Affordable Ultima® Build-A-Bike® Kits
Display Bikes - Unassembled Motorcycle in a Box
Please review Bike Kit FAQ before sending questions. We do not ship internationally.
If you are pricing kits somewhere else, ask them how they handle back-ordered parts; most places DON'T. We will get you all your parts, even if they are on backorder at Ultima (we have many other sources). No matter where you decide to buy from, check the forums, such as Club Chopper, first. Don't get ripped off!
Note: not all parts will ship at one time. It may take time to find parts elsewhere. Since you will be doing a mock-up before final build (right?), this should not delay your project. We believe in being honest up front in all our business practices. We don't just want to sell parts, we want to create a long-term customer relationship.
