How Come Cars Street Can't Redline Nearly As High As Some Street Motorcycles?

I have a few buddies with Japanese cars that can go abouts 8K RPM or so. I have a Japanese sport bike that redlines at 17,000 RPM which doesn't really have full power until it reaches 10K and up.

Having both be Japanese, why is that bikes can have such a higher redline than cars and actually be able to handle it like it's normal?

I hear that taking a car really past 5K isn't that good due to it putting stress on the engine. Well, on my bike, I take it up pretty high and 30K miles later, valves checked out dead on spec and compression is still perfect from day 1.

What is really the reason? Smaller size, or how they are designed? Curious about this. Thanks
 
how they r designed......car motor generates more power at lower rpm cas u need lots more torque to get a 5k lb vehicle moving.....bike is designed for speed... dont need as much torque to get 800lb movin
