Hi, thinking of putting a 520 chain and sprockets on my hyper 1100s. What are your thoughts on this idea?
Personally - I would never step down a chain size on a big twin, an Überthrapper - because it might snap the bugger and do this? What are your reasons for doing so? Weight? If you do decide to do so I can help you out with a case-saver as below to stop you having an Expensive Accident...
G'Day Hugh 525 is wider and spreads the load over a slightly larger area, 520 is narrower and will wear the sprockets quicker, because the same load is going through the chain. ....I pick this off another web forum........
Renthal-style lightweight steel & hard-anodised rear sprockets would save some weight on your drivetrain but keep the same chain?
RENTHAL REAR SPROCKET 39T DUCATI 848 MONSTER MULTISTRADA HYPERMOTARD | eBay etc... ebay is your friend! Get a GOOD named chain, not some Wongtongfong thing no matter how many sequins & bejazzle it has... :biggrin:
My 748/853 ran a 520, can't remember if that was standard or if I changed it early on in ownership. It would have had more power than the Hyper and weighed more so chain probably had a harder life than it would on a Hyper. Needed C&S around every 9K miles. No other problems whatsoever. Renthal steel front, ally rear, DID or equivalent chain. Wish I'd copied all my notes before passing to new owner.. or hadn't sold it at all.
Most if not all race bikes use 520....... even 200bhp+ bikes :wink: Just make sure you buy a decent one.
And make sure you maintain and change both the chain and sprockets far more often. Race bikes do get used harder but also less frequently with higher maintenance regimes and are exposed to less road shite.... I looked into the change for a road going 848 and after a lot of research decided to stick with 525 when I changed my rear sprocket size.
Sorry Jack , DID website comparison table shows the 520 consistantly less strong than the 525 http://www.didchain.com/chainSpecs.html
I snapped the chain on my Hyper 1100S last week - the standard DID chain with 22K miles on it. Weird thing was that I'd cleaned and lubed the night before and there were only a couple of tight spots that I wasn't too concerned about. I was also very lucky - no damage at all to the crank-case or surrounding, just a few nicks and a small chip off the rear carbon chain guard. I have replaced it with another 525 chain, but the ZVMX version at around £100 (DID 525ZVMX-104 in blue box) rather than the cheaper VX chain (in yellow box) and knowing what I know now, I wouldn't put a lighter/smaller chain on it! I also have 748 but the torque of the 1100 DS engine is much more than the 748, and makes it in a different way, so don't mess with stuff that could end up costing you a lot more!
Thanks again for the info, think ill stick with the 525 chain. Whats your thoughts on alloy rear sprockets on the Hyper?
It'll be fine....I'd get a hard anodised one tho. They do still wear quicker than steel but weigh nothing in comparison.
