T6 is really good for motorcycles, I beat on my CBR1000RR really hard, it gets fresh T6 after every track day and every 2K miles on the street, motor is still strong and very healthy at 23K milesT6 is what I run in my bikes, really good stuff for the cost. My girlfriend misplaced her oil filter while riding, dumped all her oil, kept riding for about half a mile, and it was alright.
