Marchesini Cush Drive Play Question !

Hey all, tried a quick search but did not see anything, but I thought I remember someone asking about this.

Set of nearly new forged mag 5Y's I think, really low mile, less than 2k I think and a good amount of front to back play in the cush drive rubbers when all mounted up and snug....maybe as much as a 1/2 inch...but somewhere between 1/4 to 1/2 inch...no side to side, just back and forth. Are the Marchesini supplied rubbers weak or inferior? This seems REALLY excessive to me!!

Just to reiterate, these have less than I think 2000 miles use, normal road use also, not racing or anything, and did not notice anything while riding, just on post ride clean and inspection.

FWIW I bought a new set of ten spoke marchesinis two years back the cush rubbers were white and not rubber there was a snug fit to the hub and no lash on install. It's in storage or I'd go check for you.

That is way excessive. There should be no play period. Not sure how things got that way but i'd replace the rubber/silicon grommets immediately.

+1 every set of wheels I have installed or sold were snug with no play even when not mounted to the bike, sounds worn out to me too.

I have a set of Marchesini 10-spoke forged Aluminum wheels.
I believe the cush dampers may be polyurethane.
When new, you have to push the sprocket carrier into the wheel, and there is zero slack.
But after a few hundred miles they take a set and you can rock the carrier just a little back and forth.
I bought my RC51 used and when I first checked them, the carrier had so much slop it would clunk back and forth.
They cost around $72 for a set of 5 with shipping and handling.

Thanks guys...yeah the slop seemed excessive to me, especially considering the running time. Is there a better alternative to the oem Marchesini ones?

Scott will send you a PM!

As i was in the garage today cleaning my chain i noticed the same thing on my Marchesini Al. rear rim. The play is not excessive but it really bothers me that it does that. +1 on what Glenn said is there anything better to get than the Marchesini polyurethane gromests?
I cant believe this happend as i only put a couple hundred miles on the rims since i got them, not very happy with that especially from a maker like Marchesini.

Maybe call the U.S. Marchesini distributer and see what they will do. I've never had this happen on any of mine, but maybe there is a known flaw in a run of these grommets???

Now i don't know if this will work all that well but maybe turning some grommets out of high density delrin to use in place of the softer rubber might solve the issue. Just a thought.


i do recall one time i had to take out these grommets to get the rim powder coated and i was cursing everything and everyone trying to get them out. They were even a bigger pain in the ass to press back into the carrier. If you can pull one of these out with your finger or pry em out with a flat head screw driver with relative ease, then there is something wrong with them.

Thanks guys...Massi it is interesting that you seem to have the same issue, and that is what is bothering me...I can *swear* I read about other people on some different forums having the same exact problem with these...I am thinking maybe there was a bad batch out there at one time.

Please let me know what you find out, these are not my wheels, they are on JB's bike which is overseas so want to make sure to get the right fix the first time.

they should not have any slop IMO and could be a problem. the rubberizedish ones on certain wheels are for a less harsh ride supposedly but most, if not all will tell you there should be no play and i would call possibly mark or matsu at carrozzeria and see if they can supply you with proper material ones

Just checked mine. There's a little play. Not much. Maybe a 1/4". It's not something that I would think is excessive, but now you guys have me wondering...

SP1 - Marchesini wheels - 15/42 - BrakeTech rotors - (fake radial mount) '08 1kRR calipers - blah blah sig masturbation blah...

Ok earlier this morning i first got off the phone with Marchesini in Italy, i talked to them and found out that these rubber gromets have a 5% failure rate out in the industry (this depends on trackdays, racing, or street comuting, etc... mind you i put 250 miles on these rims 1 track day, mapping on the dyno, and the rest street miles). They gave me the benifit of the doubt and told me to send them my old rubber gromets so they can replace them and also have evidence/proof of this problem from customers as they said they are always trying to improve their product and getting a hold of these parts that are having failures out there is a must for them. Once i told them i was in California they told me to call the 2 main distributors which are Lockhart phillips and QTM. Talking to Lockhart they gave me the runaround and said they are only a distributor which means they dont handle any tech type and told me to talk to Kyle racing as they handle all their tech support . Tomorrow ill call QTM and see what they say. But this is what i got so far.

i would ask around to see if there are another makers that will fit up as sending you more that do the same does not seem like a solutuion:twocents

they are not going to tell you they are bad or faulty, imagine the panic and trouble that will cause them

i went through some stuff like that with Dymag in 2001 and it went legal and crazy quick

call yoyodyne about them as well as carrozzeria etc and for the heck of it ask them what theirs are made of and if they are supposed to have play as marchesini is going to be legal and safe:twocents

Ya i think i might use that solution of using another manufacturers gromets to fix this problem that marchesini has. Dont know yet i wanna dig a little further first. Marchesini actually admited that to me though that these have a 5% failure rate thats really weird. But will see tomorrow.

Haha, I've been searching the internet today looking for cush drive rubber spacers for my Marchesini wheels, and stumbled on this old ass thread. I'm still running the same spacers that I had back in '09, but now they have A LOT of play in them. I can move the wheel over an inch before it engages the sprocket. The only 2 places I've found spacers for sale is MotoSport.com and Amazon (which is still through MotoSport).

Where are you guys getting new spacers?

Same place also bought some from motowheels. I kept noticing little clear chunks all over the hugger and wheel. The new rubber ones are nice

Is it easier to dumd down or smart up?
Just think how much faster the internet would be without porn.
