Those are possibly the most over engineered bike of the late 80's and early 90's.
Honda was smarting from their V4 debacle of the past 10 years. V4's were rubbing the lobes off their cams due to not enough oil circulation. The bikes would run great but get progressively weaker as the cam lobes ground down.
So they built this VFR.
Gear driven cams and tweaks everywhere else were the answer evidently.
GREAT bikes. They will run forever with some maintenance. They can be a bear to work on as the v4 config is great for balance and packaging but hard on non-japanese hands to get to.
INCREDIBLE SOUNDS from this motor. They positively howl.
Also, by today's standards, a very relaxed riding position.
It is rumored that Honda lost money on every VFR produced. They were so popular that dealerships would never offer a discount on them.
A modern classic.
