compared with modern bikes, they’re very crude, but still exciting to ride, they just need modern rubber.
For me, it was the riding position, the fact I kept catching my (very) large hands on the fairing and pushing it backwards was like trying to shove a super tanker. I just honestly didn't really like anything at all about it (except the looks) and found it very rider-unfriendly. Fast forward a few years and I've got an old ZX6R which is like night and day compared to the 'blade. The Kawasaki is not just a doddle to ride, but is also massively nicer in all departments.
That of course is just my opinion, nothing personal or whatever.
