vespa piaggio 100mm rear clutch/driven pulley assembly

vespa piaggio 100mm rear clutch/driven pulley assembly for VARIATED setups

$99.00

:HERE NOW!!

qty:

new vespa variator clutch assembly for variated vespas and kinetic. this is the rear assembly. comes with everything shown. stronger 3 step type bell found on grande n such. very nice i might say.

the driven pulley outer diameter is 100mm, which is larger than what came on stock variated bikes in the US. this means more badass rippin off the line action because the belt starts a shorter gear ratio!! yay!

all bearings and seals are in there and ready to go. comes with the starter clutch and everything you would expect to find here.

NOTE: the starter clutch shoes are installed backwards and need to be reversed in order to work properly. all you have to do is remove the large circlip in the bell and flip the pads. check out the photo and it'll all make sense. also, the starter clutch friction material maybe not be ground to match the inner diameter of the clutch housing where it grabs. if this is the case a lil filing to match to shape will do the trick!

ALSO NOTE: these come oiled pretty well from the factory. please spend a moment with some carb cleaner and a rag to clean the oil off the area where the clutch and starter clutches contact the bell/backside of the clutch plate. if your friction material gets oily it'll make it annoying to start!

ONLY USE THE CLUTCH BELL THAT COMES WITH THIS ON STOCK SETUPS!!! high stall, high power setups have been known to shatter these clutch bells along with the oem stock "3 step" style clutch bells. if you have a ripper setup, do yourself a favor and get one of the CNC clutch bells as they are much much stronger than the stock style bells.

What i got was bent or just poorly made idk	February 13, 2018
taco eater : Alan from Washington, DC United States

using CNC'd aluminum bell and the 108mm plates. only using for clutch because tunable springs.

The bell was oiled as they say but only that. The clutch pads are fancy newer material and not that metal reinforced asbestos stuff.

The outer seal was all dickered. Whatever Italian child or misaligned machine really biffed that seal. Took it out and reseated it. It's better but still binds the clutch a bit. at least it idles now.

I don't know if it's bent or what, but there is what one could argue to be an unacceptable amount of runout. Took the bell off and it is very easy to see the runout when spinning the wheel. wobbley wobbley

I put about 50 miles on it and the pads never really got a chance to bed in completey. the top edge of the pad was engaging sooner.

Seemed ok at best on a mild setup. Ran on a higher powered setup caused far too much vibration and it concerned me. I would like my parts to last and not destroy themselves so I went back to the stock clutch.

Spray this clutch with brake clean first	August 7, 2017
taco eater : Ninja from New York, NY United States

I didn’t need to swap my shoes on a few of the newer clutches I bought from Treats. I did however had to spray the whole clutch with brake clean. It’s a good thing the factory oils these clutches up, I’d rather have to bathe these bad boys in brake clean then have a rusty clutch arrive at my doorstep.

EDIT – (8.7.17) These goobs are putting these clutches on bikes other than Vespas and wonder why they keep exploding their bells. Long live the Rufus Reinforcement Ring! #RRR4Lyfe

Make sure you wear a suit of armor	July 14, 2017
taco eater : Ryan Nash from New Orleans, LA United States

Don't buy this if you have a setup that is anything more than stock. Used on a 60cc kit rode it 5ft and the clutch bell exploded. It sent shrapnel into my tank (huge hole), dented the hell out of my pipe and destroyed my variator.

maybe I got a dud	September 24, 2016
taco eater : JensAroo from San Francisco, CA

definitely saw a performance improvement especially with malossi clutch springs (i went yellow).

but the variator bushing tolerance was off, causing the variator plate to stick or be very hard to variate. lapping seemed to help, but I wasnt able to get it dialed in before my bike was stolen.
