Quick Poll: Interest in lighter sprockets for SBP shift kit.

Light Weight gear

Really not sure if I'm "allowed" to do this but admin feel free to chime in.

I received the quote for an all aluminum 17T #40chain sprocket. Would be about 1/4 weight of the super heavy steel sprocket supplied with the kit. If say 10+ people are interested, would be around 40-50$ for the sprocket. C'mon shift kit people, speak up. Something you'd want??????? Let me know. I know I want one! Just need a few more numbers to bring the pricing down. We all know how CNC small batching works. The more you make, the cheaper per unit.
 
They won't do much for acceleration, or it would be fairly negligible anyway. Losing a pound will have the same effect while you're on your bike but losing the weight ON the bike means it's easier to lift, push pull etc. I have a custom built FS bike that I thrash around in serious rough trails and terrain, less weight on the bike is a must.

Especially if you live in NY and ever have to throw it over a fence to get away from a board Cop. They want to ban aluminum up here now!

So what grade would the sprockets need to be made from to hold up and exactly how thick? I've got a machine that will do it, but I'd have to re-tool it!
 
6061 or 7000 series, anything a normal aftermarket motorcycle sprocket would be made of. Thickness could be .130", tappered teeth. I have CAD files. Would be nice to redo the shaft in alu. too. Or hollowed steel. There goes another 1/4lb.

No. Kings already makes the chain rings in CNC. I'm talking about the 17T motor side sprocket, the solid steel one that weighs 1lb. I've gotten quotes from CNC shops. It aint cheap. Starts to get reasonable in 50-100 qty.
