new chain needed cbr 929? (with pics)

I recently had my cbr 929 mot'd in the uk.

Passed no problems, advisory for the chain having too much free play, so I have tightened it to the first picture below.

However, it is now on the penultimate marker, as you can see from about below.

I recently saw a mint 900 mile version of my bike, with the chain wear sticker on it, the 2nd picture refers. Basically, the indicator
for where my chain is now is well into the worn chain area.

Before I swing for a new chain and sprockets, I wondered if there were any opinions or advice about the matter?


Is it definitely time for a new chain, or is it okay to ride on a bit more?

If it is new chain and sprockets times, I was going to go down the standard 16 tooth front and 42 tooth rear as this is what is on at the moment albeit oem, with Renthals, and a DID chain,
unless anyone has anything else to recommend?

Looks worn to me and from my personal experience I adjusted mine when I bought it and came out at the second to last mark like you. After riding maybe 200miles I was missing teeth on the rear sprocket.

Don't play with it. Replace it.

Also if you're not aware the bike is already wheelie prone so you might want to consider keeping the stock gearing for a time.

Re: new chain needed cbr 929? (with pics)

Thanks for the replies, apologies for the delayed response.

I am going down the renthal 520 pitch 16 t & 42 t front and rear, and a 520 pitch did chain, about 100 pounds for the
lot separately off ebay in the uk.

I will update this once it's been fitted with a few pics.

do you have a link to the items youre buying? did you already order them? reason i ask is 100 pound or 130$us sounds like a really low price paticularly if youre buying them separate.

did makes several models of chain n just dont want you to get something not quite up to the task. specially considering you are dropping to the 520 pitch.

on a side note i think did and renthal are both pretty decent products. personally, i think rk makes the best and i place did and ek pretty close to one another.

id recommend springing for the gold chain. they resist rust a lot better than the standard.

drop a link in on what youre considering. btw just based on the pic id say it was for sure time for a new one.

Re: new chain needed cbr 929? (with pics)

personally the vx2 wouldnt be my first choice, but i suppose itll suffice. its rated for 750cc, but i would say the 929 and most modern 750cc sportbikes both produce around 120ish rear wheel hp.

id still recommend the gold version for a few pound more. as mentioned they resist rust much better than the plain steel. something youll notice quickly even if you take good care of the chain. paticularly when you store the bike over winter.

im kinda confused why you would drop the pitch to 520, something thats only benefit is a very slight weight reduction. which in turn creates a very slight acceleration improvement.

on the race track where you slow down, then accelerate out of several corners this slight boost in acceleration can cut a few .00ths off a lap time after you multiply it by the number of turns on a track.

however, street use... its not like your trying to shave off five hundredths ofa second on your trip to the corner store, or even through your favorite canyon. its a small difference, but at a cost....

obviously the cost of dropping to a 520 pitch vs the oem 530 is longevity. the 520 is going to wear out faster. less metal doing the work of more.

whats most confusing about the setup youve listed is youve combined a 520 pitch chain with a -1 rear sprocket. which means your bike will have a decrease in acceleration vs the stock 16t front and 43t rear. so the only advantage to dropping pitch to 520 is now null n void because of the sprocket choice.

its more common people drop -1 on the front sprocket with a 520 kit to try and increase that small amount of acceleration in combination with the 520 chain. but dropping a tooth in the rear will cancel out any acceleration you would have gained with the 520 kit.

if you want to maybe lower rpm for highway cruising a better option would be add +1 on the front sprocket. its a change thats less dramatic. -1 on the rear is like adding +2.75ish on the front sprocket. closer to 3 than 2. its going to be a reduction in acceleration you will notice for sure. so just doesnt make sense to combine a 520 pitch kit and a -1 rear sprocket.

the 108link chain should still fit with a -1 rear sprocket.

did is a respectable name in chains. i used renthal sprockets many times on my dirtbikes and they held up well. ill say as well the aluminum rear sprocket wont last as long as a steel sprocket. paticularly in a 520 pitch where a 530 is oem. just something to be aware of.

