I've only seen independent manufacturer's who make billet alloy ones with a bonded steel cog ring on ebay...stupid expensive though..,..more bling than practical. Perhaps Solo Speedway specialists....

I wondered about alloy versus steel sprockets with weight saving. A poop before a ride would have the same effect as a alloy sprocket. :D

   Couldn't agree more, not to mention how easy alloy sprockets bend and wear! I had Renthal rear sprockets twice on my WR200 and I'll never do it again. It just isn't worth the money and the difference in weight is not huge. From what I saw Afam makes aluminum (7075 T6) sprockets for all the IT range apart from the 400. But it does for DT400. Maybe just not into the catalogue, yet similar to another model. I am sure Renthal has some compatible too.
Check http://www.renthal.com/home.asp and http://www.afam.com/html/product-catalogue/index.html

   Cheers, Fanis

Very true !

However, I've still got those lovely aircraft alloy Allen screws I bought 25 Years ago. Been waiting for the perfect bike to use them on !
Weight saving...... 100 grams if I'm lucky !

I'm not so much interested in finding alloy sprockets, more so finding one that has six holes in it like the originals. Most of the sprockets you find have got triangle shapes cut into them

I have an AFAM alloy sprocket on my TT, I have been very impressed by the wear, or lack of. The sprocket also looks like a steel one so it looks very original. The idea of weight saving means little in the overall scope of things as bike and me are like more than a quarter of a ton and thats at my ideal race weight of 120kgs even after a poo.

I also use normal tubes,  I haven't found any more punctures using them either.

But the weight savings on your wheels (however small that may be) add up to less unsprung weight. Not that I really go hard enough for it to matter but nothing kills an enduro bikes suspension handling like unsprung weight.

That would be good mate. All I'm really after is a sprocket that looks just like the original one.
