For 1986-2003 Harley-Davidson Sportster engines
Includes MSO (Manufacturer's Statement of Origin)
32 degree rake neck in stock location
Uses stock rear axle and rear wheel
Highest quality available with perfect fit and finish
Made in Cleveland, Ohio, USA.

The Gasbox full frames are the highest quality and best engineered available. This frame allows direct bolt-in fitment for 1986-2003 Harley Evolution Sportster engines. All 1 inch tubing, completely TIG welded and made in Cleveland, Ohio, USA.

Unlike other custom frames, the Gasbox full rigid frame uses stock motor mounts all around, with the engine cradled low in the frame rails just like a stock bike. This looks much cleaner and keeps the finished chopper looking lean and handling better with a lower center of gravity. The frame will require use of early style front motor plates (Gasbox Motor Mount Plates SKU 005585 or Harley OEM 16210-52 or A-22041), and also requires an early style kickstand.

The neck has a 32 degree rake and is in the stock location, this frame has no 'up' or 'out' dimension to the neck, is set up for a 1" stem, and utilizes 1" stem Timken style neck cups. This stem size is very common and is found on narrow glide front ends on Sportsters 1982 and later, and on Harley Big Twin front ends, including narrow glide, wide glide, OEM and most aftermarket springer front ends.

The rigid rear hardtail section has approximately 4 inches of stretch and is set up to have 2 inches of drop. This means that with a front end and wheels on the bike the lower frame rails sit 2 inches closer to the ground than stock for that perfect stance. The axle plates are set up for a standard 3/4 inch rear axle and accepts a stock disc brake Sportster rear axle. This frame also features integrated upper mounts for Horseshoe Oil Tank SKU 010404. The Gasbox Battery Box Adapter Plate allows easy mounting of all Gasbox universal battery boxes to all Gasbox Full Frames and also features an integrated lower fender support. The gas tank mounts on this frame are designed for direct bolt on of the Ironhead Sportster Replica Stock Style Gas Tank SKU 007587.

This frame is designed to use Lowbrow Customs Rear Chain Adjusters for 3/4 inch Axles. This frame is designed for use with disc brake rear wheels, and requires the use of a custom rear brake caliper and caliper bracket. Stock Sportster disc brake rear wheel and axle are a perfect fit. Aftermarket wheels can also work though you will have to pay attention to proper spacing to ensure your chain lines up. Some options are Cycle Standard 16 x 3.00 inch rear wheels, such as the Black SKU 010383 or Chrome SKU 010382.

Once you receive the frame you will follow the included instructions and contact the Gasbox and the MSO (Manufacturer's Statement of Origin) will be mailed directly to you. This will have the frame's individual serial number (stamped into the the neck of the frame) as well as the purchaser's information. This is needed in most places when titling a custom motorcycle.

Note: There are no returns on carburetors, electrical items, full frames, hardtails or made-to-order items (such as magnetos) unless there is a manufacturer’s defect.

The quality is excellent. However I was a bit bummed with the compatibility of stock Harley sportster parts. The gas tank mount holes didn’t line up with my stock tank. The forward control brackets and the rear caliper is not compatible with my stock parts. I was planning on reusing all these parts and now I have to buy all of them. But I guess that’s what comes with building a custom bike

Great Full frame hardtail to build off.

Me and my dad wanted to do a bike build for the fall and winter time. I was looking to go with the back half kit and just chop my sportster frame. My dad saw this and liked how the neck area was smaller and liked the over all look of the frame over just back halfing a sportster frame. If you follow along with the PDF listed on this page you'll do fine but there was a few problems we ran into with some items they listed. One thing I would change if I had to do it again. I would just go with a cobra seat and not a solo spring seat, nothing is wrong with the spring seat and it looks great I just wouldnt go with what they recommend in the PDF. It's a little small width wise for a bigger guy. Check out some of picture, frame looks great painted and hopefully will be able to get it done before spring time.

Working on an Evo Sportster build with this frame. Do you know of a king/queen seat that will work, similar to Sully's Customs SKU: 008346?

I recently purchased the 86’- 03’ ridgid frame, what bearing do the necks use? I tried a oem bearing and it was to large.
