Yamaha waking up?

I read that the 2015 Yamaha R1 is going to produce 230BHP.

Why is that waking up, stupid in my view, a way to get laws put in place to limit the maximum output or capacity rules?  :peepwall:

I agree, 230hp far too much to be used on the street, then again there may be method in the madness, and they are homologating for racing.
I fear that they are destined to follow the same path of early demise as the RZ500.
They sold like hot cakes and within 5 years there were almost none left due to guys having written them and themselves off.
Today finding an RZ500 is gold.

Must be some serious engineering - a Bugatti Veyron only produces 125 HP / L (1001 HP & 8L Engine) and that's at 16 bar turbo boost!  :o
If you can't fix it with a hammer, its an electrical problem!

I have seen the reports as well, but others speculate that it will be about 200bhp. Regardless, I had a highly modified Hayabusa that made 205 hp at the rear wheel, which equates to about 230 at the crank. It was easier to ride then my GSX-R, because the power delivery was more linear and predictable. It did however pick up speed at a rate that had to be experienced to be believed. At one stage I considered stretching it to 1500cc and adding a turbocharger, which would have yielded 400hp plus. Luckily I discovered that DS bikes were more fun.

Yamaha, although traditionally known as the king of 2-strokes, have also proven themselves to be superior to all in the 4-stroke world.

The only way I can see it making 230 hp is if it revs to 16000 rpm and produces maximum torque at about 15000. A 600 can do those revs, but the pistons speeds with a 1000 will be phenomenal, unless it is severely over square. I would not dismiss the idea totally though. 35 years ago 100bhp per litre was the holy grail for a litre class bike. Today it is 200.

Check at what revs a 450 single makes it max power, or worse, a 250 4stroke single. Piston speed is high. The MotoGP 1ltr bikes can put out 250HP.
Yamaha can easily produce a a liter class bike with the mentioned type of performance, especially considering that few, if any buyers, will ever take something like that to it's limit for more than tolerable periods of time.

True and interesting what you say about power 35 years ago, my Z1000[1976] produced 80HP. :-[......I would have my hands full with a 690 today.

I always like to read follow the speculation before a new bike is launched, because most of the time the press and everyone else get it completely wrong. Remember the Honda NR750 with the oval pistons and 8-valve heads? Rumour had it producing 200hp. When it was launched, it made 120.

230hp from a 1000cc machine is achievable. The 2014 Honda RCV1000R makes 235, but it is a privateer version of the factory MotoGP bike. You can lease it for R17 000 000 for one season. Add another R7 000 000 if you want a gearbox like the factory teams.

Closer to a production bike is the Honda CBR1000RR SP  WSBK bike. It produces 228hp. It is based on a production bike, but the amount of work and modifications to the bike (within the rules) puts the cost at twenty times that of one you can pick up from the showroom. These bikes also donít have to make concessions to service intervals, operating costs, low speed tractability and the user friendliness one expects from a road bike.

The other reason I believe 230hp is out of the question, is that they state it will have a crossplane engine. When it was launched, Yamaha stared that the inherently unbalanced nature of the engine and the large counter balancers restricted maximum horsepower, but that the nature of the delivery compensated for that. My guess is that they will either drop the crossplane concept for the new bike, or it will be restricted to about 190hp.

I hope Iím wrong though. I like it when a manufacturer stops plying cat and mouse and gives the competition a good ass kicking.

What they meant was, they are going to build a music instrument that produce 230db.

Take my advice; I don't use it anyway.

What for? :peepwall:

Valid question IMHO.

I lost it with the manufacturers and their push for ever more powerful superbikes almost 20 years ago. Started buying and riding smaller bikes in 1996 which to me are just as much fun to ride if not even more.

That dont impress me much.....

A decent DS bike from the blue stable will impress me though.

Glad they have seen their 2s strategy is a flop.

Still like their outboards, generators and musical appliances though.
