Rd2 AMA Supercross - Phoenix. SPOILERS

[krad_nz]

Enjoyed the racing. Lots of spills.

Was interesting watching JS's face when the question was asked regarding the rear wheel speed sensor.

Surely they wouldn't be stupid enough to run some sort of traction control? No doubt just data logging.

[takitimu]

We are talking Larry Brooks here, you sure you want to say they would not that stupid ?

Unless one gets injured its looking like a js/rv fight, with cameos from reed and Trey, I actually thought dungey would go better.

in a car traction control works by both cutting revs and applying some braking - i dont think you could easily fit electronic braking control without noticing on an mx bike, and i think the consequences of cutting revs would outweigh the benefits - i.e. say during a jump, you give the bike some revs to get the nose up, but the wheel spins un-resisted (a classic traction control scenario) which would activate the traction control and cut the reves and/or apply the brakes - this wouldnt be fun while you were in the air. ditto for cutting on the inside of someone in the corner - sometimes you need just to get on the throttle, you expect a little wheel spin then it grips - if traction control cuts power before it grips, then you loose all speed and drive out of the corner. i think it would be highly unlikely that somehting like this would have any benefit for sx - maybe enduro but not sx.

but as for the 'sensor' im not even sure i think there was even one there - guess more will be revealed later

Yeah agree there. JS7 has ridden his whole life on a bike that breaks traction... Getting on to a bike with "traction control" would make for disaster. He looked super calm and relaxed. Quite frankly I think RV was riding outside of his limits trying to keep up (he has always had an aggressive style but he didn't look confortable, hence washing out the front)

I'd say Trey will be a force to reckon with. He's super fast and still really smooth, exciting to watch when he's on the dial.

Def gonna be a good season, i just pray they all stay healthy.

well Rossi and co in the moto gp rode bikes for a long time that broke traction as well, but are going faster than ever with traction control,

head over to VitalMX so see Larry Brooks's reply,

i do not think they would be running traction control with it that obicious, but putting that data logging gear on at the races was bound to cause at least chatter, and James did not do himself any favours on the way he answered it, but then i do not beleive he knows everything about every different part on his bike

They're clearing those triples far easier now too. :weird:

[scott411]

same basic principles apply to riding both types of bike, wheel spin equals slower times,

basic forms of tractions control have been put into mx bikes for a while, mostly just in the cdi, even back to some of the last of the 2 stroke 250's, they refer to these as passive control, active controls have speed sensors on the wheels and are far more advanced,

also some of the traction control systems use the brakes to limit the wheel spin as well,

i do not think that it would be a major difference to a mx bike, but i think at the top level where a tenth of a second or two a lap will mean the difference between winning and losing there is maybe the chance of an advantage,

[QUOTE=scott411;1129960080]well Rossi and co in the moto gp rode bikes for a long time that broke traction as well, but are going faster than ever with traction control,

Faster lap times but way less exciting to watch with all the electronics. Even most of the riders think things have gone to far.... Maybe next they could get rid of the riders and just use a couple of hydraulic rams and a few more sensors instead?:scratch:

[scott411]

no disagreement there,

put all motorcycle racing back on fire breathing 2 strokes, cost a shit load less as well

HELL YEA!!!! the days when to much throttle meant either the perfect drift or a thing called a "hi-side"...(dont think theres such a thing now?) and the word powerband use to scare the shit out of anyone who had to try ride one:baby:

when they start riding service honda/kawasaki 500 2t's. thats when we'll see some real racing! try hitting the whoops pinned in 5th on one of those psychotic beasts

I did ....throttle stuck

it hurt


( it was a jump actually so only the landing hurt )

Stephen

Off the top of my head I have seen two stage ignitions ( for two strokes) , and if they are fuel injected and four strokes , well then you can flick between maps , to achieve traction control

Bit of a write up about the traction control debate

[telliman]

js7 was playing when he replyed to erin bates, neither confirm nor deny and he took the oppertunity to put the cat amongst the pigeons, its good to see him riding with patience, thats wat chad and ricky did when james came on the scene, especially when they realised they couldnt match his speed, they chilled and waited for mistakes. wonder how long till rv and rd realise, cause i reckon james is just warming up!!

I agree. thats for the team to argu (Larry Brookes) James is the rider,

He's got a new trainer, Johnny Omara, that can also make alot of diffrence.
his old trainer Aldon Baker, is now RV trainer that could work in his favor.


JS7 washed out his front wheel in the heat race, RC said that could help James, pretty much, know how hard he could push the front end, better loosing it there, than in the main.

Go JS7

Aldon Baker is a very good trainer, his riders have either won sx championships of got hurt since the RC days, BT was trained by him when he won the east coast lites title in 07, i think him being in RV's corner is a big help,

i think this will be an awesome series, it may end up better than 06 when Chad, Ricky and James ended up within 3 points of each other

yep its looking great, would like to see RV get his title, but will be good either way.

If people are not watching, they are missing out

[Pierce]

cause i reckon james is just warming up!!

Gotta say I agree with you there. James has another two gears left in the tank that he can pull out when things get hairy (i.e. a bad start or crash) but RV kinda looked like he was riding above his limit when trailing behind James (who at the time was riding extremely conservativley). He seems to be gelling with the bike now unlike last season's opening rounds and even more so he's hungry for the title.

Canard is the one i'm thinking will start to make moves this year.

It seems each week i'm just hangning out for the next round to be online. The Dodger stadium round should be good (pretty big venue).
