This contributes to mass centralization for nimble handling while also achieving a straight intake tract for superb combustion efficiency that delivers more power.??? The cylinder is offset so the connecting rod is vertical at the moment of greatest combustion force, minimizing piston friction against the cylinder wall that could rob power. That means quicker response.??? The 4-titanium valve cylinder head is matched to a newly recalibrated fuel injection system that provides superb low-to-mid-rpm power feeling.
