style tabs, better clutch linings and the full standard style friction area, they come supplied with steels as well..
You can leave the grinder in the cupboard

I like that SIP be copyin' Honda, that looks like nice gear.

Chris, this looks like a nice improvement over stock. Is this one DIY?

Yes it's DIY. It was a brand new P/A Cosa clutch and I added the SIP ring and the plates. For some strange reason, the basket was thicker than the stock ones...

Thanks all. I already have the SIP Sport clutch and all it's internals, so I'll grind the BGM CR80 plates to suit. I just didn't want to compromise the performance by shortening the tabs.

Next time I might buy the SIP plates, although the price of the Honda plates is very good compared to what SIP and SCK are charging.

Starting to find the limit with these CR80 plates. My 221 clutch has started slipping. Running on 10 XXL springs. Still ok to ride for now but if I open up to much it slips.
These plates were new earlier this year. Maybe 1500 miles. I am hoping this is why SIP made their own version of the CR80 plates and these last a while longer.

Just rebuilt my SIP Sport clutch with the SIP CR80 plates. They are a perfect fit into the banded basket. No grinding required and they have the same friction material surface area as a regular set of Piaggio cork plates, with of course the thicker and wider aluminum tabs. I've installed with 8 * L springs and 4 * original Piaggio springs. All springs are new.

Let's see how well it copes with an MHR221 motor with [hopefully] 30hp !!

Anyone else have issues fitting SIP rings to cosa baskets? I bought 2; neither fits any of my cosa (Piaggio, taken off actual cosas) baskets, both slide right onto any of my 7 spring baskets. The people I spoke to at sip seemed surprised at first, then told me cosa baskets were 1mm wider than older 7-spring units and hence needed rings to be installed "with violence" (sic). No word on whether they'd pay for damaged baskets if violent methods proved destructive.
I'm planning on cutting a ring to allow it to slide on a cosa basket without deforming it, but it seems like unnecessary added work for something that's supposed to fit from the get-go.

Yeah, they don't fit as they are. I grind them a bit. Don't use "violence" as they said (how stupid are they??). You'll just end up with a deformed basket...

It's a scooter part. Of course it doesn't fit!!

I finally opted for a different solution

Hi all,

I've been following this thread for a while and thanks to the info from mistaFreakMoped and Ginch, I have just fitted a TenInch CNC basket with CR80 plates and spacers to my P200 motor. I used the exising baseplate, gear cog, new standard springs and a SIP reinforce circlip. It just works, feels great, I love it.

I got the parts from Bollag Motos, I would have used Onkel Mikes but had trouble with my delivery address:

https://bollagmotos.ch/?category=kupplungen-und-kupplungsritzel

the site is in German....

If I have any trouble with it I will update here.

A bit late to the party with this one so apologies for dragging up an old topic.

I've just stripped my clutch down in my PX200 after it started slipping when pulling away and discovered the plates had been fitted in the wrong order and the corks are damaged on the tabs. I was a bit worried about the tabs but as I have read this seems to be a regular occurrence so that's put my mind at ease.

Now my question is as I have my clutch apart is it worth me putting the CR80 corks in? I have a standard matt finish set of steels ready to go in and some BGM springs on route. I already have some Cosa Newfren uprated corks to fit but I'd rather upgrade now if it's worth it.

The scoot is standard apart from a SIP Road 2.0 exhaust.

Thanks in advance for any advice 8)

The sip own version of the CR80 plates are better than the Honda ones.

For a 108mm basket though. If you have a BGM/MMW (110mm) basket you can't use them...

Not sure what the OP had, assumed regular. I thought it was only the BGM that was 110mm

Sounds like Wazzzer has a stock Cosa clutch, so SIP CR80s will be the better option. I have them in my SIP Sport and they were straight in, with no mods necessary. I'll only know how good they are when I next pull the clutch apart.

Well, since BGM's clutch is a straight copy of MMW's I assume that both are 110mm. Maybe I'm wrong though...

Stock Cosa clutch is what I have

I'd best get some on order then 8)

just ordered me some and some more cuttng disks.....

2 quick questions, getting ready to order the plates, what years should I be looking at.

and the second, has anyone tried Barnett or any of the higher performance racing plates out there for cr80?

i just ordered a generic set...... id be interested in your findings on the performance plates. construction, thickness, longevity etc

I buy these (CR80, C100N, CBR125, CB250, REBEL 250, etc.)...

These are the inexpensive one i bought to try

if it helps anyone


also when i fit them im going to drill the unused parts of the steels to add more lightness

The Germans prefer EBC plates. They are cheap here in the states.

If I remember when I get home I will look at the box to give you the part number.

EBC 15-1119

I got a set of genuine Honda linings. Still need to file to fit and run, so I cant comment on how they perform just yet.

Right then my CR80 corks have arrived

I have 5 identical corks with friction material on both sides. I'm assuming I just remove one side of the friction material on one of the corks to use as the last one?

Also do I soak these in oil for a few hours as I would a normal set of corks?

Just about to set the grinder up, this should be fun

Yes, only one side for the last one. No, no need to let them soak. Just lube them a bit and put them in...

Brilliant thank you.

Just realised I have a limited amount of grinding tools in my shed so I may have to pop up to my workplace to grab my tools from there

A Dremel with a sanding roll works good. Use something to cover your face because it makes a dusty mess of stuff you wouldn't want to inhale.
