Issue of space is even more so important for aforementioned cruiser big twins, because they tend to be a long stroke motors, while a lot of OHC engines sometimes have bore larger than the stroke, especially in big thumpers (600‒800 cc single cylinders such as Suzuki DR650 or smaller BMW dual-sports). | |

As I’ve read, manufacturers of motorcycles, for instance, use pushrod system on cruisers not only because it is a “classic” design, but also because the way they made, they produce a lot of low-RPM torque. However, this would not work for a high-RPM, high-powered sport-bike motor. | |
