Considering the Roadmachine RM01s focus on endurance and comfort, are there any inherent limitations to its customization potential that might prevent it from being tailored to meet the specific demands of a more aggressive riding style, such as that required in cat 4 racing? For instance, would modifications to the bikes geometry or component selection compromise its comfort-oriented design principles, or are there opportunities to strike a balance between performance and comfort? Furthermore, are there any specific component upgrades or swaps that could be made to enhance the RM01s responsiveness and handling without sacrificing its endurance capabilities?
