The Speed Triple has been a commercial success for two decades, but between 2002-2006 it had an inline 4 cylinder brother, the Triumph Speed Four. The naked variant of the TT600 sport bike, the Speed Four had the fuel injection problems fixed. The 599cc engine yielded 97 horsepower, good for a top speed of 155 mph and a 3.5 second 0-60 time thanks to the 375 pound dry weight. At the time, it was hailed as a wonderfully handling bike. In fact, even in 2008 the Speed Four was deemed the best handling motorcycle in the RiDER Power survey. Find this Speed Four for sale here on Craigslist in Lower Bucks, Pennsylvania for $4,450.
