What is the difference between high-revving and low-revving motorcycle engines?

[AdalynnFitz]

High-revving and low-revving engines differ in advantages, construction, fuel consumption, and power output. Different advantages: High-revving engines enable faster vehicle speeds. Low-revving engines provide greater engine torque. Different constructions: High-revving engines use a high-speed chain system for timing mechanism transmission. Low-revving engines employ a pushrod system for timing mechanism transmission. Different fuel consumption: High-revving engines have a higher fuel-air ratio, making them more fuel-efficient. Low-revving engines have a smaller fuel-air ratio, consuming more fuel. Different power characteristics: High-revving engines focus on power output, featuring higher maximum RPM and quicker acceleration, making them more suitable for medium-to-high speed riding. Low-revving engines emphasize low-end torque, with relatively lower maximum RPM and slower acceleration, making them better suited for steady cruising.
