I don't call this a downside! You can run Sport touring tires and its like having Supecorsas anywhere else. Ive managed 62° lean angle on the S21's, stopped the bike mid-turn, gotten off, finished my coffee, got back not the bike and finished the turn. Sticky for daeaaaays!The only downside is the road surface is very abrasive. Excellent grip on Arkansas roads but they eat tires at roughly twice the rate I otherwise experience (anyone know why/what they use?). But this also means great traction and and you can use a "lesser" tire with better wear and never worry about grip.
