I'm looking for tires for an upcoming trip to Colorado where we'll be doing some trail riding. Of course finding adventure style 50/50 type tires for 17" wheels isn't easy. I already run a 150/70/17 rear and have had no issues with that but wondering about the front. I'm seeing a lot of people mention the 130/80/17 but I'm not clear if that requires a fender modification or if that size will fit as is. Anyone with experience that can shed some light and possibly a tire recommendation? I'd like to avoid modifying the fender. I have a '17 650. Thanks.
