I am someone who lives in a very flat area, not a single hill. Suppose I was taking a road trip and had to go up and down some mountains, what tips should I consider to be safe? How do I avoid ruining my clutch or my breaks?
It’s a fair question and you don’t say what your bike is so it’s hard to answer, but in general your (relatively modern) bike is tougher than you think and it will be fine. I’d say practise your slow speed and tight turns in a car park - that will help going up. Coming down, use engine and both brakes to slow before the corner - take it easy (especially if it’s damp/cold) and you will enjoy it. And you will be fine. Source: rides in mountains sometimes.
