The Box

The Kit - lots of parts, great instructions, should be fun to install.

Rough dyno comparison. Ignore what is says, it is a stock 06 trx450r vs the same with the HRC kit

 

Go to your my page tab inbetween gallery and profile or if you have a link, hit the http tab in the reply to thread area.

 

Just bought a new '06 450R/ER two days ago. What's the HP on a stock 450R? How many HPs will it have after the HRC kit is intalled. I'm on the waiting list from my dealer when they arrive in the next week or two.

Thanks!

 

I'm hearing figures like 50 hp with the kit installed.

 

Any idea how much the kit is?

Also interested in how much other shops charge to install it.

All I know if the new 2006 TRX450R STOCK is totally awesome.

This kit is scheduled to be installed tomorrow, so by tomorrow night we should be able to provide a installation/riding impression.

I think we have another one or two ON HAND - I'll check tomorrow.

Also, let me suggest that you DO RUN the Honda MOLY oil in the engine, and the normal NON-MOLY in the tranny. Two seperate oiling systems. Some shops just dump the non-moly in both, me, with the unicam head, I prefer the moly in the motor.

Ask your shop if they do that, I am interested in what other's do as well, always something better!

 

My dealer quoted me $299 for the kit and $150 for the installation.

 

The kit contains a really nice new head pipe, a couple options for the rear baffle (one is AMA only), opens up the air box, new radical cam (+2.5mm intake lift and +1.95mm lift intake, revised timing), a sub harness to raise the RPM limited 1000RPM and changes the ignition curve and all the related carb tricks and settings.

FYI

 

I know the labor is exactly the same as we charge.

And $299.00 seems like a bargain.

I thought cams cost more that that alone!

GOOD LUCK and appreciate your comments VERY MUCH.

 

Could you please post the exact cam specs for the 2006 kit that are printed in the HRC manual? I would like to compare the 2006 specs to our 2005 kit cam spec.

We ran the 2005 HRC cam for a short time them removed it. The dyno showed a nice shift in torque and horsepower to the top end, ok for motocross but it took away too much for GNCC racing.

Thanks.
