that drawing is just wrong
it DOES show less trail for sidecar - but its completely wrong about how trail is developed - the diagram is wrong because its howing a line following the forks - what the line is supposed to show is a line through the steering bearing head. the trail is how far behind the steering head the tire touches the ground.
sheesh - bad info is worse than no info - the guy needed a editor to check it.

actually the diagram has the sidecar and solo wheels reversed, if the diagram is showing different tree's on the same bike. The sidecar wheel, kicked out farther with the new tree, would have less trail. It seems that diagram is totally reversed and wrong. The wheel on the left should be labeled "sidecar" and show "less" trail then the right wheel, which should be labeled "solo". It is drawn incorrectly, unless everything I learned is wrong,,,LOL,,,it could happen. See if this diagram helps
Trail is measured from the imaginary point on the ground where the (red) line thru the steering bearings and the ground intersect,,,rearward to the spot directly under the axle(contact of tire to ground) Remember, the intersection of the bearing line to the ground (red) DOES NOT CHANGE (for this discussion sake) after you install the angled triple tree.
This means the tire contact patch, moving forward,,gets closer to the intersection (red line and ground),,reducing trail.
Thank you gentlemen, and thanks for the graphic razerface!!!!
Now all these conversations I've been following concerning this issue are starting to make sense.
