Triumph Bonneville Supermoto 'Trouble'

1 of 3

A Hinckley Triumph Bonneville isn’t the most obvious of starting points for building a supermoto but when the finished product looks as sensational as this Californian built special you have to admit it’s worth the trouble.
Posted onto the Advrider forum ( by the current owner, the 790cc Bonneville motor and swing arm are the only stock items on the bike.

The frame is custom TIG welded 4139 Chomemoly, forks are from a Kawasaki KX500 and shock off a CR500.

The fuel tank is a hand formed alloy one-off but the seat and plastics appear to be aftermarket enduro parts.

It’s believed the bike was originally built by the owner of a bodyshop and fabrication business in Paradise, California.
