No necessarily the best bike, but the one you've had the most fun on?
Tough one for me as I've had a lot of bikes over the last 10 years. The 675 was a laugh but I didn't have it for long. The Versys 650 has been pretty surprising. Mixed feelings about both zxz6r's

I think I'll go with the z1000sx. A proper all rounder that did me proud for work, touring and on the back roads.
