Alloy sprockets on the street?

[Aussie Ninja]

I'm going to a 520 chain and 15/43 in the near future and I can get this for $230 AUD at my door.

I like free power by doing things like using a nice light alloy sprocket. But a few people have told me that alloy sprockets over heat, get soft and chew out on long trips. I am planning to ride my scoot to brisvegas on my next holidays but I don't want to get there and find my rear sprocket a toothless wonder.

Anyone had this happen to them

It shouldn't be a problem. I ran alloy 520 rear sprocket on my zx9r for 3 years with no problems. Race bikes will get hotter than street bikes so I'm sure it won't be a problem. Most ppl will also recommend getting them hard anodised, but I had both and they didn't seem top wear any different.
I just bought some stuff from Sum Of all Parts and it was sent out today. The told me they had the stuff in stock 2 weeks ago when I enquired then payed for it, but it turned out they didn't and it has only just been sent..
I'll be releived if and when it turns up...

Tell them you know Dave / MadKaw from Sydney who bought the ZX10r rearsets, as they may look after you as they stuffed me around...
They should remember me from the amount of e-mails I sent them..

im pretty sure the afam that im running are alloy??...i think a lot of ppl use alloy, over steel..yes they arent as strong, but there lighter...
i think ive got 12000km on mine..and i got abt 36000km out of steel...still dont need to change alloy yet..

They might have had their chain to tight.. and/or not well lubed.. creating more heat in the chain..


if they were no good, i think we'd all know to avoid them.

hi Oz ninja - I used an alloy sprocket on the rear of my z1000 for a couple of years, no worries at all. Did heaps of trips from ACT - Syd/Newcastle and back, keep the lube up and chain tension OK, and you should have no problems. Also did some track work with this sprocket, no additional wear at all. It was a pretty hard T6 ?? alloy, a bloke in Sydney knocks them up to order. Can also recommend The Chain Gang for good service and custom steel sprockets made to order.

I think the fellah's name is Paul ? What you will need to give him is the PCD ( Pitch Centre Diameter) of the standard REAR sprocket. The PCD is the diameter of an imaginary circle that would intersect the exact centrepoint of every bolthole in the sprocket. They vary between 100-180 as a *general* rule. He will also need the diameter of the stock large center hole. ( and of course the # of sharp pointy teeth, that'll rip yourre gutz oot) anybody here like a bit of Python ??

Not sure if he does front sprockets, I always used stock fronts. ( Well, stock as in you can buy it off the shelf........sometimes not using Kawasaki bits )

Good luck. BTW I am not sure if the guy I dealt with in Sydney ( for alloy rears) is still in the game. That was back in '01.

I have a520 chain kit on my '99zx9r and have clocked over 10,000 miles (16,000km) on my setup so far...and it still looks to be in great condition. In fact, I'm riding to Laguna Seca for the MotoGP next week...another 1000 mile round trip!! I use Sprocket Specialties sprockets (http://www.sprocketspecialists.com/html/main.shtml) with the "Titan Tough" hard anodized coating in conjunction with an RK 520GXW chain. While I have used chain wax in the past, I've been using Maxima "Crystal Clear" synthetic lube and have been happy with the results.
Another sprocket I like is the one I have on my YZ250...it is from sidewinder Sprockets (http://www.sidewindersprockets.com) and is called a "tri-metal". It has a gold anodixed aluminum flange mated to a black steel teeth ring mated with titanium rivets and a bonding agent. They have a variety of street applications for most common bikes. I have not used one of these on the street but I have been blown away at the sprocket life on my dirt bike so far.... They cost the same as a regular sprocket and it looks really cool too!!
I think the key to longevety of one's chain/sprok has a lot to do with one's riding style. If you rip wheelies and are hard on the clutch from the stoplight, your chain/sprok will have a shorter life...especially if you run a 520.
To summarize: Aluminum good because unsprung weight bad. If you rip wheelies, stay with a 530, otherwise enjoy the acceleration of ligher weight components found in a 520 setup. There is my 2 cents.........
I'm out, Jay.
