I'm a new R1250 GSA owner. Bought in June, and have now crossed from one side of the country to the other. I took two training courses at the BMW performance center in Spartanburg, SC: 1 day on-road and 1 day off-road. Great courses, and they helped me understand how the bike performs. I gained a lot of confidence on road, but in certain ways lost some confidence in my off-road abilities. I spent a few days in Badlands National Park, and took the bike on my first ride on a gravel road. This was a groomed road in a National park, and they put endless washboards on the road, I guess to help with water drainage? The bike felt very squirrely on those washboards. The rear tire kept wanting to get away from me. This is the biggest bike I've ever ridden off-road. So my question is, what suggestions do you have for helping me get my confidence? BTW, I still have the stock 90/10 tires on the bike. I assume the bike will do appreciably better with knobbies on it. But for now, the vast majority of my riding will be on roads...till I get to Guatemala.
