Anyone used one? Just a gimmick?
The stock New Bonnie ones had a rubber centre, still using it so I can't say if it makes any difference :^_^
all of my steamers OEM sprockets had rubber centers too, never really noticed anything different.
My steamer had an OE Triumph 'silent 'sprocket on when I got it, I changed the whole kit and I honestly can't say it became noisier... It should make a difference - in theory. The manufacturer is a well known supplier of OE chains/sprockets since the 70's apparently... if they don't cost much more than the JT ones, then I'd be tempted to give them a try... did you sort out the revs issue btw?
Haven't had a chance to look yet JD. Maybe w'end'? It's more of a little 'annoyance' at the mo. Bike runs nice otherwise.
Come to think,when I first changed the sprocket on my Daytona,it had the factory one fitted,which is similar. I didn't notice a difference with the conventional one?

Are you thinking of changing for one of the new 1200's ST ? I quite like he new 'Street'
So how much quieter is a 'silent' sprocket?? Can't say I've ever noticed the noise from the running gear of any chain driven bike I've ridden..... Except when I over tightened the chain on Stanley the Steamer on my way back from Alaska :augie
Silent drives are as likely as paperless toilets IMHO seen and worked on too many to be hopeful. Even induction drives make a noise.
Glad they've kept the 900, I think that's a shrewd move, I do like the 1200 Thruxton R but I've invested too much in mine and the power to weight and torque is almost the same, the only thing I'm missing is a 6th gear and it would pull it :nod
Back OT: Asian restaurant - customer - waiter, this chicken is rubbery. Waiter - ah fank you very much :hat10
How deep into the archives did you dig for that one Niall... dissapointing, you're capable of much better :icon_rolleyes:
I was in an Asian restaurant recently..Japanese. I got talking to the waiter who was quite elderly. He told me that he was a 'kamikaze' pilot in the war,and his 'call sign' was 'chow mein'. I remarked that I thought that all kamikaze pilots sacrificed themselves in battle? 'Yes' he replied,'but I was chicken -chow mein' !
Would it be possible if the cushion sprocket was to dampen shock loads into the transmission rather than to simply run quieter?

It's just rubber bonded onto the outer faces of the sprocket, not sure if the one JD's talking about is something fancier but I'd have thought that would be redundant with the cush rubbers in the hub.
From what I can tell, the chain side plates hit the rubber bit and that reduces any clatter - I've only noticed a badly adjusted, mis-aligned or very dry or worn chain to be noisy.
maybe its to stop any resonating noises at certain speeds... Manufacturers don't usually do things like that unless neccessary.
