Well both machines feature much the same mods , so straight up , the more modern designed ZX14R is the better all round handling bike of the 2 , It can handle every type of road well , some very well , it feels overall more flickable and responsive to rider input on the power . Power wise , this bike feels 20 whp+ more than my Busa , feels lighter than the Busa , but actually may not be quite as light .
The Busa , before I changed the recent ride position , was also good on all roads , very good on fast flowing roads . It was heavy on steering in tight corner roads , but competently handle these roads well enough too .
The recent changes I have made , and including the 47t gearing , has opened up a new dimension of ride ability for me , the Busa now really shines in tighter corners , with medium speed flowing turns the best fun I have ever experienced on any bike . The bar setup now allows great turn in ability and I can easily , really make it stick to any chosen line . It is still has that heavy rock solid planted feel , but the wide bars now enable astounding flickability . The Busa now definitely has the edge over the ZX14R on this type of road , and will certainly hold its own in the 160kph + roads . I suspect only to ever lose sight of the Kawasaki if the country opens up to 200 kph + roads , not only to lose a bit here because of gearing and aero changes I made , the Zed14 is just outright faster here .
The Busa with said changes is now the most comfortable to ride , I want to ride it all the time . The Zed14 is still very comfortable , and was the best before the Busa change up .
