Had a MRF tires when i bought my used 2015 street 750. the tires were 90% new and been using it for close to a year. due to limited choice of tires size for 750, finally got to change to Bridgestone, Exedra Max rear and H50 front. one can feel the grip on Bridgestone when taking corner, the confidence is great. during MRF, had near 2 missed slip when cornering. straight road no much diff but with passenger, the Bridgestone can feel the comfort, MRF its too hard.
But if Budget and limited choice (like in my case which took me a year to find other brand), than its just no other option.
