Fro 35+ years it was (2) wheels. No problem with stability. The gyroscopic effect on (2) wheels meant just a bit of lean got you thru the turn. Owing to cancer treatment in early '15 we had to go to a trike for stability. This '15 Tri Glide is a different handling animal. You can lean all you want BUT, if you don't steer you ain't gonna make the turn!!! I've learned from this forum that a rake will greatly improve steering/turning. QUESTION: why the heck doesn't Harley realize this and make modifications in the first place??!!..jimmer16
