Come on Mike, it was the 70s. It was the time of Disco music, polyester bell bottomed leisure suits, and a mild dose of exaggeration in the days of salesmanship.
Perhaps you can chalk ...some ...of it up to flywheel hp compared to RWHP🤔
Regardless of the big claims, it’s hard to argue that with regard to cb750s they did basically dominate the record books for drag racing during that time period. From the Pro Stock to Top Gas to Top Fuel they broke more records(usually their own) than anyone else in the engine type.
The standard cobra motor advertised at RC certainly didn’t put out 130 RWHP, not even at the crank. But I still have a healthy amount of respect for their innovation and successes. And boy did they break s#!t along the way...😉
