...First, what made you decide on this bike?...
I had a KLR650 AND a Bandit 1200S, had just read the article in MOTORCYCLIST (2008) where they declared the Versys as MOTY, so I took a look at one at my dealer. He walked up, handed me the keys to their 2007 'tangerine' Versys, told me to go for a LONG ride and to "wring-its-neck", which I did. I came back about an hour later, VERY impressed.
I had towed my KLR to AZ each winter since '03, then made the decision to order an '08 to pick up in September when we went down.
...Second question, what mods have you had to do to make it comfortable for you?...
Back in '08 raising the front of the seat was a very wide-spread mod, so it was my FIRST. I also ordered a set of foot-peg lowering blocks from motowerk, and ZETA XC handguards plus H-B crash-bars (which I later changed to SW-Motech to go w/ an SW-M skid-plate), then went to Aprilia Tuono mirrors.
...Third question if you had to do it over would you buy this bike again if not why?...
I bought a "left-over" '09 (the GREEN HORNET) in Nov '10 to import into Canada (c/w the SAME mods!!!), and when it was an insurance 'write-off' at 62,790 kms in '15, I replaced it w/ a '15 650LT (the GREEN HORNET TOO), which has 51,620 kms now. (That totals 114,410 kms, or 71,091 MILES, and added to my '08 mileage of 76,xxx miles, means I've ridden OVER 147,000 miles on Vs, so I guess you could say that I 'like' them...!
...The next question I have for now is how expensive are the parts to repair compared to say BMW or other bikes. Finally, how often do you have problems with the bike's engine or transmission?...
WAY-Y-Y cheaper than are BMW parts, and really haven't needed many, and the 'engine and trans' have been basically problem free.
Try it, you'll LIKE it...!
