I jam about to pick up a 2000 F4 and I am looking to put new sprockets and a new chain on it.

I just was wondering what the stock sprockets were. As in how many teeth on the front and rear sprocket?

As for the chain, is a 525 good? or should I got with a 520 or 530?

I am very mechanically inclined and can rebuild just about anything, just kinda new to motorcycle stuff, so any help would be awesome.

Thanks dudes

 

2000 F4: If you want it to be stock:
Stock OEM rear sprocket- 45
Stock OEM front sprocket - 16
Stock OEM chain size - 525 (D.I.D. chain OEM)

If you want to go aftermarket, go w/a 520 (narrower chain) conversion kit, which will include applicable sprockets for the 520 chain. You can go stock sprocket sizes or change to your liking. There are threads here on the forum telling of experiences w/ dif size setups.

Good luck.

 

Now what's the advantage of going to the smaller chain?

 

It's lighter, but it wears/stretches faster.

I'd recommend the 525. Keep it stock.

 

It may sound silly that it loses a couple pounds to convert to the 520, but the weight is all rotating mass. So the weight loss improves throttle response and frees up a noticeable amount of power. I think the conversion is well worth your money. Also I would go up a minimum of 2 teeth in the back if your changing sprockets. + in the back - in the front for quicker exceleration. 1 tooth down in the front is equivalent to 2 teeth up in the back. I put a 15 and 48 on my bike and since you've probably been around cars it's like running a set of 4:10's compared to 3:55's in the rear end. As for the faster wear if you buy a high quality chain and sprockets the reliability won't be all that different.

520 conversion + more teeth = surprised new 600 and 750 owners who can't keep up.

 

I went with stock gearing and 525 size chain on steel sprockets.

I liked the standard gearing. Larger rear sprockets will make each gear shorter you end up shifting more often. Plus in 6th gear on highways you will be running a higher rpm, which makes for a buzzy ride.

One tooth change in the front is closer to 2.5 or 3 teeth on the rear sprocket.
