So is it any good to build for any other class.
The only class it may work well in is Superstock / IMOW. The 420 engine is very robust and very reliable, Being low on displacement(420cc/26ci) it cannot compete with it's big brother, the 17hp Kawasaki FC540V long stroke thumper which is allowed in IMOW & GP. You will get stomped upon coming out of the turns or on re-starts. Plus, there are no aftermarket performance parts commercially available for the 420.
