1982 Craig Vetter Fuel Economy Run
Date: July 10, 1982
Location: Highway 1 through big Sur See map
Route: San Luis Obispo to Monterey, California
Distance: 136 miles
Allotted time: 2 hours, 43 minutes
Round at the front, pointed at the rear: True streamlining
Dan Hanebrink and Bob Lebo were consistant competitors at the Craig Vetter Fuel Economy Contests. Their craftsmanship was superb. A series of minor mishaps kept them from winning top place. Here is Dan at speed at San Simeon. Note his foot sticking out by the rear wheel.

Dan went on to develop downhill racers.

Your winner,Charly Perethian.

Charlie came to work for me at Vetter right out of the Rhode Island School of Design. When I sold Vetter, Charlie co-founder Rifle Fairings with other, ex-Vetter employees.

Yamaha supplied the 185cc bike. Charlie put hours into .getting high mileage.

Charly designed and made this streamlined body from scratch for this contest. After the event, Charly loaned me his bike and I made templates from it so we could make an improved body.
Rifle Fairings vacuum-formed the new bodies which were made available to anybody who wanted to buy one.

It was such a good shape that every winner fron then on, used this body.

The Streamlined Body I offer on this web page is made from the same mold except today's bodies are lighter, fibreglass. Today's fibreglass bodies are easier to modify.

By comparing this to Charly's blue bike above, you can see where I refined and rounded out Charly's shapes to make it a better fairing. I figured that if I offered a good body, contestants could better send their time on the powerplant needs. Our Streamlined body of 1983 is as good today as it was then.
The best shape* for streamlining is round at the front and pointed at the rear

It will never change Demo Mov.

* I want to clarify this because some people find this hard to believe. The teardrop shape is the best shape to go through the wind up to about 600 mph. Above that speed, and into the 2,000 mph area, other shapes work.

The only thing that changes as we approach 600 mph is that the aspect ratio of the body. The faster you go, the longer the body needs to be. LSR ( Land Speed Record ) bodies have gotton longer and longer. Today, LSR machines operate in the 320 mph range and are over 20 feet long.

In the background: Hap Alzina's stubby Indian Arrow that went 135 mph in 1938.

The faster you go, the longer the body needs to be

Foreground: Burt Munro's much longer and faster Indian that went 183.586 mph in 1967.

24 feet long, 22” wide, 30” tall

350 mph at Bonneville Sept, 2006. Denis told me that his Cd is .08 and that it requires only 2.7 hp to go 100 mph.

Such is the value of small frontal area and streamlining.
