Does anyone have a dyno that shows the difference between a STOCK 450R and HRC kit with no other ad ons? I'm curious to see what the powerband looks like.

 

Ryan- Dirtwheels did a dyno in the march 2004 issue between the yamaha, honda and gas gas.

stock 450r honda- 37hp at 7300 rpm
stock 450 YFZ yamaha- 39.3 at 8050
yamaha with gyrt slip on, air box mods- 44.6 at 8200
honda 450r with white bros pipe, air box mods 40.0 hp at 7200
gas gas 450 42.3 at 9300 from the factory.

 

Thanks for the reply. I saw that article, but they didn't actually do a dyno run with the HRC kit...

 

I would think as popular as the HRC kit has been it will show up soon in a mag dyno. I would think it would add another 2 or 3 hp and another 1000 useable rpms. Changing the carb for a FCR should add another hp or 2.

I would bypass the hrc kit and find some aftermarket cam from a dirtbike shop. You will have to probably wait a little bit on a piston. I do not know if anyone has done a run yet. Hopefully sparks, lrd, ESR will have a few before to long.

 

14mins have you had a change in heart?? well whatever it is i like it cause you used to be like my least favorite forum member and the last couple of post you have put up are really good post. very good information. keep it up. we need to get as may bashers outta here as possible[img]i/expressions/face-icon-small-smile.gif[/img]

 

niceman- no change of heart. This post has no BS going in it yet. This is how i believe you are going to get the power out.

Anyone know the price of a HRC kit

 

ebay has one for $250

 

Honda is selling them for $300. The dealership that I'm working with says they'll give me a 10% discount for the first year after a purchase...But I'm sure their prices compensate for it.

As for the aftermarket cam, I probably will wait and see what becomes available. I kinda like the HRC kit though, because it just modifies the airbox, rather than removing the lid altogether. It puts a vent in the lid that still directs any debris/water away from the filter. Also, it opens up the exhaust a bit, without costing me a small fortune to upgrade the whole exhaust. Wheter that's worth half the price of the kit...probably not. [img]i/expressions/face-icon-small-smile.gif[/img] Eventually, I'm sure I'll end up getting a full exhaust for it, but right now, this is what I can afford.

I don't think I'm going to worry about a piston. I'm not concerned with being the fastest and baddest 450R out there, I just want more usable power. From what I've heard, between dropping a tooth in the front, and the HRC kit, the R is much more ridable in a variety of conditions.

 

HRC kit is a waste just for a cam. Just buy exaust, remove lid, and wait for cam and piston. Hopefully then my Honda 450r will keep up with my YFZ450.

 

Rodsquad- I can not picture you kick starting anything in the year 2004. LOL I am thinking of a day trip to your house to just see the 450r in person. You going to wear the pink riding pants when on the 450r???
