I want a bike that feels stable and predictable, especially in traffic and on highways. During inspection, I check the steering movement, front forks, rear suspension, and tire wear. If the bike feels wobbly or the suspension is too soft or too stiff, I know I may need to budget for repairs.
Brakes and Safety
I never ignore the brakes. I test the front and rear brake response, inspect the brake pads, and look at the condition of the discs. Good stopping power is important to me because it adds confidence and safety. I also make sure the ABS, if fitted on a specific unit, works properly.
