Todd picked up another Honda - this one is a 1986 VF1000R.
First available in Europe, then brought to the US in 1985.


From
motorcycleclassics.comThe VF1000RThe V4 line’s flagship model, at least in its pedigree, was the VF1000R. Derived from Honda’s AMA Formula 1-winning FWS1000 race bike, the R used the FWS’s gear-driven camshaft arrangement.
The VF1000R arrived at U.S. dealers for the 1985 sales season with just a few listed changes from the European model. The Euro-bike’s twin headlights were replaced with a single unit; the seat cowl design was revised; and there were mandated changes to switchgear and instruments. The R was easily differentiated from the F model by its full fairing, replacing the F’s handlebar-only item.
The main differences from the F model were inside the engine: compression ratio was up from 10:1 to 10.7:1; more radical cams with longer exhaust duration; and a train of nine gears to drive the camshafts, replacing the central chain drive used on the other V4s. Effectively, the VF1000R was a homologation special, built, initially at least, to qualify the bike for production racing.
Though Honda had used gear-drive cam operation in race engines, this was the first of Honda’s road bikes to be so equipped. Gear drive typically offers more precise and less variable cam timing at the expense of noise, weight and cost.
