The Shay , Climax and Heisler locomotives, all introduced in the late 19th century, used quill drives to couple power from a centrally mounted multi-cylinder engine to each of the trucks supporting the engine. On each of these geared steam locomotives , one end of each drive shaft was coupled to the driven truck through a universal joint while the other end was powered by the crankshaft , transmission or another truck through a second universal joint. A quill drive also has the ability to slide lengthways, effectively varying its length. This is required to allow the bogies to rotate when passing a curve.
Our larger, longer riders really appreciated the space available on the VTX and 1500 Intruder, and the Suzuki offers a complaint ride. However, anyone under 5'10" felt both these bikes required too much of a stretch to be comfortable or instill confidence, and most everyone of every size felt the bar on the VTX was too wide. The LC also took top honor for the best stock seat, followed by the Road Star and the Classic FI. The Victory V92C offers one of the best riding positions in the group, but several people were annoyed by the bike's harsh suspension; it works well when you're riding the bike in fast corners, but really beats you up when you're just plugging along in normal situations.
Looking at box stock props, the Trophy is a good but the Pro Max should offer better overall performance and durability. The 8″ jack plate might offer a little better performance when you marry with the right prop. I think the Pro Max, with its tremendous cup wrapped around the blade tips, will give you what you’re looking for with the set back. The Trophy is ″ in diameter. The Pro Max is ″. The props share the same hub size. The Pro Max doesn’t have vent holes nor does it need them. There’s enough exhaust venting over the small hub. The plastic blow out ring fitted over the front of the Trophy would hurt the Pro Max’s planing performance. I think the Pro Max would be a fun prop for your set up.
