Any benefits? Thought I saw a thread on this but cannot find it so sorry to post again. Less inertia?? Less strain on chain ?? I know racers do this, but is just weight loss or other benefits?
Compact Toolbox Flywheel Holder
I bought a lightened clutch basket a while back at Wickstead, thought I would check the weight savings... (I cant remember the make of it, but its claimed to be Italian) Its actually heavier than the original solid GP Italian one that I was taking off...
The MB ones are lighter and seem very well made, I cant remember how much lighter, but I never bought it for the weight saving, I bought it cus it was recommended by the makers of the Foxhat spider that I was fitting, as the basket is deeper so lets the plates free off a little more than a standard sprocket would...
If your after engine response from light weight internals the flywheel probably gives a better option for weight saving... Any sprinters would machine the weight off anything that spins even the kick teeth removed off the first gear as any weight advantage is a plus, but the rotating parts even more of a plus...

I know the MB ones are 'banded' and obviously s**t-hot quality....but never weighed one so dont know what they come up as....but these other 'lightened' ones (usually 5-plate affairs) are as you say usually much heavier than original italian 4 plate jobbys.
It because of the thickness of the metal plate on the base...sure the 'lightened' 5-platers have cut-outs...but the metal is loads thicker.
For my racer, i took an old italian one with the thinner base (already lighter than most) and made swiss cheese out of it with a drill, i then used a porting tool to cut out the deeper seats for the clutch plates for my FOXHAT 6 plate set-up.

I was just having a look on the Scooter Center website and they list the weight of everything they sell.
Here are the weights of the Rear Sprockets they sell:
MBD 564 grams
Tino Sacchi 870 Grams
Sil 770 Grams
So the light weight Tino Sprocket weighs 100 Grams more than the standard Sil one
