So springs and emulators for the little Ninja drop into the little Honda?
That's almost too easy
I reckon Race Tech doesn't know this yet but hopefully soon will.
So I would assume the only R&D would be the shock. I've never taken a close enough look at the Ninja 250 to see how it was set up. But it makes sense that they both run 38mm forks considering they are similar in weight & power.
