better rear brakes
Sat, 24 May 2003 00:09:45 -0700
Motorcycles come with cross drilled rotors primarily for weight reduction -
on these vehicles, there is not a lot of mass to slow so heat dissispation
is somewhat less of a concern. However, by lowering the rotational intertia
at each wheel, the bike accelerates and stops more quickly.
Also note that motorcycle rotors are typically very thin, low mass, and will
accumulate and dissipate heat at a much quicker rate than automotive rotors.
I find this an interesting comparison.
If drilled rotors are good for motorcycles, then why not use them on cars?
If vented rotors are good for cars, then why not use them on motorcycles?
