Yo, I'm a fan of Bridgestone tires. I've used these from the street/touring to several Trackdays on my bikes! BT-023, T30, T30 EVOs, S20, S21, S22s on my 650R and lately the RS10's on my ZX6R! I've bought my tires from this place the last several years. Never once fucked up my order, etc. I think their the cheapest price unless a place is going to match their price. Dunno dont care, I've been happy with my purchases from these guys: https://www.rockymountainatvmc.com/ Going into 2021 season I'm curious to try out Pirelli. Those new "TD" tires look insteresting. N2 trackdays were sponsored by Pirelli, but for 2021 they've changed over to Dunlop! I looked around and not many places sell the Pirelli "TD" tires. You can try Moto-D https://www.motodracing.com/pirelli or I might try buying Pirelli's from these guys: https://tracksidetires.com/
