MotoGP 500

[Hillbilly]

That's why I think they should be competing against other 500s and not the 4-stroke Superbikes. Don't know about the Superstocks though.

[gav]

Anyway, the two strokes have been allowed to compete in MotoGP up until now, but are banned from 1st January 2007. Didnt WCM drag a couple of old YZR500's out of a display last year? Didnt even qualify....

[madkeenandy]

Yeah, but that's bhp. The NSR 150 puts out about 40hp.

only 37

[F5 Dave]

Well seemingly a little over 20.

With a Tyga pipe & jet kit almost touches 30. Haha manufacturer's claims are such lies.

The lower curve is stock & the upper curves are with pipe & with pipe & jetkit.

[madkeenandy]

Yer they reckon the fxr has 20hp i'll know after tonight when tony puts his on the dyno, i reckon it might put out 15 if the dyno was feeling optimistic

So if these are the real power figures on a dyno, where to themaufacturers get their figures? The NSR 150's are plentiful over here, but always sold as having 40hp. That includes privately.

I've never ever seen a NSR 150 in NZ, thought they never got here

edit: whoops sorry Hillbilly thought you were in NZ, duh....

[F5 Dave]

Well maybe the 20ish one is a restricted version & the main restriction is in the pipe that they change for other markets, which is why the Tyga pipe made so much diff. But would only be high 20s real world unrestricted.

The manufacturers dyno them to get the brochure number (probably the best of several) on an optimistic dyno & then work out how much loss occurs through the gearbox etc, usually about 22%. Erm lets check my math, = 31.2hp, so they had to find a real good one & dyno it unrestricted on an optimistic dyno.

All quite feasible, but all complete bull.

[Hillbilly]

Yeah, it's amazing what's what's available. That includes RVF400's, TZR 250s,
CBR 250RRs, Aprilia RS 250s and so on. They're all ex-asia but not cheap. The RVF 400 is about $9,000 AUD along with the Aprilia RS 250. The others go for anywhere between $4,800 AUD to $6,900 AUD. Then there's the ORC which vary from State to Sate along with the road rules. (Or should I say roools)

[Motu]

All quite feasible, but all complete bull.

But as all manufacturers do it,it's a relative test and the numbers can be compared to other numbers with reasonable accuracy.If some clown used rearwheel hp figures they'd never sell a bike.Rear wheel hp is good if you are comparing the same bike on the same dyno,different bikes on different dynos are something you can't compare.

[F5 Dave]

Well it's the same with weight; a 166kg GSXR750 weighs 207 full of gas & ready to ride, it all just reeks of lies on top of the lies.

They all need to come with a lie sheet & a declaration of how much they are lying.

My head hurts.

Whats your dodgy old dad up to?, trying to find some more HP before the BOB?

I've seen one on trademe, but it was a while ago

Nah Peter Knapton was taking his out, dad wanted to compare them.

Just got back, the standard FXR has the grand amount of 13.5 HP
While Peter's has 15 and has huge amounts of talk starting way before dad's in the rev range, and the little line stays up there when the line for the standard FXR drops (after 10,500 rpm to redline)

It'll be interesting to see how it goes at BOB, i doubt it'll keep up with DC tho.

Knaptons bike is no faster than any of the other FXR out there though and has had his arse kicked by a few of them

DC's bike has 18hp and is a lot lighter

There have been a few NSR150SP's in New Zealand, not sure if they were imported officially though. A guy from Nelson raced one at Ruapuna for a season, he also raced a R1 in F1 (Daniel Jansen, you'd know him Kick?)
