Supercross Long CRF450R header pipes?

Recommended Posts

Is it my imagination or are the header pipes getting 1" longer every SX meeting on the Team Honda and Geico CRF450R engines?

Check out the latest TWMX pics here: http://motocross.transworld.net/1000092355/features/race-report-toronto-sx/2/?nggpage=2&pid=63760#ngtop

The pro Hondas have headers which are getting ... very ugly.

By any definition RD#5 and RV#2 have very short compact headers, and I find it hard to imagine the yellow or green bikes are down on bottom end torque. :banana:

Canard did holeshot both the Ryans.

you can make up for a certain amount of poor motor design by designing a pipe to fix it.

I just thought they missed the old expansion chambers so they are trying a new look.

It is a Honda grab bar in case the rider gets upside down he can grab that header and flip the bike over or land like a parachute if he cannot. That thing is really ugly could knock off a rider trying to pass if it were higher.

they probably use different header pipes to suit the different tracks.

keep in mind the pipe is coming from the left instead of the right

Yes that's what I was thinking. If so, I wonder what limits their spread of torque without the super long header? The massive throttle body and intake? Do AMA pro SX rules require teams to stick with mostly stock heads and intake designs?

Another way to look at it is what do the green and yellow teams think about it. Do they think "poor suckers with that ugly grab handle or foot step"? Or do they think "maybe we want one of those"? Perhaps the blue teams just dont look at it, because they cannot fit a longer pipe even if they want one.

I believe as long as you stay within the displacement rules, the sky is the limit on the engines. In January my son bought an 09' CRF250 that was Vince Friese's supercross bike from last year. But the motor in it was the motor that Motoconcepts/MDK ran in his bike for the last two races of the outdoor nationals last year. It was done by Allen Brown. The weather finally allowed him to ride it outside a little this week. I took it down the gravel road by the house today and I was speachless. If you would have blindfolded me and just threw me on the bike without knowing what it was, you would of had a hard time convincing me it wasn't a 450. The thing was amazing. Hit really hard down low and pulled like an SOB throughout. You could easily carry a gear higher than stock anywhere. It's no wonder the top couple guys in the lites class can turn as fast a lap times as the 450 guys.

I'd be pretty pissed if I owned an 09 or 10 crf450 and saw this picture, having to have the head pipe drag the ground to obtain peak performance. There is no way any of us could run a pipe like that, it would be destroyed in no time.

MAX!!!

I only dream of what it would be like to ride the factory 450's
Too true.

Neglecting engines and pipes, I was really impressed with how TC#38 and KW#14 suspension appeared to be working for them on Atlanta and Daytona. I know those guys are smooth, but there was also something freaky good about their suspension. Is that FC gear and not American Honda?

Canard's pipe is a joke. Image it on a rocky MX track, or in a multi rider pile up and that glowing hot pipe is nicely tucked into your back or neck.

I'd like to see a pipe that long on the new Yamaha. lol

The header pipe on the new Yamaha is actually longer than the header pipe on previous model years from 09 down.

      Hi Guys ,
      I'm in Australia and i am going to stream RBSR online , Red Bull site says start is 11:30 AEST ( Australian eastern standard time ) on the 20th Saturday
      which i don't think is correct . if it is on the 20th of Oct in the U.S at 1:30pm (racing must be about 4-5 pm) start on Saturday and Australia being 17 hours ahead wouldn't that make it a Sunday the 21st broadcast ?

      Growing up, seeing motovans at the track was possibly one of the coolest things.. while I was sleeping in my singlecab pickup. But hey, at the time, in highschool, my truck was cooler than some van. Now at this "age" 24... a van is quite a dang good idea, so I started looking. After a few facebook pots, a buddy of mine knew someone who had a 2001 E350 Passenger van sitting, and would get me a price. he told me it needed a radiator, and the spark plug blew out of cylinder 4 (common 5.4 triton issue). A few days go by, and he calls saying I can have it for FREE! they just needed it gone! So, I go out there with a friend of mine who has a 30ft gooseneck, and some starting fluid to make sure I don't get in too deep... we cant get it to fire without starting fluid, and ruled it out to a fuel pump. We pull the van on the trailer, stop by the parts store, and are headed home.


      The van was sitting stationary for 4 years... and smelled like it. but we'll get back there.. We dropped the tank, having to cut one of the tank straps and emptied the 4 year old fuel, put a new fuel pump in it, about 5 gallons of premium race fuel (fast and furious), and she fired up.  Next was the spark plug issue, I tapped the threads, and installed a helicoil along with new plug and coil pack, and we were good. Later I replaced the radiator after flushing the coolant system.

      The next day, we pulled out everything behind the first row bench seats, to include the headliner, rear AC duct, and side panels. Had to cut out the old seat belt mounts, and reinstalled the last bench where the first bench originally resided, since it was longer, but a few inches back to have optimal leg room. Then came the wall install... after lots of measuring once and cutting twice... I got it all figured out, and had the wall installed, then yellow stuffed "expanding foam" around all sides to ensure I wouldn't have fuel fumes in the cab. Finally I installed some flooring, just to give the bare metal some protection.
       
      After that, I was king of burned out on the van, before I even used it. She sat in my driveway for months before I was ticketed for having an unregistered vehicle parked outside.. gotta love florida.. I posted it forsale for a few days, then decided I would getRdone.

      So, off to the DMV, registered, and custom plates reading "MOTOVAN". Picked up a heavy duty cargo lock, fuel treatment, tons of black ice "little trees", and some R-134 to recharge the AC. She was making her first trip to the track that weekend!

      We changed the oil, 1,000 miles and 3 years overdue... only 2qts came out.. and sea foamed the green monster. After driving all over town, I parked in the driveway for a second, only to try to move it, and nothing on start up... not even after a jump.. so back to the parts store for a starter. After one of the worst starter jobs ever, she was cranking again. I figured we were problem free... but not before a brake line failed, and had to replace that guy, in order to take her to the track in 2 days!

      Finally! we were all clear, and we loaded three bikes into the van, and we were off! Two bikes is preferred.. but three worked, juts had to put most of the gear in the cab. Was a great day of riding, before a buddy crashed and ended the day with a concussion and a few compressed vertebrae..

      The van made another trip out this past weekend, and developed a new misfire, that ill be taking care of this week, and rechargeing the whole AC system since ill be sleeping in it this weekend for my first race in years!

      I will add some photos off my phone in a bit, until then, here is my youtube channel I created for the motovan!

      2019 Supercross season is near. Your "flavor fave" just took the MEC after being waved bye for the win.
      Same bet as last year..... $100 max customized jersey of your choice. First come first serve, but your ass BETTER pay up as others have to Mongo.
      I'm only taking the first "real" bet that approves my wager.... Tomac vs. the field 2019 SUPERCROSS. . He wins, you win. He looses, I win...... Who is the first taker? Anybody have the testicular fortitude? 
    • By Mongo134
      A friend of mine, BAHA, you know him, had a very good point I never thought of. All of these big $$ race purses are insured. Monster pays on insurance a percentage and should someone win the MEC as they did last night, the insurance company pays it out. 
      Now.... Had Savatgy just FUBAR'd in the sand like he should have to make the pass convincing that would be one thing. But since he was seen looking back several times to see where Tomac was at, caught slowing on camera on the backside of the track AND caught waving Tomac by to take the win.... I'm interested to see if insurance pays out or calls it a form of Insurance Fraud?

      I could be late but in the post race interview Tomac strongly hinted he will race the GPs at some point in his career. Maybe the incentive will pass but he sounded serious about it.
