Gregory Dunham from the USA has constructed the worlds tallest ride-able motorcycle that is 11’, 3” (3.429 m) tall to the top of handlebars, 20’ 4” (6.187 m) long and weighs 6,500 lb (2.948 tons). It is powered by a 502 cu in (8.2 litre) V8 engine and has tires that are 74 in (1.88 m) tall. This monster needs all 500Hp engine power yoked to 2-speed transmission to make it move. And move it does – Dunham claims the big boy will rumble to a terminal velocity of 65 mph (with an economy of 6 miles per gallon), which must be make for one hell of an interesting sensation.
Dunham built the bike over three years at a cost of $300,000. “After a while, I had to do something in life,” said Greg Dunham, adding ” I’ve always been an idea guy. “
Dunham steers it from a cage below the handlebars as it would be impossible to straddle the bike in a normal riding position. Technically he drives the bike rather than rides the bike.
“People love it” Dunham says. ” Fifteen guys came from out of nowhere to see it. One of the guys said, ‘Build me one!’ People love it! ”
Dunham started building the motorcycle he calls Dream Big.
It wasn’t easy. He twice had problems with the transmission that made him mad enough to want to set the bike on fire. Dunham collected the parts to build the bike from online shops and auto wrecking yards. He built the bike himself relying on the knowledge gained when he worked in car body and chassis repair at a garage.
