I brought my bike in march 16 by private sale. It is an 07 ST1300 with 22000km on it. Soon after getting iy i replaced the tyres with pirelli angel gt, and have had steering wobble issues ever since. I managed to resolve some of if by following the tightening sequence written elsewhere in this forum, however still experienced slight wobble while decelerating between 80 and 60 kmh. I put new tires on last week and followed the same tightening sequence. I have a worse wobble than previous, and I can feel it through all gears and worse while decelerating. Balancing is ok. Does anyone have any suggestions as to what the issue might be.
