Ezi Steer rake and trail
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 fromthe original top yoke to calculate the trail or the lower one
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.Originally Posted by nucseal
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.
Hope it helps. 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.
Not sure that's exact on a stock GL1500, maybe … but I would say close anyway. The standard set up for a BIKE is not necessarily great for a TRIKE that does not steer by leaning a tire over.The standard setup for a bike is 30 degree rake with a 111mm trail
On a trike, 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 bike 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 bike over by kicking the tire out at bottom with the first counter steer move …. on a trike you steer in the direction of turn and momentum (inertia) fights you, which is why reducing trail reduces effort.
Below are some pics of a stock (Black) OEM GL1500 tree set and Champion 6 degree EZSteer (Aluminum color), you can see difference is in lower tree. Pics from Sep 2004.
Hi Thanks for your time in posting this information. I know all about rake and trail setup. but the photo are spot on they show me the difference in the trees. so I can work from that. thanks againHope it helps.
