Hello first post but I've been following for almost year. I allways loved the looks a reputation of the Gen 1 since it came out and found a nice one late last year with 9K miles mostly stock with a slip on. It has the stock gearing which drives me crazy since I have owned mostly 600s. I'm about to go with a 16T front sproket and will use a OEM z1000 sproket. I'm going to try that first before changing out the rear and see how I like it. While I'm at it I might go ahead and replace the chain. I have used EK MVXZ in the past with good results. However, I've never owned a bike with this much power. Is this chain suitable for a stock ZX10r on the street with maybe a track day or two? or do I need the more expensive ZZZ model? I certainly don't want to crack my cases and or get stranded out somewhere.