ill say im currently running a 520 kit with an aluminum rear sprocket on my 954. i got a killer deal on the kit and probably like you, at least wanted to see what the deal was with a 520 kit. im going back to the 530 all steel as soon as this set is done. im at 10,000ish miles now and it wont be much more. the difference in acceleration is negligible and doesnt justify the decrease in life.

edit: just did a quick look around after re-reading your op. and oddly enough the oem tooth count in the us is 16/43 but looks like over there the oem is 16/42 so excuse my ignorance on that subject. not really sure why it would be different here vs there. ?

Re: new chain needed cbr 929? (with pics)

Kev,

You are correct, the uk 929 is 16 t front, 42 t rear, obviously uk bikes are 1 tooth better than us bikes ;-)

The gold version of the 520 pitch 108 link chain is this :-

DID Gold HD X-Ring Motorcycle Chain 520VX2GB Pitch 108 links w/ Rivet Link | eBay

60 gbp, only 5 gbp more as you say, so I would definitely go with that one, thanks for pointing the obvious out, this is why I asked for opinions ;-)

Alternatively there are complete kits, in 530 pitch (the chain anyway, doesn't mention the sprocket pitch) such as ...

Honda CBR929 RR Fireblade 2001 DID Gold X-Ring Chain & JT Sprockets Kit Set | eBay

for 90 gbp, gold chain etc.

Does anyone know what JT sprockets are like?

Finally, there is a complete kit in 530 pitch, Renthal & DID.

http://www.ebay.co.uk/itm/Honda-CBR9....c100005.m1851

That is 140 gbp though.

Need to order shortly, so more opinions welcome!

I have tried two different JT brand sprockets over the 14 years I've had my 954 and was "none too impressed" For me, they seemed to wear far quicker than Renthal, OEM, and "SuperSprox". I have tried one on the front, and one on the rear in both 530 and 520 "pitch", but not in the last 8-10 years.

It's quite possible they've improved since I've used them, but now am pleased with a steel front and aluminum (or alloy) rear, and exclusively use Renthal and "SuperSprox" (520).

note: A key to sprocket (and chain) longevity is establishing and maintaining proper chain tension

Re: new chain needed cbr 929? (with pics)

ive had good luck with jt sprockets. i could toss a coin between jt and renthal and be happy with either outcome.

if you wanna try the 520 kit of course its gonna wear out faster, but looking at your listings the 530 kit cost 24% more than the gold did renthal 520 combo. id guess thats just about how much faster the 520 kit wears. so cost of ownership kinda comes out in the wash i suppose.

at the end of the day its a chain n sprockets. youll replace them soon enough. so if you find the 520 kit wasnt what you had hoped for you can always switch back to oem pitch next round.

whats important is sticking with a quality product thats rated for your machine. everything youve listed is appropriate.

Re: new chain needed cbr 929? (with pics)

Red Rocker has an OEM style DID 530, with a steel front and hard anodized aluminum Sprocket Specialties rear. It's seen limited use in the last 20 years, but that's how long the set up has been installed. It seems like an over engineered industrial strength set up compared to my track 99 900RR, which I've put on a 520 DID ERV3 gold Racing chain with a steel JT front and an aluminum JT rear. 6 15 minute track sessions and it all still seems brand new. As Unslow said, proper maintenance goes a long way to keeping those items in tip top shape.

The pics show the difference in size, and I am now a believer that the 530 set up is overkill, but I'm not a daily rider.

Re: new chain needed cbr 929? (with pics)

A bit of a late reply I know!! UK bikes got the 42t rear but you can run the 43t rear fine, I have one on mine; it gives slightly more acceleration and slightly less top speed but I don't do 170 mph very often so prefer the extra go, especially as I ride with guys with newer 1,000cc bikes every little helps! If you're worried about the speedo reading true you can get a Speedo Healer plugin box that can correct it.
