I'm back to give another ownership experience update on my 2019 R1250GS. I have just over 15,000 miles on her and not a lick of trouble.
Will need new tires in about another 1000 miles. I have the bike 3 years now and still think its the best ADV bike out there.
Yes, more expensive initial cost when compared to a new S10 but such an amazing bike.
The service costs have not been too expensive (IMO), minor service $250 (every 6500 miles), major service (every 12,500 miles) $1200. I ride about 5000 miles a year on the GS but also have a 2017 Goldwing that I put around another 2000 miles on per year.
Have fun and ride safe!
