OK not V4 related, but still buttstop so I thought you guys would like to see this.
My buddy who designed my buttstop for the V4 (best mod I ever did on the bike) now designed and printed one for my Kramers. The extra nuance in Kramer is gas tank fill port so he came up with a cool design. Testing on track tomorrow and tweaking the size.
OK, here's an update. I recently switched from street bodywork to full race bodywork on the V4 and the tail is different. This was an opportunity to evolve/refine the backstop. The fabricator who did the original took on the project and here is what he came up with. The mount is billet aluminum and the backstop slabs are 3D printed, like before. A base plate and a few 1/2" and 1" slabs to adjust for rider butt size. I plan to add some seat foam/felt material to it once I fine tune stack height.
