This past weekend I did a wheelie
A little too much for me
So me and a couple buddies made some front end limiters to prevent the front end extending too much
Hopefully this tames the wheelies down
I am jealous of your wheelie. makes for a great photo, but hard on parts and expensive.
I have always not-comprehended how a front end limiter works. I know it limits how far the front suspension can hang, but how does that limit how far the wheelie goes up?

You know how a truck climbing a hill gets easier and easier to flip over backwards as the hills gets steeper and steeper? Same concept.
The higher the nose, the further back is the center of gravity, and the less torque it takes to rotate the vehicle around the rear tires. His long travel springs were helping to throw the nose up to a high angle (CG further back) before all the weight was on the rear tires. Takes less torque to continue to rotate the vehicle to pick the wheels off the ground.
Shorter spring travel makes the front tires unweight earlier in rotation when the vehicle CG is further forward. Takes more torque to continue to rotate the vehicle up in the air. Basically he's using the weight of the vehicle to keep the nose down.
ah-ha! ok, I can visualize it much better now, thanks guys. longer springs helped launch the vehicle up higher, and shorter (shortened via limiters) take away the full "spring" of the spring.
