I have. I only have one yr of experience using the MotoBatt product. You can't miss them with the BRIGHT YELLOW color. I bought one for the Hayabusa last year because I didn't want to spend the money on a LiFePO4 or race battery, but the MotoBatt was the only brand I found that offered a TWO-year warranty vs. the one year for AGM batteries everywhere else. And, it was the same price as other AGM batteries, so I gave it a shot. Anecdotally, I got a trickle charger as an Xmas gift, so I put my old SV battery on it, and it took a good 3-4 days before the trickle charger went "green" (charged). When I swapped and put it on the Motobatt, it went green after a half-hour. I continued doing the swap all winter with similar results. So, for using the Motobatt for half-a-season last year, it still holds a good charge. The Hayabusa fired right up today when I reinstalled it... so far, it seems to be a good product.
