I had the opportunity to do a demo ride at Daytona on an XB9R a few years back, and a friend of mine has an XB12R that I've ridden a few times.
My impression of both were that I loved the suspension, I loved the brakes, and I loved the looks.
All it needed to make it a great bike was to slap my TL motor in it.
The rev limiter kicked in at 5,000ish? Realliy? I know it's the engine design, but hell, I don't normally shift my TL until 7 or 8. Talk about shutting down the party way too early. I banged the rev limiter every time.
Fun bike. Needs a better motor.
