All the hardware on my bike came with it. I reused the stock bolts for both levers. If you have a 2020 401, it might be like -373-Arrow said, they changed hardware to offset other changes. Or the previous owner swapped them to try and clean up the vertical slop.
Installed a 16 tooth front sprocket today. With all the performance mods done on the bike I still have plenty of acceleration, but now I can jam on the highway without pegging the rev limiter. Since I commute on the highway for a long distance, this makes the bike even more fun than it already was!
