The veering test is pretty simple, get on a straight line or freeway, lock the cruise control on 70-75mph, seat straight and safely take your hands off the handle bar and start counting from 1001 to 1010, if you end up in the guardrail or the shoulder your bike is veering!
I highly doubt that BMW would spend extra time and money to address something idiosyncratic, my guess is it’s more than that, but who am I to know.
Anyways regardless of the outcome I am already satisfied and happy to know they were not ignorant and tried to address an issue that concerned many riders.
There was one video presented already that Josef addressed the veering issue of the K46. He tried to explain that the K46 engine was placed slightly off center to the right side of the frame for weight distribution. Now with the engine offset, and the stock headers and muffler on there, it just added too much right side weight.
Josef went on to explain this was taken into consideration with the design of the K67 and the engine is more center line based with better weight distribution.
For those that have added full exhaust to the K46, and other weight balance taken into consideration, you can get a K46 to track 100% straight for miles upon miles. Both my 15 and 18 now are balanced enough that I can set the cruise on open road and sit up with my arms resting on the tank or crossed, and go for miles. Change of lanes can be made with the simple weight shift on the seat and pegs.
So if the K67 comes out of the factory totally balanced this will be a nice feature upgrade. However, if you put a lighter full exhaust on there, and lighter muffler, it might now create the veer to the left, instead of the right.
Just to illustrate the engine in the K46 in the 'offset' to the right Josef was referring too. I just happened to have a K46 engine and frame sitting in the shop right after I saw that video. I took this picture and I draw some lines ( very crude lines at that ) showing how much valve cover is to the right side compared to the left. Its just the way they wrapped the frame around the engine that makes the offset so pronounced.
