Ya all around quality chain i have KTM RC390 & DUKE390 these small street bikes really benefit from this kind of high quality light weight standard style (meaning theirs no rubber O-Rings)chain 1.89lbs less slinging weight on your bike than the original chain. Oil every 70-100 miles with your used synthedic mixed with a little gearlube and it'll last long.
WAS VERY EASY TO INSTALL, AS ALL WOULD BE. SLIGHTLY DIFFERENT FROM STOCK, WHICH WAS A CONCERN, BUT A QUICK CALL TO RK CALMED MY FEARS. Only have 350 miles on the new sprockets and chain, so I can't attest to durability.
Gave 5 stars because easy install, good quality, and does what it says it will do. Anyone thinking of buying this will need to take note that this will decrease your mpg (decreased mine about 5 mpg, I ride hard) and you will need to adjust your speedometer accordingly. Again great product. If you are looking for a faster acceleration this is your product.
