Yeah that Cycle World article on the Tiger was cool indeed. I think you hit it on the money with the reference to the motoGP displacement. According to the rules on engine configuration they allow three cylinder motors, as long as the bike meets the weight and displacement requirements. I believe Aprillia...correct me if I am wrong has been racing triples for a while. I hope Triumph makes an 800cc motor it would be cool too add them to the mix :wink:On 2006-12-13 21:44, kuhlka wrote:
Isn't the new MotoGP class 800cc? Hint hint.
I'm thinking this; it only took Triumph 2-3 years to R&D the 675 according to various magazine reviews of the tech and development behind the 675. From what was said about the 1050 Tiger team being switched to the Tiger from a 'Busa killer project' I have to think Triumph has a very mean bike hiding in the shadows.
Perhaps they'll suprise the hell out of us next fall.
I will argue this a little bit (not much). The 1050 is certainly capable of more HP, and perhaps as much or more than the 955i Daytona. What's interesting is when you compare the cams between the two motors. The 955i Daytona has far more aggressive cams, for (you guessed it) higher RPM horsepower. The increased stroke isn't that much of a factor. As evidence, note that they both have about the same RPM limit.On 2006-12-14 05:39, welshrob wrote:
We won`t ever see a Daytona 1050. Why would Triumph make a new sportsbike that`s much slower than the old one? The bore and stroke of the 1050 motor has been developed for torque. It can`t be tuned to rev and put out the HP like the 955. A daytona 1050 would be no faster than a Sprint. The S3 is currently the highest HP 1050 in the range and it is still well down on the older engined 955 Daytona. If you`re wondering why I`m such a f*****G smartass, this question was brought up when I was doing the Q&A on the factory tour, so take it up with Triumph if you disagree!
It does hold water, longer strokes equal less horsepower at lower revolutions with more torque. Like you said, new technologies in metalurgy are improving max piston speed, but the guys with more than two cylinders will apply it to their motors as well, thus increasing their rpm redlines. As far as the DUC 1098, sure it has a longer stroke, but any inline 4 or V4 configuration will put it to shame.On 2006-12-15 20:59, 3forme wrote:
The theory of a longer stroke motor not being able to be made to produce more horsepower doesn't hold water. The trend lately (06) in MotoGP has moved a little toward longer strokes (Rossi's bike included). Also, look at the specs. on the new Duc. 1098. Yup, longer stroke and it has both high torque 'and' horsepower. They've even been able to push the 'maximum piston speed' up a little latley too. So, they seem to be learning more every year. They've also figured out how to get better mileage to go along with the higher horsepower. Technology marches on. :yayyy:
