does anyone have any experience with the motor out of a honda crf450r dirtbike. lonestar makes a 400ex chassis that has motor mounts for a 450r motor and i was wondering how the 450r compares to a yz426. also does anyone know where you could get a 450r engine and how much they are. thanks

 

hey guy i have a 426 and its like riding on the devils back.but my buddie bought the honda and him and my son both say it is almost as powerfull as the 426 but more controlable power the 426 is a mad dog.try calling bobs used cycl parts in phx ariz he buy's a lot of wrecks from ins co's maybe he can help you.

 

hey how much HP are you getting out of your FULL BORE 440EX?

 

I HAVEN'T PUT IT ON THE DYNO YET BUT OVER MEMORIAL WEEKEND MY DAUGHTER 13 YEAR OLD DAUGHTER BEAT ALL RAPPYS [STOCK] AND Z400S AND CANNON DALES WITH NO PROBLEM
@SAND MOUNTAIN NV WE JUST FINISHED IT AND STILL HAVE SOME MODES TO DO WISH I KNEW HOW TO POST PICS CAUSE IT LOOKS LIKE NO OTHER.

 

Beat Cannondales with no problem, ah yea, sure!!??[img]i/expressions/face-icon-small-wink.gif[/img]

 

Hey Loudpipes! I have a Lonestar/CRF450r quad, everything Lonestar builds is on it. You can buy the motor from your Honda dealer for around 3500-4000 depending on how well you know your dealer. Then you still need carb, cdi,modified kick-start, exhaust and many other little mods you thought you knew about.{much more $$} The CRF450r is a holeshot mother in motocross and will start easily when hot. The Yam. 426 I had was a pain to start when hot.

 

I couldn't agree with you more rodsquad the 426 is a tempermental pig to start.

 

Thats a bunch of BS above....I got a 2002 CRF450 and I will smoke a 426 ANYDAY....I do all the time. Dude...don't listen to him...read the shootouts! [img]i/expressions/face-icon-small-smile.gif[/img] The Honda is lighter...has MORE power...starts EASIER (has a decompression-like lever for easier starting). Sell that kids toy 426!

Bottomline

 

careful CRF 450 guys Yamaha just release YZ450 this year and it has alot more power than the old 426! I really hope that Yamaha will come out with that 450 engine into quad and also with that YZ250 fourstroke engine into quad too! That 250 makes 41 hp at crank and 13,000rpm redline!!

See ya,
Dusty
