I don't think the original poster has been back in about 8 months.

The above IS a good point BUT.....bikes are still being built that make good power with ~ 750 CCs. An I-4 or V-4 with "small" displacement will easily keep up with an 1800 CC behemouth.......you usually just have to shift an extra gear or two to do it.
