Can any one tell me what the trail is on a gl1500 trike with a Ezi steer 4 degree rake kit
And is the 4 degrees taken from [LEFT][COLOR=#222222][FONT=Verdana]the original top yoke to calculate the trail or the lower one[/FONT][/COLOR][/LEFT]
The standard setup for a bike is 30 degree rake with a 111mm trail
Not sure if this helps!

Hi Thanks. I have already got this saved.
I'm not sure I understand your question but, I would say the bottom tree. If you start moving the top tree much you'll usually start having clearance problems. Some bikes experience clearance issues anyway.
[B]Hope it helps. [/B] You could ... fairly easily I think ... pull some lines and measure trail on a level floor. Pull a string along steering stem axis to floor on level surface, then drop or hang plumb bob against axle, measure on floor the difference.

[/QUOTE]Not sure that's exact on a stock GL1500, maybe … but I would say close anyway. The standard set up for a[B] [COLOR=#0000cd]BIKE[/COLOR] [/B]is not necessarily great for a[COLOR=#b22222] [B]TRIKE[/B][/COLOR] that does not steer by leaning a tire over.
On a [COLOR=#b22222][B]trike[/B],[/COLOR] some trail is good for straight line tracking stability, but excess trail will increase steering effort fast. You will not feel that increase with a[COLOR=#0000cd] [B]bike[/B] [/COLOR]so much, as they steer by leaning. The front is more like a caster wheel of a shopping cart with handle bars, and to steer, one leans the[COLOR=#0000cd] [B]bike[/B] [/COLOR]over by kicking the tire out at bottom with the first counter steer move[B] ….[/B] on a [COLOR=#b22222][B]trike[/B][/COLOR] you steer in the direction of turn and momentum ([COLOR=#b22222][I]inertia[/I][/COLOR]) fights you, which is why reducing trail reduces effort.
Below are some pics of a stock ([I]Black[/I]) OEM GL1500 tree set and Champion 6 degree EZSteer ([I]Aluminum color[/I]), you can see difference is in lower tree. Pics from Sep 2004.
