[buckchuck27]

my friend has a 97 yzf600 and his rear sprocket destroyed, half the teeth r broken off. hes been lookin for a replace kit and hasnt been able to find any. do the newer yzf's or does the r6 from that generation use the same sprockets?

Sprockets are very common aftermarket parts. I have an 01 FZ1 and I have changed to a performance setup. Your local dealer (Honda, Kawasaki, Yamaha, etc) will have several vendors to chose from on sprockets. Most aftermarket sprockets are made of aluminum, which is light weight and will generally not last as long as a steel one. You can purchase anodized aluminum sprockets which will last a little longer than non-anodized. My bike had 22K on the factory sprockets and chain. I now have about 5K on the aftermarket aluminum rear, DID x-ring chain, and new steel front. I do not have any appreciable wear and the sprocket will probably last me 10K more miles. I went down 1 tooth in front and up 2 teeth in rear. My bike tops out at about 157 (read the manual) due to aerodynamic limitations. When the bike is in 6th, the RPM of the motor at top speed is NOT redline. By changing sprockets (change chain too! Sprockets and chain are a "group" an must mesh properly) you affect the acceleration of the bike. By changing the gears you essentially move the Hp and Torque curves closer to idle. You will now have to shift into second sooner, but this just makes the bike more fun to ride. As you make your way through the gears, you will ultimately end up in the top gear at top speed. A 600 can wind forever, so you will probably not lose any top speed and ultimately don't need to be driving around at 140MPH either way. One word of caution: too agressive of a change will induce first and second gear wheelies. I do not recommend deviating from the manufacturer's specifications if you are not willing to modify your riding style to use some restraint on the throttle. Bikes are built "safe" for the general public and it is sometimes a subtle change that allows our vehicle to grow along with our abilities.

Yeah you got that right! My steel sproket lasted heaps longer than the aluminum ones. I tryed a couple of diferent ratios as well, i went 1 down on the front & 2 down on the rear, then 2 down on front and the std gearing rear which goes pritty good. I might go higher on the rear next. I havent tryed an anodized one yet but i am almost ready for a new rear and will give it a go.

i've just about to put a custom rear on my 954. its a aluminium 44 (+2)

just because all litre bikes need more acceleration

my standard is still in perfect condition after 10,000k's

That is where most people say they find the best prices. I have dealt with them in the past. If they don't have the sprocket for your bike listed call them - they can get just about anything. Great folks!

Just get a good aftermarket kit with 520 chain. I have one tooth down in front on my '01, and it's crazy, changing the rear in addition would be even crazier but wanted to keep some highway
