who has good strong sprockets?

[reds919hornet]

just wondering who makes good strong sprockets. looking for my street ride. put a vortex on maybe 10k miles ago and it has teeth that are broken. chain and frt. sprocket still look good.

i like the options that 5th gear sprockets have as far as designs but thinking i wanted to go with steel instead of aluminum.

just so you know it is for an 06 cb 900 f or honda 919. the 93-99 cbr 900 rr sprockets in the 520 are the same.

thanks
