G'day,

I'm looking into getting custom made lighter weight sprockets made for the motor side in the SBP shift kit, i.e the 17T and possibly shaft and 10T sprockets. The current sprockets are solid steel with huge overkill collars. 17T sprocket is .8lbs!!!!! Just too heavy, I'd be getting them made out of alu. For CNC obviously margins of scale exist so just trying to gauge how many people here would buy spares if I have a small production run made. You'd be looking at somewhere between 50-120$ per sprocket. Let me know!

Cheers.

Woops, just read the sticky? Guess my post is out of line? Any place I can post something like this? Delete at will.
 
I can't spend that kind of money on a sprocket...
Wouldn't make sense, either.
A CVT is two hundred and covers it all.

...so there's your competition, can you beat them?
Why would a vast majority of the MAB crowd choose your product?

Good luck

Shift kit sprocket

CVT, as in continuously variable tranny? Never seen, what does
It look like?
Cost could be less aswell, havn't received a quote back yet.
Not really a product per say, would have a few spares to sell possibly from a single production run.
For myself, the weight savings is worth the price. I've bought a set of
Alum chain rings for the shift kit and it makes hella difference compared to
The stock steel rings and didn't have to slave and drill lightening holes.

your fb is welcomed

Hey M,

I'm not exactly clear what your goal is, yet imo, this should help almost any small engine that produces enough power to deal with the additional mass and associated drag.

The link is cometkartsales.com and there are a number of other vendors and similar products.

Good luck

Light weight sprocket for shift kit

Oh, goal is all about saving weight, not trying to reinvent the wheel, just trying save a little weight on the shift kit thats been around for a while. That CVT looks awesome..... But it's pretty complex, probably weighs a good bit and kind of brings things into the motocycle" category. Thanks for link and diagram, will check it out.

Great goal, M... I don't mean to take away from that objective.
I dunno what the comet weighs, but they'll have all that info at their site.
Thing about it is that everything but a single driven gear and the brake are all that are needed on the aft end... Still, I'll bet it's heavier, though.
Good luck on your quest!

If you do go with lighter sprockets please posts results MTB. I'm interested in finding out if the lighter sprockets will help with acceleration. or if it will just save a little weight.
 
Shift Kit weight reduction

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.
