C.A.R.B Info

    This bike is awarded CARB Green Sticker certification, it's legal for sale in California and can be registered in California DMVs.
    In accordance to California DMV laws and regulations, dealers are required to complete and file registration for all vehicles sold in California. To avoid delays in the registration process, all California orders will be placed on hold until a “Vehicle/Vessel Transfer Reassignment Form REG 262” is signed and return to us. By providing us with the 262 form before your order ships, we will be able to provide you with a registration card and license plate in a timely manner. Please note that we will not ship out or process any orders until we receive a signed REG 262.
    After you place your order, you will receive an email or letter with specific instructions showing you how to fill out in the form correctly. You are only required to complete four (4) areas that will be highlighted for you. It is very important to leave all other areas blank. Place the signed 262 form in the provided envelope and mail it to us ASAP. Once we receive the signed original we will complete the registration for you. The license plate and registration card will be mailed to your address. There will be no further action required on your behalf after the completion of the REG 262 form.

    No any hidden charges or tricks here, we only offer you fast, reliable and honest services.

    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.

No Sales Tax

    We do not charge sales tax except in California. That's extra savings for our customers comparing to buying bikes from local vendors on top of our already lower sale prices.


    Look in your local yellow pages for lawn mower repair, small engine repair or go to and search for "motorcycles repair" or "ATV, motor scooters repair". Our bikes are similar to big name like Honda, Kawasaki, Suzuki bikes. Any bike shop with experience at those name brand bikes should be able to repair our bikes too. If you or your local technicians need any parts, simply give our parts department a call and we will send parts to you properly.

My son recently got this bike. We were a little reticient about buying a dirtbike on line. But decided to give it a shot. Boy, am I glad we did. My son is thrilled with his dirt bike. It is just as powerful as any brand name bike out there. And it's beautifully designed as well. We had a little issue but it was quickly resolved by Manny, the mechanic. He is absolutely wonderful . Although he is a very busy mechanic he took the time to explain how the bike works and helped us to resolve the issue to our complete satisfaction. I can't wait to do business with Bikenthings again!!! We are extremely happy with this purchase.

Bought this one for my son to ride, great fun and a lot of power, watch out in 1st gear you will pull a wheelie easy. Easy to setup, be sure you tighten up all the bolts around the sprocket and chain area. Great starter bike with no clutch to worry about, fun for everyone to ride, be safe wear a helmet and proper gear, fun for the family great shipping and support staff.
