Zongshen RC3

Looking at Motorcycle.com's dyno graph has me pondering the RC3's tuning. While a dyno on different days will provide a different result (and different types of dyno generate different results), typically the peak power and torque occurs at relatively the same RPM. But on the RC3, I'm seeing that peak HP occurs at 7,800 rpm, whereas the RX3 makes peak power at 9,000 rpm. And peak torque occurs at 6,000 rpm on the RC3 versus the RX3's 7,000 rpm. I wonder if this is due to tuning, the exhaust, or something else? But based upon the dyno session with my RX3, the power output compares very favorably to the CBR250R's output.
