Yeah, they aren’t great value if you just want big numbers.
A modded Busa will always win, drags, dyno etc etc.
They are a very good streetbike that offered a level of trim and spec you can’t add to a Busa. I like the toys and extras and fancied a change. I think I’d still be happy if I’d bought a Gen-2 and I’m actually still after one for the drags. I don’t think they are a better bike, just an alternative that ticks different box’s.
I felt the same way with my Kawasaki especially after selling my last ‘standard’. The Z900RS really hits the buttons the Busa doesn’t on the mountain roads around here. I wonder what parts it shares with yours.
