How To Build Dirt Jumps

There are many different tips to take into account when building a motocross jump for you to practice racing dirt bikes off of. These jumps are common in motocross dirt bike race tracks, allowing riders to launch themselves up into the air and do tricks, adding a bit of flare to the already exciting racing sport. One good way not to push the wheelbarrow all the time is to put one and half times what you desire to have as the height of the jump (for example, a beginner that wants a jump 3 feet high actually needs 4.5 feet of dirt because of the loss from compaction) so you won’t waste time shoveling again and pushing that wheelbarrow every time you need a little dirt.

Even small rocks, which may seem to blend into the dirt when you first build them, will get partially exposed after a few rains, which will be cemented into the jump like a giant cheesegrater, ready to rip your flesh away like so much Cheddar should you fall on it. Once you have some really big wide piles of dirt where you want them, start packing them down by walking on them.

During the period of the mid-90’s Cairns suddenly blew into international fame with the successful bid and hosting of the 1994 and 1995 World-Cup mountainbike trials, it was at this same time when the local crew began hunting the park for an area where they could build and ride something to replace the sparse jumping zones scattered around Cairns, which usually were made up of building sites.

Jumps that are too small don’t allow a rider much time to pull up and control the bike. Then, sort out any other problems such as cracked lips, ruts, puddles, general crap all over jumps such as leaves and stuff, by using your common sense. Great dirt jumps can be build on a flat spot, but you make it much easier for yourself if you find a downhill spot. Radical Bikes are host to an annual Trials, Dirt and BMX Festival called ‘Radfest’.

We’ve heard the stories of people who have poured the time, money and energy into building a motocross track, only to have ridden it a few weekends before the locals / neighbors kicked up a stink and had the council shut it down. I was chatting earlier to Ian Warby, who is CTC’s expert on off-road cycling (mountain biking, BMX, dirt jumping – that kind of thing). As we all know, TR has an area that is perfect for a skills section with some small roller jumps. So…we came armed with an extremely long water hose, about 20 workers and a bobcat ready to build some jumps.

Dirt Jumping is similar to BMX or Mountain bike racing in that the rider jumps off of mounds of dirt It differs in that the jumps are usually much larger and designed to lift the rider higher into the air. I work with him here and there when he needs me. Lately I have been traveling around turning wrenches for Powers Bike Shop at the bmx races. The evolution of mountain biking goes beyond the development of ultra-technical trails – it also includes a resurgence in dirt jumping and bike parks. Even though the jump will only be 2 feet high, you’ll be packing down the dirt, so you’ll need a LOT more dirt than 2 feet worth.

For extra dirt, dig dips in between landings and take offs, this will make your trails nice and smooth and will help with more dirt. Once you figure out what kind of jump you want and how big it’s going to be then you have to decide what to do about dirt. Building your own jumps is the safe and sane way to improve your jumping skills in the privacy of your own backyard. BASS: I was pretty much born on two wheels, started racing BMX bikes when I was seven years old, and then branched off to dirt jumping when I was 16. Build a basic oval track, then later build a track in the lower space further down the hill.

The tricks have evolved a lot partly due to freestyle motocross evolving where a lot of the dirt jumpers get their inspiration from. If you’re making a jump on a hill or if the ground is slanted (having the jump go uphill is easiest) simply dig dirt out below the jump and pile it up on the base of the jump. With the new generation, guided by the few remaining members of the original and older generations of riders, the centre point for activity in the Smithfield MTB Park was moved to the ’04 Nationals site.
