Anybody purchased one of these? I'm needing a new setup this Spring and though I'm not necessarily looking for the conversion (more keeping the stock setup) I was just wondering if anyone had had any first hand knowledge of them. Just seems easier to me to buy everything together, rather than separate, but sometimes quality can be sacrificed in those cases.
For street use and for long term reliability and durability, stick with the stock size chain - the 520 probably will not last as long, may need more frequent adjustments and while they may offer some slight advantage on the track, not enough to justify it for street use.
That's my nickles worth
Oh, if you are replacing sprockets, the 17 tooth front is a n ice addition. Corrects the speedometer, smooths the machine noticable at highway speeds, it's AOK in my book.
It also corrects the issue with the chain being too long - I actually replaced a couple chains under warranty (with low miles) when there was not enough adjustment left.
Tried a 15 tooth, did not like it much - great for wheelies, that was about it.
I just pulled this set up off my bike. It was on the bike when purchased at 21k and now that I'm over 30k. The items I have look the exact same as what's pictures in the ebay page. I've had no issues with the set up, but I can see plenty of wear on the rear sprocket. I don't know when the items were installed on my bike, but I really have no complaints about them.
I'm going back to 530 (I didn't even know the chain on the bike was less then this until I pulled it off and compared it to my new chain) and JT steel sprockets.
