I see a lot of front end builds where the bottom a-arm is longer than the top a-arm. It's interesting that this example is exactly the opposite. It was my understanding that a shorter top a-arm better aligned with the ground during turns or going over bumps. Is this not the case? I'm interested in building a reverse trike that's why I'm watching as much as I can about these alignments. Any advice would be appreciated. Thanks. Great video by the way. Very informative.

Love your bike kits....although out of my budget right now. I have a 2020 Ryker 900 and i heard you say Kenda tires are crap. What tires do you recommend?
Can you tell me your reasoning on using Caster Angle on the Uprights, and opposed to having 0° Caster, and a rearward-offset Spindle (Axle)? There are two reasons Bikes use Rake Angle; 1. Telescopic Forks 2. Aesthetics OK, maybe a third reason, an easier/cheaper/lighter build. I see no reason to have a Rake/Caster Angle on a car-type Suspension set-up.
Good question. All vehicles in general run some caster. Normally 2 to 4 degrees. This caster adds trail which improves straight-line stability. Zero caster will cause the trike to wander. Too much caster will cause undue cornering effort. But in general some positive caster is mandatory
Great video. Question about the alignment. When you measure your toe in/out for the Ryker do you measure from the center of the ride to determine correct specs?
I am guessing you mean measure from the center of the tire? It doesn't matter where you measure as long as you use the same locations on the front and back. You can go outside to outside, inside to inside, center center or mix them up as long as it's the same when you measure front compared to back. in general 1/8 to 1/4 positive is a good start then just watch tire wear and adjust as needed. If it's off a bit the tires will show it after a few thousand miles. it really is not a science so some guesswork is involved.
You should take a ryker and make little kits for it and sell them make a bigger front end for storage or bigger fenders for bigger tires or more aerodynamic
Shouldn't the upper arm be a little shorter than the lower, to keep the wheel vertical and maximize contact patch as the outboard spring compresses during cornering? It looks as though the upper arm is longer, which is contrary to any automotive practice I am familiar with.
Not necessarily, to tune the handling and provide understeer requires a different approach. CanAm and most others including endeavor all do the arm in this fashion on purpose
Hay all u young bucks. Respect this generation!! This is how its done without all those fancy expensive tools!! With age comes invaluable experience!!
Thanks Mate!. I've just bought a 2017 F3 Daytona, and you have answered a few of my questions. I appreciate your talk.

I have been using Federal and Achilles as they have good water displacement and last well. I get all my tires from Tires-Easy.com
What size tires and rims are you using
