When friends and family ask me how long I've been with
Cycle World, I don't say, “Since the debut of the Harley-Davidson Dyna
platform.”
But I could.
Although Harley claims that the Dyna family can be traced back
to the first factory custom, the 1971 FX Super Glide, the actual platform, with
its reconfigured frame and vibration-quelling, engine-isolation system, debuted
with the 1991 FXDB Dyna Glide Sturgis.
It was the first Harley created with Computer Aided Design,
and with its pair of composite rubber-and-steel engine mounts (two fewer than
were used on then-current FXRs), set a new standard for smooth.
“At idle,” noted our October, 1990, road test of the
monochrome machine, “when the engine's power pulses are at their most violent,
some booms and throbs make it all the way to the footpegs, seat and handlebar,
but they hardly are annoying—in fact, they make for a rather pleasant sensation.
And once the revs climb above 2000 rpm, the shakes and quakes are all but
eliminated.”
I was reminded of this as I tooled toward Long Beach on
Pacific Coast Highway aboard the solo-only Street Bob, a factory homage to
bob-jobs of the past and one of six Dynas in The Motor Company's lineup for
2006. The carbureted, 1340cc Evolution V-Twin that powered the Sturgis has long
since given way to the fuel-injected, 1450cc Twin Cam 88, further refined this
year with a host of internal improvements, but, overall, the on-the-road
experience is much the same.
Startup is immediate, and the black-powdercoated engine
(matching the console, battery box and belt guard) settles almost as quickly
into an even idle. Regardless of rpm, throttle response is hiccup-free. Output
is sufficient for getting away first from stoplights but never intimidating.
This is a most pleasant and charismatic powerplant.
Right up there with the engine in terms of
user-friendliness—if not spiritual presence—are the new six-speed Cruise Drive
transmission and easy-squeeze clutch. The first-gear “clunk” remains, as Harley
intended, and the throws are positive. I never missed a shift.
This one might take you back to the middle of the
century when riders looking for a little extra speed and a unique custom look on
a Harley® started stripping off the shiny parts. Check out the raked front end,
solo seat and Black Denim paint option. Now get ready to put two fists in the
wind, courtesy of factory ape hangers framing the road ahead. The emblem on the
Fat Bob™ tank looks like it was carved from a block of solid metal. Laced
wheels. Black powder-coated, polished Twin Cam 88® powertrain. And the new
6-speed Cruise Drive™ transmission via mid-mount controls. Kick it into gear and
you’re riding clean and pure. It’s just what the open road calls for.
OVERVIEW
FXDBI Dyna Street Bob™ Model Overview
The new FXDBI Street Bob takes minimalist styling to a new extreme. Inspired by
the post-World War II "bobber" movement, the Street Bob discards any component
not required by law ... a passenger seat and pegs, for example. A solo seat sets
the tone for a motorcycle designed for the individualist. Seat height is just
25.8 inches. Mini ape-hanger handlebars, the classic Fat Bob fuel tank, a new
wrap-around rear fender and steel laced wheels complete a profile that will
stand out in the cruiser crowd. A new wrinkle-black finish is applied to the
battery box, console and belt guard. Four color choices include new Black Denim,
a flat-black finish.
