Hello netriders, I hope you can help me with a current chronic discussion (argument really) that is occuring in my home. I have been looking to upgrade the bike having nearly done my year of penance on the 250. I was thinking along the lines of a 600hornet or bandit cbr etc. He ( a Bonnie fan to the end) says if I don't ride them to their max it will cause damage to their engine disigned for high performance and that I should therefore buy a Bonnie that is designed for low km torque usage (hope I have that right) for the daily city commuting that I do. So I say, why do we buy cars that can go way over that speed that we legally drive them at and it doesn't damage them, he retorts that they are made to cope with driving them slower. Now my questions are.... does that make any sense? Please help me understand why I need to ride a sports/tourer bike at 200km/hr+ or risk damaging it or is it a .....um.... a ...... well you can fill that in. Look forward to hearing any opinions.
