Decided it was time for new sprockets and chain. 15k not high but they started to look worn so off they went. Was gonna go ZZZ but then saw this 3d chain from EK that came out recently. Wow! What a chain! Supple, transfers powers effortlessly. Reduced the engine vibration considerably. Bling factor is high with a polished gold links. Bike feels amazing on it. I'm in love :
