As far as wet riding, both Wendy and I have ridden through torrential downpours and neither one of our Triumphs missed a beat. Rode from here to the northern end of Vermont in heavy rains the whole way and the friend I was with also rode a BA and none of them missed a beat. Why a very few have wet weather issues I have no idea but it is for sure the exception rather than the rule.
I learned all I need to know about life by killing smart people and eating their brains. Eat right ,Exercise ,Stay fit, Die Anyway!
