was this put forth by the same publicity firm that touted the YZR-M1 as being "quicker and faster than the YZR-500" ??? we all know what a bunch of BS that was. i will bet my house right this very second that there is no friggin way that this thing puts out "more horsepower per cc" than the Kawasaki Ultra 150 or Yamaha GP1200 monsters. any takers? by the way, compare this thing to the direct injected models, and you can kiss quieter, more fuel efficient and less emissions goodbye
Well, the Ultra 150 has 123.3 hp/liter, and the GP1200R has 131.8 hp/liter. *IF* the new FX140 has 140hp (hence the name) and is 998cc, like an R1, then it will have 140.3 hp/liter. So yeah, when I find the actual specs for the FX140, I'll take that bet !!!
As for the $1000 savings in operating costs, you would have to use it quite a bit to SPEND $1000 in costs. Hmmmm.
I'm a little confused with the "claims"...Yamaha claims the FX140 is the "world's first" 4-stroke PWC, but Honda came out first.
Who has the "first" title? My guess is Honda because they introduced it first and to my knowledge, neither has a mass-produced 4-stroke PWC available at dealerships right now - The Honda will arrive at dealers roughly the same time as the FX140.
You're correct. Prop RPM is limited to around 2700 for aerodynamic reasons. Since the prop is usually attached directly to the crank, this limits engine RPM. The only way to make HP at low RPM is lotsa torque.
If the engine is geared, then high engine RPM/ lower torque works. Geared engines in aircraft have been problematic, but the latest 40s technology was used. Again, an application screaming for some new thinking and present-day technology.
The true "winner" can only claim their "prize" when their units arrive at the dealership for sale to the consumer. If Honda's units arrive at their dealerships first, they "win". Not that it really matters, except for corporate pride/bragging rights, and for propoganda like this article.
