It was 0…+1 C in the morning and I had my first ride on icy streets.
The streets close to my home had really slippery ice in the intersections. I stopped and checked with my boot. Very slippery. The spikes on the bike worked very well, the tires did not slide at all, even when braking to a stop. Main roads and city streets did not have ice.
The road back in the evening was easier, temperature was still low at 0…+1 C, but there was no ice left.
After the bike had cooled I rinsed it with a hose to remove salt, if any.
I shopped for motorcycle oils today and decided to use 5W-40 oil, to protect the engine on cold starts. I expect lowest temperatures to be down to -20…-30 C.
