I thought mew was new too by his question. No offence but if I were new to say a Yamaha R1 Forum, after a year of riding my CBR600RR and learning about in that year, I would know that basically all the 600's and Liters out there have the same mods offered from aftermarket companies. Some have more then others like Ducati and depending on what bike you have you might not want to mess some mods like the front signals a newer GSXR 1000 because they are integrated in the mirrors.

I agree that track days and riding schools are number one but I personally like to spend money on accessorizing all my hobbies from my Glock 23 to my CBR.

 

I don't know if anyone else caught this...a lot of people's first mod is a fender eliminator kit...he went straight to the suspension to setup for him....nice call...SHOWS experience.

 

yeah i didn't catch that. and i suggested suspension adjustments. oh well, mark that off my list of suggested modifications.

 

Undertail comes to mind-do the exhaust while you're at it. I run the Yoshi RS-5 but there are others out there that are nice also. If you're a pretty quick track day rider or racer you'll also need rearsets, the stock pegs do deck out a bit early. I have the Vortex and absolutly swear by 'em. The flapper mod is free and easy. EPA noise restricions forced Honda to place a flapper door at the airbox entrance. If you've noticed, when you pull from a stop, it's not the smoothest action under 6k rpm or so. Look inside your left fairing opening just in front of the engine. You'll see a gold solenoid w/a vacuum line attached. Pull the vacuum line off and plug it. Now the door will be open all the time and the bike won't initially starve for air. When you start it engine vacuum shuts the flapper and it won't open till after 6k or so. This has been dyno proven many times over and you'll definately feel a seat of the pants difference when leaving a stop and at low rpms. Best of luck, enjoy the bike!
