I used Road Smarts long time ago on a 94 VFR. On that bike they were fantastic rubber. I feel the same about Shinko I think they are total crap. Slippery with no feel, but I do ride my 12 like it was meant to be an maybe if your just cruising around a city they work fine. Your rubber is all that’s keeping your ass off the pavement, we all have our own preferences of brand/size but overall I think tires are an absolute terrible area to go cheap. Save elsewhere an put a decent set of rubber on front and back. Your riding a ZX12R a serious machine not some 40hp CBR300. Be smart about it.
