Bought my 1600 and after a month of around town break in rides, rode from Venice, CA up to Canada and across to Montreal, down to Hartford CN and then back to CA along mostly interstates, a 10,000 mile ride…..and it was VERY uncomfortable on the stock BMW seat. All you have to do is set on one and you’ll understand or ride one for 200 miles and you’ll really understand! So, found Rocky (Bill Mayer Saddles) on the internet, read reviews and called Rocky for initial conversation and scheduled appointment right on the spot. Rode up from Venice and had a custom fit seat that afternoon! Took two local test rides with seat modeled up per my input and then they completed the seat and off i went. I can’t tell you how much more comfortable it is now to ride…..I can ride all day in my Mayer saddle and often do. Have taken another cross country ride that was SO much more comfortable and just rode to Colorado where I met a buddy who rode from MI. We met in Boulder and rode all thru CO and UT before we split up and went our different ways; it was a 3500 mile ride in complete comfort! Thank you Rocky, much appreciated.
