What was the Kaio-ken?
It was the first time Raditz had heard of a technique like that. He had no idea what it was. It could actually increase Combat Power tenfold?
Son Goku gave him a simple explanation, saying it was a technique that instantly increased his strength, speed, and defense. At present, he could withstand a tenfold boost in power.

Compared to transforming into a Great Ape, it was naturally better to retain a humanoid form. Increasing one's power by more than ten times while maintaining a human shape... no wonder Kakarot did not care about the Great Ape transformation at all.
What Raditz did not know was that the maximum multiplier Son Goku could withstand was far more than ten. If it truly came down to risking his life, it was not impossible for him to unleash fifteen or even twenty times his power.
Raditz then turned his gaze to the side. After everyone learned Son Goku's Combat Power, they became curious about everyone else's as well.
The first to unleash his full strength and display his Combat Power was Yinsen, the only one capable of contending with Son Goku. Over all these years, Goku's rate of improvement had been astonishing. He had proven through his own performance that Yinsen's words about the Warrior Race, the Saiyans, were not made up. This guy's strength had risen far too quickly. He was definitely not an Earthling.
One companion after another had been surpassed by Goku. Tien Shinhan, who had once been roughly equal to him, had already been left far behind. Yet among this group, only Yinsen had never been surpassed by Goku.
No matter how astonishing Goku's performance was, Yinsen had always maintained a slight advantage.
They were all curious about just how strong Yinsen really was,
