Australian/Italian Imports has advertised Regina 520 oring chains for $69 in AMCN. Any good or bad thoughts on this?

Regina..?
good chains
520?..is an OK one depending on what you put it on
..pls not a 9R or 10R though

and $69? fell off the back of a truck price
say 50% of RRP

cheers

nuthin wrong with a 520 smitty...i run one on my blade (i kno i get all the jokes-but i seriously runs similar power to a 9r...a lil more i think)..and im sure most of the race teams run em...
life expectancy of a 520 isnt that of a 530, but its not that bad...get more gearing options too most of the time...

Its going on my '98 6R with a 43 rear sprocket.

should be fine on a 6R or 7R

I know neka uses one, but
I wouldn't use one on a 'Blade or 9R ..lifespan would be very short

Steve at Midtowns 10R Racebike runs a 520. I am going to run one on the 7 too. I guess trackbikes do not really do enough kms to worry about it too much.

a 10R trackie will like a lighter weight chain (520 v 530)
that might last 2 or 3 days at the track before its replaced
It'll be fine on the 7

cheers

i wish id written down how long ago i put mine on...but if ive already got abt 12,000km on it i think, and 2 track days..countless wheelies..it cant b too bad....

Sold out yesterday. DOH!

Are all motorcycles chains made out of steel BTW? Wouldn't titanium be a better material (stronger/lighter)?

Ok, it might cost another couple of bucks but it might be worth it

where do u get these $69 chains from

ummm no
titanium is not the wonder metal for all occassion most people think it is....

Titanium is a poor conductor of heat...believe or not (this is good and bad)
Titanium during manufacture has a strong alloying tendency or chemical reactivity with materials in the cutting tools. This causes galling, welding, and smearing along with rapid destruction of the tool.
Titanium has a relatively low modulus of elasticity, if you like, more “springiness” than steel. This causes problems during manufacture where the work has a tendency to move away from the cutting tool unless heavy cuts are maintained or proper backup is employed. Slender parts tend to deflect under tool pressures, causing chatter, tool rubbing, and tolerance problems.
Titanium’s fatigue properties are affected by a tendency to surface damage if certain machining techniques are used. Care must be exercised to avoid surface scatches, especially during grinding. Any loss of surface 'integrity' must be avoided. If this precaution is not observed, a dramatic increase in material fatigue can result...in other words
it breaks!
Titanium’s work-hardening characteristics are bad which leads to chipping rather than smooth machining. This is also an issue with 'rubbing' contact
where it gets harder and harder

basically
a titanium chain would work but would be more susceptible to breakage
and would be very much more expensive. It would wear steel gears
very quickly (you would use a titanium gear if possible)

overall ..great for aircarft parts or bike headers
not nice for a transmission chain

hth

cheers

Cheers for the info Yoda, just interested in why no-one had tried it

Probably a bit late, but I've run a Regina 520 o-ring on a ZXR superbike for over 3 seasons ; it was used for one race weekend by TKA on a ZX7 before I got it, and while it's now a bit stretched, it's certainly not yet terminal. in fact, it's about to see it's days out on an old YZ125.

Cheers,
Brian

Just so you know, the ZX10R runs a 525 chain...best of both worlds
