hmmmm, for a bigger bike i'm not sure whether to say steeper or mellower. i built a 5' tall ramp and used an 8'6 radius and he rides a jackal and says its perfect. if your going to be backflipping maybe use an 8' radius
ok, cheers. yeh usually the ramps/jumps I build are mellow, as the wheelbase of my bike is quite long.
How would I go about constructing the jump with that radius, say? I've only built smaller ramps before, and only by eye, as the radius wasn't that critical.
Looking to build a Volcano , 4ft high, just dont know exactly how to go about building it, any one have a idea on how to please? need help asap!!! cheers
just drew these up on Google's Sketch-Up. Should help anyone looking to build a kicker. The surface plywood is covering half of the ramp, to give you a look at what it looks like finished but also show the ribs.
Contact me with any questions, or simply post in this thread. Enjoy!
