Re: The Suzuki TM-400 Cyclone
It was very fast, kind of heavy, had an erratic powerband, no flywheel, the frame flexed, bad headshake, was cheap to buy ($850.00 new in 1971), and looked just like Roger DeCosters GP bike.
Like so many fish, the public bought them by the boatload. Soon you started seeing things like this in the advertisement section of Cycle News:
"1971 TM400 Cyclone. Like new. Never raced. Injury forces sale $500.00."
A whole aftermarket industry built up around the Cyclone, in some vain attempt to make it rideable. Nothing short of a new frame, shocks, forks, and a 4 pound flywheel worked.
It came in number one, in the "Ten worst Dirt Bikes Ever Made" list.
Punch "Suzuki Cyclone" in your search engine, you'll see...
