The RSW Vs the RSA is not even a close apples for apples comparison regarding the physical layout and many other detail changes - I have serious difficulties attributing
the RSA power increase to simply 25cc of CCR = going from 1.238 to 1.227 = only 8/10ths of 1 % change.
That % would be 0.4 Hp in 54, sure, absolutely worth doing, along with at least 5 other changes with far more significance.
But the RSA had its own downsides - the rear valves gear drive, and the front mounted bent pipe that also negatively affected the bikes weight balance and thus its handling.
Jan has said that given the opportunity to do it again, he would far rather have a valve on each side, not one on the back.

The Dutch are at 20RWHP with their 50's. This is where we are at now. Not even the best for NZ but we are working on it.



This is someone else's but essentially the same motor as I am building. Hopefully with some direction from EngineMod2T we can do a bit better with our Rotary Valve Suzuki RG50 motors.
