Anybody know company or where I can find a 12 tooth front sprocket for 08 gsxr 1000? It is a 530 chain..

Thanks

I've never seen one. I don't think they make them.

You can make one, take a 14t, and grind off 2, but leave at least 4 full teeth between! Bob

I got mine from Rich Wood of K&S Powersports located in Enfield, CT. He can be reached at (860) 749-3300.

A bit of advice, might be in order. Bob's advice is how them TQ guys change gears in them quick change thing a m bobs.

While you can buy 12 tooth sprockets, made special for us car guys. You need to know that as the front sprocket gets smaller that chain has to wrap around a smaller and smaller radius putting a lot of stress on the chain and sprocket, on top of all that the smaller the sprocket the faster the chain has to move to get around it, with a sprocket that small the chain speed is reaching super-sonic, not good for a chain either. We learned a long time ago to run as big of a front sprocket as we could to get our ratio and if it takes a 12 tooth sprocket to get it we would probably just go up two or three teeth on the rear sprocket or maybe go to a different transmission gear. We usually carry 3 different chains to the track to make gear changing easier for us.

Not being a smart guy, but what is the difference if you run a smaller front sprocket or were to go to 1st gear. Wont both of those spin the tranny output shaft faster? Trying to get to a 13.5 final ratio...

Smaller radius = fewer teeth = less contact surface, more localized stress on the individual links.

It's a kinky chain thing "Most people just don't understand". For the Center you are probably OK BUT it will shorten up chain life quite a bit, that stuff just doesn't like to be kinked up. Bigger is better.

Did you ever try to take a lug nut off with a 1/4 inch drive ratchet?

You're thinking of it backwards. As you go up in gears in the transmission the output shaft spins faster. That's why you'll be going faster in 5th gear at X engine RPM than you would be in 1st gear at the same engine RPM.

Are you serious or you just screwing with the guy about grinding off two teeth??
