Hi, I am changing the wheels on my 1200T for GSXR ones and so dumping the 630 chain. I need to decide if I go for the standard 530 or the narrower 520. Has anyone been using the 520 chain on a road bike, if so what type, ie "O" ring, and how has it performed ?
 
have 2 bikes running with more than 100HP and 520 chains - no problem as of yet (one for the past 12.000Km). Make sure you buy a 530 sprocket and grind off the inner side to make it a 520. also make sure the contact area of the 520 chain-wheel (where it sits on the chain-wheel carrier) gets worked on to align the chain. that way you leave more "meat" on the carrier. We are talking about a millimeter or so, but it might be the one that keeps the carrier from having a bolt braking it...

In MV Agusta world, The F4s stock use 525 chain...Guys who race commonly change to 520 and these bikes are developing 170 hp at the back wheel...or so I'm told :)

If you must go O or X ring stick with the O ring.

Much cheaper and base chain is the same.

PS If your riding all weathers sealed chain is good if you are a fair weather
rider the iwis 530 non O ring is bullet proof and on my Bandit 1200 along
with lots of Laverdas.

As a matter of interest next year in BSB a couple of teams in 600 super sport
are running the iwis 1/2  x  5/16 (non O ring) which is 428 in Jap terms.
Against my advice but they recon on a few extra horses, less weight and they
have run for 2 race distances with change. Considering the low cost they intend
to change every race. Huge HP dont need huge chain.
 
Hi Andy,

Listening to advice from the forum 'specially Red, I am planning to fit a lighter chain 520 ? to my Jota and build my 1200 project using a 520 also. The big 630 chain seems to be overkill and I think it rubs a bit in places it really shouldn't.

When I build the 1200 engine I want to have new cam and primary chains to effectively zero time it and I believe you are the man ! :)

So, in the very near..I'll be in touch for your advice and supply please if that's ok :)

Happy New Year !

Having just received a non O-ring 530 chain from Andy to replace a 630 I thought that I would weigh them to check out the weight difference.

630: 2.9Kg, 530: 1.8Kg so 1.1Kg difference between them. Not the most scientific approach using the bathroom scales, but repeated the measurements several times each and they where consistent.
 
The iwis non O ring 530 is lighter than most Jap 520 non O ring (thinner plates).

For road bikes it is good because it has a bigger bearing area.

Jota pick my brains anytime (it wont take long)
