Sprocket Weight

I see all the time when looking for sprockets that some say "holes drilled for weight savings". I am just curious if this is really worth anything. I know about rotating mass and all the but the amout of weight is so tiny I cant see it making that big of a difference. So I ask you all; in the real world is it worth spending the extra $10-15 on the higher end "lighter" sprocket or is it all just crap?

Honestly I cant say if the weight makes a difference, but I put a bigger front sprocket on my DRZ400. I think if your gonna do it, might as well spend the extra 10-15 bucks and get a higher quality sprocket. Cause it will probably last longer, but I am a big believer in "you get what you pay for"

Sometimes yes and sometimes no with you get what you pay for. I have bought stuff that ended up being over priced junk that was priced higher because of a name (example Pro Armor bumper) That's what I'm tring to find out if these are worth it or if it is just glamour

I bought a "Driven" front sprocket for my Suzuki, and it has the holes in it. It was 35 bucks and I am happy with it. I dont know if they Driven makes them for the 700xx. Good luck finding what you're looking for Crash21.

So I did a bit more digging online and this is what I found for anyone who is interested.

For every 1 lb you take off rotating its equivilent to taking about 8 lb off the bike. So 11 lb of rotating might be like taking 80-88 lb off your bike. I might be a little off.

Also from what I read,
For an HP guess I would say it could be the same as gaining 4 -5 hp. Based off 11lb drop

So for the front sprocket the difference is about .5 oz which equates to about .0375 lbs. So the long and short of it is no its not worth it. If you happen to need a new front sprocket and you can get one for a good price sure it wont hurt but dont go out and buy a new one for that reason.

I answered my own question just thought I would post the results incase anyone cared.

rotating weight is huge,, but a few 0z in a sprocket vs a few lbs in a tire/rim change is almost not worth thinking about

rotating weight does equate to a bigger gain then bike weight, bit it comes down to hp per lb... on a bike that weighs 500 lbs u need a huge bump in hp to see much difference in acceleration
