Oh No - Transmission........ BOOM Maybe.

Still, look at what riders want . . . HP.

A huge % would not understand the difference twixt POWER and TORQUE.

Mathematically, horsepower equalstorque multiplied by rpm. H = T x rpm/5252, where H is horsepower, T is pound-feet, rpm is how fast the engine is spinning, and 5252 is a constant that makes the units jibe. So, to make more power an engine needs to generate more torque, operate at higher rpm, or both.

Cant have one without the other.

Agreed.

My F250 makes 500+ft/lb at around 1850 rpm and after that, as rpm rises torque begins to drop off. This is a Diesel engine though the dynamics are perhaps a bit different. I roll along at 50mph and 1300rpm pulling a 8,000lb boat like it's not even back there.

It seems to me that the R3 engine should kind of be like that making all that torque does not need huge HP to yield good smooth performance at a sub 3000 rpm level. As the rpm rises and hp rises the torque begins to fall off. I am perhaps wrong, but from the start I saw the rockets as being all about torque instead of HP.

This is why I wanted to try out the rocket, the torque. I really do not care at all about HP (well, at least not nearly as much). My first torque oriented bike was the Yamaha roadstar and I absolutley loved that low end pullaway low end low rpm torque. This machine was completely opposite from the GS1150 I had previously owned.

Turbo the rocket if you want more torque

I am good as it is. The mystery for me is why they geared it the way they did given the awesome torque the motor makes. I would just like a taller 5th gear . . . 80 mph at 2500rpm (peak torque curve) . . . the place where I will be letting her rip on the Highway. The goldwing does it effortlessly.
