Ducati 749
Encyclopedia
The Ducati 749 is a 90-degree L Twin Desmodromic valve
actuated engine sport bike built by Ducati Motor Holding
between 2003 and 2006. Designed by Pierre Terblanche
, the 749 was available as the 749, 749 Dark, 749S, and 749R. It shared many of its parts with the 999
, with the exception of a slightly smaller 180/55 profile rear tire, smaller cylinders, and different cylinder heads, giving it a smaller displacement of 748 cc. This smaller engine is higher revving and produces a lower peak horsepower than the larger engine used in the 999. The 749S model, like the 999, incorporates features rarely found on production motorcycles, including adjustable rake (23.5° or 24.5°) and five-position adjustable rearset mounts.
A limited number of the 749 were manufactured as a race version — the 749R — each with their production number stamped on the triple clamp. This race model was lighter, had a shorter stroke, increased bore and larger valves which allowed it to run more efficiently at higher RPM, and hence, produced more torque and power than the 749/S models. The 749R also came with a larger tank (4.8 US gallons); slipper clutch; Öhlins
forks, shock and steering damper; racing cams; titanium valves, valve guides, and connecting rods; magnesium head covers, and carbon fiber belt covers. Its 2004 model had carbon fiber fairings.
The 749 was replaced by the Ducati 848
for the 2008 model year.
