Before the CB I had a 919 that I changed the sprockets on. So sitting in the garage was a 17/43 set. After some research that seemed to point to compatibility, I broke out the tools.
It is a very quick change and not hard at all. I took reference measurements on chain tension, wheel alignment, Counter Shaft sprocket depth, etc prior and used this to insure everything bolted back together within spec.
Once I checked and rechecked the re-assembly it was time for a test ride. Let me tell you, THIS is the way it should have been built. The bike pulls very hard in all gears. At 55 the rpm is about 4000 in 5th so its very livable. Roll on in 5th results in a very rapid 70-75. A down shift results in a grin that can be seen outside the full face.
Well worth the effort. If you decide to do this just look for parts that fit the 2006 919.
