Product Description
Your swingarm is the main component of your motorcycle. The swingarm helps manage the load distribution and center of gravity. By extending your swingarm you are making your motorcycle forward heavy, giving it a low center of gravity. By pushing the center of gravity as forward as possible, you are reducing the chance of your motorcycle wanting to wheelie on hard acceleration, allowing you to launch harder off the starting line.

One of the most asked questions we get is, what length swingarm should I choose? We have put together our general recommendations on wheelbase lengths based on different use applications. If you have more questions, send us an e-mail for help.
STREET USE
- Street Use Only – 8” over stock with 4” of adjustment
- Street Use and Drag Racing (Street ET or Pro ET) – 8” over stock with 4” of adjustment
*Note: Any stock motorcycles with a swingarm over eight additional inches more than likely will need an aftermarket tail.
GRUDGE RACING
- All Motor – 77-82” wheelbase
- Nitrous – 75-82” wheelbase
- Turbo GSXR-1000 – 77-82” wheelbase
- Turbo Hayabusa – 75-80” wheelbase
SPORTSMAN RACING
- 8.20 or Faster – 70-75” wheelbase
- 8.20 and slower – 64-70” wheelbase
- 9.00 and slower – 4-6” over stock
SWINGARM LENGTH
When measuring wheelbase, measure to the longest length needed, our 4” and 5.5” adjustment options are forward of the wheelbase length chosen.
Example:
- 80” Swingarm with a standard 4” adjustment – your swingarm will be adjustable by 76”-80”
- 80” Swingarm with a standard 5.5” adjustment – your swingarm will be adjustable by 74.5”-80”
FRONT MEASUREMENTS
We build arms based on stock measurements, so if your bike is NOT currently stock, we need your front measurement as well. To take a Front Measurement, measure from the center of your front axle to the center of your swingarm pivot. Measure away from the motorcycle to keep your tape measure straight for accuracy.
If you change your swingarm do you have to change your shock, can street riders keep their stock shock?
Answer: DME Racing swingarms are a direct replacement and you can run the stock shock.
At what length do I need to add under bracing to my swingarm?
Answer: We DO NOT recommend underbracing. DME Racing swingarms are designed with a special extrusion that gives them ample strength even at 80+ inches. Some of our customers feel safer with the extra underbracing, and we are happy to add it.
What is the Torque Spec for the rear axle nuts?
Answer: Recommended Torque on the swingarm bolt is 60 ft. lbs.
What is the Torque Spec for the front pivot axle?
Answer: We do not have a recommended torque spec on the pivot axle, however we do recommend that you tighten it until it is tight but has no side-to-side play, but will still move up and down smoothly.
What socket size is needed to remove the axle on my DME Racing swingarm?
Answer: 1 7/16"
Why do you suggest an aftermarket tail on a swingarm of more than 8" over stock?
Answer: Once you extend your swingarm, you are pushing your back tire position farther back, and for most bike models, that will cause the back of the tail to hit your tire when you are sitting on the bike or launching hard.
