Power 5 has been around for a couple years now, I've been running them since last year and love the performance for street riding as I mostly ride on street, they are very confidence inspiring much more than the stock metzlers my 2018 came with from the factory. Most places will have power 5 in stock, accoridng to the cycle gear store in my area in NJ they said the power 5 is the most popular sportbike tire right now.
