REAR WHEEL HP

[WyldCFH]

Actually rider weight does. The heavier the rider the closer the power to weight ratio gets. Lets use your original numbers, then add a 200 lb rider.


Stock new R3 TFC plus rider 842/157 = 5.36
Stock new Diavel plus rider 681/139 = 4.90


That takes a .63 lbs/hp difference down to .46 lbs/hp difference, that's a 27% drop in the difference.
A 250 lb rider brings the numbers down to 5.68 and 5.26. That's a .42 lbs/hp difference.
It might take a 600 lb rider to make them even, but the rider weight does make a difference.

But, the rider has only been brought into it today, the numbers of bike v bike horsepower stand on themselves.

Yes, with the rider the gap closes, but 4 tenths heavier is still heavier. I am neither 600lbs or 200lbs... just under 200. Again, I posit that 99% of riders wouldn't notice the difference. Even in the extremes that @Claviger goes to lose bike weight and the power to weight ratio flops, you'd need a larger margin to notice.


Really, we should be arguing torque figures on this forum. It is where the R3 has every advantage over other bikes. And IF someone figures out a way to retune an Euro5 copliant ecu and raise the rpm, the R3 HP numbers will jump fro that alone and handily crush the VMax and Diavel

Bigger batteries, more windings on the motor!



Ahh, I already had hit the quote button, but @Steel beat me to it, rider weight affects the ratio more on a lighter bike than a heavier one, definitely.

Now with the extra 50 HP from a retune we have a DUCK HUNTER QUACK QUACK LOL

Hopefully someone will figure out how to tune the new ECU. Otherwise my stock Classic will out run them any day in a straight line.

SO with the additional 50 HP it wouid be 4.06 WOW DEAD DUCKS

YEP the old CLASSIC will be the SCUD missle

The TFC model does have different valves so it might be easiest to rev higher and have more hp gains.

How did you know that????

 

[WyldCFH]

Sooo....

TFC 29,000 USD
Diavel 1260 S 23,000 USD

You need to throw more money at a bike that already costs more to give it a chance?

At that price you can buy a Kwaka H2 with 207hp, easily and cheaply flash the ECU to 250ish

I was told by a friend of mine that has the TFC that it came with titanium valves.

They all have TI Valves
