Sprint gearboxes like the engines take a bit of breaking in.
It is normal for a Sprint's g'box to require a very positive boot especially when new, they can be quite tight while breaking in.
They all get better with more miles, it is certainly not a "Gixxer slick" box but it isn't bad either.
I call it character!
I guess that's what the Ducatisti call their noisy rattling dry clutches! :razz:
