Can someone please tell me why one of the first things done to a brand new bike is add slip ons?
Why can't these things be included when you order the bike?

Thanks

 

Three little letters. EPA. If they sound and perform good they are not good for the enviroment. So they say. Besides not everybody wants sound and performance. There are plenty of people content with a bone stock bike.

 

1. EPA restrictions on emissions (noise and exhaust)
2. Too many different types of performance exhaust systems.Every system they through on as stock would have to be certified by the EPA which ain't cheap.
3. They put 2-1 on, and people will bitch that they should gone with true-duals, or that they should have kept the stock crossover design, or they should be black ceramic coated, etc etc.
4. Why include something people are lining up to pay for?

Does EPA restrictions on emissions apply to used bikes?

 

In some cases slip on's can be added when you order your bike, they just added to the bill. One way or the other, your going to pay for them.The reasons people add slip on's vary from looks, to sound and/orthe bike runs better with other then stock mufflers. Lot of slip on options and those options can be fewer or greaterfor the buyer and the dealer depending on where the person lives. Enjoy!

 

The short, legal answer is yes, 1979 and later vehicles.
The practical answer is only if somebody is doing smog or noise checks where you ride.
The above posters are right, Harley builds a bike that is made to be modified (customized). There are quite a few things on a stock bike that can be exchanged, not just mufflers. There is also more than one option for what you want to put on. That, and money in the form of future parts sales, are why the moco build a basic product.
