I will be scared to drive those slow steep curvy downhills. Already ended up under the bike once in such environment. Luckily had steel boots and didn't feel the weight of the bike on my ankle much :)
We can take the highway and some tunnels instead! Way smoother and less stressful. No need to deal with those sketchy curves again, especially after that wild ride under the bike, glad the boots had your back or your ankle, really π What engine size is your Ninja?
