I actually read part of the manual that came with new to me Husky 510SMR. Manual states that bike is not meant for longer rides. For you riders with experience with this bike, what do they consider long rides? As long as I'm riding 55-60 mph how long/far can I ride before stopping for this one lunger to breathe? I'm older rider that normally don't even start a bike up for less than 100 miles. If it's not meant to ride over 15-20 miles at the time, I'll just ride something else.
