Thanks for the welcome. I too rode jap bikes from 16 on; Honda 90 sports, T200 Invader, TR350, XS650, Honda 750K2, GT750 Kettle, GS750, Z750 Shaft, CBR1000F, CBR600FR, VTR1000F, then the Triple Trio. After getting the same 4.5k mileage from several pairs of 01's on Sprint a 1050 ST and Tiger Sport 1050, it has to be down to me. (I only got 2,500 from BT50's on the CBR1,000 (2 rears to 1 front = 5k miles) I ran PR4's and 023's on the ST and got only 4k, when others on Tiger Sports told me thay got 8k from PR4's. Guess we all ride differently. I will fit a new rear and try for 1 front to 2 rears. Ride Safe DJ
