    Key Features

      The 4-stroke engines have proven to be more reliable and durable than the 2-stroke engines. Chain Transmission and Pull Start provides much easier control and handling for young rides and gives the rider the great convenience in the event of a stall. Additionally with the 4-stroke you get:
      1. More torque: In general, 4 stroke engines always make extra torque than 2 stroke engine at low RPM.
      2. More fuel efficiency: 4 stroke engines have greater fuel efficiency than 2 stroke ones because fuel is consumed once every 4 strokes.
      3. EPA Approved: As power is generated once every 4 strokes & also as no oil or lubricant is added to the fuel; 4 stroke engine produces less pollution.
      4. More durability: We all know that more the engine runs, quicker it wears out. 2 stroke engines are designed for high RPM. If an engine can go for 10000 rpm’s before it wears out; a 4 stroke engine with 100 rpm will run for 100 minutes than the other 2 stroke engine which has a higher rpm of 500 & will run for only 20 minutes.
      5. No extra addition of oil: Only the moving parts need lubrication intermediately. No extra oil or lubricant is added to fuel

      If you are in the market for a smal dirt bike then the 4-stroke dirt bikes are your best choice. The small 4-stroke dirt-bikes are perfect for beginner use. However, it is also a fun bike for young rides who already know how to ride and it would be a great foundation for a pit-racer or backyard-track bike. It is a TON of bike and performance for the dollar.

      Normally it will take up to 3 business days to process your order. Most orders will be shipped from our warehouses in Los Angeles. After our shipping company picks up your order from our warehouses, the estimated delivery time will be 3-10 business days depends on your location.

      Shipping charge for one single unit of DB-Z005 is $99.95(Please login to see real shipping charge for these states: Florida, New York, District of Columbia, Connecticut, Maine, Maryland, Massachusetts, Montana, New Hampshire, New Jersey, Pennsylvania, Rhode Island, Vermont, West Virginia, Delaware, etc.) , and you will get discounted shipping price if you order multiple item.

      All ATVs, Go Karts, Mopeds, Dirt Bikes and UTVs will be put in a steel crate and shipped by a reputable trucking company to door directly. Electric scooters, pocket bikes, parts and accessories will be shipped by FedEx or USPS. We will email you a tracking number after your order is shipped. Our trucking company will always call you before the delivery and let you check the condition of your items when they arrive, so do not worry about that you could miss the delivery.

      Don't be fooled by some companies "Free Shipping" offers. They just add shipping charge in their product prices and their prices are usually $150-$500 more than our prices. In addition, some competitors only ship your bike to the nearest trucking company terminals, those terminals are not readily available in a lot areas, that means you may have to spend your own time, your own gas and get a truck and trailer to drive long way ( in some cases, it could be more than 150 miles) to get it. Also, some competitors will ask you to pay additional $30-50 for residential address delivery and $50-$75 for liftgate service. Those motorcycles are very heavy and in most cases, you do need those services and end up paying a lot more for shipping.

      No any hidden charges or tricks here, we only offer you fast, reliable and honest services. Our shipping charge already includes liftgate service and residential address delivery and we will deliver your bike right to your door.

      Note: For oversized bikes, there might be a chance that our trucking company driver cannot unload this bike with liftgate on his own. The reason is that there is no lift gate big enough to unload this bike and this bike is too heavy for one person to unload. If our trucking company informs us so, you are expected to have several friends to help our truck driver to unload the bike when it arrives at your door. You can also provide a business address with a forklift to us for delivery or you can go to trucking company local terminal to pick up your bike.

    Want a Rush Processing?

      Normally orders are processed and shipped out of our warehouses within 3 business days. If you pay for the RUSH option, we will ship out your order within one business day. If you have a birthday or need this order rushed to you, simply select the Rush Option when placing your order and we GUARANTEE to ship out within one business day. If for any reason we cannot get your order shipped out within one business day, we will refund your rush charge and still rush your order.

    Ride Safe and Have Fun!

      Off-road riding is great fun! When you take proper safety precautions, injury is less likely to occur. As a responsible rider, you must outfit yourself in appropriate safety gear every time you hit the trails. Doing so keeps injuries and equipment damage to a minimum.

      Buy a helmet safety approved by the Department of Transportation. It will have "D.O.T." stamped on the back, near the base. It should fit snugly, allowing very little head movement within the helmet.

      Purchase a quality set of goggles. Trail debris can hit a rider in the face, and sunglasses do not offer enough eye protection. Purchase special safety goggles that easily fit over prescription eyeglasses if necessary.

      Obtain a high-quality pair of off-road riding boots. Tennis shoes and hiking boots are not safe enough for off-road trail riding. A single rock can break an ankle on an ORV trail. Stout riding boots with heavy-duty casings are essential trail safety gear.

      Buy a comfortable pair of riding gloves. Vibration from the handlebars can cause sore hands and wrists. A good pair of riding gloves will absorb some of the impact and make your ride more enjoyable.

      Purchase the appropriate clothing. Regardless of outside temperature, wear a lightweight, long sleeved shirt and thick, full-length pants to protect the skin. Breathable material is necessary, as are bright colors easily visible to oncoming riders. Riding pants and jerseys offer the rider much needed protection from overhanging limbs, branches, and flying debris.

      Acquire a chest protector. Stones thrown by other ATVs and unexpected branches in the trail can hit a person squarely in the chest while trail riding. It is extremely dangerous to have the wind knocked out of you at 50 mph. A chest protector is mandatory safety gear for ORV trail riding.

      Purchase a good neck brace. It provide strong support and good protection to your neck and it is mandatory to wear for dirt riding in some states.

      We carry all types of high quality name brand riding and protective gear. Click Riding Gear to see our full selection.

    This was perfect. Came well packed no issues at all. Took about 10min to assemble because instructions are hard to see and vague. If you buy it is simple to put together. First put wheel on using longest bolt. Second attach rear shock using second longest bolt (lay bike on side to make this easy). Third take 4 screws from bag place rubber washer on then find holes on side of seat and tank and attach to frame. Fourth attach fender to front. you will need to remove lower bracket bolt and put fender sticker side front. Fifth attach handle bars by removing brackets and resetting. finally add number plate to front using bolts in bracket. Check oil level and yes it comes with oil. Gas up and givebthree pulls in choke(all the way down on white lever) move lever to middle and pull until start. let run a second then lever all the way up. if it fails to start repeat again then continue to pull in top position. make take a few pulls to prime it. So yes if you want a quick little bike at a good price that will arrive on time in a few days this is it.

    Quality little dirt bike
    I was hesitant about buying one. I had a friend to buy two for his children and bragged on them for a couple of months, so I reluctantly bought one for my grandson. He has put a lot of miles on it and we have had no regrets. The only problem that we have had is he occasionally hits the choke with his leg and chokes it down and I have to go out to crank it for him which is very easy for me. It has been a great little dirt bike.
