Well, the chronology is something like this:

1983: XLV 750
61 HP, 3 valves, aircooled, shaft drive. You don't see this unique bike very
often.

1986: NXR 750 Paris-Dakar racer. (Beautyful bike!)
780 cc (not 750), about 80 hp (?), 4 valves, water cooled, chain drive. It
won Paris-Dakar!

1990: XRV 750
61 HP, 3 valves, water cooled, chain drive.

So, it seems the XRV engine is a water cooled XLV with chain drive. No more
valves, no more power. I think it's very strange that we didn't get a street
version of the 4-valve NXR instead.

Keep sliding
