Made a mistake buying tires for my 2009 Kawisaki ER6n today. The stock front size is supposed to be a 120-70/17 and I boneheadedly bought a 120-60/17. Will the lower profile tire on the front have a negative impact on handling? I do ride somewhat aggressively, but not like a complete idiot (most of the time), so I want to make sure it's going to handle right. The shop I bought it from is a pain in the ass when it comes to returns/exchanges so I'd rather not have to mess with exchanging, but if the different tire size is going to jack up the ride I'll put my boxing gloves on and deal with the shop. Thoughts?
