In this 8th episode of Wheels Camera Action, we discussed on the age-old debate between SOHC (Single Overhead Camshaft) and DOHC (Dual Overhead Camshaft) engines. Rather than declaring one superior, we explore their respective strengths and how they cater to different needs in the motorcycle world.
Power and Efficiency: DOHC engines often deliver more power thanks to their ability to manage valve timing and accommodate more valves per cylinder, especially at higher RPMs.
Complexity and Cost: While DOHC engines boast higher performance potential, they come with added complexity and manufacturing costs due to extra camshafts and components. SOHC engines, on the other hand, are simpler to build and maintain, translating to lower production costs.
Engine Size and Configuration: SOHC engines are favoured for smaller displacement engines or where space is limited, as they require fewer parts and take up less room. DOHC engines shine in larger, high-performance setups where maximizing airflow and power is crucial.
Maintenance and Serviceability: SOHC engines often win in terms of ease and affordability of maintenance, requiring less frequent adjustments compared to their DOHC counterparts.
Application Specifics: Regarding motorcycles, the choice between SOHC and DOHC depends on the intended use. Racing bikes and high-performance models might opt for DOHC for its superior power and efficiency. In contrast, commuter bikes or entry-level models may lean towards the simplicity and cost-effectiveness of SOHC engines.
