I modified my bike mainlyto enhance myability to touch the ground. lol Being only 5 ft tall makes it difficult to touch on a stock 2001 F4i. So I lowered both the front and the back. I bought it with the back lowered but then the bike cornered really poorly. I decided that to even it out and make the ride smoother it would be best to lower the front too. The bike corners very well now, no problems yet *knock on wood* ...

Other than that, I put on a Yoshimura pipe because I liked the way it made the bike look. I would not suggest this pipe for loudness because it is not much louder than stock. If you wanted a loud pipe, go for the Two Bros shortie pipe.

I also installed frame sliders to protect the frame incase I wreck. I got the ones that you have to cut a hole in the plastics for, but my boyfriend (jaynd) helped me with the technical part and it was relatively simple. He recommended the ones that you cut the plastics for the durability since they connect straight to the boltsof the frame. I especially am pleased with this investment as others have said because of the functionallity. I dropped my bike while I was learning [:@]and the frame sliders litterally saved me any damage.

I am also in the process of putting rim stripes and wing shadows on the bike. These mods are also of course just for looks.

In my opinion mods are for fun and functionallity. The ones that I did were for safety and glamour. lol If you enjoy the bike as is and it's safe for you to ride then I don't see a problem with you keeping it the way it is. Make your bike your own.
