The new Sports Tourer from Honda with variable-cylinder engine, which enables the rear bank of cylinders to shut down completely, leaving the bike effectively a parallel twin on light loads, which should dramatically boost fuel economy and emissions performance. This trend with Honda seems to continue from Cars to motorcycles these days. First time we came across variable-cylinder engine was with Honda Accord V6, now its Honda V4 Sports Tourer.
The frame reminiscent of the first ZZR1100’s vast girders – hints at what must be approaching 200bhp potential. Honda goes next with its new V4 platform, what else is special about that V5-derived engine and what it means for the Blackbird and Pan-European.
