What Chain and Sprocket's do I need?

[Couger]

Hiya all,

My chain and sprockets are in need of replacing, ive got a 2000 R6, but being a bit dopey don't know what to describe when ordering.

Can anyone tell me what I need, and where is good for prices on Renthal ones.

Cheers.
Cougs.

535 pitch chain is standard, but going for a 520 is sposed to be improve pickup, theory being a lighter chain moves quicker after you open the throttle

then just ask for standard R6 sprockets to fit a 520 pitch chain

The standard chain is 532 pitch.

The standard gearing is 16/48 teeth, but it might be worth considering down gearing it, performance wise it makes a big difference. Maybe try something like 15/49, I ran that for a while and it was much better than the standard.

As Mr Goose says, changing to a 520 pitch chain can help the engine spin up faster, while also reducing rotational mass and overall weight slightly. A lot of racers use 520 chains so all the major retailers will have them. You can pick up a pair of Renthal hardened brass sprockets for under £60 and the chain for around £80 - £100.

Down gearing it will improve acceleration, but might cost you a couple of miles per hour off your top speed. In my opinion changeing to 15/49 isn't likely to effect your top speed much if at all, but for doing wheelies and for track riding it will give you an edge over the other 600s.

So if you want standard gearing and pitch ask for -

16 tooth 532 pitch front sprocket for an R6.
48 tooth 532 pitch rear sprocket for an R6.
Plus a 532 pitch chain of your choice.

If you want to downgear and use a lighter chain ask for -

15 tooth 520 pitch front sprocket for an R6.
49 tooth 520 pitch rear sprocket for an R6.
Plus a 520 pitch chain of your choice.

In my opinion downgearing is one of the best mods you can make for the money, I'm sure others will agree.

Thanks very much guys,

I take it most shops will be about the same price for the parts? Expensive business, especially since I just replaced the regulator rectifier.

How are you both by the way?
Cheers.

Not too bad thanks mate, off to Cadwell next friday.

I got my chain and sprockets from demon tweaks, but as you say there won't be much difference in price between retailers.

This place is meant to be good for chain and sprockets, I think Ste got some for his ZX6 from them.

Cheers dude,

Have fun at Cadwell, now that I'm "up country" I should be able to get involved in some.

How hard is it to fit a chain and sprocket set myself, or should I let a garage do it?

Cheers.
Cougs.

Do it yourself mate, it's really easy, shouldn't take more than an hour. Even Luke managed to do it with a bit of help from G.

Have you had the rear wheel out before?

Nope never!

Which is why I am a bit wary, do I need any special tools to drop the wheel, or put the sprocket and chain on?

Cheers!

You'll need a 32mm socket to undo the rear wheel, but to be honest this is something that's worth getting anyway just so you can adjust the chain when necessary. If you're getting a new chain you'll likely need to adjust it after a few weeks anyway as it will stretch a bit initially.

Apart from that the only thing you'll need is a chain rivetting tool. I don't have one, so when I swapped my chain and when luke and Bendy did their's we just pushed the plate on as best we could and then rode slowly up to a bike shop and gave them a fiver to rivet it.

It's not a hard job overall and something that's probably worth learning to do. Just depends if you want to get you're hands dirty I guess.

Cheers Dusty.

I'll do that, I like getting my hands dirty, just paranoid I'll break something, bike tops out at 120 ish as it is! Bugger knows why that is.

Whats the deal with the riveting tool, pardon my ignorance, but do you need to buy loads of rivets, or is it just one?

Cheers

The bike tops out at 120mph? That is odd, you did derestrict it didn't you? Might be worth balancing the carbs (Laura's suggestion).

The chain will come with a link that is in pieces - one plate with pins on and one with holes in it. You'll need to put the one with pins on through the main chain and then force the one with holes in over the pins. When I say rivet, I mean bend the end of these pins over to stop the plate coming off.

If you look at the chain you have on at the moment you'll be able to see that the end of each pin is flattened off on four sides.

Cheers Dusty!

Yeah dodgey isnt it. Deffo derestricted it, plates and stops, there are a few dead spots, so hopefully a carb balance will sort it out, 120 just seems so slow though.

Currently in talks to swap for a 748, not sure.
Cheers.
