I bought them after doing research My 2004 R1200GS is woefully low on torque to pull away from lights etc
Back in the day when I started the original rebuild of engine number one I had a thought about getting these and eventually I ordered a set and got them brought in from Australia
All the information that I had at the time pointed to better low-end torque which was exactly what I'm looking for If you want higher rpm higher BHP then you need to go for a hilltop tune
These for me were the solution I was looking for and it was a grade by everyone that I spoke to there was definitely an improvement in low end torque which meant less slipping of the expensive clutch mechanism
I hope in the next couple of months to be finishing off the new engine that arrived with crap valves after Gertie had a second valve drop when I missed a gear and the poor old engine had a catastrophic failure so much so it cracked and bent the piston and the conrod
