well i built my first jump today... it was alot of fun actully it took me about 45 minutes to do... that includes gathering all of the scrap wood i could fine lol...its about 4 1/2 - 5 ft tall and id say near 40% slope its pretty steep... and its not long enough... i wil get all the measurements for it 2morrow but we didnt plan anything we juss started slapping wood down... we are going to make another one... and we are gonna make this one a lil wider our current one is only 4 ft wide the z400 has 2 inches of room lol... and long cuz its to steep and you get the indo affect no matter what you do... so we jump down hill lol... i wanted ot know like what are some good things for jumps though? we put 3 supports on the end and 3 supports in the middle and 2 in the very front... holds up really well it hink...ive also seen alot of those like kinda curved ones... how do you do that? i am reall yinterested int this and would like to build me some kick a$$ jumps for this winter

 

let me know if you want any help?

 

The way to get the curve is to make the sides first. you take your plywood or osb and trace the curve you want. then you cut it out. then nail/screw 2x4, or 2x6's to connect the two sides together (I did this for bmx/skate boards, so you will have to make sure you use strong enough materials to hold up to the weight of the 4 wheeler). Slap another piece of plywood on the top and strap on your helmet.

 

Right now we are making a 6 ft high 15 ft long straight incline jump... we are gonna try the curves after we see how we like this one.. its pretty monsterous lol... but we are building it like you would a ruff... triangle inside triangle yea know trusses... how you all think that would hold up? o another question is this is going to be like a monster heavy jump... how do you all move yours around?

 

bigblock2stroke.... im not following what your saying?

 

mines a two piece jump, it get the curve if you want your jump 15' long and 6' high run a piece of string from the two pieces and let the middle sag untill it looks like a smooth transition.

 

sup, im one of the two people blaster2fast is building the jump w/i pretty sure i understand what you meant bigblock2stroke so i will try to explain it to blaster2fast later. yeah our plans for the big jump is just to have 4 half truss, right triangles 2 feet apart and then just lay some plywood across the tops of them so it just a straight shot. i figured this would be the strongest way to build it cause roofs are built like this and they hold a ton of snow up here. But a curve one seems like it would be kewl we'll try this out first. We were also thinking of a wheel system for it. Some kind of wheels that we could just fold down on each corner and put a pin in to lock it. We don't know where to get the wheels, we were thinking about shopping cart wheels but we don't know if they would be big enough, but they are already set up to rotate and all. Let us know if that may work or if you got anyother ideas.

 

I don't know where you guys are doing this at, but I highly recommend dirt.

 

Glad you figured it out.

The triangle jump will be more of a "float", where you don't really spring off the end of it, you just ride over it. The curve jumps spring you more up the out because the suspension compresses a little as you drive through the transition. Easy way to put it is usually the triangle jumps are good for distance and the curved jumps are good for height. In either case, you had better make a landing ramp or jump down hill. Flat landings suck and you will be rebuilding your shocks (or yourself).

Good luck, start off easy, work your way up to it, and don't ride past your means.

 

we know landing flat is bad so we were wondering if just jumping down a slope would work? rather than wasting time with building a down hill?
