Frequently Asked Questions :

Do you finance?

Sorry, but no, we do not finance.

Will you ship outside of the U.S.?

At this time, we ship to Australia, and to other countries when feasible. Please contact us for an invoice.

What if I can't find what I'm looking for?

We carry parts from most major suppliers, and several smaller companies. If you don't see it, give us a call (417-468-2326). If you have any of these catalogs, you can order anything in them: Mid-USA, Biker's Choice, S&S, Midwest, Kustomwerks, Xtreme Machine, Arlen Ness, Tucker Rocky, Deep Cut Rotors, Drag Specialties, Dealer Leather, Mustang. Many of these also have online catalogs. Make a list of the part #'s and give us a call on our toll free order line: 1-866-889-7828. The more you buy, the more you save!

What about shipping?

Most parts have flat rate shipping within the continental U.S. If there are any special trucking charges or refundable crate charges (engines) they will be explained on the webpage.

The chassis kits are sent by UPS or truck depending on supplier. Engines usually ship by truck, while frames are usually shipped via UPS. Some small items will be sent via USPS Priority Mail.

For Australian and other orders, we charge whatever the shipping charge is (no handling fees, etc.), or you can arrange your own shipping.

Our shipping and returns policies can be found here.

Do I need to be a membe of PayPal to pay online?

No, you can just use your credit card via paypal.  Look for the link on your check-out page.

Can I apply for a dealership? Do you sell Wholesale?

No. Although we try to sell below retail whenever possible, we are a "retail" dealer, not wholesale.

Do you have such and such part for my Yamaha, Suzuki, Honda, Kawasaki or other foreign make bike?

No, sorry.

Can you match or beat the price of a competitor?

No. Our prices are as posted. If we matched the prices of the "cheap guys", we'd also have to match their customer support... which is not much. (We get phone calls and email every day from people who can not get help with an item they bought from a "cheap" source, or who have waited for back ordered parts so long they have given up. You get what you pay for.) We'd rather continue to help and support our customers, which takes time and effort.

What is meant by "rake" and "stretch" when looking at frames?

Confused about frame terminology? See tech tip #9. See tech tip #10 for a rake and trail calculator. TECH TIP PAGE

I didn't get instructions with my part. Can you send me the instructions?

Most aftermarket parts DO NOT come with instructions. Please refer to your HD manual. 

Do your frames, engines, and transmissions come with MSO's?

All of our Frames, Engines, and Transmissions come with serial numbers and a Manufacturer's Statement of Origin (MSO). The MSO's are usually sent about 30 days after the item has shipped. You will receive the original copy, notarized, usually by priority mail, signature required (for your protection). Please do not lose these. There is a fee to replace a lost MSO.

What about the EPA regulations on bike building?
The EPA has recently admitted that it has no jurisdiction over individuals.  They can only regulate businesses.  As usual, you should always check with your local motor vehicle regulations before starting a build, but the EPA regulations will not effect you.  THEY CANNOT STOP YOU FROM SELLING YOUR BIKE, or regulate how many you build.
