I have been forcing myself to go out in the damp on the GN125.
My experience since November:
Better/new tyres help confidence (psychologically more than physically I guess).
Diesel is everywhere.
Even big bikes take road naps sometimes.
Get consistent braking distance down to centimetres in the dry, and accept it is miles long in the wet.
Keeping loose is key.
Keeping loose is especially important when the rear decides to fishtail. Mostly learned this forgetting that my stopping distance needed to be miles not centimetres/diesel patches, and applying a tiny bit more rear brake than I wanted, since I wasn’t slowing down enough in the distance I had.
Still no offs so far and still enough wet days to come.
Saw a guy with his big bike on the side of the road in wet weather, having come off (not sure if crashed, crashed into, diesel etc). It still happens to the big bikes.
I actually quite liked riding with the roads totally flooded with water. Preferred it to that awkward rainy slippy thin layer.
