about this hrc kit i myself saw a stock 450r get dynoed at little sahara an editor of this forum us doing it it had 36 hp stock and 38 with the hrc kit 2 hp for 600+ i would not tell you a lie i saw it 1st hand ask (rex) on this forum he was there

 

Whoever paid over $600 for an hrc kit needs a kick in the nutz lol.

 

or however much it is

 

I have seen before and after dynos of the HRC kit, and all the difference is in the mid to top end. No real changes on the low end. Low end is strong on the Honda anyway (at least compared to the Yamaha), but Honda tames it down with tall gearing, no doubt specified by their lawyers who don't want to see somebody wheelie the thing right out from underneath themselves! If you really want a HIT, ride a Banshee!

 

I have the 13t for when I trail ride. It doesn't make it wheelie any more than the 14t. Makes it much better for tight and techincal trails. Going to the dunes I switch back to the 14t. This month I'm going to try a 14/37 combo at Florence.

I have a stage II hotcam, rejeted and open air box and 2" end cap. Pretty much the same setup as the HRC kit. I feel the cam mod made a real difference in the top end hit. I love it.
