I don't have that many miles on the sprocket and chain. Just was concern that the parts were defective or something. This is my first set from vortex eversince I went to a VFR swingarm.

 

Yea aluminum sprockets SUCK...i had one on my f2 and it looked exactly the same, chain started jumping and i'm like wtf...barely made it to the bike shop

 

^^ same thing happened to me. Switched it back to Steel.

 

Damn thats the same thing that happened to my vortex sprocket just not as fast but mine looked worst that **** was ROUND no teeth but maybe 3or4. I upgraded to a SUperSPRox sprocket which has steel teeth and an almunium center to keep it light, plus its black and gold and goes along with my gold RK x-ring chain now it runns lovely and will definitly last with steel teeth , the sprocket runs about 90.00 all together FROM SUPERSPROX good luck stay safe

 

i think the whole aluminum and/or 520 conversion thing was pretty much designed for track use where these parts get changed out much more frequently and shaving 1 pound actually makes a crap. if i want to go faster, ill just skip a few cheeseburgers..

 

I'll ask, how was the tension on the chain? And that no OEM sprocket who ever said that. I've hard mixed reviews on Vortex sprockets, but good n bad like this. My driven gears are still goin strong.

 

You know, now that I think about it the sprocket may be a Parts Unlimited sprocket. Whatever that is lol. Yeah that's me that's trying to sell my bike. Horrible timing for this to happen!

 

sprockets aren't that much...just return it stock if your trying to sale...screw aluminum though...save weight reductions for the track

 

whats the stock chain size? plz

 

The F3 setup i had on my F2 was 525 front and rear STEEL sprockets with a 525 chain(duh lol) i don't remember the amount of links though, sorry
