I was never really happy with the front fork on my BMW F800S.
It’s a 43mm Showa fork, and plenty strong for a 207 kg bike, but it’s clearly made to fit a budget, so damping is really poor, and internal friction is huge.
Not the best combination because you have little feel for the front end when braking into corners, and the bike is not stable in curves with uneven tarmac.
I tried to dump in a set of MUPO damper valves, but that just increased the internal friction. Lowering the front or changing the fork oil to a different weight did not provide any real improvements. I thought about fitting a Ôhlins upside down fork or similar, but it’s a major rebuild with new T-bridges, steering lock, Bars, Ingition key, Brakes, etc. And I couldn’t be sure the bars would clear the fairing or tank (That’s often a problem).
But I discovered that the Traxxion AK-20 cartridge dampers that could be installed in the original front fork. They are certainly not cheap, but every review I read was extremely positive.
So I pulled the trigger and after a few weeks this parcel arrived.
