Slipstream performance has prices for everything if you go there Mr. Phil. The HRC stuff is expensive because it's straight from Japan but you will see some decent gains from it for sure depending on what you do to the bike.

 

The power up kit runs about 6750 bucks so be prepared to have your eyes bulge out of your head.

 

Small gains and because if you have to ask you can't afford it.....

 

That is very true. The HRC prices are insane. They do offer a couple parts that you can't really get anywhere else unless you have them custom made. Those would be the only parts I would ever buy from the HRC line. The HRC quick throttle kit I put on my bike wasn't too bad on price though. I paid 135 shipped to my doorstep for it. It included both throttle cables, new kill switch/starter switch, throttle housing and throttle tube with detailed instructions on how to install it. I got the 1/6 kit not the 1/5. The 1/6 is a little more street worthy I think.
