Yeah it’s a Tomos brake shoe issue with wet roads
Nothing really to do with the most bikes that have have asbestos shoes on dry roads,
Riding in the rain everything locks up and skids, I know cause I had to commute with a moped or enduro motorcycle for several years in the snow and or rain you got to so careful it’s not funny,
In the winter blizzard 77-78 when I was riding a Italian moped I would just let the whole bike fall underneath me as I stood up at a stop, Way better than waiting hrs for a CTS Cleveland bus,
Though some days I had to take three buses to get from hi school to work and during the worst 77-78 blizzard the CTS bus broke down I had to walk almost 2 miles home with a 60 mph sideways wind and snow, my mustache and beard hairs were frozen with my snot, sweat and snow and ice!
If I wasn’t so young and I probably would’ve perished, I have a a few spots that are black on my face, neck and ears due to frostbite,
