The guys over at Corbin are hard at work on a new seat and hard bags for Kawasaki’s ZX14. The manufacturers make the bikes and then it takes a little while before the aftermarket gets geared up with all of the things you need to make it more practical. The big Ninja should see a lot of high speed sport touring duty and Corbin makes a great line of seats and bags for most everything out there and it looks like the they’re almost ready to get the Ninja set up for your cross country work.
They expect the seat to be ready by late June and the bags soon after that. If you just parked a ZX14 in your garage, you might want to give Corbin a call.
