nice looking bike !
Wrenchmonkee style !
… it can’t be because of aquaplaning ;-)))
In Germany more than half of all twins have Bridgestone BT45.
I changed to them this year as well and they are very good under all conditions.
They are dual compound.
Hard, long lasting rubber in the middle and soft rubber at the sides.
I like that, it makes sense 😉
Max recommended tire size for the standard Bs are 100/90-19 front and 120/90-18 rear.
Of course they don’t have the rude attitude as your tires have in the moment.
