R6 Parts

Hey I was wondering if all the hardware and 06 Yamaha R6 can be lowered onto the pieces of stock? ... Otherwise what do I buy to lower it? ... I want to lower about 2 inches or so

In my opinion, Do not lower the bike.It leads to unpredictable handling in corners, the bumps may be more difficult to handle and can vary over speeds.Ground clearance problems may occur.
If you want to go ahead with it, Tees should be fine, as suggested by the initial response.

You can reduce the front end at least two inches by sliding the forks through the yokes.
The back needs "links reduction" to lower, look on ebay for them.

Warning: Low bike can greatly affect the handling, and is not recommended because it reduces the ground clearance while turning.

Yes you can. You want to be sure its done correctly so that you only affect the handling. It is a right way to do it and bad ways. This link will show you what you need to lower the rear. http://www.alibaba.com/product-free/2591 ...
