My New 520 Chain Conversion Kit

[Zed]

Just bought myself one of these thru eBay, should be here in under two weeks hopefully, it cost me about $150 less to purchase this online that it would have locally!

Stock chain on the 954 is 530, the chain in the kit is a 520 Premium GB520GXW X-ring chain and Master Link in gold, so will match the brake calipers gold colour.

Stock front sprocket is a 16 tooth, the kit contains a 15T.
Stock rear sprocket is a 43 tooth, the kit contains a 45T, and the design and finish of this unit is a real looker and performer, so the seller says.

I checked out my current sprockets last nite and the previous owner left the front sprocket at stock whilst changing the rear to a 42T?? Maybe that's part of the reason my current chain is a bit stretched? Partly why i'm getting this new kit as well as wanting to change the gearing to the optimal drive ratio of 3.00, which according to the seller again, has been tested in both road and racing environments...have a read:

"520 Conversion Kit for your 929 or 954!

As soon as Honda ditched the 16" front wheel and started making the 929, it immediately surpassed all of the other open class liter bikes. What prevents the 929 or 954 from beating up the 04 models? Not much, having the right gearing makes all the difference. If you've ever felt like your bike was going to stall coming off the line- or that it needs to much gas to get going - you will never feel low on torque again after installing this kit on your 929!

This fits all of the 929 and 954 models and increases power response across the rev range. Dyno tests prove that you can reach peak torque and HP an average of .4 seconds faster than stock!

Stock Sprocket sizes are 16 tooth front 43 tooth rear which has a final drive ratio of 2.69 The optimum ratio is 15 tooth front 45 tooth rear which has a final drive ratio of 3.00

Extensive testing on the street, eddy current dyno and on the race track have proven that this is the optimum ratio for your bike, however you may choose any combination of front and rear sprockets for your application.

Front sprocket part 3273
Rear sprocket part 251A
Your RR requires a Premium GB520GXW X-ring chain and Master Link for optimum performance, and it is included with this kit."

So I'm looking forward to seeing and feeling the improvements! Roll on KB Stunt Day!!

was looking at getting a similar setup for the R6, it doesnt look so racey without the gold chain - but my wallet wouldnt budge when i needed a new chain last time

Upping your wheelieability Zed? I would have thought that chain stretch would be a greater concern with the lighter chain tho.

where does the speedo for the cbr get its signal from? if its from the front sprocket then it will cause the speedo to display the incorrect speed.

Yeah i'm gonna see how far out she goes and then make the call whether to get it recalibrated or not...

Shit Zed thats gonna make a HUGE difference!. Going down one on the front is like adding 3 to the rear so you now have like 6 more on the rear!. You'll be out of first gear pretty quickly but the front will lift so bloody easily. You will have to sort out your speedo though.

Nice Zed, should make a huge differnce to the bike, i dropped one on the front and now it power wheelies in 3rd at 140kph - 180kph
Dont worry about the speedo, who uses em anyway?

So wot speed is she now coming up in 2nd?

[Lou Girardin]

Why did you go to a 520 chain? It might be right for the track, but I'll be surprised if it lasts very long in street use.

Guess i'm more interested in the buzz factor than the durability of the purchase. Must we always buy the most economical parts? I think not.
