Just to add:ShadowDave said:Here are some distinctions on which Shadows and some other Hondas are single or dual crankpin.
I have noticed some publications have conflicting information between dual and single crankpin, but let me know if anyone notices any corrections:
1983-1988 Shadow 750, 700 & 800 dual crankpins
Shadow 600 I think single crankpin
1985-86 Shadow 1100 dual crankpin
1987-1996 VT1100C dual crankpin
Shadow 1100 ACE single crankpin
Shadow 1100 C3 1998-2000 single crankpin
Shadow 1100 C3 2001-2002 dual crankpin
Shadow 1100 Spirit (1997-2006)dual crankpin
Shadow 1100 ACE Touring dual crankpin
late model 750s I think these are all single pin
VTX 1300 single crankpin
VTX 1800 dual crankpin
You will notice that the only Honda 1100 Shadows that were single crank pin were the 1100 ACE (1995-?) and the 1998-2000 C3 (I believe the C3 was the Aero).
The Aero 750 and new Spirit 750 (VT750C2) are single pin.late model 750s I think these are all single pin
From what I have read, the following articles report both of these bikes as single pin. Of course any article on the internet could be suspect :wink:The Aero 750 and new Spirit 750 (VT750C2) are dual pin.
The following Motorcycle USA test on a 2004 750 Aero:Of course, all the essential goodness of the original Spirit 750 remains. At its heart beats a 745cc liquid-cooled 52-degree V-twin with a bore and stroke of 79mm x 76mm. Both connecting rods are bolted to the same crankpin, delivering the rumbling cadence and torque that so many riders especially seek out.
I'd think at least the Honda News article should be accurate. To be totally technical, I believe that some engines technically have two separate crankpins, but if they are in the same alignment and not offset, some articles describe them as single crank pin since they have the single crank pin characteristics of sound and power.The powerplant is a 52-degree, liquid-cooled V-Twin, single overhead cam with two spark plugs and three valves per cylinder. It uses a single-pin crank so you get the familiar V-Twin beat, and a single 34mm constant-velocity Keihin carb to mix the fuel, and allow for easy adjustments.
ShadowDave provided a list of Shadow models and their respective engines. The subsequent replies were additions/corrections to that list.cycleheart1100c said:Those articles are about the 750. The original post was regarding the 1100 spirit.
