GT500 chain

428! Where do you find a heavy duty 428? we wear those out on our CB160 race bikes but the chains we buy are usually consumable items. Maybe it's time to search for a better 428

Well, I have decided to get a DID 530NZ. It is $80.99 from 'Motorcycle Superstore'. It is rated at 8,600 lbs. tensile strength, we will see......

I'm still tossing around the idea of lathing one side of my spare Titan sprockets by the toothed sections down to a 520 width.
This will allow me to add no spacers and use the X-ring 520 chain, which I already have in my parts stock.
A non o-ring chain needs a lot of care to last, especially if you do a lot of constant high speed riding.

In case anyone is interested, I dug out Jughead's post on converting to a 520 chain for a T500:

I found the Sprocket Specialist rears were about $55 to $59 per when I ordered them. The fronts I found on Ebay for around $10 per sprocket. And I was able to find 13, 14, and 15 tooth fronts.

As for a chain, since this set-up is narrower you can fit a 520 "O" ring or "X" ring chain with some clearance to spare. I've found the RK GB520MXZ3 (non o-ring) to work well and have excellent tensile strength. Best of all they turn up on Ebay from time to time for around $50 a chain. I ran one on the GT500 based race bike I bought from Mowgli with no problems so it should survive street duty just fine....

Slight change of plans. Am now getting a RK chain and have ordered both sprockets from Wemoto in Britain. It seems very hard to find a stock rear sprocket in the states for a good price. They were about $54.00 with shipping, so the price to me was pretty good.
